Invoice in any currency. Get paid without the compliance headache.
Bill your clients in EUR, GBP, USD, or any currency they prefer — with invoices that automatically include the right VAT fields, reverse charge notation, and mandatory fields for their country. No manual research. No rejected invoices.
Why generic invoicing tools fail international freelancers
You landed a client in Germany. Or France. Or the Netherlands. You open your invoicing tool, set the currency to EUR, and send the invoice.
Their accountant sends it back.
Why? Because billing in the right currency is only half the job. A German client needs a Leistungsdatum on the invoice. A Dutch client needs your BTW-ID — not your OB-nummer. A French client needs a SIRET number, a specific TVA exemption phrase, and a late payment clause. A cross-border EU invoice needs the reverse charge notation with the exact Article 196 wording.
Generic invoicing tools let you change the currency. They do not know what else needs to change.
Invoicemonk does.
Three steps to a compliant multi-currency invoice
Select your client's country and currency
Choose where your client is based and what currency they pay in — EUR, GBP, USD, CHF, CAD, AUD, KES, PHP, or any currency you agree with your client.
The right compliance fields appear automatically
Invoicemonk knows what each country requires. German client? The Leistungsdatum field appears. Dutch client? BTW-ID and KVK number fields. French client? SIRET, TVA status, and the late payment clause. Polish client? NIP number and KSeF-ready fields. You fill in the details — Invoicemonk handles the structure.
Send a compliant invoice in any currency
Your invoice goes out in the client's currency, with the correct mandatory fields for their country and the correct VAT treatment for your situation. No rejected invoices. No follow-up emails from their accountant.

What compliance-first invoicing actually means
Sequential numbering — enforced
Gaps in invoice numbers are an audit red flag in Germany, Bulgaria, France, and across the EU. Invoicemonk makes gaps structurally impossible — the sequence is enforced by the system, not by your memory.
Reverse charge — automatic
When you invoice a VAT-registered EU business client from outside their country, the reverse charge notation and Article 196 wording appear on the invoice automatically. No manual research. No risk of sending the wrong wording.
Country-specific fields — built in
Every country has mandatory invoice fields that generic tools ignore. Invoicemonk builds them in by default — so your invoice is compliant the first time, not after the accountant sends it back.
