The Overdue Invoice document is a critical business communication tool used when payment for goods or services has not been received within the agreed-upon terms. It serves as a formal reminder and demand for payment, typically issued after the original payment deadline has passed. This document is essential in Canadian business operations, requiring compliance with federal and provincial regulations regarding debt collection, interest charges, and commercial transactions. It should be used when regular invoice payment terms have been exceeded, typically 30, 60, or 90 days past due, and before escalating to legal action. The document must include specific elements required by Canadian law, such as clear payment details, interest calculations (if applicable), and appropriate collection language while maintaining professional business standards.
