INVOICES FOR PURCHASES BY SUB-PURCHASE ORDERS - 8422.103-FEB-1972
Contract numbers, where applicable, will be shown on sub-purchase order invoices. Agencies will enter the explanation "Partial delivery; Order was for (quantity)" on invoices for partial deliveries of items with unit prices governed by quantities purchased. This explanation will permit the State Controller's Office to compare the unit price claimed on the invoice with the contract price.
A detailed vendor-generated document may be used to support sub-purchase order invoices where itemization of goods purchased is not practical. Vendor-generated support documents may take the form of an invoice, cash register tape, sales slip, or ticket. The form should be customary to the vendor's business.
Sub-purchase order invoices will be completed in the usual manner except that a general description may be used in place of itemizing the purchase, e.g., groceries. The support document will be attached to the sub-purchase order invoices form and referenced in the description section. Where possible, reference will be made to a vendor-numbered document.
