New HHSAR IPP Clause
All existing awards will be modified to include a new Health and Human Services Acquisition Regulation (HHSAR) clause HHSAR 352.232-71 Electronic Submission of Payment Requests (February 2, 2022) along with your company/organization’s transition date to IPP. All existing NIH Vendors should use the OFM Electronic Invoice Submission instructions until your company/organization has been notified of its transition to IPP. All new awards to new Vendors will contain HHSAR clause 352.232-71 and use IPP upon award.
