A three-way match compares the purchase order (what was ordered), the receiving report (what was received), and the vendor invoice (what is being billed). It's crucial because it ensures the company only pays for goods/services that were ordered and actually received.
10. How do you prevent fraud in accounts payable?
Why you might get asked this:
This assesses your awareness of financial controls and ethical responsibilities in accounts payable.
How to answer:
Discuss implementing and adhering to internal controls like segregation of duties, proper authorization, vendor verification, and using system features for detection.

Describe receiving expense reports with receipts, verifying against policy, obtaining approval, and processing payment, often separately from vendor invoices.
Example answer:
For expense reimbursements, employees submit reports with supporting receipts. Accounts payable verifies expenses against company policy, obtains manager approval, and then processes the reimbursement payment, often through payroll or direct deposit.
18. How do you handle duplicate payments?
Why you might get asked this:
Preventing and resolving duplicate payments is a key efficiency and control task in accounts payable.
How to answer:
Describe using system controls (software flags), careful manual review, and if a duplicate occurs, contacting the vendor for a refund or credit memo and implementing measures to prevent recurrence.
Example answer:
I use AP software features designed to flag potential duplicates during entry. If one slips through, which can happen, I immediately contact the vendor, provide evidence of the duplicate payment, and work with them to get a refund or apply a credit memo.
19. Can you describe the month-end closing process related to accounts payable?
Why you might get asked this:
This assesses your understanding of AP's role in financial reporting and period closing.
How to answer:
Explain tasks like ensuring all received invoices are recorded before the cutoff, reconciling vendor statements, accruing for goods/services received but not yet invoiced, and preparing reports.
Example answer:
The accounts payable month-end close involves ensuring all invoices received up to the cutoff date are entered and processed, reconciling key vendor statements, calculating and recording accruals for services or goods received but not yet invoiced, and preparing aged payables reports.
20. What measures do you take to maintain data accuracy in accounts payable?
Why you might get asked this:
Accuracy is critical in AP to avoid errors, overpayments, and incorrect financial statements.
How to answer:
Mention techniques like careful data entry, using automation features, performing regular reconciliations (vendor statements, GL), and implementing review processes.
Example answer:
To maintain data accuracy in accounts payable, I double-check data entry against source documents, utilize system validations, perform regular reconciliations of vendor statements and the AP aging report to the general ledger, and request second reviews for complex items.
21. How do you deal with vendors who send incorrect invoices?
Why you might get asked this:
This tests your ability to handle vendor communication and problem-solve invoice issues in accounts payable.
How to answer:
Describe contacting the vendor promptly, clearly explaining the error found, providing necessary documentation, and requesting a corrected invoice or clarification before processing the payment.
Example answer:
When a vendor sends an incorrect invoice, I contact them directly to point out the error, referencing the relevant PO or receiving report. I explain exactly what needs correction and request a revised invoice or clarification before processing any payment.
22. Explain the importance of segregation of duties in accounts payable.
Why you might get asked this:
This is a core concept in internal controls. Understanding it shows your awareness of fraud prevention.
How to answer:
Define segregation of duties and explain how dividing tasks (initiation, approval, processing, recording) among different people prevents a single person from committing and concealing fraud.
Example answer:
Segregation of duties is vital in accounts payable as it prevents fraud and errors. By separating responsibilities like ordering goods, receiving them, approving invoices, and processing payments among different individuals, no single person has control over an entire transaction lifecycle, which reduces risk.
23. What experience do you have with accounts payable audits?
Why you might get asked this:
Audits are standard. Interviewers want to know if you can support auditors and understand the process.
How to answer:

24. How do you handle early payment discounts?
Why you might get asked this:
This shows you understand how AP can contribute to cost savings and cash flow optimization.
How to answer:
Explain that you prioritize invoices with early payment discounts when cash flow allows, ensure they are processed within the discount window, and track the savings achieved.
Example answer:
I identify invoices offering early payment discounts during processing. If the company's cash flow permits, I prioritize these payments to take advantage of the savings, ensuring they are processed within the specified discount period (e.g., 10 days for 2/10 net 30).
25. What is an accrued liability in accounts payable?
Why you might get asked this:
This tests your knowledge of accrual accounting principles relevant to accounts payable.
How to answer:
Define an accrued liability as an expense incurred but not yet billed or paid. Explain why it's recorded (matching principle) and its relevance to accurate period reporting.
Example answer:
An accrued liability in accounts payable is an expense a company has incurred during an accounting period but hasn't yet received an invoice for or paid. It's recorded at month-end to match expenses to the period they occurred, ensuring accurate financial statements, such as accruing for utility usage before the bill arrives.
26. How do you stay organized when processing a large volume of invoices?
Why you might get asked this:
AP roles often involve high volume. This assesses your efficiency and system skills.
How to answer:
Discuss using workflow tools or software, batch processing, maintaining a clear filing/tracking system, prioritizing tasks, and avoiding backlog through consistent daily processing.
Example answer:
Handling a large volume of invoices requires a systematic approach. I use AP software with workflow features, sort invoices by type or due date, maintain a clear digital or physical filing system, process invoices in batches, and commit to processing daily to prevent backlogs and stay organized.
27. What key metrics do you use to measure the effectiveness of the accounts payable process?
Why you might get asked this:
This shows you understand how to evaluate performance and identify areas for improvement in accounts payable.
How to answer:
Mention metrics like Days Payable Outstanding (DPO), average invoice processing time, error rate, early payment discount capture rate, and cost per invoice.

This tests your ability to act quickly under pressure and communicate effectively regarding accounts payable emergencies.
How to answer:
Describe verifying the urgency/reason for overdue status, confirming funds, obtaining immediate approval, communicating with the vendor and relevant internal parties, and expediting the payment through appropriate channels.
Example answer:
For urgent or overdue payments, I first confirm the reason for the urgency and verify that all documentation and approvals are in order. I communicate immediately with management and the vendor, prioritize processing the payment, and use the fastest available method, like a wire transfer, if necessary, while ensuring proper audit trails.
29. Can you explain electronic payment methods and their benefits?
Why you might get asked this:
This assesses your familiarity with modern payment methods used in accounts payable.
How to answer:
List methods like ACH, wire transfers, or virtual cards. Explain benefits such as speed, reduced costs, improved security, better tracking, and reduced paper usage compared to checks.
Example answer:
Electronic payment methods in accounts payable include ACH transfers, wire transfers, and virtual credit cards. Their benefits are numerous: they are faster and more cost-effective than checks, offer enhanced security, provide clearer audit trails, and reduce the environmental impact of paper processing.
