Refermate

Refermate helps you turn completed purchases into referral sales by giving customers post-purchase reward links they can share. After checkout, shoppers get a store-domain referral link to copy and share with friends or followers. You control the customer reward rate and can review all attributed orders in the embedded app before any rewards are settled. The app tracks clicks and monitors which orders came from referral links, so you only pay for results. Shopify usage billing applies exclusively to approved referred sales, making it easy to manage your referral program costs.
