The Late Payment Invoice is a critical document in Pakistani business operations, used when a payment becomes overdue according to previously agreed terms. This document is typically issued after the payment deadline has passed and initial reminder notices have been unsuccessful. It includes the original invoice details, calculates additional charges as permitted under Pakistani commercial law, and serves as a formal demand for payment. The document must comply with various Pakistani regulations, including the Contract Act 1872 and relevant taxation laws, while clearly stating the original amount, late payment charges, and total sum now due. It forms an important part of the audit trail and can be used as evidence in legal proceedings if the debt recovery process needs to be escalated to courts.
