Supplier refund receipts
This article explains that within ExpensePlus, you can choose whether receipts for supplier refunds are 'required' or 'optional'.
Settings for receipts for supplier refunds
If set to 'required', then all supplier refunds that are entered (whether via the purchases screen, or via the match transactions screen) will be shown within the receipts screen as awaiting a receipt, until a receipt is either provided or is marked as lost and then authorised as lost.
If set to 'optional', then all supplier refunds won't require a receipt, however, one can still be added.
How to edit the setting for supplier refund receipts
To change the settings for supplier refund receipts, go to Receipts Settings.
Click the 'edit' (pencil) button to the right.

In the popup, change the setting under the title 'Supplier refund Receipts' and click 'submit'.
