InvoiceUnderPayment(20007014, InvalidData)

Description

The error occurs when the Integration Platform tries to match a payment to an existing invoice in Fortnox. The message means that the payment being sent is lower than the invoice amount, which makes Fortnox consider the invoice underpaid. Therefore, the export is stopped.

Cause

• Incorrect payment amount has been registered in the source system.

• The invoice has already been partially paid in Fortnox, and the export attempts to register another partial payment without matching the remaining balance.

• Differences in currency handling or rounding.

Action

• Check the invoice amount in Fortnox

  • Open the invoice and verify the amount.

• Check the payment in the source system

  • Ensure that the payment amount is correctly registered.

  • Compare the payment with the total invoice amount.

• Handle the underpayment

  • Configure in the Integration Platform that underpayments should be allowed.

  • Pay the invoice manually.
