FAQ

What people ask right before they get blocked

Does a VIES miss prove the company cannot receive invoices?

No. VIES validates VAT evidence, not the whole delivery chain, and it can be temporarily unavailable.

Why compare VAT and enterprise numbers?

Because Belgian teams often mix VAT-based identifiers with the enterprise-number route used in Peppol.
