What is an Audit SOP?
An audit SOP is a formal standard operating procedure spelling out how your organization actually conducts audits. It walks through each stage of the process, starting with planning and moving through to final reporting and follow-up. Here's the thing: without a standardized approach, audits can vary dramatically in quality. One auditor might catch a critical issue that another completely overlooks, and comparing results across different audits or time periods becomes nearly impossible.
That's really what audit standard operating procedures are meant to solve. When everyone follows the same methodology, results become reliable. Auditors understand what they're looking for, how to document what they find, and what happens after. Organizations can actually trust their audit outcomes and use them to make real improvements.
Key Characteristics of Audit SOPs
- Step-by-Step Methodology: Covers audit planning, preparation, execution, reporting, and follow-up in a clear sequence
- Documentation Requirements: Specifies what records need to be kept, including audit plans, evidence, findings, and corrective actions
- Auditor Qualifications: Defines who can conduct audits and what training or experience they should have
- Independence Standards: Makes sure auditors stay objective and free from conflicts of interest
- Evidence Collection Guidelines: Details how to gather, verify, and document audit evidence
Audit SOP Examples
Example 1: Financial Internal Audit
A manufacturing company might have an internal audit SOP specifying quarterly reviews of financial controls. The procedure guides auditors through sampling methodology for transaction testing, documentation standards for workpapers, escalation paths when significant findings come up, and timeline requirements for management responses. Each audit follows identical steps regardless of who's conducting it.
Example 2: Quality Management System Audit
Consider a pharmaceutical company running ISO 9001 compliance audits. Their audit SOP details pre-audit preparation (reviewing previous findings, scheduling interviews), fieldwork execution (observation techniques, evidence requirements), and post-audit activities (tracking corrective actions, verifying fixes). The SOP ensures every quality audit meets regulatory expectations.
Audit SOP vs Compliance Manual
Both documents support organizational governance, but they serve pretty different purposes. Your compliance manual tells you what rules to follow, while your audit SOP tells you how to verify those rules are being followed.
| Aspect | Audit SOP | Compliance Manual |
|---|---|---|
| Purpose | Guides how to conduct audits | Lists what rules must be followed |
| Focus | Process and methodology | Requirements and policies |
| Audience | Auditors and audit teams | All employees |
| Updates | When audit processes change | When regulations change |
How Glitter AI Helps with Audit SOPs
Putting together an audit SOP from scratch can be time-consuming. Glitter AI speeds things up by letting you record audit procedures as you perform them, then automatically generates documented steps with screenshots and clear instructions. When internal audit procedures need updating because of regulatory changes or internal improvements, you can revise documentation in minutes instead of hours.
Visual documentation proves especially useful for audit process documentation because it removes ambiguity. Auditors see exactly which screens to check, what evidence to capture, and how to document their work. That kind of consistency is what makes audit trails reliable and keeps your organization ready for external review.

What should be included in an audit SOP?
An audit SOP should cover audit planning steps, execution methodology, documentation requirements, evidence collection procedures, reporting templates, follow-up processes, and auditor qualification standards.
Why are audit standard operating procedures important?
Audit SOPs eliminate inconsistency between auditors, help meet regulatory requirements, produce reliable and comparable results, and provide clear guidance making audits more efficient.
How often should audit SOPs be reviewed?
Audit SOPs should be reviewed at least annually, or whenever significant regulatory changes occur, processes are modified, or audit findings reveal procedural gaps.
Who is responsible for creating audit SOPs?
Internal audit managers or quality managers typically own audit SOPs. They collaborate with subject matter experts, compliance officers, and experienced auditors to develop thorough procedures.
What is the difference between internal audit procedures and external audit procedures?
Internal audit procedures are designed by the organization for its own use, focusing on operational improvement. External audit procedures follow standards set by regulators or accounting bodies, focusing on independent verification.

Yes, well-designed audit SOPs make sure audits meet regulatory standards, maintain proper documentation for regulators, and show that the organization takes compliance seriously through systematic verification.
How do you train employees on audit SOPs?
