If the invoices are not automatically marked as paid, please check the following:
- Has the customer ordered an electronic bank statement from the bank that marks the payments as completed?
(in machine-readable format so that the details of the transactions are visible on the statement.) - Are the default document type selections for payments missing from the settings?
- Have the accounting accounts that are used/suggested for entries such as accounts payable, value-added tax, and payments been defined in the Settings – General – Accounts tab?
