GSA Reporting Requirements Explained

When it comes to managing a GSA Schedule Contract, there are two key reporting frameworks to understand: Commercial Sales Practices (CSP) and Transactional Data Reporting (TDR). Each system comes with its own set of rules, deadlines, and compliance requirements that directly affect your standing as a contractor. This overview lays the groundwork for the reporting deadlines and submission processes detailed in the next sections.

CSP and TDR Overview

The Commercial Sales Practices (CSP) framework has been the traditional method for GSA reporting. With CSP, contractors must disclose their commercial discounting practices to establish their Most Favored Customer (MFC) and Basis of Award (BOA). These disclosures are tied to the Price Reduction Clause (PRC), which ensures the government gets pricing equivalent to that offered to your BOA customer.

CSP contractors are required to submit a CSP-1 form when making their GSA MAS offer. Throughout the contract, they must maintain the pricing relationship between the MFC/BOA and the government. Reporting under CSP involves submitting quarterly aggregate sales data for each Special Item Number (SIN) via the FAS Sales Reporting Portal.

On the other hand, Transactional Data Reporting (TDR) takes a more detailed, data-centric approach. TDR requires contractors to report transaction-level information for every purchase made through the MAS Program. This includes data such as the actual price paid by the government, contract numbers, delivery orders, manufacturer details, quantities, and shipping information. Unlike CSP, TDR eliminates the need for CSP disclosures and PRC monitoring.

The primary difference between the two systems is in the level of detail and frequency of reporting. CSP requires quarterly aggregate sales reporting, while TDR mandates monthly submissions with 16 specific data points. Here’s a quick comparison:

GSA estimates that adopting TDR saves contractors around 22 labor hours and over $3,000 in reporting costs per contract annually. However, implementing TDR also requires robust data systems capable of managing detailed transaction records.

The shift toward TDR is gaining momentum. GSA is expanding TDR requirements across more SINs, with plans to make it mandatory for all products and cloud SINs. Contractors impacted by these changes must opt into TDR by September 30, 2025, and accept modifications within 90 days of issuance.

Key Compliance Goals

Both CSP and TDR are designed to ensure transparency and compliance, but they take different approaches to achieve these goals.

• CSP focuses on maintaining pricing relationships between your government contracts and commercial customers. If your BOA customer receives better pricing, the government must also benefit through the Price Reduction Clause.
• TDR emphasizes transaction-level visibility into what federal agencies actually pay for goods and services. This data-driven approach helps GSA monitor pricing trends and gain insights into the federal marketplace.

As Jacqueline K. Unger, Partner at PilieroMazza, explains:

"This move marks a major expansion of GSA’s data-driven procurement approach and will require contractors to adapt quickly. If you hold an MAS contract and have not yet opted into TDR, now is the time to prepare for new compliance obligations and evaluate how TDR will affect your reporting, pricing, and business strategy."

For CSP contractors, compliance involves monitoring price reduction violations and maintaining complex pricing relationships. TDR contractors, on the other hand, must focus on accurate transaction details and timely monthly reporting.

Regardless of which framework applies to your contract, the stakes are high. GSA is increasing its enforcement efforts to improve MAS program efficiency. Contractors who fail to meet minimum sales thresholds, submit accurate reports, or remit Industrial Funding Fee (IFF) payments on time are being closely scrutinized.

In the next section, we’ll dive into the specific reporting deadlines and schedules that contractors need to follow to stay compliant.

GSA Reporting Deadlines and Schedules

Keeping track of GSA reporting deadlines is essential for staying compliant. The requirements vary depending on whether you’re under the CSP or TDR framework, and missing these deadlines could have serious repercussions for your federal contracting business. Below, we’ve outlined the key deadlines, upcoming changes, and a comparison of reporting schedules to help you manage the process smoothly.

Monthly and Quarterly Reporting Deadlines

If you’re a TDR contractor, you’ll need to follow a monthly reporting schedule. This means submitting transactional data within 30 days after the end of each month. Each report must include all 16 required transactional data elements for every transaction under your GSA Schedule Contract.

For CSP contractors, reporting is done on a quarterly basis, with reports due 30 days after the end of each quarter. Since the federal fiscal year runs from October 1 to September 30, here’s a breakdown of the quarterly deadlines:

• Q1 (Oct-Dec): Reports due by January 30
• Q2 (Jan-Mar): Reports due by April 30
• Q3 (Apr-Jun): Reports due by July 30
• Q4 (Jul-Sep): Reports due by October 30

Additionally, IFF payments are required 30 days after the end of each quarter for both TDR and CSP contractors.

If you’re transitioning to TDR, the obligation to start capturing data begins with the next sales reporting quarter after signing the TDR modification. For example, if you sign the modification in February, data capture starts on April 1.

Upcoming Changes to Reporting Requirements

Changes to reporting schedules are on the horizon, with new mandates that could affect your deadlines. MAS Solicitation 47QSMD20R0001 Refresh 27 expands TDR eligibility to include 62 more SINs, bringing the total number of TDR-eligible SINs to 177. This update makes TDR mandatory for all Product SINs and the Cloud SIN (518210C). Contractors impacted by these changes must accept the mass modifications within 90 days of issuance.

These updates highlight the importance of proactively preparing your data systems and reporting workflows to ensure you’re ready for the transition.

Reporting Schedule Comparison

Here’s a side-by-side look at the differences between TDR and CSP reporting frameworks:

The monthly TDR schedule requires more frequent submissions and detailed tracking of individual transactions. This means you’ll need robust systems to handle the level of granularity involved. On the other hand, the quarterly CSP schedule allows more time for preparation but requires careful monitoring of aggregate sales, Most Favored Customer relationships, and compliance with the Price Reduction Clause.

Both frameworks rely on the FAS Sales Reporting Portal for submissions, but the type of data you’ll need to prepare differs significantly. With TDR becoming mandatory for Product and Cloud SINs, many contractors will need to shift from quarterly to monthly reporting. This change will likely impact your internal processes, from data management to staff training and compliance efforts. Proper preparation is key to navigating these transitions effectively.

How to Prepare and Submit GSA Reports

Preparing and submitting GSA reports involves understanding the specific data requirements, navigating the submission portal, and ensuring data accuracy through quality controls. Whether you’re managing CSP or TDR reporting, having the right tools and procedures in place is key to meeting deadlines and staying compliant.

Data Requirements for CSP and TDR

The type of data you need to collect and report depends on whether you’re working under the CSP or TDR framework. Each has distinct requirements, so it’s essential to tailor your tracking systems accordingly.

For CSP (Commercial Sales Practices), contractors focus on quarterly reporting of aggregate sales data. This includes:

• Total sales per Special Item Number (SIN)
• Discount and pricing information
• Monitoring Most Favored Customer (MFC) relationships

Additionally, contractors must comply with the Price Reductions Clause, documenting any commercial price reductions that could trigger adjustments to GSA pricing.

In contrast, TDR (Transactional Data Reporting) requires detailed, transaction-level reporting. For each transaction, contractors must provide 12 core data elements, including:

• Contract or BPA Number
• Delivery/Task Order Number/PIID
• Non-Federal Entity
• Description of Deliverable
• Manufacturer Name and Part Number
• Unit Measure (e.g., each, hour, case)
• Quantity Sold
• Universal Product Code
• Price Paid Per Unit
• Total Price
• Special Item Number (SIN)

TDR also includes four optional data fields, such as Order Date and Ship Date, which may become mandatory as compliance evolves.

One significant difference is that TDR eliminates the need to track Commercial Sales Practices disclosures, MFC relationships, and compliance with the Price Reductions Clause. This offers more flexibility in pricing since contractors no longer need to align commercial and GSA pricing.

Using the FAS Sales Reporting Portal

Once your data is ready, submissions are made through the FAS Sales Reporting Portal (SRP). This platform is used for both CSP and TDR reporting. GSA has implemented stricter field controls and compliance checks within the portal to improve data accuracy. For TDR reporting, it’s critical to ensure your systems can capture the required line-item data. Additionally, your reporting team must have valid GSA credentials to access and use the portal.

Steps for Accurate Submissions

To ensure your reports are accurate and compliant, follow these steps:

• Automate Data Collection: Automating the process minimizes errors, especially for TDR’s monthly reporting requirements.
• Audit Your Data: Double-check that all required fields are complete, SIN numbers align with your contract, and pricing matches GSA terms. Common mistakes include mismatched PIIDs, incorrect unit measures, or missing manufacturer details.
• Keep Detailed Records: Save copies of each submission, including confirmation messages or feedback from the portal. These records are invaluable for resolving audit requests or discrepancies.
• Stay Updated: Regularly review GSA updates about the SRP, as field controls and validation rules are refined periodically. Staying informed ensures your systems remain compliant.

GSA estimates that adopting TDR can save contractors over $3,000 annually and reduce reporting time by 22 labor hours per contract. However, TDR reporting can be more demanding than CSP due to its frequency and level of detail. With TDR now mandatory for many SIN holders, investing in reliable data systems and processes is essential for a smooth transition and continued compliance.

Best Practices for GSA Reporting Compliance

Staying compliant with GSA reporting requirements demands careful planning, accuracy, and a well-organized approach. The transition to monthly Transactional Data Reporting (TDR) and the frequent updates through mass modifications mean contractors need efficient systems to avoid errors that could jeopardize their contract status or catalog visibility.

Common Reporting Errors to Avoid

Some errors crop up more often than others in GSA reporting, and they can cause significant delays or compliance issues. Here are the most common ones to watch out for:

• Incorrect SIN selection: Always double-check that your Special Item Number (SIN) aligns with your offerings. Use the GSA eLibrary as a reference and consult with GSA representatives or experts when unsure.
• Poor financial documentation: Ensure your financial records are complete, up-to-date, and compliant with GAAP standards. Having them reviewed by a qualified accountant before submission can save you headaches down the line.
• Administrative oversights: Use an internal checklist to confirm all required documents are accurate and complete before submission.
• Inadequate pricing support: Provide thorough documentation of prior sales and market research to back up your pricing.

By addressing these common pitfalls, you’ll be in a better position to meet deadlines and maintain compliance.

How to Stay on Top of Deadlines

Missing deadlines for the Multiple Award Schedule (MAS) program can lead to serious consequences, like losing contract status or catalog visibility. Starting in June 2025, TDR SIN holders will need to submit monthly sales data. Here are some tips to help you stay ahead of your deadlines:

• Subscribe to GSA Interact and the Vendor Support Center for updates on policies, refresh notices, and announcements.
• Create internal compliance calendars that include key milestones, such as mass modification acknowledgments (which must be completed within 90 days) and monthly TDR and quarterly reporting deadlines.
• Update templates and pricing documents as soon as new versions are released to avoid using outdated materials.
• Stay in close communication with your Contracting Officer to understand how schedule changes or refreshes may impact your contract or catalog.
• Clearly define reporting responsibilities for all team members to avoid confusion.
• Use tools like automated reminders to track deadlines and monitor notifications from the Vendor Support Center and eMod.

Staying organized and informed is key to meeting deadlines and avoiding disruptions.

Preparing for Regulatory Changes

As part of its modernization efforts, GSA is rolling out initiatives like the OneGov Strategy to streamline federal procurement processes and prepare contractors for new requirements.

"The OneGov Strategy is a bold step forward for President Trump’s GSA and our mission to be responsible stewards of taxpayer dollars. It’s about acting as one – aligning to our scale, standards, and security to meet the needs of today’s government while preparing for the future." – Stephen Ehikian, GSA Acting Administrator

The expansion of TDR is one of the most immediate changes on the horizon. Currently required for all product SINs and cloud SIN 518210C, TDR will soon apply across all SINs in the MAS program. To get ready for these changes:

• Audit your data and adjust your processes to comply with evolving TDR requirements.
• Address any inconsistencies or errors in your reported data to prepare for increased oversight.
• Conduct regular reviews of pricing, commercial sales practices, and disclosures to ensure accuracy during contract renewals.

Conclusion

Meeting GSA reporting deadlines isn’t just about staying compliant – it’s about securing your place in the federal marketplace and setting your business up for growth. With the introduction of Transactional Data Reporting (TDR) and shifting compliance requirements, small businesses need to stay agile to keep up.

Key Deadlines and Tips

The 15th of each month is the most important date for TDR submissions via the FAS Sales Reporting Portal. Staying on top of this monthly task requires consistent data management. Additionally, don’t forget to update your SAM.gov profile annually to maintain your active registration.

TDR simplifies compliance by removing complex pricing relationships and easing audit requirements. That said, it comes with its own challenges – more frequent reporting and detailed data submissions, including specific transaction-level details.

To avoid errors, automate your processes. Standardizing data formats, conducting pre-submission audits, and routinely checking the Sales Reporting Portal can help you stay on track. Keep in mind that opting into TDR is irreversible, so ensure your data management systems are ready before committing. These practices not only help you meet deadlines but also prepare your business for the next steps in GSA compliance.

Next Steps for Small Businesses

After securing your MAS contract, register it in the Vendor Support Center, complete the mandatory "Pathways to Success" training, and confirm your TDR status. To do this, register for a FAS ID and access the Sales Reporting Portal at least 15 days before your first reporting period ends.

Track all sales by Special Item Number (SIN) and ensure industrial funding fees are paid within 30 days of each reporting period. Regular audits, timely contract renewals, and catalog updates are also critical for maintaining your GSA Schedule contract.

If managing these tasks feels overwhelming, consider seeking expert help. GSA compliance is demanding, and having the right support can make a significant difference. Evaluate whether your internal team has the capacity to handle the growing requirements, especially since TDR eligibility hinges on the SINs tied to your contract.

When you prioritize compliance, you’re doing more than meeting obligations – you’re securing your business’s future in the federal marketplace. Your GSA contract opens the door to one of the largest procurement systems in the world. By investing in strong compliance practices, you ensure your business remains competitive while streamlining operations to support long-term growth.

FAQs

What’s the difference between CSP and TDR reporting, and how does it affect contractor compliance?

The main distinction between CSP (Commercial Sales Practices) and TDR (Transactional Data Reporting) is in the frequency and depth of data contractors are required to report. With CSP, contractors provide a quarterly summary of their sales data. In contrast, TDR calls for monthly submissions that include detailed, transaction-level information.

This difference has a noticeable effect on compliance efforts. Contractors working under TDR may encounter greater administrative demands because of the need for more frequent and granular reporting. On the flip side, TDR allows the GSA to access more current sales data, which can simplify certain processes for contractors over time.

What steps should contractors take to prepare for the mandatory TDR requirements by September 30, 2025?

To meet the Transactional Data Reporting (TDR) requirements by the September 30, 2025 deadline, contractors need to act now to ensure they’re prepared. The first step is submitting a TDR modification through eMod. Taking care of this early can help avoid last-minute complications.

Beyond that, contractors should focus on the following:

• Educating internal teams: Make sure your team understands the expanded reporting rules and how they affect day-to-day operations.
• Upgrading reporting systems: Adjust your systems to accurately capture and manage the data required under the new guidelines.
• Reviewing the updated scope: The reporting now applies to all product and cloud service SINs, so ensure nothing is overlooked.

By addressing these areas, contractors can stay on top of the changes and simplify their compliance process.

What are the most common mistakes businesses make in GSA reporting, and how can they ensure compliance?

Mistakes in GSA reporting often stem from submitting incomplete or incorrect data, missing deadlines, or failing to stay updated on changes to GSA regulations. These missteps can result in compliance problems and even penalties.

To steer clear of these issues, businesses should focus on setting up thorough internal review procedures, keeping up with regulatory updates, and double-checking the accuracy of all submitted data. Regular training for staff and collaborating with seasoned GSA consultants can make the process smoother and help ensure compliance.
