Countries and languages
Six countries. Five languages. No confusing the two.
There is no correct language for Belgium. That is precisely where software that collapses country and language into one field breaks — which is why here they are two.
Your country of registration decides
- Which tax rates and tax kinds exist
- How invoice numbers may be formed
- How long a document must be kept
- Which e-invoicing format is required
- Which currency the books are kept in
Your language decides
- Which words you read on screen
Nothing else. You can change it whenever you like, including here without being signed in — and not one line of your accounting changes as a result.
How far each country has come
All six countries can invoice, keep books and report. They differ in how deeply the national rules are modelled and, above all, in whether the legally required transmission route exists. Today it exists in none of them. Where a country demands such a route — France, Belgium, Poland — that is stated below in as many words. No country is presented as finished when it is not.
| Code | Country | Currency | What is modelled |
|---|---|---|---|
| DE | Germany | EUR |
VAT at the standard and reduced rate, reverse charge, national numbering and retention rules, e-invoicing validated against the official rule corpora. Germany prescribes no transmission route: the finished file goes out by e-mail or any agreed means. You have had to receive e-invoices since 1 January 2025; you must issue them from 1 January 2027 if your prior-year turnover exceeded 800,000 euro, otherwise from 1 January 2028.

| FR | France | EUR |
French VAT and identifier formats, the European invoice standard, Factur-X. The national mandate takes effect on 1 September 2026: from then, invoices and reporting data must travel through an approved platform (plateforme agréée). KRONENWERK is not an approved platform and hands nothing to one. You can produce and check documents here; the route to the platform is something you must cover elsewhere. Limited — at least one mandatory process is not yet possible Subscription: Available |
| BE | Belgium | EUR |
Belgian VAT and enterprise numbers, the European invoice standard, Peppol BIS — and the interface in Dutch or French. Since 1 January 2026 structured invoices between Belgian businesses are compulsory; the Peppol network is the route foreseen for them, and where a recipient cannot use it the administration allows a secure alternative the parties agree on. KRONENWERK is not a Peppol access point and does not send over the network today. The structured file is produced and checked here; sending it is currently a service provider's job. A PDF by e-mail does not satisfy the obligation, and we present it as satisfying it nowhere. Limited — at least one mandatory process is not yet possible Subscription: Available |
| PL | Poland | PLN |
Polish VAT and tax identifiers, books kept in złoty, interface in Polish, FA(3) as the format. Important, and to be read before deciding: KSeF has been compulsory since 1 February 2026 for the largest businesses and since 1 April 2026 for everybody else, and in Poland an invoice comes into existence only when KSeF accepts it and assigns it a number. KRONENWERK does not submit to KSeF today. So no invoice is issued here for a Polish business: the attempt is refused, with that reason, rather than producing a file that is not an invoice. You can still open an account; incoming invoices, master data, books and reports are all available to you.

| US | United States | USD |
Invoices without VAT logic, with the state as its own field — because sales tax there does not hang off the country. No rate table, because we will not invent one. Ready — every mandatory process of this country can be completed Subscription: Available |
| CA | Canada | CAD |
Federal and provincial taxes side by side on the same line, province as its own field, books in Canadian dollars. Ready — every mandatory process of this country can be completed Subscription: Available |
Your country
And if your country is not on the list?
Then it is better to wait. Adding a country here means writing its own rule set, not adding a row to a list. We do not switch on a country whose tax law we have not modelled.
