If the merchant won't give you a receipt, if your pending transaction was cancelled or if you lost it, you still need to report it in Spendesk.
To do so, click on grey button next to "Upload a receipt" on your payment (Payments tab).
You can also use it in the case of a refund.

Continue with the steps and fill in the required information, validate.
Congrats! Your finance team now has a legal document available proving that there was an issue to get a receipt.
