I paid the invoice but e-kyla shows that the invoice has not been paid…?

The status of invoices will be “payable” on the invoice management page until the due date of payment. After the due date the status of an invoice which is unpaid or partly unpaid will be “unpaid” (even if only 0.01 EUR remained due) and the debt column shows the unpaid amount in red. If an invoice is partly paid before the due date, the status will be “payable” until the due date without a reference in the debt column of the invoice register.
