What to do if you see the message "There is no open accounting year for date..." or "Missing accounting year ... "

The cause:

If the date of any of your Pleo expenses are dated outside of the open accounting year (in e-conomic), the export will fail.

The solution:

Please follow this link to add the new accounting year in e-conomic: https://secure.e-conomic.com/settings/finance/accounting-years. Once added, the export from Pleo should work properly.
