Think of Transactional Data Reporting (TDR) as GSA’s upgraded lens into your contract pricing. Blurry, black-and-white CSP disclosures no longer cut it. As of MAS Refresh 27, TDR is no longer in pilot mode—it’s now mandatory for 177+ eligible SINs, with full MAS coverage expected by FY 2026.
What This Means for You
Monthly Reporting Is Now Required
Contractors must report 16 transactional data elements—including part numbers, quantities, unit prices, customer name, order date, and ship-to ZIP code—through GSA’s Sales Reporting Portal within 30 days of each month’s close.
CSP and PRC Are Going Away
TDR eliminates the need for Commercial Sales Practices disclosures, Most Favored Customer tracking, and Price Reductions Clause monitoring. A major compliance burden lifted.
Deadline: September 30, 2025
All current Schedule holders with eligible SINs must accept the mass modification by September 30, 2025. Monthly reporting starts with the new quarter—October 1, 2025.
VA FSS Contracts Are Not Affected
TDR does not apply to VA’s Federal Supply Schedule contracts at this time.
Why GSA Is Moving Quickly
Better Procurement Decisions
TDR supports the government’s Category Management initiative by delivering monthly-level insight into purchasing trends, pricing, and vendor performance.
More Transparent Oversight
Replacing the PRC, TDR allows for cleaner, data-driven compliance reviews. However, strong internal systems are now a must.
Potential Risks to Contractors
Data Quality Challenges
A recent Inspector General report found that 73% of TDR-reported service sales data was unusable. GSA expects improvement—and will notice if you’re not delivering clean data.
Closer Scrutiny of Discounts
GSA will examine order-level pricing more closely. If your discounts seem inconsistent or excessive, you’ll need documentation to justify them—especially during contract renewals.
Your TDR Compliance Action Plan
| Step | Description |
|---|---|
| 1. Audit Your SINs | Determine whether your contract includes TDR-eligible SINs. If so, begin preparing for the mass modification. |
| 2. Clean Up Your Systems | Ensure your systems can accurately capture and report all 16 required data elements—especially for service-based sales. |
| 3. Accept the Mass Mod | Complete the mass mod no later than September 30, 2025. Monthly reporting begins October 1, 2025. |
| 4. Get Expert Support | Ensure your team is trained and your systems are aligned. This transition often requires hands-on help. |
Why Now?
TDR simplifies some compliance burdens—but raises the bar on accuracy and transparency. GSA is shifting away from vague quarterly summaries and CSP disclosures. In their place, they want monthly, line-item-level visibility. This change brings risk—but also an opportunity to demonstrate credibility, pricing discipline, and operational readiness.
