Referral and viral marketing platform (GrowViral)
- 2.5x
- higher conversion rates for a US marketing agency
Off-the-shelf referral tools work fine until you need reward logic that matches your business model. ReferralCandy and Extole have fixed incentive structures, fixed attribution windows, and fixed fraud rules. None of that was designed for your program.
We build custom referral program software for businesses that need something specific: multi-step reward qualification, white-label campaign experiences, deep integration with your loyalty stack, or fraud detection calibrated to your actual member behavior. The referral engine is built around your program, not the other way around.
Unique link engine with multi-channel attribution, referral code generation, and UTM tracking
Dual-sided reward logic with custom qualification rules, reward types, and payout triggers
Fraud detection built around your actual risk profile, not a generic blocklist
White-label campaign pages and embeddable widgets that look like your product

The problem
Your referral tool caps the reward types you can offer or the attribution windows you can set?
Fraud eating into your referral budget because the off-shelf rules don't match your user pattern?
Short answer
RaftLabs builds custom referral program software with unique-link attribution, dual-sided reward logic, and fraud detection that off-the-shelf tools cannot support. A focused program starts around $25,000-$45,000; a full white-label platform grows toward $90,000. We launch a validated v1 in 10-16 weeks, then iterate from live data. We built GrowViral, a referral SaaS that delivered 2.5x higher conversions for a US marketing agency. Fixed price, full IP ownership.
Key takeaways
Trusted by


That works for a Shopify merchant running a simple 10% discount referral. The problem starts when your program has a different shape.
According to Nielsen's Global Trust in Advertising report, 84% of consumers trust recommendations from people they know over all other forms of advertising. That trust only converts into revenue when the referral mechanics behind the program (attribution windows, reward logic, fraud prevention) are built to match how your customers actually buy.
The economics hold up after the referral, too. A Journal of Marketing study that tracked roughly 10,000 bank customers found referred customers carry a lifetime value at least 16% higher and churn about 18% lower than similar non-referred ones (Schmitt, Skiera and Van den Bulte, 2011). A program only captures that value when attribution credits the right referrer and fraud does not drain the reward budget.
A SaaS product where the real conversion event is a paid subscription, not a free signup. An insurance brand where the referred customer's first policy is the trigger, not their first quote. A loyalty platform where referral credits need to convert into points on the same ledger as everything else. Off-the-shelf referral tools were not built for any of those programs.
RaftLabs builds custom referral program software for businesses where the standard mechanics do not fit. We shipped GrowViral, a white-label SaaS platform that gave a US marketing agency the tools to run referral programs, sweepstakes, and affiliate campaigns for their clients - delivering 2.5x higher conversions across active campaigns. One team handles the attribution logic, reward rules, fraud prevention, and integration layer. The scope is locked and the price is fixed before development starts.
| Model | How it works | Best for | What to watch |
|---|---|---|---|
| Single-sided | Only the referrer earns a reward on a qualifying referral. | Low-margin ecommerce where a double payout breaks the unit economics. | Weaker pull for the referred user, so the invite needs a strong offer of its own. |
| Double-sided | Both referrer and referee earn once the referral qualifies. | SaaS and subscription products where activation, not signup, is the goal. | Higher reward cost per conversion, so the qualifying event has to sit past the free tier. |
| Tiered or milestone | Rewards escalate as a referrer clears set thresholds, or unlock after multi-step actions. | Communities, B2B, and high-LTV products that want repeat referrers, not one-offs. | More qualification logic to track, and more surface area for reward gaming. |
Most programs combine two of these. We map the model to the behavior you want to drive and the reward economics your margins support during the discovery week, before any code is written.
Capabilities
Unique referral URL generation for every participant, each link resolved at click time so the referred user's journey is tracked from first touch to conversion. Multi-channel attribution covers web, mobile app, QR code, and SMS, with configurable windows from 24 hours to 90 days and cross-device tracking handed off via a server-side token, not a cookie.
Dual-sided reward structures where both referrer and referee earn on qualifying conversion, with multi-step qualification for programs where one event is not enough. One rule engine handles discounts, Stripe cash payouts, store credit, loyalty points, and gift cards per campaign without code changes. Hold periods catch charge-backs and trial non-converters before credit releases.
Self-referral detection compares device fingerprint, IP address, and email domain against the referrer's profile, flagging matches for review. Disposable-email and proxy-IP signups go to a review queue instead of earning credit, velocity rules flag referrers whose claim rate spikes, and per-campaign risk scoring auto-approves low-risk events and queues the rest, tuned to your user pattern.
Shareable campaign pages built to your brand, showing each referrer's link, progress tracker, and earned rewards in a mobile-first layout. Embeddable widgets drop into your product with a single script tag and update in real time, so new campaigns launch without developer support. Branded share cards render correctly in WhatsApp, SMS, and email.
Shopify integration via the Storefront API and order-complete webhooks, with referral discounts injected into checkout. WooCommerce, Magento, and custom platforms connect through REST hooks. Salesforce and HubSpot sync referred user data and conversion events, Klaviyo, Braze, and Mailchimp receive referral events as automation triggers, and Stripe handles cash payouts, gift cards, and store credit.
White-label admin dashboard for running referral programs across multiple brands from one login, the model GrowViral was built on: each brand gets independent reward rules, fraud thresholds, and analytics. A no-code campaign builder creates, clones, and pauses campaigns without a deploy, and real-time analytics show the full funnel, referred-user LTV versus organic, and reward cost per acquisition.
How we work
Every referral project follows the same four phases. Scope is locked and price is fixed before development starts.
We map your referral mechanics, attribution requirements, fraud risk profile, and integration points. You leave week 1 with a written scope document and a fixed-price quote. Development does not start until you sign off.
Reward qualification logic, attribution windows, and fraud prevention rules are designed before any code is written. A design decision made in week 2 costs a fraction of the same decision made in week 9. The spec is locked before the build starts.
Working referral engine at a staging URL by end of sprint one. Integrations tested against real transaction flows. QA runs in parallel with every sprint, not as a phase at the end.
Production deployment with monitoring activated on launch day. 8 weeks of post-launch support included in every project. Attribution accuracy and fraud rule performance monitored from day one.
Most referral programs fail for the same handful of reasons. We scope the guardrails in week 1 instead of patching them after the first bad month.
Why us
No handoff after the contract is signed. The people who map your referral mechanics in week 1 are the same people who ship in week 12. What they commit to, they deliver.
We scope the work, calculate the cost, and lock it in writing before any development starts. A scope change is a change request: priced, agreed, or dropped. It never absorbs into the project and appears on the final invoice.
We built GrowViral, a white-label referral SaaS for a US marketing agency. The platform gives agencies a no-code campaign builder, unique URL attribution, dual-sided reward automation, and 12+ integrations. Result: 2.5x higher conversion rates across referral campaigns.
Self-referral detection, device fingerprinting, velocity rules, and reward hold periods are scoped in week 1. Not added after the first fraud incident in month 3. We have seen what happens to referral programs that treat fraud prevention as optional.
What clients say
Three-year average engagement. Founders and operators describing the work in their own words. No marketing varnish.

All of the sprints were completed on schedule and on budget. We highly recommend RaftLabs!

Read moreWe build refer-a-friend programs with unique link or code generation, dual-sided reward structures where both referrer and referee earn, multi-step qualification programs where a reward triggers after the referred user completes a set of actions (first purchase, account activation, subscription upgrade), affiliate and partner programs with tiered commission structures, B2B referral programs for agency and channel partner incentives, and white-label referral SaaS platforms where the referral engine itself is a product you sell to other businesses. Most programs combine several mechanics. The right structure depends on what behavior you want to drive and what reward economics your margins support.
Off-the-shelf referral tools give you their attribution window, their reward types, and their fraud rules. None of that was designed for your specific program. Custom referral software means your attribution logic tracks the signals that matter for your product (not just last-click), your reward structure matches your actual unit economics (not a fixed percentage), your fraud prevention is calibrated to your user pattern (not a generic blocklist), and your campaign pages look like your product rather than a third-party widget. RaftLabs shipped GrowViral, a white-label referral SaaS that delivered 2.5x higher conversions for a US marketing agency. Off-the-shelf tools work for standard programs. Custom is the right answer when standard does not fit.
Referral fraud takes three main forms: self-referral (one person creates two accounts to claim both sides of the reward), fake account creation (bots or farms generate referred signups with no intent to convert), and reward gaming (users who find loopholes in the qualification logic to claim multiple rewards). We build fraud prevention at the attribution layer, not as a bolt-on. That includes device fingerprinting and IP consistency checks on referred signups, velocity rules that flag reward claims above a configurable threshold per user, account age and activity checks before reward release, manual review queues for high-value claims, and reward hold periods that wait for a qualifying post-referral action before credit is issued. The fraud rules are set to match your actual user pattern during the discovery phase, not applied from a generic template.
A focused referral program with a link engine, dual-sided reward logic, and basic CRM integration launches a validated v1 in 10-12 weeks. A full platform with white-label campaign pages, fraud detection, multi-channel attribution, and ecommerce integration launches in 12-16 weeks. That first version is the live slice you validate with real referrers, then iterate from attribution and fraud data. The biggest time variable is integration complexity: a Shopify integration takes two weeks less than a custom ERP integration. We scope the integration map in week 1 and give you a fixed delivery date before development starts.
A focused referral program with link generation, dual-sided rewards, and one CRM integration typically runs $25,000-$45,000. A full platform with white-label campaign pages, fraud detection, multi-channel attribution, and multiple ecommerce integrations typically runs $45,000-$90,000. Projects that include a white-label admin panel for agencies managing multiple brand campaigns sit at the higher end. Cost is set by the complexity of your reward qualification rules, the number of integrations, and whether you need white-label capabilities. We give you a fixed-price quote after a 30-minute discovery call.
Yes. We integrate referral engines with Shopify, WooCommerce, Magento, and custom ecommerce platforms via order-complete webhooks and storefront APIs. CRM integrations with Salesforce and HubSpot sync referred user data, reward status, and conversion events to the customer record so your sales and marketing teams see referral data alongside CRM history. Marketing automation integrations with Klaviyo, Braze, and Mailchimp publish referral events as triggers for automated email and SMS sequences. Payment integrations with Stripe handle cash reward payouts, gift card issuance, and credit balance management. The integration map is scoped in week 1.
