Error message
Invalid expense account specified.Affected ERP integrations
Exact Online
Cause
This is an internal error that occurs when the Payhawk General G/L account or Fees G/L account, which are configured within Payhawk's Exact Online integration settings, are not found in the Chart of Accounts that Payhawk has pulled from your Exact Online instance.
This situation typically occurs if:
The specific G/L accounts that Payhawk expects to use for general expenses or fees are missing from your Exact Online Chart of Accounts.
The accounts exist in Exact Online but have been incorrectly selected or mapped in Payhawk's integration configuration.
Solution
To resolve this issue:
In the Payhawk Web Portal, go to Settings > Integrations > Exact Online.
Click on its three-dot menu and select Edit configuration.
In the configuration fields for the Payhawk General G/L account and Fees G/L account:
Verify that the accounts currently selected in Payhawk match active and valid G/L accounts in your Exact Online Chart of Accounts. If they do not, update the selections in Payhawk to point to the correct G/L accounts.
Alternatively, you can leave these two account fields empty in Payhawk's configuration. Payhawk will then attempt to automatically create these necessary G/L accounts in Exact Online for you.
Save your updated integration settings in Payhawk.
Attempt to export the expense again. The export must now be successful.
