Every referral bonus you pay in cash leaves your business and never comes back.
Store credit became a first-class object on Shopify and has worked at POS since summer 2025. That change turns credit from a returns cleanup tool into a currency you issue. ThredUp built a whole trade-in loop on the same logic: send in clothes, get paid in credit, spend it back in the store.
Look at what you currently buy with cash or discount codes. Referrals. Reviews. Photo and video submissions. Survey completions. Trade-ins. Warranty goodwill. Every one of those is a payout, and every payout in cash is a relationship you settled and closed. Pay in credit and the same event opens a return visit instead.
Operationally it is a Flow automation per qualifying event. A review lands, credit issues. A trade-in arrives at the warehouse, credit issues. A support agent resolves a complaint, credit issues at a capped amount, with no discount code that leaks to a coupon site an hour later. Because it is native, the balance follows the customer to the register, which matters if you have stores. Nobody has to remember anything.
The catch is that credit is a liability, not a marketing expense, and your finance lead will say so first. You are booking a promise to deliver goods later. Breakage flatters the math and damages the relationship, so decide deliberately rather than defaulting. Check expiry rules in every market you sell in, because some jurisdictions restrict them and treat unused balances as unclaimed property. Model your redemption rate before you get generous. Credit is also weaker than cash exactly where cash is the point: a customer trading in a coat to fund a different brand's coat will not take your currency, and that is useful information about how strong the brand really is.
A discount ends the transaction. A currency you issue decides where the next one starts.
