The following clause is applicable to all purchase orders, task/delivery orders and BPA Calls: Prompt Payment, as amended FAR 52.232-25. Highlights of this clause and NIH implementation requirements follow:

1. Invoice Requirements
1. An invoice is the Vendor’s bill or written request for payment under the contract for supplies delivered or services performed. A proper invoice is an “Original” which must include the items listed in bullets 1 through 11 below. If the invoice does not comply with these requirements, it can result in an invoice being considered improper and returned to the vendor.
   1. Name and Address of the Vendor
   2. Invoice date (Date Invoice Submitted)
   3. Order number and where applicable, main agreement (e.g., BPA and Contract #)
   4. Description, quantity, unit of measure, unit price, and extended price of supplies delivered or service performed
   5. Shipping and payment terms (e.g., shipment number and date of shipment, prompt payment discount terms)
   6. Name and complete mailing address where payment is to be sent per ACH information on record
   7. Name (where practicable), title, telephone number and mailing address of person to be notified in the event of a defective invoice
   8. DUNS number or DUNS+4, as registered in CCR
   9. Vendor Identification Number (VIN). NOTE: This only applies to new purchase orders, task/delivery orders and BPA Calls awarded on/after June 4, 2007. The VIN is a 7 digit number that appears after the vendor’s name on the face page of the award document in the block where the contractor’s name and address appear. Inclusion of the VIN on the invoice is not required if the invoice identifies the contractor’s DUNS or DUNS+4.
   10. Any other information or documentation required by the order (e.g., evidence of shipment)
   11. Unique Invoice Number which can only be used one time regardless of the number of contracts or orders held by an organization (or business unit identified by a separate DUNS or DUNS+4 number), regardless if the invoices are being issued out of separate locations.
2. Shipping costs will be reimbursed only if authorized by the Contract/Purchase Order. If authorized, shipping costs must be itemized. Where shipping costs exceed $100, the invoice must be supported by a bill of lading or a paid carrier’s receipt.
3. Mail the original itemized invoice to:
