(a) The detailed process for invoicing and payment of the service fee will be determined on a project by project basis. Typically, service fee payments will be made either monthly or quarterly.
(b) If government disputes the private party's claim for payment, it may notify the private party of the amount that government considers it should pay and why it differs from the private party's claim. Government will pay any undisputed part of the payment on the date that payment is due.
(c) If, after government has paid the private party's claim, it disputes the private party's entitlement to the amount of the claim (or part thereof), and to the extent it is determined (by independent expert or otherwise) that an overpayment was made, government will deduct the overpayment from any amounts due in the following payment period.
(d) Payment of moneys by government to the private party will not, of itself, be evidence that any works or Contracted Services have been carried out in accordance with the project agreement.
(e) Any late payment of amounts that are properly due and payable (including a previously disputed amount where the dispute is resolved in favour of the private party), will incur interest at a pre-agreed default rate.
(f) All payments by government will be made in arrears.
