Cash back

What is cash back?

Cash back is a rewards incentive where a customer earns back a portion of the money they spend on a purchase, usually as a percentage like 1%, 5%, or in some programs higher. The earned amount can typically be applied to future purchases, transferred as cash, or credited to the customer’s account or store wallet.

Cash back is most commonly associated with credit cards, but in ecommerce it functions as a loyalty program reward where shoppers earn back a slice of every order to redeem on later purchases. For Shopify and DTC brands, it’s one of the more direct levers for customer retention, since it gives shoppers a financial reason to come back rather than buy the same product from a competitor.

How does cash back work in ecommerce?

A typical ecommerce cash back flow looks like this:

• A shopper buys a product or service from a store that offers cash back as a reward.
• The store, or a partner like a rewards app or credit card issuer, allocates a percentage of the purchase amount, usually between 1% and 10% in ecommerce, to give back to the buyer.
• The transaction is recorded and the cash back amount is calculated based on the eligible total (often excluding shipping and taxes).
• After a set period, often once the return window has passed, the cash back is credited to the customer’s wallet, store credit, or account balance.
• Once enough cash back is accumulated, the shopper can apply it to future purchases, convert it to a gift card, or withdraw it depending on the program’s rules.

Cash back programs come in a few common formats: flat-rate (the same percentage on every purchase), tiered (higher rates on specific product categories), or stacked alongside other subscription savings like subscribe-and-save discounts.

It’s a win-win situation where customers save money, and stores drive loyalty

Example of cash back

A Shopify merchant offers a cash back deal: “Get 5% back on every subscription order.” A customer who spends $50 monthly on a coffee subscription earns $2.50 in rewards each cycle. Over a year, that adds up to $30 in store credit, which compounds the value of staying subscribed and gives the shopper a concrete reason to keep their subscription active instead of switching brands.

Cash back works especially well on recurring subscriptions, since the rewards compound with every cycle. Test different cash back percentages and redemption rules to find the level that drives repeat purchases without eating too far into margins.
