How Quality Audits Work
A typical audit begins by defining the audit scope, criteria, period, and evidence requirements. The auditor then reviews relevant policies and records, interviews process owners when appropriate, tests selected transactions or activities, and compares observed practices with established requirements.
For example, an accounts payable quality audit may trace an invoice from capture and extraction through validation, matching, approval, GL coding, and posting. The review can verify whether required information was captured accurately, whether approvals followed policy, and whether transactions reached the correct accounting records.
Audit findings are generally documented with supporting evidence, the applicable requirement, the observed condition, and the action needed to address any identified gap. Follow-up reviews can then confirm whether agreed improvements were implemented effectively.
Quality Audits Across Finance and Operations
Quality audits can connect operational controls with financial outcomes. In procure-to-pay workflows, auditors may review requisitions, the purchase order, receiving evidence, invoice matching, approval controls, and payment authorization. These checks help establish whether spending follows approved processes and whether financial records reflect the underlying transaction.
In invoice processing, audit testing can also examine whether extraction and validation results remain accurate before approval and posting. Consistent gl coding is particularly important because incorrect account classification can affect expense reporting, management analysis, and financial statements.

Key Components of a Quality Audit
A practical quality audit usually combines several evidence sources rather than relying on a single record. Important components include:
- Audit criteria: Policies, procedures, specifications, regulations, contracts, or control requirements used as the benchmark.
- Evidence: Documents, transaction records, system logs, approvals, reconciliations, and other information supporting audit conclusions.
- Sampling: A defined selection of transactions, records, or activities for detailed testing.
- Findings: Documented observations showing where actual practices align with or differ from requirements.
- Corrective actions: Specific improvements assigned to responsible owners with appropriate follow-up.
Quality Audits and Quality Controls
Quality audits are closely connected with Quality Control, but the two activities serve different purposes. Quality control focuses on checking and controlling outputs or processes during normal operations, while a quality audit evaluates whether the broader system of controls and procedures is working as intended.
A related Quality Check may occur at an individual transaction or process step, whereas an audit typically examines patterns, evidence, governance, and adherence across a defined scope. Using both approaches creates a stronger control environment because immediate checks can prevent errors while audits can identify recurring process weaknesses.
Using AI and Automation in Quality Audits
Modern audit programs can use automation to review larger data sets, identify unusual transactions, compare records against defined rules, and prioritize areas requiring human review. These capabilities can make testing more continuous and give auditors faster access to relevant evidence.
Transform Audits with AI Automation: Key Benefits & Best Practices provides an educational framework for understanding how AI can automate data analysis, identify anomalies, shorten audit cycles, and help auditors focus attention on higher-risk areas.
For finance workflows, automated audit checks can also compare invoice fields, approval records, coding decisions, and posting data. This supports consistent testing while preserving an evidence trail for review and follow-up.
Business Impact and Best Practices
Well-designed quality audits can strengthen operational discipline while improving the reliability of information used for financial decisions. Audit results can reveal recurring approval exceptions, documentation gaps, coding inconsistencies, supplier control issues, or process deviations that affect reporting quality.
For revenue-focused organizations, audit procedures can also examine whether transactions are supported by appropriate contracts, orders, delivery evidence, pricing records, and accounting entries. This connects audit evidence with Revenue Quality, helping finance and operations teams understand whether reported revenue is supported by consistent and reliable underlying processes.
Effective programs define clear audit criteria, maintain evidence standards, assign accountable owners, track corrective actions, and schedule follow-up testing. Auditors should also distinguish isolated exceptions from recurring patterns so that management can direct improvement efforts using reliable evidence.
Summary
Quality Audits provide a structured way to evaluate whether processes, controls, records, and outputs meet established requirements. By combining documented criteria, evidence-based testing, sampling, findings, and corrective actions, organizations can strengthen operational efficiency and financial reporting. When supported by automation and appropriate AI capabilities, quality audits can expand coverage, accelerate analysis, and provide more continuous visibility into process performance.
