If you're outside the EU and billing a business inside it, the question that stalls your first invoice is VAT: do you charge it, and what does the client's finance team expect to see? For business-to-business services there's a common structural pattern — the reverse charge — and once your invoice reflects it, EU clients process you like any local supplier. Here's the shape of it.
The reverse-charge pattern, in plain terms
For many cross-border B2B services, VAT is handled by the buyer, not the seller. Instead of you charging VAT and paying it to a tax authority you have no relationship with, the EU business client accounts for VAT on the purchase themselves through their own return — charging and deducting it in one motion. That mechanism is called the reverse charge, and it's why a well-formed invoice from a non-EU supplier to an EU business typically shows no VAT amount at all. The European Commission's place of taxation overview explains where B2B services are taxed and why the buyer accounts for the VAT.
This is the common case, not a universal law. It generally holds for services supplied to a VAT-registered business, and it can work differently for consumers, for digital products sold to individuals, for services tied to specific places (property, events), and in other situations with their own rules. If your work fits the ordinary "professional services to a business client" mold, the reverse-charge pattern is what your client's finance team will expect; if it doesn't, that's the moment to confirm the treatment properly.
What your invoice needs
Three things distinguish a reverse-charge-ready invoice from a domestic one:
- The client's VAT number. EU businesses have a VAT identification number (country prefix plus digits — DE, FR, NL, and so on). Ask for it and print it with the client's details: it's what evidences that your client is a business, which is the hinge the whole treatment swings on. Your client can be validated in the EU's official VIES VAT number validation system, and their accountants will do exactly that with your invoice in hand.
- No VAT charged, visibly. Either omit the tax line or show VAT at 0% — and pair it with the note below so the zero reads as deliberate, not forgotten.
- A reverse-charge note. One sentence tells the client's bookkeeper how to file you: "VAT reverse charge — VAT to be accounted for by the recipient." Wording along those lines is widely used; some businesses ask for a specific formula, and it costs nothing to use theirs.
Everything else is standard international practice: both parties' full legal names and addresses including countries, an unambiguous currency (EUR is the natural choice for EU clients — see which currency to invoice in), and payment instructions with sender-covers-fees wording.
A complete example
Example: US consultant invoicing a German company, reverse charge
The client's German VAT number sits with their details, VAT shows 0% with an explicit reverse-charge note, and amounts are in EUR with wire terms.
When the pattern doesn't apply
Two situations to recognize rather than solve on your own: consumers (B2C sales, especially of digital services, can put registration and collection obligations on you, even as a non-EU seller), and your own country's export treatment (whether your home tax system wants anything shown on export invoices is a separate question from EU VAT). Both are worth one conversation with an accountant if they describe your business — and neither changes the B2B invoice format above.
Set the template once
An EU-ready invoice is a normal invoice plus a VAT number field and one note. The free VAT invoice generator handles it directly: tax ID fields on both parties, a VAT label at any rate including 0%, EUR among its 25+ currencies, and a notes field for the reverse-charge line — free, no signup, no watermark. For the broader fundamentals, start with invoicing international clients.
Tax rules vary and change — confirm the specifics with your accountant or local tax authority.
