Total cost, not list price

| Decision criteria | PromoteKit | BixGrow |
|---|---|---|
| Consider for | Stripe-based solo founders and small SaaS teams testing a first affiliate program, particularly those wanting coupon tracking and a real but capped free tier. | Small Shopify merchants seeking inexpensive customer referral programs that can graduate from one affiliate to many. |
| Paid entry / monthly | $0/month | $0/month |
| Billing detail | Free plan: $0 with up to three referrals. Pro: $39/month, or $29/month with annual billing; Pro covers up to $10,000 per month of affiliate-attributed revenue. Above that, request an Enterprise quote. | 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 | Yes | Yes |
| Free plan detail | Free plan is limited to the first three referrals and one affiliate campaign; it is not an unlimited free tier. A 14-day paid-plan trial is also advertised. | Free allows ONE affiliate, one affiliate program, and up to 50 referred orders per month. Paid plans advertise a 14-day trial. |
| Commissions | Fixed or percentage rewards can run on one-time purchases or qualifying subscription renewals. Paid tiers support product-specific rules and commission tiers; refunds in Stripe adjust commissions. | Basic affiliate commission rules, with advanced product-specific commission flows on Scale and tier/multilevel incentives on Pro. |
| Tracking method | Tracks links using a website tracking script, or Stripe promo codes without website script; referral cookies default to 60 days and are configurable. Stripe is required for billing attribution. | Referral links, tracked coupon codes, post-purchase referral widget and email-based marketing automation for store customers. |
| Payouts | PayPal and Wise batch exports and manual payouts are offered. Optional one-click Stripe Connect global payouts require a paid plan/trial; current FAQ describes processing fees of 5% for bank funding or 8% for card funding on the payout total. Verify payment coverage and checkout fees before using. | PayPal automatic payouts are reserved for Advanced, while other tiers use supported manual or other methods. Payment provider fees are external. |
| Integrations | Requires a Stripe account. Dedicated Webflow app and integrations with Memberstack, Outseta and MemberSpace are documented. Paddle/Chargebee native billing integrations were not confirmed. | Shopify affiliate and customer referral flows; Paddle Billing SaaS renewal attribution is not documented as native. |
| API available | Yes | Yes |
| Consider the limitation | Merchants who use Paddle instead of Stripe, need more than three referrals without paying, or exceed Pro's $10,000 monthly affiliate-attributed revenue allowance. | Large programs needing unlimited referrals on Free, automated PayPal payouts without Advanced, or direct Stripe SaaS/Paddle subscription tracking. |
