When is the due date for invoice payments according to federal regulations?

The due date for invoice payments according to federal regulations is 30 days after the acceptance of supplies or services. This timeline is established to ensure that contractors receive timely payment for the goods or services they provide, recognizing the completion of their contractual obligations.

This standard aligns with the Prompt Payment Act, which emphasizes the importance of quick and efficient payment processes to maintain relationships between the government and contractors. Acceptance signifies that the government has reviewed and is satisfied with the work performed or the items delivered, marking the completion of a key step in the transaction that triggers the payment obligation.

The other options do not reflect the correct timeframe for payment processes as dictated by federal regulations. For instance, payments are not automatically tied to when a payment request is made or the submission of the contract, nor are they contingent upon the contractor's performance review, which serves a different purpose and does not dictate payment timelines.
