What is the Contractor's obligation regarding invoice submission?

The correct answer highlights that the Contractor must submit invoices on a monthly basis unless there are specific instructions outlined in Appendix E. This approach is beneficial for maintaining a consistent cash flow and ensures that the contractor is regularly compensated for ongoing work. Monthly invoicing allows for timely review and processing of payments, making it easier for both the contractor and the client to manage their financial obligations and track project progress effectively.

The reference to Appendix E signifies that there can be exceptions or adjustments to this standard practice, accommodating unique project requirements or agreements made prior to the work commencing. This flexibility is crucial in construction and service contracts, as projects can vary significantly in scale and complexity.

Understanding this invoicing schedule is essential for contractors to ensure compliance with contract terms and maintain good financial management while preventing potential disputes regarding payments.
