Getting your invoice rejected because of a missing field is frustrating — and it happens more often than you think. EU Council Directive 2006/112/EC and UK HMRC Notice 700 require specific fields on VAT invoices: dual VAT registration numbers, per-line tax rate selectors, and a Reverse Charge disclaimer for cross-border B2B sales. Miss any of these, and the invoice can be legally void. I have seen this happen to a freelance developer based in Berlin who billed a client in Amsterdam. He forgot to include his VAT number, and the client's tax auditor flagged the entire expense. He had to reissue the invoice, and payment was delayed by six weeks.
In our experience, the most commonly overlooked detail is the VAT registration number format. Each EU member state follows a distinct pattern: France uses FR followed by 11 characters, Germany uses DE followed by 9 digits, and the UK uses GB followed by 9 or 12 digits. Entering the wrong format can cause the invoice to fail automated validation checks inside your client's accounting system. We do not auto-validate the format yet, so we recommend checking the buyer's VAT number on the VIES database before you issue the invoice. For cross-border transactions, the Reverse Charge mechanism shifts the VAT liability to the buyer. Make sure the invoice clearly states "Reverse Charge: VAT shifted to the buyer" and that you include the buyer's VAT number, not just your own. One user told us that adding this single line of text reduced their invoice rejections from four per quarter to zero.
