SOC 2 Type 1 vs Type 2: Differences, Costs, and When to Choose Each

Most of our customers skip Type 1 entirely. Below we explain when the exception applies, but our default recommendation is to start the Type 2 observation window now and use a CPA attestation letter for any prospect who needs proof you're in audit. Read the full reasoning ->

For seed-stage startups especially, the cost of two audits (Type 1 + Type 2) rarely makes sense when one audit closes the same deals.

The fundamental difference is simple:

SOC 2 Type 1 evaluates the design of your controls at a specific point in time. The auditor asks: "Are these controls properly designed to meet the Trust Services Criteria?"

SOC 2 Type 2 evaluates the operating effectiveness of your controls over a period of time (typically 3-12 months). The auditor asks: "Are these controls not only well-designed but actually working consistently?"

Think of it this way: Type 1 is a snapshot. Type 2 is a movie. Type 1 says you have good controls on paper. Type 2 proves you actually follow them.

What the auditor evaluates: The design and implementation of your controls at a single point in time. They review your policies, configurations, and procedures to determine if they are suitably designed to meet the selected Trust Services Criteria.

What you need to prepare: Written policies (information security, access control, change management, incident response, etc.), documentation of your system architecture, evidence that controls are in place (not just planned).

Timeline: 4-8 weeks for the audit itself, after your controls are ready.

Cost: Typically $15,000-$20,000 for startups and small companies. Remember that a Type 1 is an extra audit if you also need Type 2 later - most of our customers skip it.

When Type 1 makes sense: You need a SOC 2 report quickly to close a deal. You are early in your compliance journey and want to establish a baseline. Your customers accept Type 1 reports. You want to validate your control design before committing to a Type 2 observation period.

What the auditor evaluates: The operating effectiveness of your controls over a defined period. The auditor selects samples from the observation period and tests whether controls were consistently applied. For example, they might check if access reviews were actually performed quarterly, if change management procedures were followed for all deployments, and if incidents were properly logged and responded to.

What you need to prepare: Everything from Type 1, plus evidence that controls operated consistently throughout the observation period. This means logs, review records, incident reports, change tickets, and other artifacts generated during normal operations.

Observation period: Typically 3, 6, or 12 months. Most companies start with 3 or 6 months for their first Type 2. Between reports, a bridge letter from your management covers the gap.

Timeline: The observation period plus 4-8 weeks for the audit.

Cost: Quotes run $7,000-$25,000 for a security-only audit at startups and small companies, but a 3-month observation period, Security-only scope, and a peer-reviewed boutique CPA firm lands a first Type 2 at $5,000-$8,000; mid-size companies up to ~300 employees run $25,000-$36,000. Budget separately for the annual penetration test and tabletop exercises auditors typically expect - a traditional pen test runs $7,000-$10,000 and each tabletop was a separate facilitated engagement, though agentic pen tests now start at $99 through SimpleAudit partners and tabletop exercises are included in SimpleAudit's Prove plan - see the full cost breakdown.

When Type 2 makes sense: Enterprise customers require it (most do). You want to demonstrate operational maturity. You have already completed a Type 1 and are ready to demonstrate sustained compliance. Your competitors have Type 2 reports. For Series A companies entering enterprise sales, Type 2 is effectively table stakes.

Most companies follow this progression:

Weeks 1–10: Build your compliance program. Write policies, implement controls, set up monitoring. Tools like SimpleAudit accelerate this phase with AI-generated policies and risk assessments: most teams reach audit-ready in 4–10 weeks depending on starting maturity, rather than several months.

After build: Type 1 audit (if you do one). Validate that your controls are properly designed and fix any issues the auditor identifies.

Then: Type 2 observation period: operate your controls consistently and collect evidence continuously. Most companies use a 3–6 month window.

After the window: Type 2 audit. The auditor tests your controls from the observation period.

After that: Annual Type 2 renewals. The second year is significantly easier because your controls are established and evidence collection is routine.

Some companies skip Type 1 entirely and go straight to Type 2 if they have time. This saves money on one audit cycle but means waiting longer for your first report.

Choose Type 1 if: You have a deal that requires SOC 2 urgently (next 2-3 months). Your customers explicitly accept Type 1 reports. You are new to SOC 2 and want to validate your approach before the longer Type 2 commitment.

Choose Type 2 (skip Type 1) if: You do not need a report in under about 3 months, so a 3-month observation window fits your timeline. Your target customers will only accept Type 2 (most enterprise companies). You want to save money by doing one audit instead of two. You are confident in your controls and want to demonstrate maturity from the start.

Choose Type 1 then Type 2 if: You need a report in the short term but know Type 2 will be required eventually. You want the auditor feedback from Type 1 to improve controls before the longer Type 2 observation. You are building credibility incrementally with customers.

Starting the observation period before controls are ready: If your controls are not consistently operating when the observation period begins, the auditor will find exceptions. Fix issues before you start the clock.

Not collecting evidence continuously: Do not wait until the audit to gather evidence. Set up automated evidence collection or schedule monthly evidence reviews. Missing evidence for a control means the auditor cannot verify it operated.

Underestimating the people cost: SOC 2 is not just a technical exercise. Someone needs to own the program, coordinate with the auditor, respond to evidence requests, and maintain controls. Budget real time for this.

Choosing the wrong auditor: Not all auditors are created equal. Choose one experienced with companies your size. An auditor used to Fortune 500 companies may not understand startup constraints. Ask for references from similar companies, and see how to choose a SOC 2 auditor for what else to check.

Ignoring remediation items: Type 1 auditors often identify improvements. Address these before starting your Type 2 observation period. Carrying known issues into Type 2 leads to exceptions in your report.
