What audit types do you support?

Financial statement audits, reviews, compilations, single audits (Uniform Guidance), employee benefit plan audits, SOC engagements, and Yellow Book audits.

Do you sign or issue audit reports?

No. We're not the auditor of record. We provide the support workpapers and documentation. Your firm keeps all professional responsibility and signs the report.

How do you handle independence?

We work as an extension of your audit staff, follow your firm's independence procedures, and never hold a financial interest in a client engagement.

Which audit methodologies are you trained in?

AICPA, PCAOB, Yellow Book / GAGAS, and Uniform Guidance. We work in CCH ProSystem fx, Caseware, PPC Smart Practice Aids, and TeamMate.

Can you support PCAOB audits?

We support the documentation for PCAOB engagements, though we recommend the final review and judgment-based areas stay with your in-house team.

How is data security handled?

Signed NDAs, encrypted transfer, role-based access, and SOC-aligned data handling. No client data ever sits on a local device.

What does the pilot include?

A single, no-risk engagement where we deliver real PBC schedules and workpapers. You judge the format, indexing, and turnaround before committing.
