The Accounting Infrastructure
01
Fully Outsourced Accounting
We take ownership of the entire accounting function — bookkeeping, close management, reconciliations, controller oversight, internal controls, and financial reporting. Built for companies that want a better accounting function without the hiring cycles, turnover risk, and quality control challenges of building one in-house.
02
Special Projects and Advisory
Defined-scope engagements for cleanup, system migrations, audit preparation, transaction preparation support, or process redesign. Expert execution, fixed timeline, clear deliverables.
Who We Serve
Built for the middle market.
Our clients are middle-market companies, PE-backed portfolio companies, and management teams navigating growth, capital events, or accounting team transitions. They need a reliable accounting function built for their stage — not a vendor, but an embedded infrastructure partner.
Private Equity Portfolio Companies
Rapid financial infrastructure, clean reporting, audit readiness.
Founder-Owned Businesses
Accounting infrastructure that supports growth, lender reporting, and leadership decision-making.
Teams in Transition
Sale, acquisition, or leadership change stabilized quickly.
