Acquire a Financial Audit Firm
Business

Financial audit firms provide assurance services including financial statement audits, reviews, and agreed-upon procedures primarily for private companies, nonprofits, government entities, and regulated industries. The lower middle market segment is highly fragmented with thousands of independent CPA firms competing alongside regional and national players. Demand is largely driven by regulatory requirements, lender covenants, and investor due diligence needs, creating a relatively stable and recurring revenue base.

Who buys these: CPA firm owners, regional accounting firm partners, private equity-backed accounting roll-ups, independent CPAs seeking to expand service lines, and strategic acquirers looking to add assurance capabilities
