Ecommerce-focused platform that runs both customer referral and affiliate programs from one Shopify install, with post-purchase prompts and fraud protection.

Developer-friendly referral software built for marketing and product teams who want APIs, webhooks, and white-labeled portals without building from scratch.
Read the verdictRewardful
Rewardful starts at $49/month with zero transaction fees and caps affiliate revenue at $7,500 on the Starter plan. The Stripe integration is genuinely native—commissions sync automatically with subscription changes, and you can view affiliate data directly in your Stripe dashboard. Solo founders appreciate the 14-day trial and straightforward setup, though some report slower product updates since the 2024 acquisition by saas.group.
ReferralCandy
ReferralCandy's hybrid pricing—$39/month base plus a 10.5% success fee on the Basic plan—looks affordable until referrals actually work. At $10,000 in monthly referral revenue, you're paying $1,089 total. The platform earns a 4.9/5 rating on Shopify for good reason: automated rewards, two-sided incentives, and seamless integration. But solo founders should model total costs carefully, as the success fee compounds quickly and may justify upgrading to the Grow plan ($79/month + 3.5%) almost immediately.
GrowSurf
GrowSurf pricing starts at $179/month for the Startup plan (up to 10,000 participants) and ranges to $449/month, with a free trial available. It's explicitly not designed for ecommerce—GrowSurf targets tech companies, SaaS, and fintech teams who need event-based rewards, REST API access, and embeddable widgets. Solo technical founders value the implementation speed (many launch in a day) and the clean UI, though the higher entry price suits those with existing customer bases ready to refer.
How we'd actually decide
- If you're a bootstrapped SaaS founder billing through Stripe and want zero transaction fees with straightforward affiliate tracking: Rewardful.
- If you run a Shopify store and can stomach success fees that scale with referral revenue in exchange for post-purchase automation and fraud controls: ReferralCandy.
- If you're a technical founder at a B2B or fintech startup who needs webhooks, API access, and white-labeled portals to match your product experience: GrowSurf.
- If your monthly referral revenue will exceed $15,000 and you need predictable costs without percentage-based fees eating into margins: Rewardful or GrowSurf over ReferralCandy's compounding success fees.
