The Per Diem Invoice is a crucial document used in Pakistani business operations when claiming daily allowance payments for professional services. It serves as an official request for payment and a record for accounting purposes, typically used by contractors, consultants, or temporary workers who provide services on a daily rate basis. This document type must comply with Pakistani taxation requirements, including proper documentation of withholding tax and sales tax where applicable. The Per Diem Invoice includes essential details such as the service period, agreed daily rate, total days worked, tax calculations, and payment terms. It is particularly important for maintaining clear financial records and ensuring compliance with local regulatory requirements, while also serving as supporting documentation for both the service provider's income records and the client's expense claims.
