SOC 2 audit cost: what mid-market actually pays in 2026

The breakdown most firms don't show you

The auditor's quote is the smaller part. Here's what mid-market actually pays end-to-end:

• Readiness assessment + program build: $40K-$120K fixed-fee for an early-stage SaaS, $80K-$200K for a 100-300 employee firm with multi-product scope.
• Auditor (CPA firm) fee: $20K-$80K for the Type 2 audit itself. A&Q firms (A-LIGN, Schellman, Coalfire, BDO) at the top of the band; smaller boutique CPAs at the floor.
• GRC tooling: $15K-$40K/year (Vanta, Drata, Secureframe, Sprinto). Frequently bundled into the readiness fee.
• Remediation:$0-$100K depending on what the readiness assessment finds. Encryption-at-rest gaps, MFA-not-everywhere, vendor risk programs missing — these add up.
• Year 2+ sustainment: $30K-$80K/year for evidence collection + auditor coordination + Type 2 surveillance.

Why the spread is so wide

1. TSC scope. Security is mandatory. Adding Availability, Confidentiality, Processing Integrity, or Privacy each adds 20-40% to audit fees and remediation.
2. Controls maturity. Firms with documented programs land at the floor. Firms doing security-by-tribal-knowledge land at the ceiling.
3. Auditor brand. A-LIGN and Schellman command a 30-50% premium over boutique CPA firms but produce reports that bigger customers accept without negotiation.
4. Sub-service organizations. If you run on AWS or Azure and inherit their SOC 2 reports, your audit gets simpler. If you run on infrastructure that doesn't have a SOC 2 report, your audit gets more expensive.

The mistake that costs the most money

Engaging the auditor before the readiness work is done. The auditor finds gaps, you stop the audit, you do remediation, the auditor re-engages at a higher rate. Add ~$40K to the bill plus 3-6 months of slipped timeline.

We do the inverse: auditor under contract before readiness work begins. We map the scope to their TSC interpretation. The Type 2 observation period starts on a known date with no surprises mid-fieldwork.

SOC 2 + ISO 27001 in parallel

SOC 2 and ISO 27001 share about 80% of evidence. Running them in parallel adds 20-30% to a single-framework cost but gives you both certifications at the end. For SaaS firms selling internationally, this is almost always the right call.

Add NIST AI RMF and ISO 42001 if you're shipping AI features. They share 70% of evidence with each other and ~40% with SOC 2. Document once, certify four times. See the compliance hub.

Inside the partnership

Inside a $500K-$3M Modernization Partnership, SOC 2 (and ISO 27001, NIST 800-171, HIPAA, ISO 42001 where relevant) is bundled at no separate line item. Continuous evidence collection comes free with the MSSP layer. Your auditor gets a refreshed evidence package every quarter.
