Referbro: Referral Marketing

Referbro helps Shopify stores launch and manage referral programs with channel-ready sharing and automated rewards. Merchants can configure reward types, set minimum order values, and validate orders before payouts. The app includes built-in fraud checks for self or duplicate referrals, track performance metrics, and run unlimited campaigns. Setup is fast with theme app embeds and configurable messages. Pricing is flat based on order volume; no per-order commission.
