When a discount for prompt payment is taken, the designated payment office will make payment to the contractor as close as possible to, but not later than, the end of the discount period. The discount period is specified by the contractor and is calculated from the date of the contractor's proper invoice. If the contractor has not placed a date on the invoice, the due date is calculated from the date the designated billing office receives a proper invoice, provided the agency annotates such invoice with the date of receipt at the time of receipt. When the discount date falls on a Saturday, Sunday, or legal holiday when Government offices are closed, the designated payment office may make payment on the following working day and take a discount.
