We would like Mews to automatically generate and display country-specific payment reference numbers on invoices to support payment reconciliation.

Requested functionality:

Sweden: Swedish OCR reference number, preferably based on the invoice number, with a Modulus 10 (Luhn) check digit.

Finland: Finnish domestic reference number (viitenumero), using the standard 7-3-1 check digit calculation.

References should appear on invoice PDFs and be included in invoice exports/API data to enable automated matching of incoming bank transfers.

Business benefit:

This would significantly reduce manual reconciliation, save time, minimize errors and improve the accuracy of matching incoming payments to outstanding invoices.

As a multi-property operator in Sweden and Finland, we believe this functionality would benefit many Mews customers operating in the Nordic markets.
