Questions
Frequently asked
Why does it start with a paid diagnosis?
Because a fixed price needs a fixed scope. The diagnosis (690 PLN, about 3 business days) gives you a process map, the cost of manual work and a priced plan. If you go ahead, the full amount is deducted from the build.
What if the build takes longer than estimated?
The scope is closed before work starts. If it takes me longer than planned, you do not pay for the extra hours.
Do I have to buy a care plan?
No. The care plan covers monitoring, backups, security updates and small changes. Without it the system keeps working, but nobody watches it for you.
Can you work with a company outside Poland?
Yes, as long as the process can be handled remotely. Most clients are Polish companies or foreign-owned subsidiaries in Poland that need KSeF.
What about modules that are not on this page?
Engines still in development are priced after the diagnosis, so you never get a list price for something that is not finished yet.
