Good day. The collaboration went excellently, Anna is a wonderful client. Despite the language barrier, we found common ground in English. She sets tasks clearly, is always friendly, and patiently explains things related to the specifics of European and Polish legislation. Immersing myself in the context did take me a bit longer than I expected, but as a result, we produced a fantastic product that will save Anna a huge amount of time in sending invoices to KSeF.

A bit about the product. It allows integration of 1C/BAS with KSeF (the invoice registration system in Poland, which will be mandatory for everyone starting in 2026). It generates XML in the form of a file and allows it to be sent to KSeF via API. For the testing environment, it obfuscates data to prevent sensitive client information from entering the external environment.
