Separate the offer from the decision
Vendor payment terms may offer a discount for payment within a defined window, such as a percentage off if paid before the normal due date. The offer is a contract term. The decision to take it depends on cash position, approval authority, the accuracy of the invoice, and whether the vendor has met its obligations. Those are different questions and should have different records.
A decision log keeps the offer, the calculation, the approver, the payment date, and the outcome together. Without it, a team may capture a discount by accident, miss one because no one noticed the window, or take a discount on an invoice that later changes. The log makes the choice visible and reviewable.
Capture the terms at invoice intake
Record the discount percentage, the discount period, the net due date, and the source of the terms. The source may be a contract, a purchase order, a vendor portal, or an invoice footer. If the invoice conflicts with the contract, mark the difference and route it to the owner rather than choosing the more favorable number.
The payment calendar should show the last date to capture the discount, not only the net due date. Add the calculation basis, such as the invoice amount before or after tax, and the currency. A discount calculation that ignores a credit, a freight charge, or a tax line may produce a payment that does not match the vendor's expectation.

Prepare the decision, not just the number
For each candidate, prepare a short decision record: invoice number, vendor, amount, discount value, payment date required, available cash context, any open dispute, and the recommended action. The recommendation should state its assumptions. A payables assistant can prepare this package, but the authorized finance owner decides whether to accelerate payment.
Do not present a discount as free money. Early payment uses cash that may be needed elsewhere and may require borrowing or delaying another obligation. The decision owner should consider the organization's approved cash policy. The log should record that the tradeoff was considered, not just that a percentage looked attractive.
Record forfeitures and missed windows
Not every discount should be taken. A vendor may be in a dispute, the invoice may be inaccurate, or the approval may not arrive in time. Record the reason for forfeiture using a consistent list: cash priority, unresolved dispute, missing approval, late invoice, vendor compliance question, or terms not confirmed.
A missed window is also a process signal. If the same vendor or approval path repeatedly misses a discount, examine the intake and approval timing. Do not retroactively change the payment date or describe a late payment as a captured discount. The record should reflect what actually happened.

Review outcomes against the terms
After the payment run, compare the planned discount with the amount actually taken. Investigate differences caused by a credit, a short payment, a bank fee, or a vendor remittance mismatch. Reconcile the discount to the vendor statement or portal so the open balance is correct.
Review the log monthly for capture rate, forfeiture reasons, and repeated approval delays. These are operational measures for your own process, not industry benchmarks. Pair them with a sample review of the underlying terms and approvals so a high capture rate does not hide unauthorized acceleration.

Pilot with a small vendor group
Start with a few vendors whose terms are clear and whose invoices are stable. Define the approval threshold, the payment calendar, and the record fields. Run the process for one month and compare the decisions with the prior approach.
Expand only after the team can show that the terms were confirmed, the calculation was checked, the approval was recorded, and the payment matched the decision. The goal is not to capture every discount. It is to make each choice deliberate and explainable.
Common questions answered
Who should approve an early payment?
The organization's delegation policy should name the approver and any threshold. Payables can prepare the decision package but should not accelerate payment without the required authority.
Should tax be included in the discount calculation?
Follow the contract and the vendor's stated terms. Record the basis used so the calculation can be reviewed.
How should a discount be recorded if the invoice is later corrected?
Link the correction to the original payment and record any additional credit or short payment. Preserve the original decision and the revised outcome.
