Pricing
Priced per document. Not per seat, not per shop.
Every plan runs the same engine and the same validation. What changes is how many documents you compile each month and how long we keep them.

Questions worth asking first
What counts as a document?
One compiled Factur-X file. Validating a payload with POST /api/v1/validate does not count, so you can run schema checks in CI on every build without spending quota.
What happens when I hit the limit?
Generation returns HTTP 402 with the used and limit values, and nothing is charged or silently dropped. The counter resets at the start of each UTC month.
How long do you keep the files?
As long as the plan's retention window. German GoBD requires invoices to be retained for ten years, which the Scale plan covers — but the durable copy should be in your own archive, and every document is downloadable as PDF and XML.
Can I use my own invoice numbers?
Yes, and you should. Numbers are unique per organisation and rejected with a 409 if reused, because a duplicate invoice number is an accounting problem, not something to resolve silently.
Is this tax advice?
No. We produce documents that conform to EN 16931 and the Factur-X specification. Whether a particular invoice satisfies your obligations is a question for your Steuerberater.
