What we do

A full back office — without the overhead.

Tax preparation & filing

Federal and state returns for individuals, LLCs, S-Corps, and C-Corps — filed on time, every time.

Sales & payroll tax

Multi-state sales tax, quarterly 941s, NYS-45s, and state unemployment — handled end-to-end.

Advisory & CFO services

Cash-flow forecasting, KPI dashboards, and quarterly reviews to help you make better decisions.

Catch-up & clean-up

Behind on books? We rebuild months or years of history and get you compliant, fast.
