Choosing a SOC 2 auditor
The report is only as good as the letterhead.Your SOC 2 report’s credibility comes from the CPA firm that signs it. The software behind it is invisible to your buyers; the letterhead is not.
The four things that matter
Recognition. The report’s job is to end security-review conversations. A firm your buyer’s security team has seen before does that; an unknown shingle invites re-review. Ask candidate firms which companies your size and sector they’ve audited.
Fit with your evidence. Firms experienced with your compliance platform accept its exports directly; firms that aren’t will ask for screenshots of things your platform already proves. One question resolves it: “have you audited companies using our stack?”
Timeline reliability. Good firms book out months ahead, and fieldwork slippage pushes your report — and the deals waiting on it. Get the schedule in writing: readiness review, window close, fieldwork, draft, final. Ask what their median engagement-to-report time actually is.
Price, last. First Type II engagements commonly land in the $10–30K band. The delta between a cheap firm and a good one is small against the enterprise deal the report unlocks — and re-auditing with a better firm later costs the full amount again.
Questions that separate firms quickly
How do you sample — continuous requests through the window, or one fieldwork crunch? Who exactly will be on our engagement, and what’s their SaaS background? What’s your process when you find a gap mid-window — flag and help remediate, or write the exception? How do you handle the draft review — can we correct factual errors in the system description?
The sequencing trap
Don’t pick the auditor last. Engage early — before the observation window opens — so their readiness assessment shapes the program instead of grading it. The worst money in SOC 2 is paying fieldwork rates to discover gaps a readiness review would have caught for free. In our done-for-you engagements, auditor selection happens in week one for exactly this reason.

Hands-on SOC 2 compliance services: gap assessment, control implementation, evidence collection, and audit support — platform included, experts driving.
Does the audit firm's name really matter?
To enterprise procurement, yes. A recognized firm's report gets accepted; an unknown firm's report gets questions. You don't need Big Four — you need a firm with real AICPA standing and a name security reviewers have seen before.
Can our compliance platform's marketplace auditor do it?
Often, and conveniently — marketplace firms know the platform's evidence formats, which speeds fieldwork. Do the same diligence you'd do on any firm: peer-review standing, references from companies your size, and confirmation the team assigned has SaaS experience.
Is auditor independence a real concern with bundled audit platforms?
It's a question some enterprise reviewers raise when the platform and the audit come from the same vendor. CPA firms manage independence formally, but if your buyers are conservative — banks, healthcare enterprises — a structurally separate auditor avoids the conversation entirely.
