To ensure smooth testing for all users, Poland’s National e-Invoicing System (KSeF) has implemented temporary restrictions. These limitations address the increased demand on the test server, which has led to challenges for developers and businesses testing the system.
KSeF limitations now in place:
- File size: test requests are limited to 10 MB per submission.
- Submission rate: users may only submit up to 100 requests per minute. Exceeding this limit results in temporary IP blocks, beginning with a one-minute suspension, increasing incrementally to 10 minutes per violation.
These measures aim to stabilize the system during heavy use. It’s essential to note that the test server is not designed for performance testing but rather for functional tests and simulations. The goal is to allow as many users as possible to benefit from the environment while ensuring its reliability.

Key takeaways:
The new test restrictions are:
- 10 MB per request.
- 100 submissions per minute.
- IP blocking for violations.
- KSeF’s test server is for function testing only, not performance or stress tests.
