Credit Voucher

Give a customer credit to spend later instead of money back.

What is this?

A credit voucher is store credit you hand out instead of paying a customer back. The till creates it when you settle a return with this method, and the customer spends it on a later purchase. At the till it is called Store credit.

Unlike a gift card, a voucher is never bought. It exists only because you issued one.

How does it work?

Issuing. On a return, choose the method. There is nothing to type in — Flow Retail creates a voucher for the amount owed and puts its number and valid-to date on the receipt.

Redeeming. On a sale, choose the method and fill in Store credit number. The till looks it up, shows the balance, and fills the amount with whichever is smaller — the balance or what is left to pay. A voucher that has expired, is no longer active, or does not cover the amount entered is refused.

Vouchers and gift cards share that system, but they are kept apart. A credit voucher cannot be spent as a gift card, and a gift card cannot be spent as a credit voucher — even after store credit is switched off, because the vouchers already out there still exist.

How do we get started?

Credit vouchers run on the Flow Gift Card system, so that extension has to be active before the payment method is offered at all.

On top of that, vouchers need their own account. Add store credit to each store on the store's Extensions tab and fill in Store Credit Merchant ID, Store Credit Merchant Token and Store Credit Brand ID. The brand is what separates vouchers from gift cards.

Then add the payment method under Admin → Settings → Payment Methods, and set it Active on every store that should issue or accept vouchers.
