How would you design and perform sampling for testing accounts receivable in a year-end audit of an Italian SME?
Junior auditors must be able to select and execute appropriate sampling procedures so that conclusions about account balances are reliable. In Italy, understanding materiality thresholds, commercial practices and local accounting (Italian GAAP or IFRS adoption) affects sampling strategy for SMEs.
How to answer
- State the audit objective clearly (e.g., confirm existence and valuation of receivables).
- Explain your approach to determining materiality and tolerable misstatement for the accounts receivable balance, referencing firm guidance or risk assessment.
- Describe the sampling method you would choose (statistical vs non-statistical) and justify it based on risk, population size and resources.
- Specify the sample size calculation or rationale (risk of material misstatement, expected error rate, confidence level) and show awareness of practical constraints for a junior role.
- Outline steps you would perform on each selected item (send confirmations, review subsequent cash receipts, inspect contracts, check aging and impairment calculations).
- Discuss how you would document results, extrapolate errors to the population, assess the need for additional procedures, and communicate findings to the senior auditor.
What not to say
- Choosing a sample arbitrarily without linking size/method to assessed risk or materiality.
- Focusing only on mechanical steps (e.g., 'send confirmations') without explaining why each procedure is needed.
- Ignoring local factors such as common payment terms in Italy or language/documentation issues with SME clients.
- Claiming that sampling removes all risk of error or that small samples are always sufficient.
Sample answer
“First I'd confirm the audit objective: to test existence and valuation of accounts receivable. Based on the client risk profile and preliminary materiality (set per firm policy—for example, 2% of profit before tax), I'd set a tolerable misstatement for receivables. Given an SME with moderate risk, I would choose a statistical sample to provide quantifiable confidence, calculating sample size from the population value, expected error rate (low-medium), and desired confidence level. For each selected account I'd send external confirmations in Italian where necessary, review cash receipts after year-end, inspect sales invoices and delivery notes, and check the aging schedule and impairment policy against Italian GAAP. If errors are found, I'd extrapolate to the population and discuss with the senior auditor whether to expand sampling or propose adjustments. All steps and rationales would be documented in the working papers.”
