Multiple Award Schedule Transactional Data Reporting Requirements
Multiple Award Schedule Transactional Data Reporting, or MAS-TDR, is a sales reporting requirement for MAS contractors to report monthly, line-item sales data through the FAS Sales Reporting Portal. MAS-TDR modernizes sales reporting for MAS contracts. It increases transparency, supports data-driven decision-making and helps create a more efficient federal marketplace.
GSA updates the MAS-TDR User Guide [PDF - 417 KB] regularly with additional reporting scenarios as the program evolves. Use this page to learn when MAS-TDR applies, what sales to report, which data fields are required, how to classify products and services, and where to get help.
MAS-TDR mandates and requirements
As of MAS Solicitation Refresh 31, released April 2, 2026, MAS-TDR, is mandatory for all MAS Special Item Numbers, or SINs.
- Contractors must accept the system-generated Refresh 31 mass modification, A909, as soon as possible and no later than 60 days after GSA issues the modification.
- After accepting Mass Mod A909, contractors must accept the “Participate in TDR” modification.
MAS-TDR reporting begins on the first day of the quarter after acceptance of the TDR modification.
Note: If your MAS-TDR effective date appears incorrect, contact your contracting officer or refer to the latest GSA guidance. Contractors who already accepted Mass Mod A909 may receive a unilateral mass modification clarifying the TDR participation effective date.
Grace period and trial period
GSA established temporary transition periods to help contractors adapt to MAS-TDR. During these periods, GSA will not take enforcement action for good-faith errors made when entering required data fields.
This temporary relief applies only to formatting and data-entry issues. It does not waive basic reporting obligations.
Grace period for new MAS-TDR contracts
The grace period applies to new contracts with a TDR effective date on or after October 1, 2025. The grace period runs from July 1, 2026, through December 31, 2026.
During the grace period, you must still:
- Report all sales each month, including zero sales.
- Complete required MAS-TDR data fields, as applicable.
- Remit the full and correct Industrial Funding Fee, or IFF, on time.
- Avoid intentional misrepresentation of sales data.
Trial period for new MAS-TDR data fields
The trial period applies to all MAS-TDR participants for newly required data fields. For the fields below, the trial period runs from July 1, 2026, through December 31, 2026.
GSA will not take formal enforcement action for good-faith errors for the following fields during the trial period:
- Ship date
- Order date
- ZIP code shipped to
- Federal customer
- Unique Catalog ID
- Cloud service type
Additional fields, including order type, worksite and order discount, are expected later. GSA plans to update the MAS-TDR User Guide when those fields are implemented. For more information, see Section 2.3.2, “Grace and Trial Period,” of the MAS-TDR User Guide.
Contract modification process and requirements
After your MAS-TDR effective date, you are no longer required to comply with certain legacy pricing disclosure and tracking requirements.
- TDR participants do not need to enter Most Favored Customer information in the FAS Catalog Platform file or Price Proposal Template.
- At offer and modification submission, supporting documentation, such as invoices, is not required unless the contracting specialist or contracting officer requests it for price analysis.
If you have issues accepting the “Participate in TDR” mass modification or the Refresh 31 mass modification, contact vsc@gsa.gov.
If your MAS-TDR effective date appears incorrect
If you have not signed Mass Mod A909, GSA will apply a correction to the pending Mass Mod A909 to ensure the effective date of MAS-TDR participation is correct.
If you already signed Mass Mod A909, GSA will issue a unilateral mass modification to clarify the TDR participation effective date as July 1, 2026.
MAS-TDR pricing impact and commercial sales practices
MAS-TDR affects certain pricing and modification requirements after your TDR modification is effective.
After your MAS-TDR effective date, MAS-TDR eliminates the requirement to:
- Provide Commercial Sales Practices, or CSP, disclosures.
- Provide Most Favored Customer, or MFC, information in the FAS Catalog Platform file or Price Proposal Template.
- Provide Basis of Award, or BOA, information.
- Maintain the BOA price discount relationship after award.
- Monitor price reduction violations under the non-TDR Price Reductions Clause.
Until the effective date of your “Participate in TDR” modification, you remain subject to the applicable non-TDR version of the Price Reductions Clause.
Price Reduction Clause
Before MAS Solicitation Refresh 31, there were TDR and non-TDR versions of the Price Reductions Clause.
As of MAS Solicitation Refresh 31, and upon the effective date of the “Participate in TDR” modification, Price Reductions Clause GSAR 552.238-81, December 2025, GSAR deviation, applies. This allows a contractor to submit, or GSA to request, a temporary or permanent price reduction at any time.
There are no longer required price reductions based on a BOA discount relationship after the TDR version of the clause applies.
Note: Until the effective date of the “Participate in TDR” modification, contractors remain subject to the applicable non-TDR version of the Price Reductions Clause, either GSAR 552.238-81, Price Reductions, May 2019, or GSAR 552.238-81, Price Reductions, December 2021 deviation. Compliance may be reviewed by an Industrial Operations Analyst, or IOA, or Contract Compliance Analyst during assessments.
Adding products and services to your schedule
At offer and modification submission, supporting documentation, such as invoices, is not required unless the contracting specialist or contracting officer requests it for price analysis.
Vendors do not need supporting documentation, such as invoices, when proposing labor categories after the TDR modification is effective unless the contracting specialist or contracting officer requests it for price analysis under FAR 15.403-1 and GSA Class Deviation RFO-2025-15.
Monthly reporting in the FAS Sales Reporting Portal
MAS-TDR requires monthly reporting through the FAS Sales Reporting Portal, or SRP. MAS-TDR reporting begins on the first day of the quarter after acceptance of the TDR modification.
- Reports are due within 30 calendar days after the end of each month. For example, October sales are due November 30.
- Contractors may report sales based on invoice date or payment date, but they must use the same method consistently.
Industrial Operations Analysts will continue to perform contract assessments to determine whether vendors have accurately reported MAS-TDR data in SRP, with an emphasis on services. Vendors may be required to correct inaccurate data. The IOA will determine the correction timeline.
Industrial Funding Fee
- The Industrial Funding Fee, or IFF, must be remitted quarterly. Contractors may choose to pay monthly.
- Monthly sales reports must include the total price with IFF. Total price is the line item’s price per unit multiplied by the quantity.
- After you submit a sales report, SRP will tell you how much IFF is due.
- FAS SRP does not charge extra fees for credit card payments. Read the fee overview in the user guide for more information.
If you report through SRP Form Entry, SRP automatically calculates the total price in the IFF field.
If you report through the MAS File Upload method, you must manually calculate the total price for each row.
If you already report sales and pay IFF
If you currently report sales and pay IFF under non-TDR reporting, you must:
- Accept the “Participate in TDR” modification.
- Update your process in FAS SRP after the effective date of the “Participate in TDR” modification.
- Report sales monthly, including IFF.
- Continue remitting IFF quarterly, unless you choose to pay monthly.
For more information, see GSAR 552.238-80, December 2025, GSAR deviation.
What sales to report
You must report products and services that are directly linked to your GSA MAS contract. This includes orders made under BPAs awarded under your GSA MAS contract.
Do not report sales from other commercial or government contracts as MAS-TDR sales.
| Report | Do not report |
|---|---|
|
|
Contractor Teaming Arrangements
Each Contractor Teaming Arrangement, or CTA, member is considered a prime contractor. Each CTA member must report the products and services it provides under its own contract number and in accordance with its respective contract terms and conditions.
How contractors submit reports in FAS Sales Reporting Portal
Contractors generally report through one of two methods:
- Form Entry: Used for a small number of orders, line items or zero sales.
- File Upload: Used for multiple orders or line items.
Use the most current Microsoft Excel template from the FAS SRP website each time you report.
If a field does not appear in SRP, you are not required to report it. Make sure you are using the latest FAS SRP upload template.
Required MAS-TDR data fields
MAS-TDR requires data fields that apply to all sales, plus additional fields for products or services. For complete field-level instructions, see Section 4, “MAS-TDR Data Elements,” and Table 4.1, “Data Field Descriptions,” of the MAS-TDR User Guide.
| Data field | Applies to | What to enter |
|---|---|---|
| Contract or BPA number | All sales | Your GSA MAS contract number, which typically begins with “GS” or “47.” Enter a BPA number only when reporting sales under an approved GSA governmentwide BPA. |
| Order number or PIID | All sales | The order number or Procurement Instrument Identifier, or PIID, issued by the ordering agency for each order is usually found in block 4 of SF1449. Alternatively, you can use USAspending to look up awards under your company. As a last resort you can use your invoice number. Do not enter your MAS contract number. |
| SIN | All sales | The MAS Special Item Number under which the product or service was awarded and sold. You can find awarded SINs by searching your contract number in GSA eLibrary search bar, then click on company name. Vendors should reference the original RFQ for the applicable SIN. If an order crosses multiple SINs, select the SIN that represents most of the work, or 51% or more of the total order value. Contact the ordering contracting officer if you need clarification. |
| Non-federal entity | All sales, when applicable | Identify whether the customer is an eligible non-federal entity, such as state or local government. |
| Federal customer | Federal sales | The two-digit Treasury Agency Code of the agency that funded the order. Leave blank if a non-federal entity applies. |
| UCID | Applicable services or items | UCIDs are a unique alphanumeric “”code”” created by the vendor with approved FAS Services Plus Files. Vendors use these codes to identify service line items when reporting sales in GSA systems. UCIDs are helpful if your internal naming conventions differ from your GSA price list, or if you price labor differently based on the worksite (e.g., government site vs. contractor site). You must report the UCID for any service or item that has an established UCID in your FCP file. If the labor category has a valid UCID, enter the UCID exactly as shown in your Services Plus File. If there is no UCID, enter the labor category name exactly as shown on your GSA pricelist. |
| Description of deliverable | All sales | A description of the product or service sold. Requirements vary by reporting scenario. |
| Quantity of items sold | All sales | The number of units, hours or other units sold. |
| Unit of measure | All sales | The applicable unit of measure from your approved catalog file, Services Plus File or Price Proposal Template. |
| Price paid per unit | All sales | The net price for a single product or service unit charged to the customer. |
| Total price paid | All sales | Quantity multiplied by price paid per unit. SRP auto-calculates this field for Form Entry. |
| Manufacturer name | Products | The Original Equipment Manufacturer name must match your approved catalog or Price Proposal Template. |
| Manufacturer part number | Products | The Manufacturer Part Number must match your approved catalog or Price Proposal Template. |
| Universal Product Code | Products, when available | Enter the UPC if available. Leave blank if the product does not have a UPC. Do not enter “N/A.” |
| Order date | Products | The date the order was submitted or signed. |
| Ship date | Products | The date the product or item was shipped. |
| ZIP code shipped to | Products | The five-digit ZIP code for the ship-to location. |
Reporting elements for products
Product reporting depends on whether the product is non-configurable or highly configurable.
Non-configurable products
Non-configurable products are standardized base products, accessories or options with fixed base prices and limited predefined choices.
- Report each unique base product, accessory and/or option on its own line.
- Make sure the Manufacturer Part Number, or MPN, and manufacturer name exactly match your approved catalog.
- Leave the UPC field blank if there is no UPC. Do not enter “N/A.”
- Supporting documentation is not required when line-item detail is provided.
For complete instructions, see Section 3.1.1 (Non-Configurable Products) and Table 5.2, “Reporting Non-configurable Products,” of the MAS-TDR User Guide.
Highly configurable products
Highly configurable products allow customers to select from a range of options, creating a high degree of customization. They are generally awarded and reported in one of two ways.
| HCP path | What it means | Reporting approach | Supporting documentation | MAS-TDR User Guide |
|---|---|---|---|---|
| Path A: Manufacturer product line, series or family | You offer a fixed discount from an entire manufacturer product line, series or family | Report invoice-level detail | Required | More information on reporting for HCP depends on how it is sold as described in Section 3.1.2 (Highly Configurable Products) |
| Path B: Base product with configurations | You offer a base product with additional configurations that determine final price | Report each HCP individually | Not applicable when product-level detail is provided | Complete field-by-field procedures for reporting both paths successfully are provided in Table 5.3 (Reporting Highly Configurable Products) |
Key requirements
- For Path A, upload supporting documentation, such as a bill of materials, invoice or other documentation that provides line-item detail.
- For Path B, report each highly configurable product with its applicable Manufacturer Part Number.
- Leave UPC blank for HCP reporting unless otherwise directed.
- Do not upload classified documentation or sensitive proposal documentation.
- Configurable Services are reported at the line item level to the maximum extent possible, or in alignment with the invoice if line item breakout is not available (which in return requires supporting documentation).
Kits and bundles
If a customer orders products as a kit or bundle, report the products as they are reflected in your approved FCP Product File, including the unit of measure.
Each product must be reported separately to the maximum extent possible regardless of whether the customer orders the part numbers as a “kit”/”bundle”.
Reporting elements for services
Service reporting depends on the type of service, pricing structure and whether line-item detail is available.
Professional services and SCLS services
| Type of service | Pricing structure | MAS-TDR User Guide Reference |
|---|---|---|
| Professional services | Professional services are labor-based services delivered by trained experts in fields such as law, finance, accounting, engineering, architecture, technology, consulting or another specialized field. Professional services are usually priced as fixed or flat fee pricing, hourly pricing or labor-hour pricing. | Section 3.2.1 (Professional Services) |
| Hourly Priced Labor Categories | When reporting hourly priced labor categories:
| Section 3.2.1 (Professional Services) and Section 3.2.2 (SCLS Services) Complete field-by-field instructions are provided in Table 5.5 (Reporting Hourly Priced Labor Categories) |
| SCLS services | Service Contract Labor Standards services are labor-based services subject to applicable Department of Labor wage determinations incorporated into your MAS contract. Reporting requirements for SCLS labor categories generally align with professional services. For SCLS labor categories, include the Wage Determination number and revision number in the required format when applicable. | Section 3.2.2 (SCLS services) |
| Fixed Price Services or Solutions | Fixed-price services or solutions are complete projects, outcomes or deliverable-based offerings sold for a flat fee. They are typically reported in one of two ways:
Key reminders for reporting: Established on your MAS Contract: These are pre-approved solutions from your GSA catalog. They are reported at the line-item level, and supporting documentation is not required if each service or solution is reported at the line item level with its valid UCID and/or manufacturer part number. | Section 3.2.3 (Fixed Price Services or Solutions) Table 5.4 (Reporting Fixed Price Services or Solutions) |
| Configurable Services | Configurable services are non-labor offerings where the final price is based on usage, duration, consumption, number of transactions or similar measures. Examples include:
When reporting configurable services:
| Section 3.2.4 (Configurable Services) Complete field-by-field instructions are provided Table 5.6 (Reporting Configurable/ Miscellaneous Services) |
Common reporting scenarios and topics
What to include in your TDR submission
- You must report products or services that are directly linked to your GSA MAS contract, including orders made on BPA’s awarded under your GSA MAS contract.
- Sales from other commercial or government contracts or orders do not apply.
- Download the most current Microsoft Excel template from the FAS SRP website each time you report. CHeck each time you report to ensure there have been no changes to the template.
- If you are including travel or freight as part of your total pricing report, refer to the Vendor Support Center’s OLM FAQs.
| Scenario | Reporting guidance | MAS-TDR User Guide reference |
|---|---|---|
| Order Level Materials | Report OLMs according to the applicable product or service reporting scenario. If the OLM is purchased from another MAS contractor, the selling contractor reports the sale and pays the IFF. You can find more information about OLM’s here on GSA’s “Order Flexibilities” and on the Vendor Support Center OLM webpage. If the OLM is purchased from another MAS contractor (the selling contractor), that contractor would remit the transactional data, report the sale, and pay the IFF (not the procuring contractor). | Section 3.3.1 (Order Level Materials) on the MAS-TDR User Guide |
| Volume discounts | Follow the MAS-TDR User Guide procedures for reporting volume discounts. | Table 5.7 (Reporting Volume and Prompt Payment Discounts) |
| Prompt payment discounts | Follow the MAS-TDR User Guide procedures for reporting prompt payment discounts. | Table 5.7 (Reporting Volume and Prompt Payment Discounts) |
| Total Price Paid | For File Upload, manually calculate the total price by multiplying price paid per unit by quantity of items sold. For Form Entry, SRP auto-calculates the total price. | Table 4.1 and applicable reporting tables |
| Installment or progress payments | Report sales as invoiced, including quantity and unit of measure. | Applicable reporting table |
| Credits | Follow the instructions in the FAS SRP Microsoft Excel template for returns and credits. | FAS SRP template |
| Returns | Copy the original MAS-TDR data elements and use “RTN” as the unit of measure, with negative quantity and total price values. | Appendix 6.3, “Reporting Returns” |
| Contractor Teaming Arrangements | Each CTA member reports the products and services it provides under its own MAS contract number. | Partner with other MAS contractors |
| Travel and freight | Refer to the Vendor Support Center’s Order Level Materials (OLM) FAQ page if you’re including travel or freight as part of your total pricing report. | Vendor Support Center OLM FAQs |
