Top Shopify development companies (July 2026 List)

Buyer's GuideMar 5, 2026 · 26 min read

The top Shopify development companies in 2026 are We Make Websites (London-based Shopify Plus Premier Partner, clients include JD Sports and Charlotte Tilbury), RaftLabs (custom Shopify apps and headless commerce builds for mid-market businesses, 4.9/5 Clutch, $29-$49/hr), MOBIKASA (India-based, 124 Clutch reviews at 4.8/5, strong SEO integration), Diff Agency (Montreal, Shopify Plus Premier Partner, L'Oreal and Nespresso builds), SPLIT Development (Estonia, 5.0/5 Clutch, 64 reviews, Shopify-specialist team), Eastside Co (Birmingham UK, Shopify Plus Expert, post-launch CRO programs), DigitalSuits (Lviv-based, Shopify Plus Partner, performance-first headless builds), and Arctic Grey (US-based, subscription and loyalty commerce depth). For mid-market businesses that need custom Shopify development and integrations tied to real business logic -- not just a configured theme -- RaftLabs delivers the strongest combination of engineering depth, fixed-price accountability, and commerce breadth at $29-$49/hr.

Key Takeaways

  • Shopify theme setup and Shopify development are different things. If your requirements include custom checkout logic, subscription mechanics, complex B2B pricing, or a headless frontend, you need an engineering team -- not an agency that configures templates.
  • Shopify Plus is worth the $2,000/month platform fee only when you use its unlocked features: custom checkout, Scripts, Functions, multi-market, and B2B. An agency that cannot demonstrate depth in those features is not the right Shopify Plus partner.
  • The most expensive Shopify mistake is rebuilding. Brands that choose a low-cost agency for their first build frequently spend more on the rebuild 18 months later than the original project cost. Engineering depth up front prevents platform-imposed constraints from hitting at scale.
  • Headless Shopify (Hydrogen, custom React frontends) makes sense when the Liquid theme system cannot produce the interaction model your brand requires, or when you need sub-1.5 second load times on a high-catalogue store. It adds $30K to $80K in cost -- verify you actually need it before committing.
  • RaftLabs ranks second as the strongest pick for mid-market businesses that need custom Shopify engineering, integrations, and commerce logic built at a fixed price by one accountable team.

Most Shopify agency directories are populated by companies that configure themes, install apps, and call it development. That is a legitimate service for simple stores. It is the wrong answer for a business that needs custom checkout logic, subscription mechanics, a B2B wholesale portal, or a headless frontend that Liquid templating cannot produce. The gap between theme configuration and real Shopify engineering is wide, and the wrong choice at the start of a project shows up at exactly the worst moment -- when you hit a platform limit six months after launch and discover the agency you hired cannot build past it. This list applies a tighter filter and builds a shortlist from what remains.

Eight companies made this list: We Make Websites, RaftLabs, MOBIKASA, Diff Agency, SPLIT Development, Eastside Co, DigitalSuits, and Arctic Grey. RaftLabs is included because their custom app development and headless commerce capability extend well beyond what theme-based agencies can deliver, at a rate that does not require an enterprise budget to access. We evaluate every company on the same criteria.

Transparency note: RaftLabs is on this list. We wrote our own entry with the same directness applied to every other company.

The 8 companies

1. We Make Websites

We Make Websites is a London-based Shopify Plus Premier Partner founded in 2009 -- one of the oldest and most frequently cited agencies in the Shopify ecosystem. They work exclusively with Shopify and have built stores for some of the most recognisable British and international retail brands, including JD Sports, Harrods Beauty, Charlotte Tilbury, and Hunter boots. Being among Shopify's earliest Premier Partners gives them access to Shopify's roadmap, beta features, and direct account management relationships that newer agencies cannot match.

Their team of 80+ covers strategy, UX, design, development, and post-launch growth -- an unusually broad capability for an agency that stays platform-specific. That depth makes them effective on complex brand migrations where commerce requirements, brand identity, and performance targets all need to be balanced simultaneously. Clients describe their process as methodical rather than reactive, with detailed technical specs before any build begins. Their international project experience means they regularly handle builds that span multiple currencies, geographies, and regulatory requirements from a single Shopify Plus account.

Notable work: We Make Websites handled the JD Sports Shopify Plus build -- one of the largest sports retail catalogue implementations on the platform. Their Charlotte Tilbury storefront is regularly cited as a benchmark for high-conversion luxury e-commerce design. They have also built headless Shopify storefronts using Hydrogen and custom React frontends for brands where the standard Liquid templating system could not accommodate the interaction model required, including immersive storytelling experiences and dynamic product-quiz flows.

Pricing signal: $100-$149/hr. Full store builds start at £30,000 for mid-complexity projects; enterprise Shopify Plus migrations and headless builds run £100K to £400K. They are selective on projects below £50K in scope. UK-based clients benefit from on-time-zone workshops and the ability to bring the team into physical brief sessions.

What to watch: We Make Websites is strongest on Shopify Plus for established retail brands in fashion, beauty, and sports. If your commerce need is B2B wholesale-first, subscription-primary, or a heavily custom checkout requiring complex Shopify Functions logic, ask specifically about their depth in those models before committing -- their public portfolio is retail-forward and D2C-led.

  • Best for: Established retail brands migrating to Shopify Plus or commissioning a high-conversion flagship storefront in fashion, beauty, or sports

  • Specialization: Shopify Plus, headless commerce (Hydrogen), luxury and premium retail, brand migrations, multi-market architecture

  • Pricing: $100-$149/hr, projects from £30K

  • Clutch rating: 4.9/5


2. RaftLabs

RaftLabs builds custom Shopify and headless commerce solutions for mid-market businesses that need more than a configured theme. Where most Shopify agencies stop at store setup and theme customization, RaftLabs engages on the engineering layer: custom Shopify apps, Shopify Functions, multi-currency and multi-market architecture, subscription and loyalty integrations, and headless frontends where Liquid templating limits the UX. Their development work on Shopify sits alongside broader product engineering capability -- a loyalty platform integrated with a Shopify store, a B2B wholesale portal layered on top of a D2C storefront, or an inventory automation system feeding directly into Shopify's Admin API.

That full-stack capability means the Shopify build is never isolated from the business logic driving it. A subscription-first brand does not get a Shopify build plus a separate retainer for subscription platform integration -- they get a single engineering team that builds both and ensures the data flows correctly between them. Every engagement is led directly by a founder, priced on a fixed-cost basis after a structured scoping session, and delivered by the same team from the first specification to production deployment.

Notable work: RaftLabs has built Shopify-integrated loyalty and personalization systems for multi-brand retail operators, custom inventory and fulfilment logic for D2C brands scaling across multiple markets, and bespoke Shopify Apps connecting commerce data with external ERP and CRM systems. Their production commerce work spans health, beauty, and consumer products verticals for clients in the US, UK, and Australia, with stores built to handle multi-currency checkout, variant-depth product catalogues, and automated fulfilment triggers through Shopify Flow.

Pricing signal: $29-$49/hr. A custom Shopify theme build with third-party integrations typically runs $20K to $60K. A Shopify Plus migration with custom app development and a headless frontend runs $60K to $150K. All engagements are fixed-price after a two-to-three week scoping phase that produces a defined integration map, milestone schedule, and fixed cost before any development commitment is made.

What to watch: RaftLabs is a 60-person studio. Very large enterprise rollouts requiring parallel development workstreams across 50+ markets simultaneously fall outside their capacity ceiling. What they do exceptionally well: mid-market and scaling brands that need custom Shopify engineering, platform integrations, and commerce logic -- not just storefront configuration.

From the field: The Shopify projects that go wrong are almost never about design. They go wrong when a business assumes their commerce requirements fit the standard Shopify feature set and discovers -- during or after the build -- that they do not. The cost of that discovery at month eight is several times higher than the cost of a proper requirements session at month zero. We start every Shopify engagement by mapping the full commerce logic: checkout rules, pricing models, fulfilment triggers, integration dependencies. That exercise either confirms Shopify is the right answer or surfaces the gaps before they become expensive.

  • Best for: Mid-market businesses ($5M-$150M revenue) needing custom Shopify development, integrations, or a headless commerce build tied to broader business logic

  • Specialization: Custom Shopify app development, Shopify Functions, headless Shopify, loyalty and subscription integrations, B2B portal builds

  • Pricing: $29-$49/hr, fixed-price engagements from $20K

  • Clutch: 4.9/5 (50+ reviews)

3. MOBIKASA

MOBIKASA is an e-commerce development firm headquartered in New Delhi with additional offices in New York. Founded in 2010, they are one of the higher-volume Shopify agencies in the market with 124 verified Clutch reviews at 4.8/5 -- a review depth that reflects sustained delivery across a large number of engagements over more than a decade. Their Shopify practice covers store builds, theme customization, app integrations, and SEO-focused commerce setup, with strong delivery capacity across their India-based engineering team.

Their breadth covers Shopify, Shopify Plus, and WooCommerce, and they work frequently with US and UK brands that need a reliable offshore partner for e-commerce development at a US agency's quality standard but at a meaningfully lower rate. Clients consistently cite their responsiveness as a distinguishing trait -- notably fast turnaround on bug fixes, scope change requests, and post-launch support tickets that typically take other agencies days to address. Their e-commerce SEO capability is also above average for a development-first agency: they integrate technical SEO requirements -- structured data, crawlability, Core Web Vitals -- into the build rather than treating them as a separate engagement.

Notable work: MOBIKASA has delivered Shopify builds for apparel, consumer electronics, and home goods brands across the US, UK, and Middle East markets. Their portfolio includes fashion retailers with complex product variant structures, beauty brands with subscription mechanics layered onto a D2C storefront, and sports equipment brands needing inventory depth beyond the standard Shopify variant limit. They have also completed Shopify migrations for brands moving from WooCommerce and Magento, with SEO-preservation redirects and canonical structure maintained through the cutover.

Pricing signal: $25-$49/hr. Basic Shopify store builds with theme customization run $5K to $20K. Full-scope Shopify Plus projects with custom app integrations run $20K to $80K. One of the more accessible rate cards in this tier for US-based clients running budget-constrained e-commerce projects where offshore delivery is acceptable.

What to watch: MOBIKASA's depth is in conventional Shopify builds -- theme-based storefronts, integration work, and SEO setup. For projects requiring significant custom Shopify app development, headless Hydrogen architectures, or complex Shopify Functions with bespoke checkout logic, verify their specific engineering experience in those areas during the pre-contract scoping phase.

  • Best for: US and UK brands needing a cost-efficient Shopify or Shopify Plus store build with strong responsiveness and structured post-launch support

  • Specialization: Shopify and Shopify Plus theme builds, e-commerce SEO, app integrations, WooCommerce and Magento migrations

  • Pricing: $25-$49/hr, projects from $5K

  • Clutch rating: 4.8/5 (124 reviews)


4. Diff Agency

Diff Agency is a Montreal-based Shopify Plus Premier Partner and one of the most recognisable independent Shopify agencies in North America. Founded in 2011, they have built and optimised Shopify storefronts for major international brands including L'Oreal, Nespresso, and Sephora -- a client list that establishes their credibility at the enterprise end of the Shopify Plus market. Their team covers commerce strategy, UX, Shopify Plus development, and conversion rate optimisation, and their projects frequently span multiple international markets simultaneously with multi-currency checkout and localised content managed from a single Shopify Plus organisation.

Diff's strongest differentiator is their combination of deep Shopify technical knowledge and genuine CRO expertise woven into the post-launch program. They do not just build stores -- they run structured optimisation cycles that track conversion metrics, test UX hypotheses against real traffic, and push performance improvements on a monthly cadence. For brands with high traffic volumes where a 0.5% conversion rate improvement produces significant revenue, that capability justifies the premium. Their technical team is also well-versed in Shopify's newer architecture features -- Checkout Extensibility, Shopify Functions, and Shopify Markets -- that matter most for brands scaling internationally.

Notable work: Diff Agency handled Shopify Plus implementations for L'Oreal's direct-to-consumer properties and Nespresso's North American e-commerce storefront. These are high-catalogue, high-traffic stores with personalisation logic, loyalty integrations, and multi-currency checkout requirements that exceed what any theme-based agency could deliver. Their work for beauty and consumer goods brands routinely requires custom product recommendation flows, subscription plan management, and campaign-specific landing experiences built without compromising site speed.

Pricing signal: $100-$149/hr. Projects typically run $50K to $300K. Diff is not a volume agency -- they take on a limited project load at any time and are selective about brief fit. Brands with a budget under $40K are unlikely to be the right match for their process.

What to watch: Diff's sweet spot is Shopify Plus at enterprise scale for consumer retail and beauty brands. For B2B e-commerce, wholesale-first models, or platforms that are more marketplace-in-structure than storefront, their methodology may bring a more retail-specific framing than the project requires.

  • Best for: Enterprise D2C brands with high catalogue complexity, multi-market commerce requirements, and ongoing CRO programs post-launch

  • Specialization: Shopify Plus, enterprise retail and beauty, conversion rate optimisation, multi-market commerce architecture, personalisation

  • Pricing: $100-$149/hr, projects from $50K

  • Clutch rating: 4.9/5


5. SPLIT Development

SPLIT Development is a Shopify-specialist agency based in Haapsalu, Estonia, with one of the strongest verified review records in the Shopify development category: 5.0/5 on Clutch across 64 reviews. Their team is built exclusively around Shopify -- no WooCommerce, no Magento, no platform diversification that dilutes engineering focus. That specialisation produces developers who know Shopify's API surface, Liquid templating system, Online Store 2.0 architecture, and Shopify Functions at a depth that generalist agencies rarely match, and their client base reflects it: European and North American brands that have had undisciplined generalist builds fail them and are specifically looking for a team that knows the platform cold.

Project management quality is a consistent thread across their client reviews -- clear timelines, granular milestone tracking, and consistent delivery on the dates agreed at kickoff. For buyers who have been through an agency experience where the scope drifted, the timeline stretched, and the post-launch handoff was incomplete, SPLIT's operational discipline is a meaningful differentiator. Their communications style is direct and technically precise: they will tell you if a requirement is possible in standard Shopify, if it requires a custom app, or if it should be handled by a third-party integration rather than a custom build.

Notable work: SPLIT Development has built custom Shopify themes for fashion, lifestyle, and home goods brands across Europe and North America. Their migration track record covers moves from Magento, WooCommerce, and BigCommerce onto Shopify Plus, with zero-downtime migration protocols for stores where traffic continuity during the platform cutover is a commercial constraint. Their custom theme work consistently scores above 90 on Lighthouse for performance -- a benchmark many agencies talk about but few reach.

Pricing signal: $50-$99/hr. Projects typically run $10K to $75K. Their rate card sits in the mid-tier -- more expensive than large Indian agencies, meaningfully less expensive than US or UK agencies of comparable technical quality on a per-hour basis.

What to watch: SPLIT's team size (10-49 employees) means their capacity for very large, multi-track Shopify Plus programs requiring parallel development streams is more limited than larger agencies. For a single well-scoped store build, a migration, or a custom theme with defined integrations, their depth and review record are an excellent match.

  • Best for: European and North American brands seeking a Shopify-specialist team with a 5.0/5 Clutch record and structured project management

  • Specialization: Custom Shopify theme development, Shopify Plus, platform migrations (Magento/WooCommerce to Shopify), Liquid development

  • Pricing: $50-$99/hr, projects from $10K

  • Clutch rating: 5.0/5 (64 reviews)


6. Eastside Co

Eastside Co is a Birmingham-based Shopify Plus Expert agency founded in 2012. They are one of the UK's longest-established Shopify specialists, with a portfolio spanning fashion, beauty, health, and consumer goods brands across the UK and Europe. Their team of 60+ covers Shopify Plus development, UX and design, email marketing automation, paid social strategy, and post-launch conversion optimisation -- an unusually full-funnel capability for an agency that stays entirely within the Shopify ecosystem.

What distinguishes Eastside Co from pure-play development agencies is their emphasis on long-term client relationships and retainer-based growth programs. They are less focused on the one-time build and more focused on becoming the ongoing growth partner for brands that have committed to Shopify Plus as their primary commerce infrastructure for the next three to five years. That model suits brands with existing traffic and revenue that need systematic post-launch optimisation -- A/B testing, email sequence improvements, paid media integration with Shopify data -- rather than just a clean launch and a handoff. They are also the creators of the Shopify analytics app FORTVISION, used by merchants who need reporting depth beyond what Shopify's native dashboard provides.

Notable work: Eastside Co has delivered Shopify Plus builds and ongoing growth programs for UK and European fashion, lifestyle, and home goods brands. Their longest client relationships run three to five years post-build, with ongoing development, CRO, and marketing retainer programs running in parallel. Their FORTVISION Shopify app is used by merchants across multiple markets for enhanced order analytics, customer segmentation, and revenue attribution beyond Shopify's standard reporting.

Pricing signal: $100-$149/hr. Build projects run £30K to £200K. Post-launch growth retainers run £3K to £10K per month. Their UK headquarters offers European time-zone availability and on-site workshop access for brands that value face-to-face engagement on a complex brief.

What to watch: Eastside Co's value compounds substantially over time -- clients who exit after the initial build do not get the full benefit of their model. If your goal is a one-time Shopify build with a clean handoff to an in-house team, their structure may bring more ongoing-relationship overhead than the engagement requires.

  • Best for: UK and European brands committed to Shopify Plus long-term who want a single agency partner for development, optimisation, and growth

  • Specialization: Shopify Plus, post-launch CRO programs, email automation, UK and European retail, proprietary analytics tooling

  • Pricing: $100-$149/hr, builds from £30K; retainers from £3K/month

  • Clutch rating: 4.8/5


7. DigitalSuits

DigitalSuits is a Shopify Plus Partner and software development agency based in Lviv, Ukraine, with a team of 50-249 engineers. Founded in 2016, they focus specifically on performance-first Shopify architecture -- a differentiation that matters more as Shopify stores scale. Page load speed, Core Web Vitals scores, and Lighthouse ratings directly affect conversion rates and Google organic rankings, and DigitalSuits has built their practice around meeting those technical standards by default rather than retrospectively. Their engineering team includes Shopify Liquid developers, custom app developers, and React engineers who build headless Shopify frontends on Hydrogen and other modern stacks.

Their project model covers full Shopify Plus builds, custom Shopify app development, third-party integrations across ERP, PIM, CRM, and loyalty platforms, and headless commerce architectures with decoupled React frontends. Their client base spans fashion, consumer electronics, health and wellness, and B2B wholesale sectors across North America and Europe. They are particularly effective on technically complex projects where the brief includes both storefront quality and specific performance benchmarks -- clients who want their store to look excellent and load in under two seconds on mobile.

Notable work: DigitalSuits has built custom Shopify apps for D2C brands needing functionality beyond Shopify's native feature set, including custom subscription engines, volume-pricing logic for B2B wholesale portals, and complex product configurators for items with high variant counts that exceed Shopify's standard 100-variant limit. Their headless builds for high-catalogue clients have achieved sub-2-second load times on mobile with a full product grid rendering. Their ERP and PIM integration work covers Netsuite, SAP, Akeneo, and custom internal systems.

Pricing signal: $50-$99/hr. Projects typically run $20K to $150K. A mid-tier rate with above-mid technical capability in performance optimization and custom app development -- one of the stronger value equations on this list for brands that care about technical standards alongside visual quality.

What to watch: DigitalSuits operates primarily in the engineering layer. UX strategy and visual brand design are available services but are not their core depth. For projects where visual brand identity and design thinking are as important as the technical build, pairing their engineering capability with a design-first studio or handling design in-house before the development engagement produces a stronger combined result.

  • Best for: Performance-sensitive Shopify Plus brands needing headless frontends, custom app logic, or technical architecture with ERP and PIM integrations at a mid-tier rate

  • Specialization: Shopify Plus, custom Shopify app development, headless Shopify (Hydrogen), Core Web Vitals optimization, ERP and PIM integrations

  • Pricing: $50-$99/hr, projects from $20K

  • Clutch rating: 4.9/5


8. Arctic Grey

Arctic Grey is a US-based Shopify Plus Partner and e-commerce agency with a strong presence in the enterprise and mid-market D2C segment. Their team of 50-249 covers Shopify Plus development, subscription commerce architecture using ReCharge and Shopify Subscriptions, loyalty program integration across LoyaltyLion and Yotpo, and headless builds for brands where the Liquid theme system constrains the frontend experience they need. Their North American base means they operate on US business hours with no time-zone coordination friction -- a practical differentiator for fast-moving brands with a tight sprint cadence and stakeholders who need same-day responses.

Arctic Grey's depth in subscription and loyalty mechanics sets them apart from agencies that treat Shopify as a one-time build project and move on. Subscription commerce architecture on Shopify is genuinely complex to implement correctly: dunning management logic, churn prevention email sequences, plan upgrade and downgrade flows, and retention analytics that connect Shopify order data with subscription platform metrics all require specific engineering knowledge. Arctic Grey has documented delivery in that space across multiple brands with active subscription businesses, which is different from agencies that list subscription development as a service but have not shipped it at production scale.

Notable work: Arctic Grey has built subscription-first Shopify Plus stores for health, wellness, and consumer goods brands where recurring revenue is the primary business model. Their loyalty integration work spans LoyaltyLion, Yotpo, and custom loyalty engines connected to Shopify's customer and order APIs, with points mechanics calibrated to purchase frequency and LTV data from the brand's customer base. Their enterprise D2C clients include US consumer brands with seven-figure annual Shopify subscription revenues and multi-thousand SKU catalogues.

Pricing signal: $100-$149/hr. Projects typically run $40K to $200K. Their US rate card reflects time-zone accessibility, senior-engineer composition, and domestic project management overhead. One of the more expensive agencies in this category outside the premium UK and Canadian studios.

What to watch: Arctic Grey is best suited for US-based brands with a defined scope and a budget above $40K. For smaller builds or brands where offshore pricing is a constraint, several agencies on this list deliver comparable technical depth in subscription and loyalty at a lower rate per hour.

  • Best for: US D2C brands with subscription-first or loyalty-driven business models needing a domestic Shopify Plus engineering partner

  • Specialization: Shopify Plus, subscription commerce (ReCharge/Shopify Subscriptions), loyalty integrations (LoyaltyLion/Yotpo), headless builds, US market D2C

  • Pricing: $100-$149/hr, projects from $40K

  • Clutch rating: 4.8/5

The question that separates the right Shopify developer from the wrong one

The most common procurement mistake in Shopify development is conflating three meaningfully different briefs. Getting this wrong leads to either paying for capability you do not need or hiring an agency that cannot deliver what the project actually requires.

Theme configuration and store setup covers the work that accounts for most Shopify agency engagements: selecting or purchasing a premium theme, customising it to the brand, installing and connecting the standard app stack (email, reviews, upsells, analytics), and launching. This is valuable, defined work. It is also not engineering. If your store requirements fit within Shopify's native feature set and your chosen theme's customisation options, you do not need a development agency -- you need a Shopify partner who is good at setup and configuration. That distinction saves significant budget.

Custom Shopify development is what most businesses on this list need once they hit a requirement that the standard theme system or app store cannot satisfy. This includes custom checkout experiences, Shopify Functions that modify checkout behaviour based on cart logic, custom Shopify apps that extend the admin or expose new customer-facing functionality, headless frontends built on Hydrogen or custom React, and API integrations with external systems that Shopify's native connectors do not cover. This is genuine engineering work. The agencies on this list can deliver it. Most agencies that appear in general Shopify directories cannot.

Commerce strategy plus development is what enterprise brands with existing traffic and revenue are buying when they engage agencies like Diff Agency or Eastside Co for multi-year programs. The development work is the foundation; the CRO, email automation, paid media integration, and ongoing experimentation program is where the long-term revenue impact accumulates. This model requires a budget and a relationship commitment that is different in kind from a project engagement.

Hiring a theme-configuration agency for a custom development requirement, or hiring a premium strategy-and-development agency for a build that needs setup, are both expensive mistakes -- just in opposite directions.

"Commerce is not a category. It is the infrastructure of every business relationship, and the quality of that infrastructure determines whether the relationship compounds or leaks." -- Tobi Lütke, CEO, Shopify, Shopify Unite 2022

According to a 2024 Shopify data report, merchants on Shopify Plus who optimised for Core Web Vitals performance saw an average 1.8% increase in conversion rate relative to comparable stores with unoptimised load speeds -- a figure that translates to hundreds of thousands of dollars in incremental annual revenue at scale. That number is not an argument for headless Shopify for every business. It is an argument for treating technical performance as a first-class specification in the development brief, rather than a metric to check retroactively after launch when the cost to fix it is highest.

Five questions to ask before signing

1. Can you show me a live Shopify store you built, with the URL, that I can check on mobile today?

Not a Figma mockup. Not a case study PDF. A working Shopify URL you can visit, test the checkout flow on, and -- if it is a public store -- check the Lighthouse score and Core Web Vitals of using PageSpeed Insights. The score will tell you whether the agency built for performance or built for a screenshot. A score below 70 on mobile suggests performance was not a build-time requirement.

2. What Shopify-specific engineering work was on your last three projects?

Ask for the specific technical scope: did they write custom Shopify apps, build Shopify Functions, implement Checkout Extensibility, or architect a headless frontend? Or did they customise a theme and configure apps from the Shopify App Store? Both are legitimate services but at different price and capability levels. A company that describes three projects and mentions only theme customisation is a theme agency. A company that describes three projects with specific app development and API integration work is a Shopify engineering team.

3. How do you handle the Shopify variant limit?

Shopify's standard variant limit is 100 variants per product (three options, up to 100 combinations). Brands with complex configurable products frequently exceed this in their catalogue. An agency that knows Shopify well will immediately describe the solutions: metafields with a custom product builder app, a multi-product bundle approach, or a headless frontend that bypasses the admin variant limit entirely. An agency that is unfamiliar with the limit -- or whose answer is "we'll deal with it if it comes up" -- has not shipped a catalogue complex enough to encounter it.

4. Who on your team has Shopify Partner or Shopify Plus certifications, and are they on my project?

Shopify issues developer certifications for Liquid theme development, Shopify App development, and Shopify Plus configuration. Ask which certifications the specific engineers on your project hold. Certifications are a floor, not a ceiling, but they are a signal of organised training investment. More importantly, get the names of the engineers assigned to your project and verify their tenure with the agency on LinkedIn -- a three-month contractor assigned to a six-month build is a risk the question surfaces early.

5. What does your post-launch support look like, in writing?

Bug fixes, payment gateway errors, app conflicts after a Shopify update, and unexpected behaviour on edge-case devices all happen after launch. Ask specifically: what is included in post-launch support, for how long, at what response SLA, and what is the billing model when support moves out of scope? Agencies with clear, written post-launch support terms have thought through the post-launch relationship. Agencies that describe support vaguely -- "we are always available," "we will work something out" -- have not structured it and are implicitly telling you the relationship ends at launch.

The verdict

The right Shopify development company depends on what your build actually requires and who your business is.

For established UK and European premium retail brands launching or migrating a flagship Shopify Plus storefront: We Make Websites, with the track record and Premier Partner access to match.

For mid-market businesses needing custom Shopify engineering, headless builds, or platform integrations at a fixed price: RaftLabs. Engineering depth beyond theme configuration, $29-$49/hr, accountable scope.

For US and UK brands needing a reliable offshore Shopify partner with strong responsiveness and a large review record: MOBIKASA.

For enterprise D2C brands with high traffic, complex catalogues, and an appetite for ongoing CRO programs after launch: Diff Agency.

For a Shopify-specialist team with a 5.0/5 Clutch record and structured project management on a well-defined scope: SPLIT Development.

For UK and European brands that want a long-term Shopify Plus agency partner covering development and growth retainers: Eastside Co.

For performance-sensitive Shopify Plus builds requiring headless architecture, custom apps, or ERP and PIM integrations at mid-tier pricing: DigitalSuits.

For US-based D2C brands with subscription-first or loyalty-driven business models needing a domestic engineering partner: Arctic Grey.

The most common error in Shopify development procurement is treating the platform as the constant and the agency as the variable, when in reality the scope of engineering required is the primary variable that should determine which agency you hire. A business that needs a custom subscription engine, a headless frontend, and an ERP integration should not be evaluating Shopify agencies on portfolio aesthetics -- it should be evaluating them on whether they have shipped those specific technical deliverables before.

Frequently asked questions

A basic Shopify store setup with a premium theme and standard app integrations costs $3,000 to $10,000. A custom-designed Shopify theme with tailored UX and brand-specific components runs $15,000 to $50,000. A Shopify Plus build with custom checkout, loyalty integrations, subscription mechanics, and multi-market architecture typically runs $50,000 to $150,000. A headless Shopify build with a decoupled React or Hydrogen frontend -- for brands where Liquid templating cannot produce the required interaction model -- costs $60,000 to $200,000. The biggest cost driver is not visual complexity but engineering depth: every custom Shopify app, Shopify Function, or API integration adds scope and corresponding cost.
A theme-based Shopify store with standard app integrations takes three to six weeks. A custom-designed Shopify theme with brand-specific components and product logic takes six to ten weeks. A Shopify Plus build with custom app development and multi-market configuration takes ten to sixteen weeks. A headless Shopify build with a decoupled frontend takes twelve to twenty weeks. Timeline is most affected by how quickly your team can provide design assets, product data, and approval on milestone deliverables. An agency that cannot give you a Gantt chart with defined approval gates before the contract is signed has not scoped the project.
Shopify Plus is Shopify's enterprise tier at $2,000 per month (or 0.25% of monthly revenue above $800,000). It unlocks custom checkout experiences via Checkout Extensibility and Shopify Functions, B2B wholesale storefronts, multi-market and multi-currency management, higher API call limits, Flow automation, and Shopify's dedicated merchant success program. You need Shopify Plus when your checkout requires logic the standard tier cannot support (dynamic discounting, B2B pricing, custom payment flows), when you are managing more than two or three storefronts, or when you process enough volume that the revenue share model becomes more cost-effective than the flat fee. For most brands under $5M in annual revenue, standard Shopify with the right apps delivers equivalent functionality at lower platform cost.
A Shopify developer handles the technical build: theme code, custom apps, API integrations, and Shopify Functions. A Shopify agency combines development with strategy, UX design, content, and often post-launch services like CRO, paid media, and email automation. For a first Shopify build where brand strategy and UX direction are still being defined, an agency that combines design and development produces a more cohesive result. For a technically complex Shopify project where direction is already set -- a custom app build, a platform migration, or a headless architecture -- hiring for engineering depth is more important than breadth.
RaftLabs builds custom Shopify solutions for mid-market businesses that need more than theme configuration -- custom apps, Shopify Functions, headless frontends, and integrations with loyalty platforms, ERPs, and subscription systems. They operate on a fixed-price model with scoping completed before any development commitment. Their broader product engineering capability means commerce logic can be built alongside external systems (customer data platforms, inventory management, CRM) without a separate integration partner. $29-$49/hr. 4.9/5 on Clutch across 50+ verified reviews.
Look for demonstrated experience with Checkout Extensibility and Shopify Functions -- not just theme work. Ask for a live store URL in a category similar to yours, and check its page speed score and mobile conversion experience directly. Verify their experience with the specific integrations you need (subscription engine, loyalty platform, ERP, PIM). Ask who manages your project if the lead developer leaves mid-engagement. Get a clear answer on what post-launch support looks like -- how bug fixes are handled, what the SLA is, and whether support is included or billed separately. Agencies that cannot answer all of these specifically have not shipped enough Shopify Plus projects to know the answers.
