SOC 2 Type II for a 50-person services firm: what 12 months actually costs

You'll learn

• The real line-item cost of SOC 2 Type II in 2026 (auditor fees, tool stack, engineering hours) so your CFO knows what to reserve.
• The four phases of the engagement and how long each realistically takes.
• Which controls consume 80% of the work so you can prep them first.

Why this matters

SOC 2 has moved from a nice-to-have to a deal-blocker. Over the last two years we've watched clients lose RFPs because their SOC 2 Type I (point-in-time) wasn't enough and the buyer's procurement team wouldn't consider a vendor without Type II (operating over time). The fastest-growing segment asking for Type II isn't the Fortune 500 — it's mid-market buyers with their own SOC 2, whose auditors now require vendor attestation.

The problem is most guidance on the internet treats SOC 2 like a product you buy from Vanta or Drata. You don't. You buy tooling and methodology from those platforms; the actual work is internal (or delegated to your MSP) and it takes real time. Firms that budget $50k and six months show up to the audit underprepared. This guide is what we tell clients when they ask "what is this actually going to cost us, honestly."

What SOC 2 Type II actually is

Five Trust Services Criteria you can be audited against: Security, Availability, Processing Integrity, Confidentiality, Privacy. Security is mandatory; the other four are optional scope. For a services firm with no customer-controlled infrastructure, scope is usually Security + Confidentiality + Availability — the "default three."

• Type I: a point-in-time snapshot. "On March 31, these controls existed." Easier, cheaper, less trusted. Most buyers require Type II.
• Type II: an operating-effectiveness audit over a window (typically 6 or 12 months). The auditor samples actual evidence across the window. This is what deal reviewers want to see.

The four phases

Phase 1 — Readiness / gap assessment (months 1-3)

An auditor or a competent MSP maps your current environment against the control set. You get a list of controls you already operate, controls that exist but aren't documented, and controls you don't have at all.

Typical first-pass findings in a 50-person services firm:

• Access reviews exist informally but aren't documented. The first real process change.
• Change management exists via git + PR reviews but isn't framed as a control. Usually fine once evidenced.
• Vendor management almost never exists at SOC 2 scope. This is the longest-tail item.
• Incident response exists in someone's head. Writing it down is the work.
• Encryption-at-rest on laptops and databases — probably on, probably not evidenced.
• MFA coverage on admin accounts — see Volume 1.

Phase 2 — Remediation (months 3-6)

Close the gaps. This is where most time + cost goes. Specifically:

• Documentation sprints. Write the policies, publish them, get them signed. Often 15-20 policies.
• Tool deployments. Usually one SOC 2 automation platform (Vanta, Drata, Secureframe), one SIEM or logging platform, one access-review tool.
• Control operationalization. Monthly/quarterly processes need to start actually running so the audit window has evidence to sample.

Phase 3 — Observation window (months 6-12)

The audit window. Controls need to operate continuously. You're running access reviews monthly, change approvals through the PR process, incident response drills quarterly. The audit platform (Vanta / Drata) is collecting evidence in the background.

This is the phase where discipline matters more than effort. If you skip a month of access reviews during the observation window, you either extend the window or get a qualified opinion. Neither is what buyers want to see.

Phase 4 — The actual audit (2-6 weeks at window end)

The auditor samples evidence across the window: pulls 25 random changes and checks they were approved, pulls 3 months of access reviews and checks they were completed, reviews incident logs. Then they write the report. Your team spends 20-40 hours answering questions and producing evidence.

Report delivered 2-6 weeks after fieldwork ends. Valid for 12 months from the window end date — meaning you start the next window the month after.

What it actually costs

Based on four 50-person services firm engagements we've completed in 2025-2026:

Auditor fees: $30-50k year one

• Top-tier accounting firm (Big Four / second-tier national): $45-70k.
• Mid-tier CPA firm with SOC 2 practice: $30-45k.
• Boutique / online-first auditor (A-LIGN, Schellman, Prescient Assurance): $25-35k.

For a first-time Type II audit, we usually recommend the mid-tier option. The boutiques move fast but can be inflexible on scope; the top-tier brings weight but at double the price.

Year-two audit fees drop 20-30% because the auditor already knows your environment.

Tooling: $15-30k/year ongoing

Typical stack:

• SOC 2 automation (Vanta / Drata / Secureframe): $8-15k/year.
• SIEM or logging (Datadog / Sentinel / elastic): $3-8k/year at 50-person scale.
• Access review / IAM governance: often bundled with the SOC 2 platform; $0-5k if standalone.
• Endpoint management (JAMF / Intune / Kandji): usually already budgeted, but needs to be capable of enforcing encryption + evidence.

Internal or MSP engineering time: $30-50k year one

The largest and most-understated cost. Expect:

• Readiness assessment + remediation: 150-250 engineering hours.
• Policy drafting: 60-100 hours across a mix of security, HR, engineering.
• Observation window maintenance: 4-8 hours/month for 6-12 months.
• Audit support: 20-40 hours in the final 2-4 weeks.

At a blended $150-200/hour, that's $30-50k. If you run this entirely internally with a CISO-adjacent hire, it absorbs into headcount; if you outsource to an MSP, it's a billable line item.

Total year one: $75-125k

Plus the time + opportunity cost of whoever is the internal sponsor. That role (usually called "SOC 2 owner") typically spends 15-25% of their time for the full 12 months.

The controls that consume 80% of the work

From four actual engagements, the Pareto view:

1. Access control (25% of effort). User provisioning, access reviews, least-privilege, MFA, break-glass, role-based access. See Vol 1. If your environment is scattered across 15 SaaS tools and nobody documented who has admin on any of them, this is a real project.

2. Change management (15%). Every production change needs to be reviewed and documented. Usually lands on git + PR process for code; harder for infrastructure changes and SaaS config.

3. Incident response (15%). Writing the runbook, rehearsing it in tabletop exercises, keeping the on-call rotation documented. This is a real operational capability, not a document.

4. Vendor management (10%). The vendor inventory with SOC 2 or equivalent attestation for each one. Gets painful when you find your CRM doesn't have a SOC 2 report you can request.

5. Risk assessment (10%). Annual written risk assessment. Most firms don't have one; writing the first one is a 2-week project.

6. Everything else (25%). Physical security (minimal if you're cloud-first), BCP/DR, HR background checks, security awareness training, vulnerability management, data classification, encryption evidencing.

The mistakes we see most often

1. Budgeting for auditor + tool only. The engineering hours are half the cost. If you don't reserve them, they show up anyway as missed deadlines or compressed scope.

2. Picking the wrong auditor for the wrong reason. A Big Four firm on your SOC 2 report reads great in RFPs, but if your target buyers are mid-market SaaS, a mid-tier or boutique auditor is the same signal at half the price.

3. Treating Vanta/Drata as the program. The platform automates evidence collection and documents the policies. It does not operate the controls. Buying the tool and thinking you're done is how firms show up to month 6 with nothing actually running.

4. Starting the observation window too early. If your remediation isn't complete by the window start date, the audit sample will include the pre-remediation period and you'll get findings. Better to slip the start by a month than finish with qualified opinion.

5. Shrinking scope to pass faster. Dropping Confidentiality or Availability to simplify the audit usually means re-adding them in year two when a buyer asks. The incremental effort to include them in year one is smaller than you'd think.

If you want help with this

We run SOC 2 programs for clients both as an outsourced capability and as a guided-internal engagement. The engineer who drives the program is the same one who attends your audit. If you'd like to scope what this looks like for your environment, the free IT health check includes a SOC 2 readiness pass — gap estimate, timeline, cost range. No sales pitch.
