A SOC 2 audit is the US B2B SaaS compliance tax. If your enterprise prospects are asking for one — and in 2026 they almost always do — this is what it will cost, and how long it will take.
Total 2026 Cost for a US Startup
| Stage | Automation platform | Auditor (Type I) | Auditor (Type II) | Policy / consulting | Total year 1 |
|---|---|---|---|---|---|
| Seed (≤30 people) | $8K – $18K | $8K – $15K | $12K – $25K | $0 – $5K | $20K – $45K |
| Series A (30–100) | $12K – $28K | $12K – $20K | $18K – $35K | $5K – $15K | $35K – $75K |
| Growth (100–500) | $25K – $60K | $20K – $35K | $30K – $70K | $10K – $40K | $75K – $180K |
Year 2 costs drop 30–50% once initial policy work is done and the first audit cycle is complete.
Type I vs Type II
Type I is a point-in-time attestation — "on this date, these controls were designed correctly". Fast and cheaper, but most enterprise buyers now treat it as a weak signal. Useful as a bridge if you need something before you can complete a six-month observation period.
Type II is what buyers actually want. It observes the operating effectiveness of controls over 6–12 months. Expect:
- 6 months is the minimum observation window most auditors accept.
- 9 months is the sweet spot for first-timers (lets you fix a control if it fails early in the window).
- 12 months is standard for renewals.
If you're pre-revenue, start with Type I to unblock pipeline and transition to Type II at the next audit cycle. If you have signed logos asking for SOC 2, go straight to Type II and plan for a 9-month timeline.
Where the Money Goes
Compliance automation platform (30–40% of year-1 spend). Vanta, Drata, Secureframe, Sprinto, Scrut and others sit at ~$8–30K/year for startups. They do evidence collection, control monitoring, and policy templates. For a seed-stage team, the automation platform is cheaper than hiring one GRC person.
Auditor fees (30–45%). A CPA firm licensed in your state does the attestation. Prices vary heavily by firm size and scope:
- Boutique SOC 2 specialists (Prescient, Johanson, Insight Assurance, A-LIGN's lower tier): $8K–$18K Type I, $12K–$28K Type II for a seed-stage single-product scope.
- Mid-size CPA firms: $15K–$35K.
- Big-four and Schellman: $35K–$80K+. Overkill for most startups.
Get three quotes. Prices for identical scope swing 2–3x across firms.
Internal time (hidden 20–30%). A seed-stage founder or senior engineer typically burns 60–120 hours getting SOC 2-ready in the first 3 months. Price that at your fully-loaded rate.
Consulting / vCISO (optional, 10–20%). If no one on the team has done SOC 2 before, a readiness consultant for the first 3 months is $5K–$20K. For later stages, consider a fractional CISO at $3–8K/month.
Timeline
- Weeks 1–4: Scope the audit (which product, which systems, which TSC categories). Pick an automation platform. Begin policy drafting.
- Weeks 5–12: Close control gaps (MFA everywhere, logging, access reviews, vendor management, incident response plan). Collect first evidence.
- Month 3: Start the Type II observation window.
- Month 9: Field work with the auditor. 2–3 weeks of interviews and evidence review.
- Month 10–11: Receive the report.
Many startups try to compress this to 4 months. It's possible for Type I; impossible for a meaningful Type II.
Scope Decisions That Save Money
- One product, one environment. Multi-product scope doubles auditor hours.
- US-only or add a region later. Multi-region scoping adds cost without buyer value in year 1.
- Common Criteria only + Confidentiality. Skip Availability and Processing Integrity unless a customer specifically asks. Many startups add Privacy only if GDPR is already a factor.
- Grey-box pen test, not full red team. You'll need an annual pen test; keep it scoped.
When Not to Do SOC 2 Yet
- No signed logos or imminent deals requiring it. Spend the money on sales.
- A single enterprise prospect is asking for it. First check if a signed security questionnaire and MSA can unblock them.
- You're in a regulated industry where HIPAA or PCI DSS is the actual requirement; SOC 2 may be redundant.
