Ecommerce software development company

Custom ecommerce software for online retailers, subscription businesses, B2B sellers, and marketplace operators who need a platform built around their specific catalogue, checkout, and fulfilment model, not a Shopify theme or a SaaS plan that covers 80% of the requirement.

When your product configuration, bundle logic, B2B pricing rules, subscription mechanics, or multi-vendor marketplace requirements can't be modelled without significant compromise on a standard platform, we build the system that fits the business rather than the other way around.

  • Custom ecommerce platforms with product catalogue, checkout, order management, and fulfilment workflows built for your specific inventory model

  • Multi-vendor marketplace development with seller onboarding, commission management, and payout automation

  • Headless commerce architecture decoupling your storefront from your backend so content teams and developers work independently

  • AI personalisation and recommendation engines that increase average order value and repeat purchase rate from your existing traffic

The problem

Sound familiar?

  • forcing complex product configurations, bundle rules, or B2B tiered pricing into a SaaS ecommerce platform that wasn't designed for them, and paying developers to maintain workarounds every time the platform updates?

  • running separate tools for product catalogue, inventory, subscription billing, and fulfilment that share no data and require manual reconciliation between every order?

Short answer

RaftLabs is a custom ecommerce software development company building platforms, multi-vendor marketplaces, headless storefronts, subscription commerce, AI personalisation, and B2B ordering portals for online retailers and B2B sellers. We scope every project before pricing. Fixed cost, agreed before work starts. Most teams launch a validated v1 in about 10 to 16 weeks, then iterate.

When the platform becomes the ceiling

Shopify, WooCommerce, and Magento cover standard ecommerce well. They handle product listings, a standard checkout, basic promotions, and a handful of payment gateways. The ceiling appears when the business model requires something the platform wasn't designed to support. Complex product configurations with dozens of interdependent attributes. B2B pricing tiers per account. Multi-vendor marketplace logic with seller-specific fulfilment and split payouts. Subscription mechanics with custom box curation. Or a catalogue size that pushes the platform's performance and API rate limits. At that point, the choice is maintaining expensive developer workarounds that break on every platform update, or building a system designed for the actual business model from the start.

We build ecommerce software for businesses at this decision point, and for those that have already reached it after launching on a standard platform. We've built custom ecommerce platforms, multi-vendor marketplaces, headless commerce frontends, subscription commerce systems, and B2B ordering portals. The operational requirements specific to ecommerce: catalogue attribute flexibility, checkout conversion, inventory accuracy across locations, payment processing reliability, PCI-DSS scope for how card data is captured and stored. The integration landscape between your ecommerce platform, warehouse management, ERP, and 3PL systems. All designed in from the start, not retrofitted later.

01 Diagnosis

Where ecommerce software usually breaks

  1. 01
    Problem

    Apps slowly become a tax on growth

    Solution

    For small and medium ecommerce brands, apps slowly become a tax on growth. $9 here, $15 there, $29 for advanced features. When the product range includes items with attributes that don't fit the platform's standard catalogue structure, configurable dimensions, interdependent options, custom engraving fields, every new product type requires developer involvement to work around the data model. Every workaround adds fragility and slows down the merchandising team. A custom catalogue built around the actual product range removes that constraint, so product teams can add new types without waiting on developers. The outcome is merchandising without the app tax.

  2. 02
    Problem

    It felt like a toll booth

    Solution

    One candle merchant described leaving Shopify this way: a monthly subscription fee plus a 2% transaction cut on every single sale, on top of payment processor fees. It didn't feel like a partnership. It felt like a toll booth. Standard checkout flows are designed for a single buyer purchasing a standard product with a standard delivery address. When your actual customers are B2B buyers on account terms, subscription customers managing recurring orders, or buyers configuring complex products, the standard checkout creates friction at the point of purchase. A checkout built for the actual buyer type cuts abandonment at precisely the point where standard platforms let revenue slip through. The outcome is a checkout built for your buyer.

  3. 03
    Problem

    This patchwork stack works, until it doesn't

    Solution

    Most brands at this stage are cobbling together a mix of tools: a storefront like Shopify, a 3PL portal, some QuickBooks entries, a spreadsheet for inventory, maybe a Slack message to remind someone to send a tracking number. This patchwork stack works, until it doesn't. Finance teams manually copy invoices from Shopify and cross-check with Stripe, then reconcile everything in Excel. The sync layer between platform, warehouse, and ERP produces a different version of the truth in each system. An integrated order management layer connecting the ecommerce platform, warehouse system, and ERP gives every team a single accurate view of stock, orders, and fulfilment status in real time. The outcome is one version of the truth.

  4. 04
    Problem

    The storefront shows a third version of the truth

    Solution

    If your price list lives in one system, your sales terms in another, and your storefront shows a third version of the truth, the website is not the problem. Governance is. When B2B customers have negotiated pricing, credit terms, minimum order quantities, and multi-user approval workflows, and the ecommerce platform can't configure any of these per account, the sales team handles every B2B order manually by phone or email. That's a hidden cost that scales with revenue. A B2B ecommerce portal with account-specific pricing, purchase order terms, and buyer approval workflows moves the ordering process online without losing the account-level commercial relationship. The outcome is B2B ordering without the phone call.

02 What we ship

Ecommerce software we build

  1. Custom ecommerce platforms

    Custom product catalogue with configurable attributes and variant logic. Checkout with your specific tax, shipping, and payment rules. Order management with warehouse and fulfilment integration, customer account and order history, promotions and discount engine, and an admin your merchandising team can run without developer involvement. Best for retailers whose product configuration can't be modelled in Shopify without apps, businesses replacing WooCommerce or Magento with a maintainable custom platform, and brands with complex bundle or subscription mechanics that SaaS platforms can't support cleanly. The outcome is a platform that fits the catalogue.

  2. Multi-vendor marketplace development

    Seller onboarding and verification workflow, per-seller product catalogue and inventory management, commission and fee structure configuration, order routing to the correct seller, split payment and payout automation, buyer and seller dispute management, and marketplace analytics for operators. The architecture is designed so sellers operate independently while the marketplace operator has a single view of the entire operation. The outcome is a marketplace that runs itself.

  3. Headless commerce architecture

    API-first backend with the commerce engine, product catalogue, cart, and checkout decoupled from the frontend presentation layer. Custom storefront, typically in Next.js, with content management integration so marketing teams update pages without code, and performance-optimised frontend with Core Web Vitals scores that support organic search. Best for brands with high design and performance requirements that SaaS storefronts can't meet, and businesses running multiple storefronts from a single commerce backend. The outcome is a storefront that ranks and converts.

  4. AI personalisation and recommendations

    Product recommendation engine trained on purchase and browse history, personalised homepage and category page ranking, AI search that handles natural language queries, dynamic pricing recommendations by customer segment and demand signal, and abandoned cart recovery with personalised content. Best for ecommerce businesses with enough catalogue depth and traffic that personalised recommendations materially increase conversion. The outcome is existing traffic converted harder.

  5. Subscription and recurring commerce

    Subscription plan management with fixed and build-your-own box options. Recurring billing with multiple payment methods and smart retry for failed payments. Subscriber portal for pause, skip, swap, and cancellation self-service, churn intervention workflow triggered before a subscriber cancels, and subscription analytics covering churn rate, lifetime value, and cohort retention. The outcome is subscriptions that retain.

  6. B2B ecommerce portals

    Account-based pricing with customer-specific price lists and discount tiers. Quote request and approval workflow for large or custom orders. Minimum order quantity and bulk discount configuration, purchase order payment terms including net-30 and net-60, multi-user account management with buyer roles and approval limits, and integration with SAP, Microsoft Dynamics, or NetSuite. The outcome is B2B customers who reorder without calling.

03 Buy, build, or wait

The ecommerce software decision is usually about the platform: what it takes, what it locks, and what it can't do.

Stay on the platform

  • Shopify, WooCommerce, Magento

    When the catalogue is standard and the apps cover the gaps without becoming a tax.

Build custom

  • When apps become a tax on growth

    $9 here, $15 there, 2% off every sale. Owned software has no per-sale toll.

  • When the catalogue can't be modelled

    Strict 100-variant limits and attribute types the platform never imagined. Build the catalogue around the products.

  • When the stack is a patchwork

    Shopify + 3PL + QuickBooks + spreadsheets. One system of record instead of five versions of the truth.

Bottom line

Stay on the platform while it fits. Build when the platform taxes your growth or your catalogue outgrows its data model.

04 How we work

How we work with ecommerce clients

  1. 01

    Discovery

    We map the product catalogue structure, the checkout and fulfilment requirements, the integration landscape (ERP, warehouse, 3PL, payment gateways), and the operational workflows the platform needs to support. We identify where the current approach, whether a SaaS platform with workarounds or manual processes, creates the most friction. We agree scope and produce a fixed-price specification before development begins. The risk this retires: the integration the sales demo never showed.
  2. 02

    Architecture

    We design the data model around the actual product range and business model. That covers the catalogue attribute structure, the order and fulfilment workflow, the pricing engine (including B2B account pricing if needed), the integration architecture between the ecommerce platform and connected systems, and the admin layer for non-technical teams. Performance requirements for catalogue search and checkout are factored in before code is written. The risk this retires: the checkout that can't handle your buyer type.
  3. 03

    Build

    Two-week sprints with working software at each checkpoint. Core catalogue, checkout, and order management ships first. Marketplace seller flows, subscription mechanics, AI personalisation, and third-party integrations follow in subsequent sprints. The merchandising admin is built alongside the customer-facing product so both can be tested with real data. The risk this retires: the subscription migration that loses subscribers.
  4. 04

    Launch and optimisation

    We go live in phases, starting with a controlled product range or customer cohort before full launch. Monitoring is configured for checkout failures, payment errors, inventory sync issues, and order routing problems. Post-launch optimisation covers conversion rate, search relevance, recommendation performance, and integration reliability as order volume grows. The risk this retires: the launch that loses rankings without a redirect map.

09 Questions

Common questions

Shopify and WooCommerce handle standard ecommerce well and are the right choice for most businesses launching a direct-to-consumer store with a standard product range. Custom software becomes the right choice when the product catalogue requires attribute types and variant logic the platform can't model, or when B2B pricing tiers and account terms can't be configured per customer. Multi-vendor marketplaces with seller-specific fulfilment and commission structures are another trigger, as are subscription mechanics with box customisation the platform can't support. API rate limits and performance characteristics constraining catalogue size or integration architecture are the final sign. The decision usually comes at a specific complexity or volume threshold rather than at the start.

Yes. Multi-vendor marketplace development is one of our core ecommerce capabilities. We build the seller onboarding and verification workflow, plus per-seller product catalogue and inventory management. The order routing logic sends each order to the correct seller. Split payment and payout automation distributes buyer payments to sellers after commission deduction. We also build the operator admin layer for managing sellers, categories, commission structures, and disputes. Sellers operate independently, listing their own products, managing their own inventory, and fulfilling their own orders, while the marketplace operator has a single view of the entire operation.

Headless commerce decouples the storefront presentation layer from the commerce backend. The frontend is a custom application, typically built in Next.js, that fetches product, cart, and checkout data from an API rather than rendering pages through Shopify's or another platform's templating system. The result is a storefront with full control over performance optimisation, page structure, and content management, which typically produces significantly better Core Web Vitals scores than a theme-based storefront. The cost premium over a Shopify theme depends on the scope. We scope every project before pricing. Fixed cost, agreed before work starts.

We scope every project before pricing. Fixed cost, agreed before work starts.

Card data is the highest-risk asset in any ecommerce build. We keep cardholder data out of your own systems by tokenising through PCI-DSS compliant processors like Stripe, Adyen, or Braintree, so your platform stores order and customer data while the processor holds the card. That keeps most builds in the lighter SAQ-A compliance scope rather than full audit territory. On payment products where the platform touches card flows directly, we design to PCI DSS audit requirements. The exact scope is agreed during discovery based on how you take payment.

Yes. Most ecommerce builds connect to existing operational systems rather than replacing everything at once. We integrate with major ERP systems (SAP, Microsoft Dynamics, NetSuite), warehouse management systems, 3PL APIs, and accounting platforms (Xero, QuickBooks). We can also build a custom commerce backend behind your existing Shopify or WooCommerce storefront, so you keep the front end that works and replace the logic underneath. The integration scope is defined during discovery because it is usually the most complex part of a commerce build and needs to be right-sized before development starts.

A single inventory source of truth, usually your warehouse management system or ERP, sits behind every sales channel, and every sale updates the available stock figure immediately across all of them. The sync layer uses optimistic locking to handle concurrent updates: if two channels receive simultaneous orders for the last unit, one order processes and the other gets an out-of-stock response rather than both selling the same unit. The specific concurrency model depends on your channel mix and order volume - high-traffic flash sales need different handling than steady B2B ordering - and we define it during discovery based on your actual configuration.

That fear is common and honest. Adoption is where most of these projects actually die. Merchandising teams who never wanted to be developers need an admin that works like the business, not like a database. We build the admin alongside the storefront: product updates that don't require developer involvement, fulfilment workflows that match how your warehouse already works, and order management your team can run on a phone. The system ships when your staff can run a full day on it without help.
