FAQ: Choosing the Best SOC 2 Auditor
Does the auditor's brand name matter?
Yes, but mostly for enterprise deals. If you sell to banks or Fortune 500s, a "Big 4" name (Deloitte, PwC, etc.) helps. For 99% of B2B SaaS startups, a respected mid-market firm (like the ones ranked #1-3 above) is perfectly acceptable and costs 50% less.
What if I choose a bad auditor?
The risks are: 1) Your customers reject the report, forcing you to pay for a re-audit. 2) The auditor is slow/unresponsive, delaying your sales deals. 3) They nickle-and-dime you with hourly fees.
How do I verify an auditor?
Ensure they are licensed CPAs and have a valid AICPA peer review. All auditors listed on SOC2Auditors.org have been manually verified against these criteria.
