About this tool
Europe is switching to structured e-invoicing country by country, each on its own schedule: Belgium since January 2026, France from September 2026, Germany in stages through 2028, Poland via KSeF in 2026. For a business selling across borders, the practical question is not the legal fine print but: does MY customer already require this?
This checker answers exactly that, from the same country table we keep up to date in our timeline guide. Where a Peppol invoice is the answer, you can generate and validate one for free with the tools on this site, and deliver it over the network with an account.
