About the firm
Compliance, done well, is a competitive advantage.
We started in 2017 from a single desk in Prayagraj, handling the first incorporation for a local stationery shop. Nine years later we file for 340+ entities — from family businesses in UP to a US-based accounting client — across secretarial, taxation, IP and US accounting verticals.
We are here to serve — founders, promoters and businesses across India who need a firm that understands the law, meets every deadline, and gives them a straight answer.
