Every cost range on SOC 2 audit cost traces back to one of the entries below. Each entry carries its calculation method, the source URL where one exists, and the date we last refreshed it. Audit fees move; we keep these dated so a reader can judge how recent the data is.
The four-tier evidence-weighting model behind these entries is documented in our methodology at /methodology/#source-tiers. Verification cadence triggers at /methodology/#verification-cadence.
