What to do if you see the message "contra account number is missing for expense"

The cause:

A contra account is missing in Pleo, and so the export to Datev fails.

The solution:

1. Please double-check that you've created contra accounts in Datev for Pleo card (and potentially also Reimbursements) expenses.

2. Copy the contra account number(s) into the setup page in Pleo.
