On Finom you can always keep track of ipayments just selecting the invoice you want and clicking on the button "Mark as paid" on the right side of your screen.
When clicking on the button, a new window will appear and it will ask you the details of the payment
By confirming the payment, your invoice will be moved in the dashboard from the "Sent" section to the "Paid"
In case you received just a part of the payment, you can fulfill the box with the amount paid and the system will record the amount that is still missing, keeping the invoices in the section "Awaiting payment"
