Do you use the invoicing module? Then please note the following!
From release 5.0 (May 3rd in the acceptance environment, May 10th in the production environment) in order to remain invoice ready, the field ‘billing address country’ will be required for the supplier; freelancer; MSP (unit) and customer (including business unit; work location and work location division). In addition, the ‘payment terms’ field is mandatory for supplier, freelancer and MSP. Both fields will be marked so that it is clear that these fields are mandatory for invoicing. This adjustment is necessary because the rules for links with PEPPOL have been tightened.
Please note: if these fields are not filled in, the corresponding invoices will no longer be created after release 5.0. This also applies if you are not using a PEPPOL integration.
This change won’t take effect for another month, so you still have some time. You can ask the different parties to fill in the missing data themselves or you can do this on their behalf.
