Kancelaria Księgowa Agnieszka Janik

What Kancelaria Księgowa Agnieszka Janik does

Kancelaria Księgowa Agnieszka Janik is a privately held Polish accounting and tax-advisory firm founded in 2005 and headquartered in Warsaw, operating under the legal name Kancelaria Księgowa Janik Agnieszka. The firm delivers a unified portfolio of bookkeeping, payroll, and annual tax-filing services to two primary customer segments: small and medium-sized enterprises requiring ongoing accounting, and individuals requiring annual PIT settlements across all major Polish tax forms (PIT-16A, PIT-28, PIT-36, PIT-36L, PIT-37, PIT-38, PIT-39). Add-on services include internal audits, prior-year documentation remediation, tax and legal advisory, and representation before the Polish Tax Office (Urząd Skarbowy) and ZUS.

The firm's underlying technology consists of a modern online accounting system delivered through its OSCBR partnership with mBank and SuperKsięgowa, which provides the client-facing accounting platform. There is no proprietary software product; the firm is a service-based practice rather than a technology platform. Operations are delivered through a single Warsaw office at ul. Krakowiaków 103, supplemented by phone, email, and remote document exchange. The website reports a 20-person team, though firmographic data lists 9 employees, indicating an unresolved discrepancy.

The business model is service-based recurring revenue with seasonal PIT-filing volume. PIT filings are priced on a unit basis at 80-300 PLN per return depending on form complexity, while ongoing bookkeeping and payroll contracts are individually negotiated based on document volume and business complexity. Distribution is primarily direct-to-client (phone, email, in-person visits), with an additional referral channel through the OSCBR-mBank partnership. The firm claims 180+ clients, processes 200,000+ documents annually, and manages payroll for 900 individuals per month. No funding rounds, acquisitions, or institutional ownership are present; the firm is founder-owned and operated by Agnieszka Janik.
