VAT + VAT registration number on invoices

For European companies it would be helpful if you would list the VAT plus the company VAT number on the invoices.

“Given that these invoices are marketed as “business”, in order to serve European customers (but also for example GST for Singaporeans, GST for Canada, as long as it’s over 30 CAD), it’s required to list VAT/GST (even if it’s 0% or reverse charged), unless it’s ICP (intra-european), for which different rules apply.”

“A US based business selling goods and services to a EU VAT registered business, does not collect VAT on the sales. They are required to indicate the buyer’s VAT registration number on the invoice.”
