Anton Collins Mitchell competitors and assessment
Company assessmentBroad incumbents
- BDO USA: BDO USA is the direct parent and operating entity that absorbed ACM in 2020. It offers the same six service lines (audit, tax, advisory, BDO Digital, industry specialty, sustainability) at a national scale and is the most directly comparable platform to the post-acquisition ACM practice.
- Deloitte US: Deloitte is one of the Big 4 and a broad incumbent across audit, tax, advisory, and digital services. It is the primary large-firm competitor for ACM/BDO's enterprise and upper-mid-market clients, especially in advisory and digital transformation.
Direct peers
- RSM US: RSM is the leading U.S. mid-market audit, tax, and consulting firm and BDO's closest peer. It serves the same middle-market and PE-backed clients with similar advisory, consulting, and digital service offerings, making it the cleanest comparable for ACM/BDO.
- CliftonLarsonAllen (CLA): CLA is a top-10 U.S. accounting and advisory firm focused on mid-market companies, closely matching ACM/BDO's target client profile and service mix across audit, tax, wealth advisory, and consulting.
- Grant Thornton: Grant Thornton is a global audit, tax, and advisory firm with a strong U.S. mid-market practice. It competes head-to-head with BDO/ACM for the same mid-market and large-enterprise engagements and offers a comparable service portfolio.
- Plante Moran: Plante Moran is a top U.S. accounting, tax, and business advisory firm with deep industry specialization in manufacturing, healthcare, and financial services — verticals where ACM/BDO also focuses.
- Crowe: Crowe is a national public accounting and consulting firm with audit, tax, advisory, and digital services. Its mid-market focus and service-line breadth closely match the post-acquisition ACM/BDO offering.
- Wipfli: Wipfli is a top-20 U.S. accounting and consulting firm with strong audit, tax, technology, and outsourced accounting practices for mid-market clients. It competes with ACM/BDO across nearly every service line.
Regional players
- Eide Bailly: Eide Bailly is a top-25 U.S. accounting firm with a comparable regional footprint in the Mountain West and Midwest. It mirrors ACM's pre-acquisition shape as a multi-office regional firm serving mid-market clients before being absorbed into national scale.
- Moss Adams: Moss Adams is a large West Coast–anchored accounting and consulting firm with industry depth in healthcare, manufacturing, and consumer products. Its geography and vertical focus overlap with ACM's Rocky Mountain and industry strategy.
