Do I charge VAT to a client in another EU country?

For B2B services with a valid VAT-registered client, you generally do not charge VAT — the reverse charge mechanism applies. You must verify the client's VAT number on VIES and add a reverse-charge note to the invoice.

What about clients outside the EU?

Services to clients established outside the EU are usually outside the scope of EU VAT, so no VAT is added. Keep evidence (address, registration) showing the client is non-EU.

Which currency should I invoice in?

You can use any currency you and the client agree on, but most EU countries require you to also show the VAT amount in your local currency, converted at the official exchange rate of the invoice date.

What is the reverse charge note I should include?

A common version is: "Reverse charge — Article 196 of Council Directive 2006/112/EC". This is mandatory for EU B2B intra-community services.

How long do I need to keep international invoices?

Most EU member states require you to retain invoices (issued and received) for at least 6 years, with some countries requiring longer. Keep both the PDF and the underlying data.

Should I use SEPA or SWIFT?

SEPA is faster and nearly free for EUR transfers within the SEPA zone. SWIFT is needed outside SEPA and is slower and more expensive. For multi-currency low-cost transfers, services like Wise are popular.
