Following the mandatory TDR rollout under Refresh #31, every MAS Schedule contractor now faces a fundamentally different reporting reality. Monthly submissions, expanded data fields, tighter validation checks, and a hard compliance deadline of January 1, 2027 – the stakes have never been higher. Yet many contractors are still treating TDR as an afterthought. The Grace Period ending December 31, 2026 isn’t just a transition window – it’s your last chance to build the systems, processes, and internal discipline needed to withstand full enforcement. In this live session, our GSA experts will walk you through exactly what TDR requires, how to submit accurately through the Sales Reporting Portal (SRP), and the specific mistakes that trip up most contractors – plus a step-by-step SRP walkthrough you can apply to your very next submission.

What TDR is, why GSA implemented it, and confirmation that it now
applies to every MAS contract holder.

How reporting requirements differ across products, services, and
cloud offerings, plus the specific data fields for each.

The Trial Period phasing in expanded data requirements – Ship Date, Order Date, ZIP Code, UCID, Cloud Service Type – and how to prepare your systems now.

How long to retain TDR documentation, what GSA auditors look for, and the internal record keeping habits that keep you protected long after submission.

MAS sales vs. commercial, open market, and non-Schedule sales – the simple test that keeps your reports clean.

What “no penalties through December 2026” actually means, why A909 acceptance is non-negotiable, and how to use the Grace Period strategically.

Frequently Asked Questions

Yes. As of Refresh 31, released on April 2, 2026, TDR is mandatory for all MAS SINs. There are no opt-outs remaining, every active MAS contractor is now subject to TDR reporting requirements.

Mass Mod A909 is issued to contractors whose contracts were previously operating under non-TDR requirements. After accepting A909, contractors must then accept the “Participate in TDR” modification. Accepting both is non-negotiable for maintaining contract compliance.

Contractors that accept the TDR modification by the deadline will have an effective date of July 1, 2026, establishing a grace period through December 31, 2026. The grace period means no penalties during this window, but reporting obligations still apply and records must be maintained from the effective date.

You must report products or services that are directly linked to your GSA MAS contract, including BPAs. Sales from other commercial or government contracts or orders do not apply.

TDR is due within 30 calendar days after the end of the previous month, making it a monthly reporting requirement submitted through GSA’s Sales Reporting Portal (SRP).

Product contractors report 16 data points, while service contractors report 11. For 2026–2027, additional trial period fields are being phased in, including Ship Date, Order Date, ZIP Code, UCID, and Cloud Service Type.

By eliminating Commercial Sales Practices disclosures and the responsibilities associated with the Price Reductions Clause, TDR reduces the barrier of entry for all businesses, and for small businesses in particular. CSP-1 disclosures and Most Favored Customer tracking are also no longer required under TDR.

Misinterpreting transition timelines is one of the most common issues contractors face during the shift to TDR. Other frequent errors include reporting commercial sales outside of the MAS contract, using internal product codes that don’t match GSA data fields, and submitting incomplete monthly data.
