A VAT invoice is the document that turns the work you just finished into taxable income the tax office will recognise. For a freelancer it is never just a bill: it proves the sale took place, tells your client exactly how much input tax they can reclaim, and protects you if your books are ever audited. Most independents treat the invoice as a final formality, but it is also your strongest record if a client later questions the work or a year-end review comes around. Get the layout right the first time and every invoice after it gets faster.
What to include
A VAT invoice has to carry a handful of mandatory details or it can be thrown out for tax purposes. Put your own VAT number on it, and for business customers theirs as well. Add a sequential invoice number, the tax-point (issue) date, and a clear description of the goods or services. If you sell to consumers, their VAT number is not required, but your own name, address and the invoice currency should still be stated plainly. Leave any of these out and the document is harder to enforce — and in a VAT dispute it may not count at all.
How the VAT is calculated
You must show VAT separately on every single line and then state the total VAT at the bottom. The rate applied here is 19%. The whole point of the invoice is to let your client recover that input tax, so the maths needs to be obvious: net amount × 19% gives the VAT, and net plus VAT gives the total. When you bill a business customer in another EU country, the reverse-charge rule usually takes over — you charge 0% and print both VAT numbers. Check which rule applies before you lock in the total, and if you ever apply the wrong rate, issue a credit note and re-invoice rather than scribbling a fix on the PDF.

Thank you for your business. Payment due within 14 days. Late payments may incur a fee.
Example preview — not a real invoice
A real VAT invoice reads like a short, honest breakdown rather than a mystery total:
- Consulting services — 10 hours × $120 = $1,200
- Software licence — 1 × $299 = $299
Always show the quantity, unit price and the VAT per line so the grand total is easy to check. Reference any purchase order the client gave you in the description so the charge is unambiguous.
Practical tips
Quote both VAT numbers on any cross-border B2B invoice. Apply the right rate to each item — mixed supplies with different rates have to be split out. Keep every issued invoice for at least 10 years inside the EU; that retention period is not optional. Set a clear due date (14 days is common) and state your payment method on the document. Tidy habits like consistent numbering, clear payment terms and same-day delivery do the rest, cutting late payments and building the trust that brings clients back. If you would rather not build the document by hand, the invoice generator works out the tax maths for you.
Think of the VAT invoice as the final step of the job, not paperwork you do later. A correct, clean document closes the loop on work you have already delivered.
