Service Organizations: Applying SSAE No. 16, Reporting on Controls at a Service Organization Guide (SOC 1)
Guide: This guide is for CPAs reporting on controls at a service organization that affect user entities’ internal control over financial reporting. It is designed to assist CPAs in transitioning from performing a service auditor’s engagement under Statement on Auditing Standards (SAS) No. 70, Service Organizations, to doing so under Statement on Standards for Attestation Engagements (SSAE) No. 16, Reporting on Controls at a Service Organization, which replaces the guidance for service auditors in SAS No. 70
