Quick answer
UpPromote and BixGrow both provide Shopify affiliate links, coupon tracking and customer referrals, but their pricing models differ. UpPromote offers a permanent free tier and paid subscriptions with a separate percentage fee on approved successful referral sales. BixGrow also has a free plan, but it limits you to one affiliate and 50 referred orders; paid Scale starts at $19.99 per month with a different feature and payout ladder.

Fixed subscription versus performance fees
On UpPromote Growth, the public fee is $29.99 monthly plus 2% of approved successful referral sales. Professional is $89.99 plus 1.5%, and Enterprise is $199.99 plus 1%. On BixGrow, Scale is advertised at $19.99 monthly, Pro at $29.99 and Advanced at $49.99. The vendors use different feature limits, so the cheapest subscription is not automatically the cheapest equivalent configuration.
Illustrative calculation: suppose a store has $2,000 of eligible approved affiliate sales during a month. UpPromote Growth's software bill would be $29.99 + (2% × $2,000) = $69.99, excluding commissions you pay affiliates and other gateway fees. BixGrow Scale's base subscription is $19.99, but this example is not an identical-feature quote or a guarantee that all referral rules are equivalent.
Free plans: what the limits actually mean
UpPromote's free tier has one affiliate program and a published monthly referral-review allowance. BixGrow's free offering is particularly restrictive: one affiliate, one program and 50 referred orders per month. A store trying to onboard five creators would already exceed BixGrow Free's affiliate count and need to assess a paid plan.
Test the coupon and checkout attribution flow before claiming a free program can support a full ambassador team. Shopify plans, subscription products, storefront changes and promotional discount behavior may affect implementation.
Coupons, customer referrals and commission tiers
Both provide affiliate tracking links and customer referral features. UpPromote's paid tiers expand program count, coupons and commission sophistication, with marketplace/customer referral features on Growth and more powerful automatic coupon creation, bonuses and multi-level options on Professional.
BixGrow Scale unlocks unlimited affiliates, programs and referral orders, while Pro adds additional commission tiers, bonuses and multi-level capabilities. BixGrow Advanced is the vendor-listed tier for API access and automated PayPal payouts. Assess these real feature requirements before deciding using only a monthly headline.
Payout automation, refunds and attribution
UpPromote's automatic PayPal payouts require Professional or above per the current pricing table. BixGrow similarly gates PayPal automation to Advanced. Merchant payment-provider charges are separate from software charges. A refund or cancellation should be tested end to end: verify the referral commission status and, for UpPromote, whether the platform success fee is adjusted under the vendor's stated rules.
Before launch, run a test order from a referral link, a coupon-only order, a repeat-customer order, a refunded order and an excluded-product order. Record who receives commission in each case.
Which Shopify store should choose which?
Shortlist UpPromote if your store needs its referral marketplace, affiliate management workflows or broad professional features, and you can accept a sales-based platform fee. Shortlist BixGrow if predictable low monthly subscription costs, a compact affiliate app and upgrading from a very small free pilot are the priorities.
