Profi Group provides legal assistance with temporary and permanent residence registration in Saint Petersburg and the Leningrad Region. The company helps clients navigate the application process through multifunctional centers (MFCs) and the Ministry of Internal Affairs, with payment made upon receipt of the service. Its offerings include temporary registration in Saint Petersburg and the wider region, as well as permanent registration in both locations. The website lists options with different durations and prices, and notes that applicants must be personally present when submitting certain applications at an MFC.

The service is intended for people who need to document their place of residence for everyday and administrative purposes. These may include students, employees, families with children, and people renting accommodation for an extended period. Registration may be relevant when arranging school or kindergarten enrollment, accessing medical services, or handling other matters tied to a local address. Profi Group also provides information for property owners, answers frequently asked questions, and accepts service inquiries by phone or through messaging apps.
