A SOC 1 report and a SOC 2 report reassure different people on the customer's side. SOC 1 addresses your controls as they affect the customer's financial reporting. SOC 2 addresses your controls against trust criteria such as security and availability. The report you need is the one matching the reviewer who keeps asking for it. Teams deciding between report types should also review the SOC 2 readiness checklist and the broader multi-jurisdiction compliance planning approach.
Quick Answer
SOC 1 and SOC 2 answer different customer concerns. SOC 1 relates to financial reporting impact; SOC 2 relates to security, availability, confidentiality, processing integrity, or privacy controls.
What a SOC 1 report covers
A SOC 1 report gives the customer's finance and audit functions a basis to rely on your service in their own financial reporting controls. It is written for an audience that speaks in journal entries, reconciliations, and period-end close.
SOC 1 fits service organizations whose work touches a customer's numbers: payroll processors, billing platforms, payment facilitators, fund administrators, claims administrators. If an error on your side could cause the customer to misstate an account balance or a financial statement line, their auditors will want assurance over your controls, and that assurance arrives as a SOC 1 report. The customer's external auditor reads the report to decide how much they can rely on your service when auditing the customer's books.
What a SOC 2 report covers
A SOC 2 report gives the customer's security, risk, and procurement functions evidence that your controls hold up against trust services criteria.
The reviewer is rarely an accountant. It is a security analyst, a vendor risk manager, or a procurement lead working through due diligence. The criteria cover areas such as security, availability, processing integrity, confidentiality, and privacy, and which criteria appear depends on your services and what you commit to in the report's scope.
SOC 2 fits organizations whose work touches a customer's data or the systems that deliver their service: SaaS platforms, cloud infrastructure providers, managed security providers, and providers handling customer data of almost any kind. The question behind the request is not "will this break the customer's books" but "can we trust this provider with our data and our operations."
The two reports side by side
| SOC 1 | SOC 2 | |
|---|---|---|
| Core question | Could your service misstate the customer's financial reporting? | Can the customer trust your controls with their data and operations? |
| Customer reviewer | Finance, controllership, external auditor | Security, vendor risk, procurement |
| Scope basis | Controls relevant to financial reporting | Trust services criteria (security, availability, processing integrity, confidentiality, privacy) |
| Typical buyer fit | Payroll, billing, payment, fund admin, claims processing | SaaS, cloud, managed services, data processing |
| How it gets requested | During financial audit planning or a finance-led vendor review | During security review or vendor onboarding |
Why the customer's reviewer, not your product, decides the answer
Which report a customer asks for follows from what your service does to them, and the person who asks tells you which one it is. The request itself is often ambiguous; the reviewer's follow-up questions usually are not.
A prospect whose security team sends a questionnaire is running a SOC 2 review. A prospect whose controller calls about how you reconcile transactions is running a SOC 1 conversation.
Teams get this wrong in both directions. A payroll platform that pursues only SOC 2 finds that security questionnaires keep asking about financial reporting controls it did not scope. A provider that handles customer data and pursues only SOC 1 finds that procurement will not open the conversation without a SOC 2. Neither report is the prestige option. They answer different questions, and a customer satisfied with one will still ask for the other if their question changed.
The pattern to watch: requests that arrive through your finance contacts, during contract renewal tied to billing accuracy, or from customers in regulated industries with financial reporting obligations point at SOC 1. Requests that arrive through a vendor security questionnaire, a trust center review, or an onboarding checklist point at SOC 2. If you see both kinds, confirm each request before planning either engagement.
Type 1 and Type 2 are a second decision, not a second report
Within either report type, the customer may specify whether they want a point-in-time view or evidence that the controls operated over time. That is the Type 1 versus Type 2 distinction, and it applies to both.
| Type 1 | Type 2 | |
|---|---|---|
| What it addresses | Whether controls are designed suitably at a point in time | Whether those controls also operated effectively across an observation period |
| What the customer learns | The design exists on paper | The design exists and held up in practice |
| Planning question | Does the requester accept this report type? | Which period and scope does the requester need? |
| Planning focus | Confirm the point-in-time scope | Confirm the period, evidence, and reporting schedule |
A Type 1 report tells a customer you built the controls. A Type 2 tells them the controls survived contact with daily operations. Vendor risk teams that have been burned by well-documented controls that nobody runs may ask for Type 2, and teams evaluating a young vendor sometimes accept Type 1 as an interim step while the observation period runs.
How to decide what to pursue first
- List who has asked and what they asked behind the question. Sort your last several report requests by reviewer function. Finance and audit contacts point to SOC 1; security and procurement contacts point to SOC 2.
- Map your service against the customer's exposure. If an error on your side distorts their financial statements, SOC 1 belongs in your plan. If an incident on your side compromises their data or availability, SOC 2 does. Many services carry both exposures.
- Check your largest deals in the pipeline. The contract you most want tends to name the report. A security exhibit referencing trust criteria is a SOC 2 request. A due diligence section referencing the customer's financial controls is a SOC 1 request.
- Start with the report your pipeline asks for, then add the other. Planning both together can add preparation work. Sequencing them lets evidence collection for one inform the other, which is where the real savings sit.
Sequencing matters more than doing both at once. The two reports overlap in practice more than their scopes suggest.
Access reviews, change management, vendor management, and incident handling appear in both conversations. Teams that map their controls once and assemble each report from the same evidence base stop treating the second report as a second project. See evidence reuse across jurisdictions and frameworks for how that mapping works.
Getting through the audit without scrambling
Preparation looks similar whichever report you pursue: scope agreed with the auditor, evidence collected, exceptions documented early, and management responses written by the people who run the controls.
A compliance audit preparation routine covers the mechanics that keep either engagement from becoming a fire drill, and the SOC 2 readiness checklist is the starting point for teams whose next request points that way.
One boundary worth stating plainly. Your auditor issues the report; the customer's auditor decides how to use it. You cannot control the opinion, and you should not promise customers a clean one. What you control is the state of your evidence going in, and whether the customer's reviewers can trace claims back to records. For teams using AI tools anywhere in that preparation, what makes AI-assisted work credible to an auditor covers the traceability question that comes up in both SOC 1 and SOC 2 reviews.
FAQ
Can one report substitute for the other? No. A SOC 2 report does not address the customer's financial reporting concerns, and a SOC 1 report does not address security and availability criteria. A customer asking for one and receiving the other may send a follow-up request for the missing report.
Do we need both at the same time? Not necessarily. Start with the report your revenue depends on. Teams commonly add the second report once customer requests justify the audit cost, or once one report's evidence collection is mature enough that the second adds preparation rather than starting from zero.
What if a customer asks for "a SOC report" without specifying? Ask which function is reviewing the report and what question they need it to answer. The reviewer's function resolves the ambiguity in one question, and asking it saves both sides a review cycle.
Does a Type 1 report satisfy a customer asking for Type 2? Only as an interim step, and only if the customer agrees to it. A Type 1 shows design at a point in time; customers asking for Type 2 usually want evidence of operation across a period. Some vendor review processes accept a Type 1 with a commitment to provide the Type 2 when the observation period completes.
We only sell to other businesses. Doesn't that mean SOC 2? It depends on what your service does to the customer, not the fact that they are a business. If your work touches their data and systems, SOC 2 is the expected request. If your work touches their numbers, SOC 1 requests follow, even from business customers.
