Chapter 6 Discounts

6.1 Discount Requirements

6.1.1 NASA should take economically justified discounts offered by vendors, whether stipulated in the contract or offered on an invoice, but only after acceptance has occurred.

6.1.2 Calculating the Discount. The Treasury BFS Web site offers a discount calculator that NASA should use to determine whether or not to accept the discount.

6.1.2.1 If NASA takes a discount after the deadline, the Agency will pay an interest penalty on any amount remaining unpaid as prescribed in 5 CFR § 1315.10(a)(6).

6.2 Payment Date

6.2.1 Payment date. When a discount is taken, payment will be made as close as possible to, but no later than, the discount date.

6.2.2 Start date. The period for taking the discount is calculated from the date placed on the proper invoice by the vendor. If there is no invoice date on the invoice by the vendor, the discount period will begin on the date a proper invoice is actually received and date stamped or otherwise annotated by the designated Agency office.
