SOC 1 attestation in Seattle at a glance
A SOC 1 report matters in Seattle to the businesses whose software or service ends up inside somebody else's accounts. Payroll and billing platforms, payment processors, subscription-revenue engines and outsourced finance providers run controls that their customers' auditors must rely on. A licensed CPA firm examines those controls and issues a SOC 1 report, with Type 1 covering design at a point in time and Type 2 covering operation across a period. It is an attestation under accounting standards rather than an ISO certificate, and Sterling does not issue it. Sterling prepares the service organisation with scope, control objectives and evidence, working with Seattle teams from its New York office.

SOC 1 in Seattle: questions clients ask
Which Seattle companies usually need a SOC 1 report?
Service organisations whose work touches customers' financial reporting: payroll and billing providers, payment processors, outsourced finance functions and some software that calculates revenue or fees. Customers' auditors normally request it. Ask which report your customers' auditors expect. Do not assume that a SOC 2 report will satisfy them.
Who is responsible for the SOC 1 opinion?
A licensed CPA firm examines the controls and issues the report. The service organisation owns its control descriptions and the controls themselves. Sterling does not attest, but prepares the organisation so the examination runs smoothly and findings are fewer. Early rehearsal also reduces surprises during testing.
