SOC 1 Readiness Checklist
40 checks across scoping, ICFR control objectives, the AT-C 320 system-description elements, CUECs, and audit logistics — everything to verify before a CPA firm walks in.
Download Free Checklist (PDF)The SOC 1 Readiness Checklist is a free, 40-point self-assessment for service organizations preparing for a SOC 1 (SSAE 18 / AT-C section 320) examination. It walks you through the seven areas a CPA firm will actually probe — engagement scoping, the five ICFR control-objective categories, the nine required elements of the system description, control design and evidence, complementary user entity controls, the management assertion, and audit logistics — and produces a prioritized gap list. It is built for payroll, fintech, loan-servicing, BPO, and accounting-outsourcing providers whose customers' auditors are asking for a SOC 1.
What's Included
Scoping & Report Type
Which services, which period, Type 1 vs Type 2 — the questions that set the engagement's cost and effort
ICFR Control Objectives
The five control-objective categories (transaction processing, access & SoD, change management, data integrity, monitoring) as checkable items
System Description Elements
The nine elements AT-C section 320 requires in management's description, as a drafting checklist
Evidence Readiness
The four evidence types CPAs use — inquiry, inspection, observation, reperformance — and what to have on file for each control
CUECs & Subservice Organizations
Drafting genuinely necessary CUECs and choosing carve-out vs inclusive treatment for your own vendors
Assertion & Audit Logistics
Management assertion prep, PBC list, walkthrough scheduling, and bridge-letter planning for period gaps
Who This Is For
- →Payroll & HR-tech platforms whose output lands in customers' P&L
- →Fintech, payments & loan servicers processing transactions on customers' books
- →BPOs & accounting-outsourcing firms running O2C / P2P / R2R cycles for user entities

SOC 1 Readiness FAQs
What the checklist covers, who it's for, and what it can and can't promise.
How long does the SOC 1 readiness checklist take to complete?
Two to three hours for most teams. You work through 40 checks across seven areas — scoping, control objectives, the system description, control design and evidence, CUECs and subservice organizations, the management assertion, and audit logistics — and finish with a prioritized gap list you can hand to whoever owns remediation.
Is this checklist for Type 1 or Type 2 readiness?
Both. The checks cover everything a Type 1 requires (design and description), and flag the additional items a Type 2 adds — the observation period, evidence retention across the window, and interim testing. If you are new to the distinction, read our SOC 1 Type 1 vs Type 2 guide first.
Who should use this checklist?
Service organizations whose processing affects customers' financial reporting: payroll processors, fintech and payment platforms, loan and mortgage servicers, BPOs running finance cycles, and accounting-outsourcing firms. It assumes no prior SOC 1 experience and defines every term it uses.
Is the checklist really free? Do I need to give an email?
Yes, and no email required. Download it, share it internally, reuse it every cycle. If the gap list it produces looks daunting, that is the point at which a readiness consultation is worth a conversation.
Does completing the checklist mean we'll pass the SOC 1 examination?
No checklist can promise an outcome — the examination is performed by an independent CPA firm against your specific control objectives. What the checklist does is surface the gaps that most commonly become findings (segregation-of-duties failures, stale access reviews, undocumented CUECs, missing reconciliation evidence) while they are still cheap to fix.
