Pillar / Budget sanity check by company size

SOC 2 cost for startups: seed to Series A budget ranges.

A startup pursuing SOC 2 is usually responding to a single deal-blocking customer. Cost should be sized to that, not to aspirational scale. This page sets out three sub-brackets and the cheapest credible path at each.

Section 01

Three sub-brackets

Startup SOC 2 budget by headcount, mid-tier or boutique CPA

Bracket	Recommended path	Year-1 all-in
5 to 15 employees	Type 1 only, boutique CPA, entry-tier platform	£15,000 – £35,000
15 to 30 employees	Type 2 directly, boutique or mid-tier CPA, entry-tier platform	£25,000 – £50,000
30 to 60 employees	Type 2, mid-tier CPA, mid-tier platform, possibly + Confidentiality	£35,000 – £70,000

The brackets above assume Security only at the smallest scale, with Confidentiality added as the team grows. Adding more Trust Services Criteria from day one is rarely justified for a startup; scope can grow at renewal once customer demand confirms it.

Section 02

The readiness-vs-audit ratio at startup stage

At larger scale, audit fee dominates and readiness is a small share. At startup stage, the ratio inverts. Readiness can cost more than the audit because the policies do not exist yet, the access reviews have never happened, and the vendor inventory is implicit. A typical first-time SOC 2 readiness for a 20-person SaaS runs £8,000 to £20,000 against an audit fee of £15,000 to £25,000. Plan for a 1:1 readiness-to-audit ratio at this stage.

Section 03

What founders consistently underestimate

Engineering time stolen from the product roadmap. SOC 2 consumes 200 to 500 hours of senior engineering time across 6 to 9 months. Every one of those hours is not building product. For a startup chasing product-market fit, the opportunity cost is real and large.

Founder and CEO interview time during audit walkthroughs. Auditors interview control owners, and at startup stage the founder is the control owner for governance, vendor management, business continuity, and risk assessment. Plan for 8 to 16 hours of founder time during audit fieldwork on top of readiness.

Customer-friction during evidence collection. Some evidence requires customer cooperation (DSAR drills, vendor questionnaire samples, contract reviews). Customers are willing to help, but it is friction nonetheless. Plan one customer-facing communication per month during the observation window.

Section 04

Cheapest-but-credible path

Below £30,000 for a Type 2 attestation, scrutinise the audit firm. The AICPA peer review status, recent SOC 2 issuance history, and engagement-letter clarity are all checks worth running before signing. A clean firm at low cost exists; a cheap firm with shortcuts exists; the difference is visible in the engagement letter.

FAQ

What is the cheapest credible SOC 2 path?+

For a 25-person SaaS, the cheapest defensible path is a boutique CPA firm plus an entry-tier platform (Sprinto or Comp AI) plus roughly 200 internal hours. Total year-1 lands around £30,000 to £40,000. Below that figure, scrutinise the firm's AICPA standing and the platform's framework coverage.

Should we get SOC 2 before product-market fit?+

Generally no. SOC 2 is responsive: it answers a deal-blocking customer requirement. Pre-product-market-fit, it consumes founder attention without unlocking revenue. The exception is regulated-buyer markets (fintech, healthtech) where SOC 2 is a precondition for early customer conversations.

Can a 5-person startup get SOC 2?+

Yes, with caveats. The cost shape is largely fixed regardless of team size, so a 5-person startup pays nearly the same audit fee as a 30-person startup. The internal hour cost is concentrated on one or two founders. Year 1 typically lands at £20,000 to £40,000.

Should the founder run SOC 2?+

Below 30 employees, often yes (technical co-founder). Above 30, delegate to a senior security or platform engineer. The founder running SOC 2 has the advantage of cross-functional authority; the disadvantage of opportunity cost on product or fundraising.
