Boutique specialist 65 firms
Tech-focused, often automation-platform-native firms. Fastest turnarounds and lowest pricing. The usual first-audit pick for startups and SaaS Series A through C.
National & regional 86 firms
Established CPA firms with a SOC 2 practice — name-brand nationals (RSM, BDO, Grant Thornton, Crowe, Baker Tilly) surface first, regional firms follow. The usual fit for growth-stage SaaS and companies whose enterprise buyers do not specifically require a Big 4 report.
Big 4 — for regulated industries & public-company prep 17 firms
Global firms. Deepest brand recognition, deepest cost. Suited to regulated industries, public-company prep, and enterprise buyers who require a Big 4 letterhead. Skip this section unless one of those applies.

Buyer questions
How this directory works.
Four questions on choosing a firm, what "verified" means, how pricing is sourced, and how the matching flow works for buyers who skip the filter and tell us their scope.
How do you choose a SOC 2 auditor from this directory?
Filter by your company size, industry, and budget. The size filter groups firms by who they actually take engagements from: startup (under 50), SMB (50–500), mid-market (500–2,000), enterprise (2,000+). Specialist firms ($15K–$70K Type 2) suit startups and SaaS; national and regional CPA firms ($25K–$110K) suit growth-stage companies; Big Four ($45K–$430K) suit regulated industries and public-company prep. Verify AICPA peer-review status before signing. See /soc-2-audit-cost/sources/ for how each range is calculated.
What does 'verified' mean in this directory?
Verified firms have a confirmed CPA license, AICPA peer review on file, and at least one verified SOC 2 client reference. We re-check verification quarterly.
How is pricing sourced?
Pricing ranges come from direct outreach to each firm and interviews with their clients. Ranges are refreshed quarterly and tagged with a last-verified date.

About this data.
Timeline and pricing estimates are based on anonymous quote requests and verified client interviews conducted by our research team. Actual pricing varies based on company size, complexity, and scope.
We distinguish between CPA firms (who can issue the final SOC 2 report) and preparation partners (who help you get ready). All "Top 10" ranked firms are licensed CPA firms capable of issuing reports.
