By Priyanka Singh India Market Analyst Published · 3 min read · 553 words
Summary: US B2B services crossed $2.7 trillion in FY2025 across strategy consulting, Big Four accounting, IT consulting + BPO, staffing, and facility services. Regulation runs through FTC, SEC, PCAOB, DOL, IRS, and state CPA boards. Datasets cover firms by category, city, specialty.

The United States b2b services industry is the largest addressable market in its category globally, generating roughly $2.7 trillion in annual revenue across the fifty states. US B2B services is the second-largest sector after healthcare, anchored by Big Four accounting, MBB strategy consulting, and Accenture-scale IT services. Consolidation runs alongside a long tail of regional and specialty operators — every state carries active players plus a mid-market layer that rarely appears in a single register.

For B2B sales and research teams — SaaS platforms, enterprise vendors, distributors, staffing agencies, market-research firms — the addressable universe is enormous but scattered across state registrations, industry associations, and public disclosures. Our verified US b2b services directory consolidates the discoverable operators into a single CSV kept fresh against FTC + SEC + PCAOB + DOL disclosures and industry-body updates. Buyers often pair this dataset with our US Professional Services, US Staffing & Workforce Services and US Legal catalogs when building multi-vertical outreach.
