SOC 2 cost: 12 questions practitioners actually ask.

Type 1 is a point-in-time attestation of control design. Type 2 is a period attestation across a 3 to 12 month observation window, with sample testing across a population of evidence and walkthrough revisits at the close. Those extra workstreams are auditor hours a Type 1 never incurs, so a Type 2 costs meaningfully more for identical scope. How much more is not published by any firm. The strategic question is rarely the fee gap anyway: it is whether the customer or investor deadline can wait the longer Type 2 timeline.

Type 1 runs 3 to 6 months end to end. First-time Type 2 runs 9 to 12 months: readiness 2 to 3 months, an observation window of 3 to 6 months, then fieldwork and reporting. Subsequent annual cycles are shorter because readiness drops out. The floor is structural rather than commercial: a Type 2 cannot be shorter than its observation window, and the minimum window is typically 3 months.

SOC 2 is not legally mandated. It is customer-required in B2B SaaS, particularly where the buyer is regulated, and investor-required at series A or B fundraises. Compare with HIPAA or PCI DSS, which are obligation-driven. SOC 2 is an attestation performed by CPA firms licensed by state boards of accountancy, under professional standards published by the AICPA.

Market-driven. A US-leaning customer base makes SOC 2 the dominant signal. EU, UK and international buyers expect the structured ISMS that ISO 27001 certifies. If you need both within 12 months, running them as one programme with one readiness workstream costs less than running them twice, because the control sets overlap heavily and the evidence is largely the same evidence. How much less depends on your scope and on whether the evidence is genuinely shared. No firm publishes a bundle discount.

The platform part is knowable: GRC vendors publish annual list prices on AWS Marketplace, and at startup headcount the published platform lines start at $7,500 a year, with several vendors billing the first compliance framework as a separate item on top. The audit part is not knowable in advance, because no firm publishes fees. So the honest startup answer is: price the platform from the published SKUs, get two audit quotes on identical scope, and model the internal time at your own loaded rate. Anyone quoting you a single all-in startup figure has estimated it.

Consultants quote readiness per engagement and do not publish day rates, so there is no honest number to give you. What is useful is knowing what you are buying, because three different things get sold under the word readiness: a gap analysis, which inventories controls and rates what is missing; a readiness assessment proper, which adds an evidence map, a remediation order and a timeline; and the remediation engagement itself, which is hands-on work and is usually the largest of the three. GRC platforms typically include the gap analysis in the subscription.

Nobody outside the engagement knows. No Big 4 firm publishes SOC 2 fees anywhere, and neither do the mid-tier firms or the boutiques. There is no register, no rate card and no filing. Any specific Big 4 figure you find has been estimated by whoever published it. What is true structurally: all three tiers issue the same attestation under the same AICPA standards, so a boutique's SOC 2 report is not a lesser instrument, and the Big 4 premium is only worth paying where a downstream buyer requires that signatory by name.

A SOC 2 report covers a stated period, typically 12 months for a Type 2, and customers expect annual renewal. SOC 2 has no formal surveillance audit, unlike ISO 27001, so each annual report is a full re-audit against a fresh observation window rather than a lighter check-in. Lapsed reports beyond 12 months are typically rejected by enterprise procurement.

Security is mandatory and is the only category every SOC 2 report must include. The other four, Availability, Confidentiality, Processing Integrity and Privacy, are optional and driven by what your customer contracts require. Each one you add brings controls that have to be tested, so each adds auditor hours and readiness work. No firm publishes a per-criterion figure, so treat any specific percentage you see, including the modelled bracket on this site, as an assumption rather than a fact. Scope only what customers actually ask for: scope grows easily at renewal and shrinks with difficulty.

Yes. The audit firm is non-negotiable, but the platform is not. Doing it yourself means in-house readiness, in-house evidence collection and in-house policy work, plus the same CPA audit. The trade-off is not cash against cash so much as cash against the concentration of several hundred hours on one senior engineer. It needs a lead with real free time, a lightweight evidence system, and existing security hygiene good enough that readiness is a formalisation rather than a rebuild.

Less than year 1, but not for the reason people expect. Readiness and remediation drop out, which is the real saving. The audit does not get much lighter: SOC 2 has no surveillance audit, so year 2 is a full re-audit of a fresh observation window. The platform contract renews at list. Internal time falls because the evidence rhythm already exists. The confident year-2 ratios in circulation are not published by anyone, so ask your firm what year 2 looks like before you sign year 1.

Figures update when the underlying reality changes, not on a calendar. The GRC platform prices are re-read from the vendors' AWS Marketplace listings and carry the date they were checked. The model changes when its assumptions change, and the change is logged. Triggers include an AICPA standards revision, a vendor changing a published SKU, and any correction we receive and verify. There are no cosmetic date bumps, and every substantive revision is logged with its date on the updated page.
