Using the Payment Checklist
The payment checklist is located in the top right hand corner of the Payment screen. It helps you to complete your payment request. If there is an issue with some part of your payment request, a red X will indicate where the issue is. If a red X is present on the checklist, payment submission is not possible. The checklist is dynamic, so when the issue has been resolved, the red X changes to a green tick mark.
When you first open a payment request, the checklist looks like this:
Before you submit a payment request, verify that the checklist does not indicate that there are any issues with your payment request. It should look something like this:
Note
Not all fields on the payment page are mandatory, so you do not necessarily need a green tick beside every item. But you must ensure that there are no red X marks. Otherwise, submission will fail.
