What are the conditions for joining the test (beta) operation at the software supplier?
Short answer
There are no uniform legal conditions for engaging in test or beta operation. The conditions are determined by each software supplier separately. Some suppliers allow testing for all customers, others make it available gradually or only to selected clients.
June - October 2026 (usually given)
Most software vendors plan to launch during this period.
Registration according to § 4
Typically required, as it concerns persons obliged to issue e-invoices.
Not just a demo environment
A vendor production application, not an educational tool.
Simultaneous testing of both sides
Necessary business partner involved at the same time, plus providing feedback to the supplier.
Conclusion
The conditions for participation in the test or beta operation of electronic invoices are not uniformly determined by legal regulations. Each software supplier can define its own rules, scope of testing and range of involved users. It is therefore recommended to check the specific conditions directly with your software supplier before joining.
