Credit tops up
Offer credit above cash value — it still costs you less than paid acquisition.
Recommerce / Trade-in
Take it back for store credit.
Buy your own product back from customers — pay them in store credit, grade it, and resell it on your storefront. The credit comes back as a second order.
Why store credit
A payout that comes home.
Cash leaves your business. Store credit brings the customer back to the till. Trade-in turns a return into your next sale — and you keep the margin on the resale too.
Stays on-brand
Credit can only be spent with you, so the payout funds a second order.
Repeat intent
Trade-in customers return to spend, lifting repeat-purchase rate.
