Total cost, not list price
Platform fee, percent of revenue, payout fees and seat limits are recorded separately, so you can compare what a program really costs.
Documented facts, not a quality ranking. Pricing and rights depend on the selected plan.
| Decision criteria | Refgrow | BixGrow |
|---|---|---|
| Consider for | Bootstrapped SaaS startups needing an embedded portal and Stripe or Paddle subscription attribution at a low entry price, with enough room in the plan's revenue allowance. | Small Shopify merchants seeking inexpensive customer referral programs that can graduate from one affiliate to many. |
| Paid entry / monthly | $29/month | $0/month |
| Billing detail | Starter: $29/month billed monthly, with up to $1,000 in affiliate-generated revenue per month. Annual prices depend on checkout selection. | Free $0/month; Scale $19.99/month, Pro $29.99/month, Advanced $49.99/month on monthly billing. Annual plans are discounted separately. |
| Free plan | No | Yes |
| Free plan detail | No permanent free plan. The live pricing page states a 7-day free trial; card is required and billing starts after the trial unless cancelled. | Free allows ONE affiliate, one affiliate program, and up to 50 referred orders per month. Paid plans advertise a 14-day trial. |
| Commissions | Supports one-time and recurring commission rules, affiliate-level and product-level overrides, and subscription payment events. A cancellation does not automatically reverse commissions from previously paid orders; a related refund event is needed. | Basic affiliate commission rules, with advanced product-specific commission flows on Scale and tier/multilevel incentives on Pro. |
| Tracking method | Embedded widget, referral links, cookies, coupons, fraud controls and webhooks. Paddle requires accurate referral code propagation to custom_data, signed webhook processing and appropriate customer read permissions to match link-driven buyers. | Referral links, tracked coupon codes, post-purchase referral widget and email-based marketing automation for store customers. |
| Payouts | PayPal/Wise auto payouts are a Pro-and-above feature, not Starter. Vendor says there are zero platform transaction fees; external payment providers may charge payout processing fees. | PayPal automatic payouts are reserved for Advanced, while other tiers use supported manual or other methods. Payment provider fees are external. |
| Integrations | Documentation covers Stripe, Paddle webhooks, Polar, Lemon Squeezy and Dodo Payments. Paddle integration needs an API key with customer, transaction and subscription permissions and a webhook; don't treat that as automatic zero-configuration attribution. | Shopify affiliate and customer referral flows; Paddle Billing SaaS renewal attribution is not documented as native. |
| API available | Yes | Yes |
| Consider the limitation | Teams expecting a no-card free trial, an uncapped $29 plan, managed payouts on Starter, or effortless Paddle implementation without required API permissions. | Large programs needing unlimited referrals on Free, automated PayPal payouts without Advanced, or direct Stripe SaaS/Paddle subscription tracking. |
