Section 1-1704. REQUIREMENTS FOR PROPER INVOICES

 

1704.1In order to constitute a proper invoice for payment, an invoice shall contain the following:

 

(a)Name and remittance address of the business concern, and invoice number and date;

 

(b)Contract number or purchase order or other authorization for delivery of goods or services;

 

(c)Description, price and quantity of goods and services actually delivered or rendered;

 

(d)Shipping and payment terms;

 

(e) Vendor’s DUNS number; and

 

(f)Other substantiating documentation or information as required by contract.

 

1704.2An agency may require a business concern to provide additional information which is helpful to the designated payment officer, but which is not essential. Failure of the business concern to provide this nonessential information with the invoice shall not render the invoice defective.

 

1704.3Invoices shall be considered received by the designated payment officer on the date a proper invoice is actually received in the designated office, or the date the agency accepts the property or service, whichever is later.
