What is a payment run?

‍

A payment run is the process of batching and executing payments to suppliers for approved invoices. Rather than paying each invoice individually, AP teams group approved payables together — typically on a weekly or twice-weekly cycle — and submit them as a batch to the bank for processing.

‍

The payment run is the final step in the invoice-to-pay process. By the time an invoice reaches the payment run, it has been received, validated, matched, and approved. The payment run converts approved liabilities into actual cash outflows.

What happens during a payment run

‍

The process begins with a payment proposal: the system generates a list of all invoices due within the payment window, including any where early payment discounts are available and the discount window is still open. The AP team reviews the proposal, removes any items that shouldn't be paid yet (disputes under resolution, invoices pending final approval), and submits the batch to the bank.

‍

Once submitted, payments are executed via bank transfer, NEFT, RTGS, cheque, or whichever payment method applies. Remittance advice is generated and sent to suppliers.

‍

Where it goes wrong

‍

Common payment run failures include: paying invoices that are in dispute, missing the payment window for early payment discounts, duplicate payments triggered by resubmission of invoices that were already paid, and payment runs executed with incorrect bank details due to vendor master data errors.

‍

Automated AP platforms enforce controls at the proposal stage — flagging disputes, surfacing discount opportunities, and validating bank details — before payments are executed.
