Evaluating a SOC 1® from Your Service Organization for Your Financial Statement Audit8 Min Read

Before you rely on a SOC 1® Report, know what it really covers

A SOC 1® report can be a valuable tool when a service organization initiates, processes, or records transactions that impact your company’s financial records. It provides insight into the service organization’s control environment and can help support the accuracy and completeness of the financial data provided to your company as part of their services.

Financial statement auditors are required to understand and evaluate controls over processes that impact the amounts and disclosures reported in the financial statements. When a company outsources part of those processes to a service organization, the auditor cannot directly test the service organization's controls. Instead, a SOC 1® report provides information about the design and operating effectiveness of those controls and can be used by management and auditors as part of their assessment of internal control over financial reporting.

However, obtaining a SOC 1® report does not automatically mean the controls at the service organization are appropriate and can be relied on.  These reports vary widely. The services, control objectives, and control activities included in the reports are defined by the service organization and are designed to meet the needs of a broad range of users. As a result, the reports may not cover processes that are critical to your company, particularly where there are unique use cases or client specific processes.

A report may appear strong but still fail to address the specific ways your company uses the provider or the risks that use creates. For that reason, you should take a structured approach before concluding that a SOC 1® report is sufficient.

Step 1: Understand the services provided

The first step is to understand and document the services relevant to your company’s internal control over financial reporting that are being provided. These include services that initiate or process transactions, perform calculations that impact financial amounts, record or maintain data used in accounting or reporting, generate reports relied on for financial reporting, or host systems used in the accounting process. Without understanding the relevant services being used, it is difficult to determine whether the SOC 1® report is relevant or sufficient.

After identifying the relevant services, you should determine how they flow through your company’s processes and affect the financial statements. This includes understanding what information is sent to the provider, what processing occurs at the provider, what reports, files, or outputs are returned, and how those outputs are used in journal entries, account reconciliations, estimates, disclosures, or other financial reporting activities.

For example, a company may outsource payroll processing to a third-party payroll provider. The company submits employee hours, compensation information, and payroll changes to the provider, which calculates gross pay, deductions, payroll taxes, and net pay. The resulting payroll reports and journal entry files are then used to record payroll expense, payroll tax liabilities, accrued compensation, and cash disbursements in the company's financial statements. Because the company relies on the provider's processing and reports, management and the external auditor may use the provider's SOC 1® report to understand and evaluate the controls supporting the accuracy and completeness of that information.

Step 2: Perform a risk assessment

With that understanding in place, your company can identify the critical risks associated with using the service organization. The focus should be on what could go wrong from a financial reporting perspective, such as incomplete or inaccurate processing, unauthorized changes to data, interface failures, missed exceptions, untimely reporting, or reports that cannot be relied upon.

Using the payroll example, risks could include inaccurate payroll calculations, unauthorized changes to employee master data, incomplete transmission of payroll information, or inaccurate reports used to record payroll-related journal entries.

Those risks are then translated into the processes and controls that are necessary to reduce the associated risks to an acceptable level. These typically include processes and controls implemented at both your company and the service provider over data input, processing accuracy, report completeness, logical access, change management, reconciliations, and exception handling.

Step 3: Review the SOC 1® Report

The first step of the report review is to confirm that the appropriate report has been obtained for review. Questions to answer to validate the appropriateness include:

• Are the services being used by your company covered by the report?
• Does the report include an opinion on the design, implementation, and operational effectiveness of the controls (Type 2 report), not just the design and implementation (Type 1 report)?
• Does the report cover a representative period of your company’s audit period?
• Was the report issued by a reputable service auditor that has experience in SOC reporting?

The next step is to evaluate the system description, control objectives, and control activities in the report to assess if they address the risks previously identified. Because these elements are defined by the service organization to meet the needs of a broad range of users, the report may not address the specific applications, transaction streams, interfaces, outputs, or processes your company relies on. Typical areas to evaluate include controls over data input, processing accuracy, report completeness and accuracy, access, change management, reconciliations, and exception handling.

You should also consider whether the service organization uses subservice organizations and, if so, whether they are included in the report or carved out. If a carved-out subservice organization performs services or controls that are critical to the organization’s financial reporting, the organization may need to obtain that subservice organization’s SOC 1® report or other evidence to complete the evaluation.

You should also give careful attention to complementary user entity controls (CUECs), which are controls the service organization had determined are necessary to be implemented at the user entity (your company) in order for the control objectives in the SOC 1® report to be achieved. You should identify which CUECs are relevant based on the specific services being used, understand what each one requires, and determine whether your company has implemented those controls and whether they are operating effectively. Relevant CUECs often relate to areas such as validating data submitted to the service provider, reviewing output reports, maintaining appropriate user access, approving transactions, and performing reconciliations. If applicable CUECs are not in place or are not operating effectively, you may not be able to rely on the service organization’s controls to the extent expected and may need additional procedures or compensating controls.

Step 4: Final analysis and conclusion

The final step is to make a practical determination about adequacy and reliance. A SOC 1® report is adequate only if it covers the right services and period, is issued by a credible service auditor, addresses the risks identified by your company, and is supported by applicable CUECs that are actually in place at your company. If those conditions are met, the report can be a strong component of your company’s control evaluation and can support the external financial statement audit.

If the SOC 1® is not adequate, you should decide whether the remaining risks can be addressed through additional controls at your company, additional procedures over the service organization, or direct testing of key reports and outputs. In some cases, stronger user-side review controls, reconciliations, or validation procedures may be enough to address the gap. In others, particularly where critical processes are outsourced and the provider cannot supply suitable evidence over its control environment, you may need to reconsider whether the service organization remains an appropriate provider. The right answer will depend on the significance of the outsourced process, the severity of the uncovered risks, and the company’s ability to implement effective compensating controls.

Ultimately, evaluating a SOC 1® is not about collecting a report for the audit file. It is about determining whether your company’s use of a service organization supports reliable financial reporting. When a company approaches the evaluation with a clear understanding of outsourced risks, report scope, service auditor quality, subservice organizations, and CUECs, they are better positioned to support both sound governance and an efficient financial statement audit.

Putting it all together

A SOC 1® report can provide meaningful assurance, but only when it is evaluated in the context of your company’s actual risks and responsibilities. Management should not view the report as a checklist item, but as one part of a broader control evaluation over outsourced financial reporting processes. By understanding what the report covers, what it excludes, and what controls must still operate within your own organization, you can strengthen audit readiness, improve governance, and reduce the risk of surprises during the financial statement audit.
