How Much Does a SOC 2 Audit Cost?

Understanding SOC 2 Audit Pricing

The cost of a SOC 2 audit is not one-size-fits-all. Pricing depends on multiple factors including your organizational complexity, the Trust Services Criteria you select, and the type of firm you engage. Understanding these variables helps you budget accurately, compare proposals meaningfully, and avoid surprise costs.

The total cost of SOC 2 compliance extends beyond the audit fee itself. Organizations should plan for readiness preparation, compliance tooling, internal team time, and ongoing maintenance costs. Viewing SOC 2 as a total cost of ownership — rather than a single audit expense — leads to better budgeting and fewer surprises.

Auditsuisse Standard SOC 2 Pricing

Unlike most audit firms, Auditsuisse publishes its standard fees. For SOC 2 engagements scoped to the Security (Common Criteria) Trust Services Category, standard fixed-fee pricing is based on company headcount:

This is base pricing for standard engagements — fees may be higher in specific instances, such as complex products, services, or system descriptions, complex cloud environments, or on-premise infrastructure, and each engagement may be priced higher or lower at scoping. Additional Trust Services Categories (Availability, Confidentiality, Processing Integrity, Privacy) are scoped and quoted at the scoping call. Every engagement requires individual approval and confirmation of auditor independence before an engagement letter is issued. See the full SOC 2 pricing schedule for inclusions, conditions, and market comparisons.

Factors That Influence SOC 2 Audit Cost

• Report type (Type I vs Type II) — Type I engagements evaluate controls at a point in time and are generally less costly. Type II engagements cover a 6-to-12 month observation period, requiring more auditor time for evidence review and testing.
• Number of Trust Services Criteria — Every SOC 2 audit includes Security (Common Criteria). Each additional category — Availability, Processing Integrity, Confidentiality, Privacy — increases the scope of testing and the number of controls to evaluate.
• Organizational complexity — The number of in-scope systems, cloud environments, third-party integrations, office locations, and employees all affect how much work the audit requires.
• Readiness level — Organizations with mature control environments, documented policies, and evidence already in place require significantly less auditor time than those starting from scratch.
• Firm type and size — Big 4 firms command premium rates. Mid-market regional firms offer moderate pricing. Specialist firms like Auditsuisse provide competitive pricing with dedicated senior auditors and industry-specific expertise.
• Geographic considerations — Organizations with operations in multiple jurisdictions may face additional complexity, though dual-headquartered firms like Auditsuisse can streamline cross-border engagements.

Hidden Costs of SOC 2

The audit fee is only part of your total SOC 2 investment. Organizations frequently underestimate these additional costs:

• Compliance platform subscriptions — Tools like Vanta, Drata, Secureframe, or Sprinto automate evidence collection but add annual subscription costs.
• Internal team time — Your engineering, security, and operations teams will spend significant time gathering evidence, answering auditor questions, and implementing controls.
• Remediation work — Gap analysis often reveals control deficiencies that require technical implementation — new monitoring tools, access control changes, policy updates.
• Policy and procedure documentation — Creating and maintaining the security policies, procedures, and evidence that underpin your controls.
• Penetration testing — Many organizations include annual penetration tests as part of their SOC 2 control environment.
• Annual renewal — SOC 2 is not a one-time expense. Reports are renewed annually, creating an ongoing cost commitment.

"The most expensive SOC 2 audit is the one you have to redo. Organizations that invest in proper readiness and choose a firm with relevant industry experience almost always spend less in total than those who chase the lowest initial quote."

— Sébastien Ruosch, CPA, Director of Auditsuisse Assurance

How to Reduce SOC 2 Costs

• Start with a readiness assessment — Identify and fix gaps before formal fieldwork begins. This reduces auditor time and avoids costly re-testing.
• Use compliance automation — Platforms that automate evidence collection and monitoring reduce internal team time and make the audit process more efficient.
• Right-size your scope — Only include the Trust Services Criteria and systems that your customers actually require. Over-scoping wastes time and money.
• Choose a firm with relevant expertise — Specialist firms understand your technology stack and can work more efficiently than generalist auditors who need to learn your environment.
• Build compliance into operations early — Organizations that embed controls into their engineering workflows from the start spend a fraction of what late-stage retrofitting costs.

What to Look For in a SOC 2 Audit Proposal

When evaluating audit proposals, consider these factors beyond the bottom-line price:

• Fixed vs hourly pricing — Fixed-fee proposals provide budget certainty. Hourly billing can escalate unpredictably.
• Auditor seniority — Senior-led engagements are more efficient and produce better outcomes than teams of junior associates.
• Communication approach — Clear expectations for responsiveness, status updates, and issue escalation.
• Post-audit support — Does the firm help you understand and remediate findings, or just hand over the report?
• AICPA peer review status — Verify the firm is enrolled in AICPA peer review. This is not optional.
