Verification Procedures 2. Coding and Invoice 3. The Serial Invoice Approval Unit approves invoices that arrive separately from the items for which we are paying. These procedures explain the route of an invoice, coding of invoices, and posting of payment on Innopac, the automated serials check-in system. It is helpful for an invoice approver to have some knowledge of the IBM Accounting System and how orders are initiated to better understand the function of invoice approval.
Purchase orders originate in the departmental libraries.
They are delivered to Acquisitions, which places the order with the appropriate serial vendor. One copy of the order form is forwarded to the Automation Unit which inputs the information into Innopac and the IBM Accounting System. A fund is a pool of money that librarians have with which to buy materials for their libraries. The fund number must appear on all orders and approved invoices. The vendor number must be noted on all approved invoices.
