Frequently asked questions

Developers are the people who write code against the library. Build servers, test and production systems and the users of your applications do not count – servers, applications and processed invoices are unlimited. The license applies to your company; external developers may work with it on your behalf. To switch from Team to Enterprise, send us an email and we will send you a quote.

Yes, in both tiers and at no extra cost: as part of your applications to your customers and when running them as SaaS. Passing on the library on its own or as a developer tool is not permitted. Ship the third-party notices with your application. The details are in the terms (§ 6).

All versions released in the 12 months after your key is issued keep working indefinitely, so your invoice processing never stops. During that time you receive all updates we release. The price is an annual price for these 12 months of updates. Newer versions after that are available when you buy a further update year; there is no automatic renewal.

An example:

Date What happens Your key
1 Mar 2026 You buy a license and receive your key. Updates until 1 Mar 2027
1 Apr 2026 Version 2 is released. Works with the same key.
15 Mar 2027 Version 3 is released. No longer works with this key, because it was released after 1 Mar 2027.
after that You stay on version 2. Keeps working indefinitely. Your application is not stopped.
10 Apr 2027 You buy a license again and receive a new key. Updates until 10 Apr 2028. Version 3 works with it.

Anyone processing e-invoices almost always needs both in practice: validating incoming documents and creating outgoing invoices. That is why one license unlocks both libraries – you only reference what you actually use.

You receive the key by email and can find it in your customer account at any time. Register it once at program start:
