174 firms SOC 2 Auditor Firms.

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 (500–1,000), enterprise (1,000+). Specialist firms ($15K–$50K Type 2) suit startups and SaaS; national and regional CPA firms ($30K–$80K) suit growth-stage companies; Big Four ($60K–$200K) 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.

It means our research team has checked the firm against public records: that it operates under the listed name, that it's a licensed CPA firm able to issue SOC 2 reports, and — for US firms — that we located its AICPA peer-review record. Each firm carries trust badges showing exactly which of these we confirmed, and the date we last checked. Where we could not confirm something, the firm stays listed with a caveat badge rather than being hidden. We re-check periodically.

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.
