SOC 2 timeline for a Series A startup, with the math

The first SOC 2 typically lands on a Series A engineering team because an enterprise prospect asked for it. Sometimes the deal is on the line, sometimes it is six months out. Either way the question is the same: how long does this actually take.

The answer most consultants give is shaped by their billing model, not your reality. Here is the honest version, with the variables that move the timeline by weeks.

Type 1 in six to ten weeks

SOC 2 Type 1 is a point-in-time auditor opinion on whether controls are designed to meet the AICPA Trust Services Criteria. For a small SaaS team with reasonable existing controls, six to ten weeks from kickoff to issued report is realistic. The breakdown:

• Week 1. Gap assessment, audit firm selection, scope definition. The auditor needs to be booked first; CPA firms typically have a six- to ten-week lead time on Type 1 engagements.
• Weeks 2 to 4. Policy and technical baseline. Information security policy, acceptable use, change management, vendor management. Stand up SSO if missing, deploy MDM, configure centralized logging.
• Weeks 4 to 6. Evidence collection. Access reviews, change tickets, incident logs, vendor due diligence records.
• Weeks 7 to 10. Auditor fieldwork. Walkthroughs, evidence sampling, draft report, remediation of any findings, final report.

What slips the timeline

Type 1 timelines slip on five things, in roughly this order of frequency:

1. No SSO. Adding SSO mid-engagement adds two to three weeks for procurement, configuration, and migration. Auditors expect SSO for production access; Google Workspace passwords plus 2FA on individual apps does not satisfy access management criteria for most enterprise customers.
2. No MDM. Endpoint compliance is part of the Security criterion. A bring-your-own-Mac fleet without MDM is a finding. Rolling out MDM to existing devices, even with a well-run program, takes ten to fourteen days.
3. Ad-hoc change management. Direct production deploys without ticket or peer review fail change management criteria. Implementing branch protection, requiring code review, and tying deploys to Linear or Jira tickets is straightforward but takes a week or two of process change.
4. No access reviews. Quarterly access reviews on production and sensitive systems are an expected control. Setting up the review process and running the first one takes a week.
5. No incident response runbook. A documented runbook with severity levels and a recent tabletop exercise satisfies most audit asks. Writing one and running a tabletop is a half-day exercise but it has to actually happen.

Type 2 needs an observation window

Type 2 is the report enterprise procurement actually wants to see. It is an opinion that controls operated effectively over an observation window of three to twelve months. Three months is the minimum; six is more common. The window starts after Type 1 and runs continuously.

A practical sequencing:

• Type 1 issued at month three.
• Three- or six-month observation window runs during the period the controls operate.
• Type 2 fieldwork begins immediately after the window closes.
• Type 2 report typically issued four to eight weeks after fieldwork begins.

From kickoff to a Type 2 report in hand, plan on seven to twelve months total. Customers tend to accept the Type 1 plus an explicit Type 2 timeline as a sales artifact during the gap.

Where engineering hours actually go

The least-discussed part of the SOC 2 timeline is the engineering opportunity cost. A typical Series A team without compliance support spends two to three engineering months on a first SOC 2: one engineer mostly full-time, plus partial time from senior engineers reviewing policies and signing off on technical controls.

Most of that time is not deep work. It is filling spreadsheets, gathering evidence, writing policies that should not require an engineer, and chasing down screenshots. The remediation work itself, when scoped, is closer to two to three weeks of focused engineering.

The reason HSD exists is that the spreadsheet work is exactly the work compliance engineers should be doing instead of product engineers. See our SOC 2 service for the version where this is not your engineers' problem.

What auditors will actually check

SOC 2 Type 1 fieldwork is lighter than people expect. The auditor will:

• Read your information security policy and other relevant policies.
• Walk through change management with an engineer who actually deploys.
• Sample a handful of access reviews, change tickets, and onboarding records.
• Confirm endpoint controls (MDM enforcement, encryption, screen lock).
• Verify backup and recovery configuration.
• Inspect logging and monitoring setup.
• Review your vendor management list.

Most fieldwork happens over Zoom in two or three sessions plus follow-up document requests. The customer-facing engineering team can usually carve out a couple of focused mornings rather than dedicating weeks.

Picking the audit firm

Audit firm choice matters more than first-time buyers expect. Two considerations:

1. Partner-tier matters. Big-four firms have name recognition; smaller firms have more flexibility on timeline and pricing. Mid-tier firms (BDO, Crowe, RSM, Schellman, Coalfire, A-LIGN) hit a sweet spot for most Series A companies.
2. Some enterprise customers reject reports from very small firms. If your target customer is a Fortune 500 company, ask which auditors they accept. The answer is usually any firm with an active AICPA peer review and a solid quality program.

The Type 1 sales artifact gap

Between Type 1 issuance and Type 2 issuance, customers may ask for a bridge letter or a customer letter. The auditor or the service organization can issue these to address the period between the report end date and the customer reliance date. They are routine; if you anticipate the request, agree the form with your audit firm at engagement letter signing.

The honest summary

Six to ten weeks for Type 1, then a three- or six-month observation window, then four to eight weeks for Type 2. Total: seven to twelve months from kickoff to a Type 2 report you can hand to enterprise procurement. Most of the variability is in your existing control posture, not in the audit process itself.

The fastest path is to address SSO, MDM, change management, access reviews, and incident response before kickoff, not during. The slowest path is buying compliance software and treating its dashboard as the program. The dashboard does not configure SSO or roll out MDM; engineers do.
