Payment Extension

Pronunciation: PAY-munt ihk-STEHN-shun

Definition

A payment extension adds time to a payment due date, invoice expiry, checkout window, quote, authorization, or other payment deadline. The extension should define which terms remain valid and whether amount, rate, fees, or access changes. Payment Extension requires named ownership and auditable controls for payment authorization, execution, fulfillment, and financial posting. Material operational risks include unclear payer intent, invalid obligations, thresholds that block legitimate users, misleading fees, duplicate collection, premature service delivery, expired terms, milestone disputes, and inconsistent refund treatment.
