What does an internal audit cover?

Short answerAn internal audit reviews processes, internal controls and risks across the business — typically procurement and payments, inventory, sales and receivables, payroll, statutory compliance, and IT controls. It tests whether policies are followed, finds leakages or fraud risks, and recommends fixes. The scope is set by management based on the business’s risk areas.

The typical coverage

An internal audit ranges across the operating cycle: procurement and vendor payments, inventory and stores, sales, billing and receivables, payroll, cash and bank, statutory compliance (GST, TDS, labour), and increasingly IT and access controls. The aim is to check that the controls actually operate, not just that they exist on paper.

Risk-based and tailored

The scope is set by management (or the audit committee), focused on the company’s highest-risk areas — a manufacturer emphasises inventory and procurement; a services firm emphasises billing and payroll. It tests samples, traces transactions, and looks for leakages, policy breaches and fraud indicators. A formal audit plan should define the cycle and coverage.

A worked example

Example: an internal audit of a retailer’s procurement samples 50 purchase orders and finds several placed without the required quotes, and stock differences in two stores — pointing to a control gap and possible pilferage. Management tightens the approval workflow and stock counts. That is how internal audit adds value — catching issues a year-end audit wouldn’t. Our team can scope and run it.
