Picking a referral platform usually comes down to three names: ReferralCandy, Friendbuy, and Referral Rock. All three help brands turn happy customers into a word-of-mouth acquisition channel, but they price, integrate, and target customers very differently, and those differences matter more than any feature checklist once you look at real monthly costs and who each platform is actually built to serve.
This guide breaks down how each platform charges, what you can connect them to (including their APIs), which one wins for DTC brands versus service businesses, and how their market position and reviews compare, so you can match the platform to your store’s size, stack, and how hands-on you want your referral program to be.
Quick Answer
ReferralCandy is the best fit for small to mid-size Shopify and WooCommerce stores that want a fast, self-serve setup and are comfortable paying a success fee on referred sales. Friendbuy suits mid-market and enterprise DTC brands that want a flat, no-success-fee price, deeper A/B testing, and custom integrations, but pricing is quote-based. Referral Rock is the strongest choice for service businesses, B2B companies, or brands running automated, hands-off referral and advocate programs beyond simple ecommerce discount codes, thanks to its flat monthly fee, no per-sale cut, and 50+ native integrations.
How Each Platform Prices Itself
ReferralCandy runs a tiered model: Basic at $39/month plus a 10.5% success fee, Grow at $79/month plus 3.5%, Scale at $249/month plus 1.5%, and Enterprise at $799/month plus 0.25%. Every tier includes the same core features — unlimited campaigns, custom coupon codes, cash or store-credit payouts, and integrations with tools like Klaviyo — so moving up a plan mainly buys a lower success fee rather than new functionality. The fee only applies to net-new customers a referral program brings in, charged on each new customer’s first three orders, and there’s a 7-day free trial with no fees on trial sales.
Friendbuy does not publish a public pricing page. It sells through custom, quote-based contracts, typically billed annually, with cost driven by your traffic and order volume, whether you add its loyalty module, integration depth, and onboarding needs. The tradeoff for the opacity is that Friendbuy does not charge a success fee on top of the subscription, which can make it cheaper at high sales volume even if the sticker price is higher up front.
Referral Rock uses a single published plan: the Operator Plan at $250/month (roughly 10% cheaper if paid annually), which includes unlimited referrals with no referral caps or overage fees, a dedicated program advisor, hosted referral portals and landing pages, link/code/QR sharing, automated email invites, ecommerce and billing integrations, 10 user and 10 recruiter seats, and custom branding. There’s no setup fee and no success fee — extra member capacity, additional programs, or extra seats are available as add-ons, and Enterprise/multi-location pricing is handled separately.
Integration and API Options: What You Can Actually Connect
ReferralCandy has the deepest out-of-the-box ecommerce integration: it’s a one-click install from the Shopify App Store, and it also connects to WooCommerce, BigCommerce, and Magento, plus email/SMS tools like Klaviyo. Its REST API exposes the core entities you’d expect — customers, referrals, rewards, and orders — so developers can sync referral events into a custom storefront or data warehouse without relying on the pre-built app.
Friendbuy is built API-first: its Merchant API and event-tracking SDK work around a small set of core entities — campaigns (the widget/offer configuration), advocates (referrers) and friends (referees), personal referral links, and rewards — which makes it a strong fit for teams that want to trigger referral moments from custom checkout flows, mobile apps, or a headless storefront rather than a plug-and-play widget. It also integrates natively with Klaviyo and major ecommerce platforms for teams that don’t need custom development.
Referral Rock leans on breadth over API depth for most users: 50+ native integrations spanning CRM, email marketing, ecommerce, forms, payments, and marketing automation, plus a Zapier integration (available on any plan) that connects to thousands of apps for triggers like new referrals, new members, or new rewards. A native REST API and JavaScript snippet are available for teams that want custom development, but most Referral Rock customers get by on the point-and-click integrations alone. Note that other advocate/affiliate-hybrid platforms in this space, such as Ambassador, use a similar entity model (advocates, referral links, rewards) but target larger partner-marketing programs rather than the ecommerce-first use case these three platforms serve.
Which One Fits Your Business
If you run a smaller Shopify or WooCommerce store and want to launch quickly without a sales call, ReferralCandy’s self-serve signup and low entry price make it the easiest on-ramp — just budget for the success fee as sales grow, since it scales with revenue rather than staying fixed.
For DTC brands specifically, the choice usually comes down to volume and control. Friendbuy is generally the better fit once you’re doing enough referral-driven revenue that a percentage-based fee would get expensive, and its stronger A/B testing and branded-experience customization suit DTC teams optimizing conversion rate on the referral widget itself. ReferralCandy remains the better fit for smaller or newer DTC brands that want to launch fast and don’t yet have the volume to justify a quote-based contract.
If your referral program isn’t just about post-purchase discount codes — for example, you’re running partner, affiliate, or B2B customer referral programs, want a full member portal, or need the program to run largely on autopilot once it’s set up — Referral Rock’s flat monthly rate, automated email invites, and program-advisor support tend to be worth the higher entry price compared to ReferralCandy’s per-sale model.
Market Position: Who Actually Uses Each Platform
These three platforms serve different points on the market. ReferralCandy has by far the largest customer base, with tens of thousands of active merchants, mostly small-business Shopify and WooCommerce stores; on G2 it holds roughly a 4.5-star rating with reviewers concentrated in the small-business segment, and reviewers frequently cite ease of use as its strength.
Friendbuy has a smaller, more premium footprint concentrated in mid-market and enterprise DTC brands; its G2 reviews skew mid-market, and reviewers tend to highlight product fit for growing programs and ongoing account support over raw simplicity. Referral Rock sits in between on customer count but leans heavily on B2B, service-business, and membership-style referral programs rather than pure ecommerce discount codes, and its G2 reviews consistently praise ease of use and responsive support, with an occasional learning curve on advanced automation features. In short: ReferralCandy wins on adoption and simplicity, Friendbuy wins on DTC/enterprise depth, and Referral Rock wins on program flexibility outside pure ecommerce.
Best Platforms for Automated, Hands-Off Referral Programs
If “automated” means the program runs itself once it’s live — auto-sending referral invites after purchase, auto-issuing rewards, and syncing to your CRM or email tool without manual work — all three platforms qualify, but they automate different pieces. ReferralCandy automates the ecommerce loop tightly: post-purchase invite, coupon generation, and payout, with minimal setup on Shopify or WooCommerce. Friendbuy automates event-based triggers (signup, purchase, milestone) across a wider set of channels, which suits brands with more complex customer journeys. Referral Rock automates the widest range of non-ecommerce triggers — new member signups, CRM updates, recruiter actions — via its Zapier connection and native integrations, which is why it’s the default pick for B2B and service businesses that want the referral program to run largely unattended.
Tips and Common Mistakes
Don’t compare sticker prices alone. ReferralCandy’s cheapest plan looks like the lowest cost, but its 10.5% success fee on Basic can quickly outpace Referral Rock’s flat fee once your referral program starts generating meaningful sales — model your expected referred revenue before committing.
Ask every vendor, including Friendbuy, exactly what counts toward their fee or contract minimums (new customers only, all orders, a set order count) since these definitions change the real cost significantly.
Don’t skip the trial or demo. ReferralCandy offers a 7-day free trial, and both Friendbuy and Referral Rock will walk through a demo — use that time to check the checkout integration and, if you need custom development, test the API against your own entities (customers, campaigns, referrals, rewards) before signing an annual contract.
Factor in reward costs separately. All three platforms charge for the software itself, but the cash, store credit, or discounts you give referrers and their friends come out of your budget on top of any platform fee.
referral marketing platform comparison FAQs
What are the best referral marketing platforms?
For most brands the shortlist is ReferralCandy, Friendbuy, and Referral Rock. ReferralCandy wins on fast, self-serve ecommerce setup; Friendbuy wins on DTC/enterprise customization and flat no-success-fee pricing; Referral Rock wins on flexibility for B2B, service, and membership-style referral programs.
What are the best referral program software tools for ecommerce brands?
ReferralCandy and Friendbuy are the two most ecommerce-focused options here: ReferralCandy for smaller Shopify/WooCommerce stores that want quick, self-serve setup, and Friendbuy for larger DTC brands that want deeper customization, A/B testing, and flat pricing once referral-driven revenue is significant.
What are the best platforms for automated referral programs?
All three automate the core loop, but they differ in scope. ReferralCandy automates the ecommerce post-purchase invite-to-reward loop with the least setup. Referral Rock automates the broadest range of non-ecommerce triggers through its native integrations and Zapier connection, making it the strongest pick when you want a program that runs largely hands-off outside a simple online store.
Friendbuy or ReferralCandy for DTC brands?
Friendbuy tends to fit larger, established DTC brands better once referral-driven sales volume is high enough that a flat, no-success-fee contract beats a percentage-based fee, and its A/B testing suits teams actively optimizing the referral widget. ReferralCandy fits newer or smaller DTC brands that want to launch fast without a sales process.
What integration options do Friendbuy and ReferralCandy offer?
ReferralCandy has the deepest native ecommerce integration, including a one-click Shopify App Store install plus WooCommerce, BigCommerce, and Magento support, alongside a REST API for custom setups. Friendbuy is API-first, built around campaigns, advocates, friends, and rewards as core entities, and integrates natively with Klaviyo and major ecommerce platforms as well as custom storefronts and mobile apps.
How does ReferralCandy’s market share compare to Friendbuy’s?
ReferralCandy has a much larger customer base, with tens of thousands of merchants (mostly small-business Shopify and WooCommerce stores), while Friendbuy serves a smaller, more premium set of mid-market and enterprise DTC brands. ReferralCandy leads on adoption and G2 review volume; Friendbuy’s reviews skew toward larger accounts.
Does ReferralCandy charge a success fee on every plan?
Yes. Every ReferralCandy plan, including Enterprise, charges a success fee on top of the monthly price, ranging from 10.5% on Basic down to 0.25% on Enterprise, applied only to a new customer’s first three orders.
Is Friendbuy cheaper than ReferralCandy?
It depends on your sales volume. Friendbuy uses flat, custom-quoted pricing with no success fee, so at high referral-driven revenue it can end up cheaper than ReferralCandy’s percentage-based model, but its entry cost and contract terms are usually higher than ReferralCandy’s Basic or Grow plans.
Does Referral Rock charge a setup fee?
No. Referral Rock’s Operator Plan at $250/month includes onboarding and a dedicated program advisor with no separate setup fee, and there’s no success fee on referred sales.
Which platform is best for a small Shopify store just starting a referral program?
ReferralCandy is generally the easiest starting point for small stores because of its low monthly entry price, self-serve setup, and one-click Shopify App Store install — just plan for the success fee to grow alongside your referral sales.
