Announcing IPP Implementation at the Library of Congress
Beginning in June 2016, the Library of Congress will be implementing the Invoice Processing Platform (IPP) to facilitate the electronic exchange of purchase orders (POs), invoices, and payment information to its suppliers of goods and services. IPP is a service provided by the US Treasury’s Bureau of the Fiscal Service designed to help your organization streamline the order-to-pay process. As a vendor to the Library, IPP is available for you to use at no cost to your company. By using IPP, vendors can receive electronic purchase orders and send electronic invoices; either through file exchange or by pulling data for invoices directly from POs. IPP provides online access to invoice status and payment information. Additional information and vendor training materials are available on-line at www.IPP.gov.
Vendors will not be able to submit invoices using IPP for contracts with Congressional Research Service (CRS), National Library Service for the Blind and Physically Handicapped (NLS), and FedLink. The Library will notify vendors as these contracts become available to invoice in IPP.
Until October 1, 2016, participation will be voluntary. In order to enroll vendors must send an email to firstname.lastname@example.org indicating their interest in participating. Please see the Registration Letter below for additional details regarding the registration process.
