RSI offers full SRS Audit support through its Statistical Sampler system, which easily integrates with TaxMaster.

Statistical Sampler

RSI’s Statistical Sampler allows you to perform a Stratified Random Sample (SRS) audit. Its wizard-based approach guides an auditor through a step-by-step process to conduct an SRS audit.
This way, the auditor performs the audit autonomously without (or with minimal) assistance from a Computer Auditing Specialist (CAS).

To ensure all SRS audits adhere to the agency’s process and procedure, Statistical Sampler allows
administrators to establish and maintain the set of accepted sampling parameters, confidence intervals, and other options in a central location.
