40-Point Audit Firm Evaluation Checklist
Score audit firms on team stability, fee predictability, technical expertise, and PCAOB inspection history. Surface bait-and-switch staffing and change order patterns before you sign.
Scoring Framework
Rate each answer 1 to 5 based on specificity and supporting documentation. Firms that consistently score below the midpoint tend to generate meaningfully more surprise costs and timeline delays, usually because the gaps in team transparency, fee detail, or technical bench compound across an engagement year.
Evaluation Criteria
