Description

Dear NIST Contractors,

The National Institute of Standards and Technology (NIST) is transitioning to the Business Application Solution (BAS), which involves migrating our acquisition and financial systems, including the move to the Invoice Processing Platform (IPP). To facilitate the transfer of financial data, there will be a temporary blackout period for invoice submissions. Please review the following schedule and transition requirements to help ensure your payments are processed efficiently.

Important Dates

September 11, 2026 – Last day to submit invoices to invoice@nist.gov for FY26 payment consideration September 12, 2026 – NIST will stop accepting invoices through invoice@nist.gov September 22, 2026 – Final payment processing date for invoices submitted prior to September 11, 2026 October 1, 2026 – October 21, 2026 - Financial system migration Estimated October 21, 2026 – Invoice Processing Platform (IPP) available for invoice submission

Required Contractor Actions

Submit invoices early whenever possible. Contractors are strongly encouraged to submit all proper invoices for completed work and accepted deliverables as soon as practicable and in advance of September 11, 2026.  No invoices will be accepted at invoice@nist.gov beginning September 12, 2026. During the migration blackout period, contractors must hold invoices until the new process becomes available via IPP. Invoices submitted to invoice@nist.gov after this date will not be processed. Starting October 21, 2026 (estimated) invoices shall be submitted through IPP. Contractors must use the IPP website (www.ipp.gov) to register, access, and use IPP for submitting payment requests.  Invoices submitted to invoice@nist.gov after the migration is completed will not be processed. 

If your company is not already enrolled in IPP, the Contractor Government Business Point of Contact (as listed in SAM) will receive enrollment instructions via email.

Ensure your SAM.gov registration is active and current. Contractors are responsible for maintaining an active registration in SAM.gov to avoid payment or processing delays.

Additional instructions and implementation details will be provided as the migration progresses.

We appreciate your patience and cooperation during this transition.
