Once the invoice has been paid, you of course want to mark it as paid in your Vetocare.

To mark an invoice as paid, navigate to the invoice that you want to mark as paid via "Invoices". Then you just have to press the "Mark as paid" button to mark the invoice as paid. 

After an invoice has been marked as paid, a green label will appear on the invoice with "This invoice has been paid".

If you still want to mark an invoice as unpaid, you can press the "Mark as unpaid" button for an invoice with a paid status.

A paid invoice will be displayed in the "overview" as "Paid".
