Pricing

Reading and checking an invoice will stay free. That is our way of helping people get through the September 2026 deadline. The subscription is for the API, for those who build the engine into their own tools.

Frequently asked questions

Will the reader stay free?
Yes. Reading an invoice, checking it against EN 16931 and batch processing are free, with no account. What is paid for is programmatic access (the API), to build the engine into your own tools.
Can I change tier or cancel?
At any time, with no commitment, since the subscription is monthly. You manage and cancel it yourself from your customer portal (sign in by e-mail). Cancellation takes effect at the end of the current period, and nothing is charged after that.
Will I get a compliant invoice?
Yes, with VAT handled correctly for businesses in the EU (reverse charge where it applies), issued by our billing partner.
What happens if I go over my quota?
The API returns 429 with a Retry-After header. Nothing extra is charged, and there is never a surprise overage. If you go over regularly, move up a tier or let us talk about custom volume.
