Commercial model / October 2026
Stampbench separates open-source validation from professional implementation. There is no artificial licence gate around the local engine.
Open-source core
Install the TypeScript library or CLI, run validation locally and maintain the integration inside your own team.
Founding integration pilot
Stampbench works with your engineering team to put the current validator into one real staging workflow and document the result.
Managed hosting, private deployments and guaranteed response times are not sold as standard services today. Any continuing work is agreed only after a successful pilot.
You do not need to pay Stampbench for permission to use the library. The pilot pays for defined integration work, testing against your representative invoices, diagnostic mapping and a documented handover.
It is the initial test price for a tightly bounded pilot. Scope and acceptance criteria are agreed before work starts. Wider formats, additional products or custom national rules are quoted separately.
No. Stampbench implements a documented subset of supported EN 16931 and XRechnung rules. The pilot supplies validation tooling and test evidence, not legal advice, certification or a guarantee of recipient acceptance.
There is no automatic subscription. If continuing engineering support or shared infrastructure would be useful, it is scoped only after the pilot has established what your team actually needs.
