VAT Registration Proof Required Before Payment Email Template

Use this page when the buyer says invoice payment is on hold until the supplier provides VAT registration proof or tax-identification evidence. This is not a generic supplier-onboarding follow-up. The commercial problem is that the invoice is otherwise moving, but AP or tax compliance will not release it until the supplier's VAT identity is documented to the buyer's standard. Your email should ask exactly what proof is missing, whether the VAT registration must match the invoicing entity, whether the hold affects only this invoice or future payments as well, and what timing applies once the document is submitted. The outcome you want is to turn a broad request for VAT evidence into a named documentary step with a direct path back to payable status. It is commercially strong because the supplier is often already entitled to payment, but tax-validation friction is still keeping the cash from being released.
