If the invoice is not paid after the due date, a payment reminder is sent 10 days after the due date, if the invoice is not paid after that, a collection demand is also sent 10 days after the payment reminder. A payment reminder entails a late fee of SEK 60 and a debt collection claim entails an additional late fee of SEK 180. The late fees are added to the next invoice if you do not choose to pay the full amount immediately.
