Complete audit
In one sentenceAn audit in which the auditor examines all transactions and documents recorded during the period without relying on a sample.
Simply put
In a complete audit every entry and every document is examined. It suits very small businesses or a specific high-risk item, such as a cash box suspected of embezzlement.
In large businesses it becomes costly and slow, which is why auditors usually turn to test-check audits using samples.
Example
A small establishment issued only 300 payment vouchers during the year, and doubts arose about its petty expenses, so the auditor decided to examine all three hundred vouchers instead of taking a sample.
Don't confuse it with
Test-check auditA test-check audit examines a selected sample and then generalizes the result, while a complete audit examines everything.
