An audit checklist is a tool used to ensure a systematic and comprehensive approach to the audit process. It typically includes reviewing financial statements, verifying the accuracy of financial records, assessing compliance with accounting principles and regulations, evaluating internal controls, analyzing supporting documentation, conducting tests and sampling, and documenting audit findings. The checklist may also encompass organizational charts, personnel manuals, major contracts, and investment summaries. However, the specific items on the checklist may vary based on the nature of the audit, industry-specific requirements, and the organization's unique circumstances.
