Fortnox error: 2000798

Description

Posting of the invoice was stopped because a VAT code is missing a default output VAT account in Fortnox. To post an invoice, every VAT code used must be linked to a sales VAT account.

(The message about the customer being searched/created is informational; the main error concerns the VAT settings.)

Cause

• The VAT code has no linked output VAT account in Fortnox.

• The specified VAT account does not exist in the chart of accounts, is inactive, or is not valid for the current accounting period.

Resolution

In Fortnox, go to Settings → Accounting → VAT codes (or Default accounts) and:

• Link an output VAT account (typically a 26xx account) to the VAT code.

• Ensure the account exists in the chart of accounts and is active for the current period.
