What is the difference between a test of details and a substantive analytical procedure?
IntermediateAnswer
A test of details examines individual items—vouching transactions to documents, confirming balances, recalculating. A substantive analytical procedure evaluates plausibility by studying relationships among financial and non-financial data (e.g., expecting payroll to move with headcount). Tests of details give direct evidence on items; analytics give evidence about reasonableness of a total.
Real-world example The auditor estimates expected rent expense from lease terms (analytics) and also vouches selected payments to invoices (details).
