What do you do if a supplier refuses to send invoices via Peppol?

I would like to receive an official answer from Dexxter about this here:

I also received that notification. According to efactuur.belgium.be "In this case, the customer retains the right to vAT deduction based on the invoice issued by alternative means (e.g., in pDF or paper form). If the invoice is issued electronically, the customer must agree to this." https://efactuur.belgium.be/nl/FAQ/general-questions-b2b#Supplier%20not%20ready

I am in a similar situation with two companies that do not send invoices via Peppol. I am now wondering what needs to be done. The other company is not yet okay, but I can no longer recover vAT? How do we resolve this?

Received on Dexxter support:

The government is currently allowing a grace period for the activation of Peppol. This is a temporary exception!

During this grace period, you can still recover vAT for the time being, even if the invoice was not sent via Peppol.

It is important that you can prove that you have made efforts to activate Peppol, or that you have explicitly asked your suppliers to invoice via Peppol from now on.

In Dexxter, you can still edit the "VAT deduction" percentage for the time being (despite the warning during entry). This is set to 0 percent VAT deduction as the standard value, but can be temporarily edited.

Thank you for the information. I fear that the start-up period will create even more uncertainty. Fortunately, it is okay on Dexxter's side.
