How to bid on the NIST transition to IPP for invoice processing

What NIST is buying and why it matters to you

The National Institute of Standards and Technology (NIST) is updating its financial and acquisition systems. This means a change in how contractors submit invoices. Starting around October 21, 2026, all invoices must be submitted through the Invoice Processing Platform (IPP).

This is important for all current and future NIST contractors because it directly affects how you will get paid. Understanding and preparing for this transition will help ensure your payments are processed without delay.

Key dates and what happens at the deadline

The last day to submit invoices to [email protected] for FY26 payment consideration is September 11, 2026. After September 12, 2026, NIST will no longer accept invoices via email.

There will be a financial system migration period from October 1, 2026, to October 21, 2026. The Invoice Processing Platform (IPP) is estimated to be available for invoice submission around October 21, 2026. Contractors must hold invoices during the migration blackout period until IPP is available.

Who this opportunity suits

This notice is relevant for all businesses that currently have contracts with NIST or plan to bid on future NIST opportunities. It is crucial for firms involved in any category of work for NIST, as it impacts the administrative process of payment for services or goods rendered.

Your primary action is to prepare for the transition to IPP.

Ensure your SAM.gov registration is active and current to avoid payment delays.

Practical tips for preparing a competitive response

Submit any outstanding invoices for completed work and accepted deliverables as early as possible, well before the September 11, 2026, deadline for email submissions. This will help ensure timely processing before the system migration.

Familiarize yourself with the Invoice Processing Platform (IPP) if you are not already using it. Review any available IPP resources to understand its functionality and requirements for invoice submission. Maintaining an active and current SAM.gov registration is also essential for all federal contractors, as it directly impacts your ability to receive payments.
