Meet Our Founder, Matthew
Matthew Troisi is the founder of Troisi Bookkeeping Services, LLC, a virtual bookkeeping firm serving law firms, professional services companies, and business owners operating complex multi-entity structures across Massachusetts and beyond.
With a bachelor's degree in finance and a minor in economics from the University of New Hampshire, and a professional background spanning financial management and IT consulting operations, Matthew brings a level of financial sophistication that goes well beyond standard transaction recording. He has built a practice that manages the financial records of businesses generating up to $5 million in annual revenue, from growing law firms and multi-entity organizations to professional services companies that have outgrown their current bookkeeping solution.
Matthew specializes in two things: rebuilding financial records that have fallen behind, including multi-year cleanups for businesses navigating audits, entity transitions, or years of mismanaged books, and maintaining accurate, tax-ready financials on an ongoing monthly basis. As a Certified QuickBooks Online ProAdvisor, his clients receive organized financial reports, clean books their CPA can work from directly, and a bookkeeper who responds when they reach out.
Whether you are managing a growing law firm, running a multi-entity business structure, or leading a consulting practice with books that need to be rebuilt before they can be maintained, Troisi Bookkeeping Services is built for businesses that take their finances seriously.
