If you are a selling to a Business you need to obtain and show your customer's VAT number (including the two-letter country prefix) and your own VAT number on your VAT sales invoice. Additionally check your customer’s VAT number in the VIES database, as this should be contained in the VIES search engine, because it reflects if the company is registered for Intra-EU transactions. 

B2B sales fall under the reverse-charge mechanism, which means that you as a seller are not liable to pay VAT. We will show you how to issue a compliant B2B invoice in a few steps in the next paragraphs.

Issuing Invoices for B2B transaction in Europe is almost the same as for B2C transaction, only differences being your cutomer's VAT number and the 0 VAT rate, which need to be explicitly stated on the invoice. One important matter is your customer's VAT number which needs to be registered in the VIES search engine. 

NOTE: Keep in mind VIES is a search engine not a database. Data is retrieved from relevant national databases.

If your customer is a business in one of the EU member, you should follow the next steps below in order to have a compliant issue:
