Free invoicing tools for businesses in Europe
Five free tools for businesses that invoice across Europe: late payment interest and payment terms under the EU baseline rule, VAT number checks (VIES and HMRC), a Peppol e-invoice validator and an e-invoicing checker for 11 countries. No sign-up.
- Late payment and credit control
Late payment interest calculator
Late payment interest on a business invoice under the EU baseline rule: ECB rate + 8 points (10.40% in late 2026) and €40. Check your national law.
- Late payment and credit control
Payment terms calculator
When is a business invoice late under the EU baseline rule? 30 days after receipt by default, 60 days unless expressly agreed. Check your national law.
- VAT and invoice details
EU VAT number checker
Check any EU VAT number in VIES, the European Commission's system, with the registered name and address when available. UK GB numbers are checked with HMRC.
- E-invoicing
E-invoicing mandate checker
Choose your country and answer a few questions to see which e-invoicing obligations apply to your business, when, and whether each one is law, a plan or a bill.
- E-invoicing
E-invoice validator
Upload a UBL or CII e-invoice: the validator applies the EN 16931 and Peppol BIS Billing 3.0 rules and explains every error in plain English. Free, no sign-up.
Why these tools
Honest about scope: the calculators apply the EU baseline rule of Directive 2011/7/EU and say so. For the UK and Ireland, use our national versions, which apply the national law.
The e-invoicing checker shows the real timeline of 11 countries, and the legal status of every step: in force, law passed, plan, bill or announcement.
Every page lists its official sources (EUR-Lex, ECB, national tax authorities, OpenPeppol) and the date the rules were checked.
