01Screen for CPA and peer-review credibility
SOC 2 reports must be issued by a licensed CPA firm. We filter for evidence that the firm can issue attestation reports buyers will accept.
We scored 181 firms on price floors, timelines, AICPA peer-review status, and GRC platform fit. The first screen is the short list; the rest of the page shows when to choose a specialist, national firm, or Big Four practice.
The union of firms we recommend by use case on the Type 1 and Type 2 pages. Sort by price or timeline to fit your constraint.

Type 2 figures are our public-records pricing estimates, refreshed periodically — not auditor-confirmed quotes. Verify AICPA peer-review status before signing.
The best auditor is usually the narrowest credible firm your customer will accept. Big-name letterhead only earns its premium when procurement explicitly asks for it.
| Factor | Specialist | National | Big Four |
|---|---|---|---|
| Best fit | First SOC 2, SaaS, startup sales deadlines | Multi-framework or larger US teams | Public-company, bank, or board-driven requirement |
| Typical cost posture | Lowest fixed-fee range | Middle of market | Highest premium |
| Speed | Fastest scheduling | Moderate scheduling | Slowest scheduling |
| Tradeoff | Less brand recognition | Less boutique attention | More process and higher fees |
The ranking favors practical buying outcomes over brand size. A firm moves up when it can issue a credible report quickly, price predictably, and fit the buyer's procurement reality.

A lower audit fee is only useful when the firm can also meet your timeline and work cleanly with your GRC stack.
Big-name firms stay on the list, but only rank first when the buyer has a real procurement reason to pay the premium.
