Great overall experience, highly recommend

Flexinwork helped with all our paperwork in Poland, including our residence permit, PESEL number, and driver's license. Everything was handled quickly, with full support throughout the process, so we didn't have to deal with unnecessary hassle.

They also helped us set up a company in Poland and take care of the accounting. They were always available, explained everything clearly, and stuck to the agreed timelines.

One of the biggest advantages is that they speak both Russian and English, so there was never any language barrier. It's also really convenient to have everything in one place so you don't need to look for separate lawyers, accountants, or HR services.

Clear pricing, professional service, and a smooth experience from start to finish. We highly recommend them to anyone moving to Poland or looking to run a business here without unnecessary stress.
