Payment Runs Interview Questions & Answers

Q: What is a payment run?

A payment run (payment batch) is the scheduled process of selecting due approved invoices and paying them together, usually via bank transfer/ACH/BACS. It groups payments by due date and vendor, applies credits, generates the payment file and remittances, and posts the clearing of accounts payable in one controlled cycle.

Q: What are common payment methods used in AP?

Common methods include ACH/BACS/SEPA bank transfers (low cost, most common), wire transfers (fast, high-value, urgent), checks (declining, higher fraud risk), corporate/purchasing cards, and increasingly virtual cards. The choice balances cost, speed, security, supplier acceptance, and any rebate the buyer earns.

Q: What is a remittance advice?

A remittance advice tells the supplier which invoices a payment covers—listing invoice numbers, amounts, deductions, and credits applied. It helps the supplier's AR team apply the cash correctly and reduces unapplied-cash and reconciliation queries. It can be emailed, sent via EDI, or delivered through a portal.

Q: How are invoices selected and prioritized in a payment run?

Selection is driven by due date, approval status, payment block/hold flags, available discounts, currency, and cash availability. Approved, unblocked invoices due (or with an expiring discount) are included; disputed or held items are excluded. Treasury may cap the run to available funds, prioritizing critical suppliers and discounts.

Q: How does an early-payment discount decision get evaluated?

Compare the discount's annualized return to the company's cost of capital or short-term borrowing rate. Terms like 2/10 Net 30 give ~36% annualized (2% for paying 20 days early), usually well above financing cost, so taking it is worthwhile if cash allows. If cash is scarce and borrowing costs exceed the return, forgo it.

Q: What controls should surround a payment run to prevent errors and fraud?

Controls include segregation of duties (preparer vs approver/releaser), dual authorization of the payment file, review of a pre-run proposal/exception report, positive pay with the bank, limits and duplicate checks, secure transmission of the bank file, and reconciliation of the run total to postings. These prevent unauthorized, duplicate, or altered payments.

Q: What is a payment proposal (pre-run) and how is it reviewed?

A payment proposal is a preview of what a run will pay before execution: selected invoices, amounts, discounts, and any exceptions or blocked items. Reviewers confirm the selection is correct, discounts are captured, no duplicates or held items slip in, and the total fits available cash, then approve it for the actual run.

Q: How do payment runs support cash flow and working capital management?

By timing runs to due dates (not earlier than necessary) while capturing worthwhile discounts, AP optimizes days payable outstanding and preserves cash. Aligning runs with the cash forecast, staggering large payments, and using tools like dynamic discounting let treasury balance liquidity, financing cost, and supplier goodwill.

Q: What is positive pay and how does it prevent payment fraud?

Positive pay is a bank service where you send the bank a list of issued payments (check numbers, amounts, payees); the bank pays only items matching the list and flags exceptions for your review. Payee positive pay also verifies the payee name. It stops altered or counterfeit checks and unauthorized items from clearing.

Q: How are cross-border/foreign-currency payments handled in a payment run?

FX payments require the correct currency, an exchange rate (spot or a treasury-agreed rate), awareness of correspondent-bank fees and cut-off times, and sometimes regulatory/beneficiary information. The payable is settled at the payment-date rate, creating a realized FX gain/loss versus the invoice-date rate, which is posted on clearing.

Beginner

A payment run (payment batch) is the scheduled process of selecting due approved invoices and paying them together, usually via bank transfer/ACH/BACS. It groups payments by due date and vendor, applies credits, generates the payment file and remittances, and posts the clearing of accounts payable in one controlled cycle.

Real-world example Every Thursday AP runs a payment batch selecting all approved invoices due within the next 7 days.

Common methods include ACH/BACS/SEPA bank transfers (low cost, most common), wire transfers (fast, high-value, urgent), checks (declining, higher fraud risk), corporate/purchasing cards, and increasingly virtual cards. The choice balances cost, speed, security, supplier acceptance, and any rebate the buyer earns.

Real-world example Routine suppliers are paid by ACH, an urgent overseas payment goes by wire, and low-value tail spend uses a virtual card for rebates.

What is a remittance advice?

A remittance advice tells the supplier which invoices a payment covers—listing invoice numbers, amounts, deductions, and credits applied. It helps the supplier's AR team apply the cash correctly and reduces unapplied-cash and reconciliation queries. It can be emailed, sent via EDI, or delivered through a portal.

Real-world example A single ACH payment covering ten invoices includes a remittance so the supplier can match each invoice and clear its ledger.

Approved, unblocked invoices due (or with an expiring discount) are included; disputed or held items are excluded. Treasury may cap the run to available funds, prioritizing critical suppliers and discounts.

Real-world example A cash-constrained week's run prioritizes payroll-critical suppliers and invoices with expiring early-payment discounts.

How does an early-payment discount decision get evaluated?

Intermediate

Compare the discount's annualized return to the company's cost of capital or short-term borrowing rate. Terms like 2/10 Net 30 give ~36% annualized (2% for paying 20 days early), usually well above financing cost, so taking it is worthwhile if cash allows. If cash is scarce and borrowing costs exceed the return, forgo it.

2/10 Net 30 annualized:
  = (discount % / (100% - discount %)) x (365 / (pay period - discount period))
  = (2 / 98) x (365 / 20) ~= 37.2% annualized.

Real-world example Treasury takes 2/10 Net 30 discounts because 37% annualized far exceeds its 6% borrowing cost.

Intermediate

Controls include segregation of duties (preparer vs approver/releaser), dual authorization of the payment file, review of a pre-run proposal/exception report, positive pay with the bank, limits and duplicate checks, secure transmission of the bank file, and reconciliation of the run total to postings. These prevent unauthorized, duplicate, or altered payments.

Real-world example The payment file requires two authorizers to release, and positive pay lets the bank reject any check not on the issued list.

Common follow-ups: What is positive pay? | Why review the payment proposal before release?

DPO = (Accounts Payable / COGS) x 365.
Paying on due date rather than early raises DPO, freeing working capital.

Real-world example Shifting from paying on receipt to paying on the due date lifts DPO by 12 days and frees several million in working capital.
