It can happen that you've accidentally uploaded a receipt as a purchase invoice. If that's the case, you can easily move the receipt to the receipts section. However, this is only possible if the document hasn’t been processed yet.
To move a document from purchase invoices to receipts follow the steps below:
Navigate to Expenses in the left-hand menu;
Choose Purchase invoices;
Select the documents you want to move;
Click on Select action and choose Move;
In the pop-up choose in the Action dropdown for Move to receipts;
The document(s) has now been moved to the Receipts.
