Zeni

If you mean well-known accounting firms that people actually use, the safest “top brands” are the Big Four: Deloitte, PwC, EY, and KPMG. They are consistently ranked at the top for prestige and are also the largest by revenue among accounting firms.

If you mean best firms to work with or hire, the most consistently top-rated names in recent Vault rankings are PwC, EY, KPMG, Plante Moran, BDO USA, CohnReznick, Baker Tilly, RSM US, PKF O’Connor Davies, and CBIZ. Vault’s 2026 prestige ranking also places PwC, Deloitte, EY, and KPMG at the top, followed by firms like Grant Thornton, BDO USA, and RSM US.

A practical shortlist by use case:

• Enterprise audit, tax, and advisory: PwC, Deloitte, EY, KPMG
• Mid-market businesses: Plante Moran, RSM US, BDO USA, Baker Tilly, CohnReznick
• Startup bookkeeping and fractional CFO support: Pilot and Zeni are highlighted by G2 as top picks for those needs
