BixGrow

BixGrow is a Shopify affiliate and referral app positioned against UpPromote on price, and its main argument is flat subscription pricing with no performance fee on referred sales.

The free Starter plan is limited but real: one affiliate, one program, 50 referral orders a month, one coupon per affiliate, plus basic analytics and landing pages. Scale at $19.99 a month opens unlimited affiliates and unlimited programs. Pro at $29.99 adds multi level marketing and tier structures. Advanced at $49.99 brings PayPal payout automation and API access. Annual billing is available on every tier, and all paid plans include email automation and fraud protection.

For a store doing moderate volume the maths is straightforward. A percentage based competitor taking 2 percent of referred sales costs $200 a month once affiliates drive $10,000, while BixGrow stays at its flat rate. The comparison flips if your affiliate revenue is small, since the percentage tools often start cheaper in absolute terms.

It is Shopify only, the app is younger than the established names, and the partner ecosystem around it is thinner. But the pricing is transparent, the free tier lets you test the mechanics properly, and for a store that expects affiliate revenue to grow, avoiding a percentage fee compounds in your favour.
