Accounts payable clerk interview questions

Accounts payable interviews focus on accuracy, process and fraud awareness. Expect questions about how you process invoices, run payments and deal with suppliers. Some employers set a short data entry or matching test. Prepare a clear answer on bank detail changes: it's one of the most common questions now.

Process questions

1. Talk me through how you process an invoice from receipt to payment.

Why they ask: It shows you understand the whole cycle.

A strong answer covers: receipt and logging, checking against the purchase order and goods received note, coding, approval, posting, and inclusion in the payment run.

2. What is three-way matching, and why does it matter?

Why they ask: It's a key AP control.

A strong answer covers: matching the invoice, purchase order and goods received note, and how it prevents paying for things that weren't ordered or delivered.

3. How do you prepare a payment run?

Why they ask: Payment runs must be accurate and on time.

A strong answer covers: selecting approved invoices due for payment, checking for duplicates and credit notes, getting authorisation, uploading the BACS file and sending remittances.

4. How do you reconcile a supplier statement?

Why they ask: Statement reconciliations catch missing and duplicate items.

A strong answer covers: matching the statement to the ledger, identifying missing invoices, unapplied credits and payments in transit, and resolving differences with the supplier.

Controls and fraud questions

5. A supplier emails to change their bank details. What do you do?

Why they ask: Bank mandate fraud is a major risk.

A strong answer covers: never acting on the email alone, calling the supplier on a number already held (not one in the email), following the company's verification and approval process, and flagging anything suspicious.

6. How do you spot a duplicate invoice?

Why they ask: Duplicates are a common source of overpayment.

A strong answer covers: checking supplier, invoice number, amount and date, system duplicate checks, and watching for slightly altered invoice numbers.

7. What would you do if an invoice had no purchase order?

Why they ask: It tests whether you follow controls under pressure.

A strong answer covers: following the no-PO policy, contacting the budget holder for approval or a retrospective order, and not paying until it's properly approved.

People and competency questions

8. How do you handle a supplier chasing an overdue payment?

Why they ask: You'll deal with frustrated suppliers.

A strong answer covers: staying polite, finding out why it's stuck (often approval), chasing internally, giving the supplier a realistic date and following up.

9. How do you prioritise when invoices pile up before a payment run?

Why they ask: Volume peaks are common.

A strong answer covers: focusing on due dates and critical suppliers, asking for help early, and not cutting corners on checks.

10. Tell me about a mistake you caught before it became a problem.

Why they ask: Attention to detail is the core of the role.

A strong answer covers: what you noticed, how you checked it, what you did, and what would have happened otherwise.

11. Which systems have you used?

Why they ask: Systems experience reduces training time.

A strong answer covers: the accounting systems and any invoice scanning or workflow tools, and how quickly you've learned new systems before.

12. Why accounts payable?

Why they ask: They want someone who'll take pride in the role.

A strong answer covers: enjoying accuracy and process, and any plans to study AAT or progress in finance.
