Suppliers are able to refund you on whichever card you used to make the payment (i.e. single purchase even if already used, subscription even if it's paused or cancelled, or physical cards, even if they have been deleted).

Single-use cards which have expired can still receive a refund.

Refunds will appear under the Payments tab on your Spendesk account. There should be a "+" symbol located next to the amount of your purchase.

There's no need to attach an invoice, in fact, a refund automatically gets marked with “the receipt cannot be provided”. If you still would like to add a receipt, attach them yourself in the Payments tab. Account owners and Controllers can attach a receipt in Bookkeep > All Payments.

As soon as the refund has been processed by the merchant, the funds should be transferred back to your company account within a few days or weeks depending on the merchant.
