CA: Conditionally accepted
What it means
Peppol status CA in an Invoice Response means the buyer accepts the invoice under the conditions given in the response and will pay accordingly unless the seller disputes them.
The usual cause
Part of the invoice is not as the buyer expects, most often payment terms such as the due date or bank account not matching the contract.
How to fix it
Read the conditions. If you agree, do nothing; if you do not, object to the buyer outside Peppol before they pay.
