With the release of GSA’s Multiple Award Schedule (MAS) Solicitation Refresh #31 earlier this year, Transactional Data Reporting (TDR) is now mandatory for all SINs under MAS. As of July 1, 2026, all MAS contracts are subject to TDR, and all contractors are required to begin reporting sales monthly.
To help contractors prepare for this transition, we have published extensive TDR content to ensure our clients receive the most up-to-date information about TDR. This blog highlights key information about filing your first TDR sales report so you’re ready when the time comes.
Transactional Data Reporting (TDR) is used by GSA to better understand the government’s purchasing patterns. TDR was introduced as a pilot program in 2015 and became mandatory for all MAS contractors in 2026, replacing Commercial Sales Practices (CSP). It allows GSA to collect data on the prices paid for products and services sold through MAS, helping the agency analyze buying behavior more effectively.
As mentioned above, the retirement of the Price Reductions Clause (PRC)/CSP took effect on July 1, 2026, and sales reporting for new contractors is due on August 30th. GSA is now providing a grace period for new participants (contractors that opted into TDR anytime between October 1, 2025, and July 1, 2026) through December 31, 2026. New contractors will not be penalized for discrepancies in sales reporting during this period. Instead, compliance will be enforced starting in January 2027.
Similar to previous quarterly sales reporting, TDR sales reporting is done in the Sales Reporting Portal (SRP). TDR data can be submitted through either form entry or file upload. With form entry, you enter your sales data directly into SRP. With file upload, you complete the TDR sales reporting spreadsheet and upload it to the system. When reporting sales through a file upload, be sure to download a new template from SRP as GSA periodically updates the template. You can switch between reporting methods each month.
If you have zero sales for a given month, you’ll still need to submit a report. Under “form entry” in SRP, the system allows you to click “Yes” in the “Reporting Zero Sales” field on the Form Entry page. If you report zero sales, your contract risks being marked delinquent.
For every TDR report, you’ll need to report the following data:
Refresh #31 has also made four additional data elements mandatory:
In the future, GSA plans to implement the following optional data elements as mandatory for TDR reporting:
There are a couple of categories that your offerings can fall under that may impact your sales reporting. These offerings may include:
Highly configurable products, cloud services, and non-cloud configurable service offerings are required to upload a bill of materials through the sales reporting system to validate the data reported in the spreadsheet.
Since a configured product may not exactly match a product identified in your sales reporting, GSA requires additional documentation to verify that you’re reporting sales accurately. Information regarding these additional requirements is available through GSA’s reporting guidance.
If you notice a mistake in your submitted monthly sales report, you’re able to modify it using the options available under the Adjust Data menu. If you are adjusting data through a file upload, make sure to include all applicable data, as the system will override your previously submitted report with the revised file.
If you are using form entry, you can go through and revise only the lines that need correction. When you’re done with the revisions, you will also need to provide justification explaining why the changes are being made and how the issue will be prevented in future reporting.
Even though there have been some tweaks made to TDR reporting, there are currently no changes to the reporting deadlines for the Industrial Funding Fee (IFF) payment. As a reminder, IFF payments are due 30 days after the end of each quarter (January 30, April 30, July 30, October 30), but you can opt to pay them monthly. Please note that only authorized negotiators can submit sales reports, so if you need to replace your IFF POC, you can simply email your CO to make that change.
It is also important to note that CSP, Most Favored Customer (MFC), and BOA disclosures are no longer required. Additionally, contractors are no longer required to track price reduction violations.
For Firm Fixed Price contracts, reporting requirements will depend on how the Contract Line Item Numbers (CLINs) are structured. Contractors should refer to the MAS User Guide for specific reporting instructions.
For new contractors, we recommend reviewing your orders and invoices to determine whether any changes are needed to ensure your contract offerings are invoiced correctly and capture the data required for TDR reporting. For more information on TDR sales reports, check out our recent webinar.
