Accounting software is a plain thing: it holds the books of a business, issues the invoices the business sends, records the bills and receipts the business pays, tells the owner what is owed in both directions, and gives the accountant what the accountant needs at year-end. What makes it hard is that each of those sentences means something different in Montreal, in Munich, in Marseille and in Miami — a different invoice, a different tax structure, a different word for the same thing, a different set of rules about what a record must look like. KRONENWERK is one accounting product with one set of books that produces the right invoice for the seller's country and refuses the wrong one before it exists. This hub explains what to expect from accounting software today and points to the pages for the places it serves.
What accounting software has to do in 2026
- Issue the invoice the country requires
- In Germany and France the invoice is a structured file — XRechnung, ZUGFeRD, Factur-X — validated against EN 16931 before it has a number; in Belgium it travels over Peppol; in Poland it is an FA(3) for KSeF. In Québec it carries two taxes on separate lines with two registration numbers; in Ontario one HST line; in the United States whatever named jurisdiction taxes the seller is registered to collect. Software that gets this right for one country and pretends for the others is a liability the day you sell across a border.
- Keep books that are books
- A double-entry ledger, append-only, where every entry names the document it came from; issued documents frozen the moment they exist; corrections as credit notes, never edits; an audit trail with who and when. This is what an auditor, a bank and a tax authority read; a product that stores invoices in a list and calls it accounting is not one.
- Take the paperwork off the owner
- Receipts photographed, supplier bills forwarded, figures read as printed, a job folder that holds the quote, the purchase order, the bills, the photos, the invoice and the payment under one number. And, now, an assistant that does the typing: "record this bill on the Meyer job" instead of seven fields.
- Let the accountant in without a second system
- The accountant opens the company with the rights the owner gave, sees every client on one screen, and finds the documents on the records they belong to — instead of receiving a shoebox in March.
- Say what it does not do
- No accounting product determines your tax rate, files your return or replaces your adviser, and the honest ones say so on the page rather than in the small print.
The places
- Montreal and Québec — GST and QST on separate lines with both numbers, French and English documents, CAD books with USD invoices, the CPA invited in.
- Germany — XRechnung and ZUGFeRD, receiving e-invoices, GoBD-shaped records, Umsatzsteuer on the document, the Steuerberater — and no DATEV, said plainly.
- France — Factur-X validated before issue, the 2026–2027 reform, TVA on the line, the expert-comptable — and the platform question answered honestly.
- Canada, United States, Belgium, Poland — the country pages, each with a section on what KRONENWERK does not do there.
One product, one set of books
The same company can invoice a customer in Ontario, one in Vermont and one in Lyon from one set of books. The seller's country decides the document — its format, its vocabulary, its checks — and the customer's country and region decide which tax structure the sale needs; the rates are the company's to state. Prices are per market, so a business in Montreal pays in Canadian dollars and a business in Hamburg in euro, with no conversion at checkout. Country-required invoicing, customers, suppliers, bills, expenses, attachments, payments, the ledger and the core reports are in every plan; the higher plans add team workflows, automation, several companies, the API and the AI assistant, and the practice plan serves accounting firms.

Three guides worth reading before you choose
- Switching accounting software — or leaving your accountant's spreadsheet: what moves, what does not, how long it takes, how to keep your accountant.
- One job, every document: why the folder around a job belongs inside the accounting, and how it stays out of the money.
- Accounting with AI: what an assistant can read, record and draft, what stays with you, and how to connect Claude in five minutes.
How KRONENWERK handles this
SUPPORTED WITH LIMITATIONS One set of books per company; invoices produced and validated for Germany (XRechnung, ZUGFeRD), France (Factur-X), Belgium (Peppol UBL, via the connected access point), Poland (FA(3), KSeF transmission not yet), Canada (GST/HST, QST, PST as named lines, two lines in the form, over the API and through the assistant) and the United States (named jurisdiction taxes stated by the seller); bills, expenses, receipts, attachments, transactions, receivables, payables, ledger and reports everywhere; the practice plan for accountants; an AI assistant through the Enterprise plan. Not done anywhere: rate determination, tax filing, payroll, an automatic bank feed. The countries page has the status per country.
Frequently asked questions
Is KRONENWERK for accountants or for businesses?
Both, on different plans. A business runs its own books; a practice runs its clients' books through the practice plan, each client remaining its own company with its own owner.
Can one company serve customers in several countries?
Yes. The seller's country fixes the document; the customer's country and region fix the tax structure of each sale; the rates are entered by the seller.
Which country is the software from?
KRONENWERK is operated from Québec, Canada, and hosted in Frankfurt, Germany. The interface exists in English, German, French, Dutch and Polish.
Does it replace my accountant?
No. It replaces the typing and the searching. The judgment — what is taxable, what is deductible, when to close — stays with you and your adviser, who can work inside the company.
Is there a free plan or a trial?
No. Every plan is paid from the first day; the pricing page says what each includes, and the country pages say what the product does not do, before you buy.
What about the United States?
Supported for invoicing and books, with named sales taxes the seller states per jurisdiction; no sales-tax determination and no filing. The United States page has the full list.
