GSA Just Made TDR Mandatory Across the MAS Program

GSA Solicitation Refresh 31 expands Transactional Data Reporting to all Special Item Numbers across the Multiple Award Schedule. TDR is now mandatory program-wide. Here's what changes for contractors.

GSA released Solicitation Refresh 31 for the Multiple Award Schedule. The headline change: Transactional Data Reporting is now mandatory across every Special Item Number on the program.

That ends a decade-long pilot. TDR has been optional for most SINs since 2016. Refresh 31 closes that door.

What changes for contractors

Three things move:

  1. Pricing transparency. Every transaction under your MAS contract now reports unit-level data to GSA. Quantity, price, customer category, and SIN. No more rolling Commercial Sales Practices disclosures as your only data trail.
  2. Compliance lift. If you already had TDR turned on for some SINs, you know the operational cost. Now it applies to your full MAS portfolio. Reporting cadence is monthly.
  3. Pricing leverage shifts. GSA contracting officers will have transaction-level visibility into what you actually charge other federal customers. That changes the negotiation posture on every modification and recompete from here forward.

What to do this week

  • Audit your reporting systems. If your current TDR pipeline only covers a subset of SINs, scope what it takes to cover the rest. Most contractors are looking at 60–90 days of work.
  • Pull the refresh language. Read what Refresh 31 actually requires. Do not rely on summaries — the operational details are in the modification text.
  • Brief your contracts team. Anyone touching your MAS contract needs to know this changed. Including subcontractors who flow data up to you.
