Transactional Data Reporting: What to Know, and What to do Next
If you’ve been following the General Services Administration’s (GSA) Multiple Award Schedule (MAS) Solicitation refreshes, you’re likely aware that there have been changes and updates to the Transactional Data Reporting (TDR) pilot. With Refresh 27, GSA has concluded the TDR pilot, and has begun to make TDR mandatory for specific Special Item Numbers (SINs). GSA has advised that all SINs will eventually come under the mandatory TDR umbrella. Because this change will impact all GSA MAS Contractors, we’re providing a brief explanation of TDR and the changes to come.
Introduction to TDR
Transactional Data Reporting (TDR) is a “prices paid” data collection initiative led by the General Services Administration (GSA) under the Multiple Award Schedule (MAS) program. Launched as a pilot in 2016, TDR was introduced to increase pricing transparency, enhance government buying intelligence, and streamline the burden of compliance on contractors.
Under TDR, contractors submit detailed sales data on a monthly basis, by invoice line item, rather than by contract total, via the FAS Sales Reporting Portal (SRP). This data includes key elements such as product/service descriptions, quantities sold, transaction prices, and customer types. In exchange, contractors are exempt from the Price Reduction Clause (PRC), eliminating the requirement to track and disclose their commercial pricing practices to the government.
Initially limited to a small group of Special Item Numbers (SINs), TDR has now evolved beyond its pilot phase. As of MAS Solicitation Refresh 27, GSA is signaling a clear move toward a fully data-driven acquisition model, making TDR mandatory for a rapidly expanding set of contractors.
Refresh 27 Changes to TDR
Refresh 27, released in June 2025, formally concludes the TDR pilot and expands mandatory participation. The most notable development is the addition of 62 new product and cloud services SINs to the list of TDR-eligible items, bringing the total number of covered SINs to 181. Click here for a list of the 181 SINs.
This expansion affects a wide array of categories, including:
– Facilities (e.g., prefabricated structures and hardware)
– Furniture & Furnishings (e.g., packaged and modular furniture, healthcare furnishings)
– Industrial Products & Services
– Information Technology (including Cloud SIN 518210C)
– Security and Protection
– Transportation & Logistics Services
Contractors with any of the 181 eligible SINs must submit a “Participate in TDR” modification via eMod. Once approved, the contract is transitioned entirely into TDR. This means that all SINs under that contract become subject to TDR reporting requirements, even if only one SIN is eligible.
Importantly, PRC obligations will end on the first day of the sales quarter following execution of the TDR modification (e.g., October 1, January 1, April 1, or July 1), aligning with GSA’s effort to simplify administration and reduce compliance risks.
The Future of TDR
GSA’s long-term vision is unequivocal: TDR will become mandatory for all MAS contractors in 2026. This means that regardless of the product or service being offered, every SIN will fall under TDR’s reporting umbrella during Fiscal Year (FY) 2026.
This change underscores GSA’s commitment to data-driven procurement strategies. By capturing transactional data across the full spectrum of offerings, GSA aims to provide government buyers with more accurate and timely price comparisons, reduce reliance on manual price negotiations, eliminate redundant reporting mechanisms, and improve overall acquisition efficiency.
As part of this transition, contractors can expect updates to the data elements required for submission. Currently, there are 12 mandatory and 4 optional fields in the reporting template. GSA may expand these fields in future refinements to better accommodate complex offerings, including configurable products and services.
Additionally, GSA has indicated plans to eventually feed TDR data into tools like GSA CALC, further enhancing transparency and competition in federal procurement. GSA already shares TDR data publicly on the Vendor Support Center (VSC) in the form of demand data. New demand data files are posted every other month and display top-selling products across GSA’s General Supplies and Services and Information Technology Category business lines.
Next Steps for Contractors
If your contract includes any of the now mandatory TDR SINs, here’s what you need to do:
1. Submit a TDR Modification in eMod by September 30, 2025
GSA requires all contractors with impacted SINs to submit a Terms and Conditions Modification via eMod labeled “Participate in TDR” no later than September 30, 2025.
2. Prepare for Reporting Requirements
TDR reporting begins on the first day of the next applicable sales quarter following the modification’s approval. Contractors must be ready to:
– Collect and submit transactional data for each MAS contract sale
– Use the FAS Sales Reporting Portal (SRP) for monthly submissions
– Ensure accuracy across all required fields, particularly for products and services with custom configurations
3. Train Internal Teams and Update Systems
Transitioning to TDR may require updates to sales tracking systems and employee workflows. Ensure that finance, sales, and compliance personnel understand the new obligations and timelines.
