Help with TDR
Basics
How do I find TDR resources?
We post resources to our MAS Interact community and our MAS Office Hours playlist on YouTube.
What is GSA Interact?
GSA Interact is an online forum where industry and government can communicate to build more successful business partnerships.
How do I get TDR training?
Watch for events on our MAS Interact community. Email maspmo@gsa.gov with questions. Ensure that you are signed up for TDR Monthly Office Hours (beginning June 2026). You can also refer to previous office hours sessions available on MAS Interact:
Mandates and requirements
When is TDR mandatory?
As of Refresh 31, which was released on April 2nd 2026, TDR is mandatory for all MAS SINs.
What do I do if my contractor has not yet opted into TDR?
You must accept the Participate in TDR modification as soon as possible after receipt but no later than 60 days after receipt. The MAS Refresh 31 modification should be accepted first followed by the Participate in TDR modification.
Should my total pricing report include travel or freight?
Please refer to the OLM FAQ page on vsc.gsa.gov.
Monthly TDR reporting
What is the due date for monthly reports under TDR?
TDR requires monthly reporting via the FAS Sales Reporting Portal, also called SRP. TDR reporting begins on the first day of the quarter following acceptance of the TDR modification. The contractor must report sales within 30 calendar days from the last calendar day of the month. For example: The sales for the monthly reporting period for October are due November 30th, and will follow that monthly pattern.
How often is the IFF payment required?
The Industrial Funding Fee payment must be remitted quarterly, but you can pay monthly if you prefer. Note: While IFF payment is required to be remitted quarterly, the monthly sales reporting must include total price with IFF.
Will TDR replace current FAS reporting?
TDR is an additional requirement that involves monthly, line-item–level transactional data reporting, whereas traditional FAS sales reporting is quarterly and does not require line-item detail.
Does a contractor need to report commercial sales?
TDR contractors are only required to report transactions under their MAS contract.
Does TDR apply to all GSA contracts?
No, TDR applies to MAS contracts and other applicable GSA/FAS IDVs. It applies to blanket purchase agreements only if the BPAs are awarded against MAS.
Are sales based on invoice or payment date?
TDR allows you to report sales based on either invoice date or payment date.
What do I do if I receive a non-compliance report or encounter errors when submitting my monthly report?
Ensure the values you entered match exactly with what you had in your catalog. You can reference the 2026 industry training slidedeck (linked at the top of the page), which goes into each reporting field in detail. You may also email TDRteam@gsa.gov for assistance.
Who reports what in a Contractor Teaming Arrangement?
Each Contractor Team Arrangement member is considered a prime contractor and must report the products and services that they provide under their contract, in accordance with their respective contract terms and conditions.
Data fields and reporting elements
What should I enter for Contract Number/BPA Number
Use your MAS contract number unless you are reporting sales under the SCRIPTS BPA, in which you would use your BPA number for that program.
What order/PIID number should I use for TDR reporting
If the customer issued a task order, delivery order, or a PIID, use that number. Otherwise, use the invoice number or an internal order number. See the industry training slidedeck linked at the top of this page for more information.
What if there is no Universal Product Code?
Leave the UPC field blank. A UPC is not required.
Are we only reporting GSA transactions with TDR?
Yes. Report only transactions under your MAS contract. This includes BPAs awarded against MAS contracts.
What does “total price” refer to in TDR reporting?
Total price is the single line item’s price per unit multiplied by the quantity. This includes the IFF.
What if my contract only covers services?
To prevent submission errors when entering data directly into the form, you must leave the entire product row blank. This requirement does not apply when submitting data via file upload.
How do I report a highly configurable product?
There are two ways to report a highly configurable product where there are too many configurations to provide all items on the Services Plus File (SPF). You can either report by manufacturer/product line/ family/series/etc, which requires the contractor to upload an invoice or bill of materials that breaks down the different configurations purchased, OR by base model and include various configurations in the description. See the FAS SRP User Guide for additional information.
Note: A product with options and/or accessories is not considered highly configurable for the purposes of reporting if each option and/or accessory can be listed on the Product File or Services Plus File (as applicable)
When should I report sales under TDR reporting?
TDR allows reporting based on either the invoice date or the payment date.
How do I report Firm Fixed Price Services?
Report Firm Fixed Price service descriptions precisely as they appear on the invoice, or alternatively provide higher quality descriptions than invoiced. Separate line items on the invoice should be reported individually with bundled services reported as a single aggregate line item. (i.e. match your invoice reporting line method). Report the unit of measure as invoiced.
File Upload Note: Firm Fixed Price Services and SCLS order types above $1 million (total contract value), you must upload a PWS/SOO/SOW one time upon initial task order award in SRP. Documents containing Controlled Unclassified Information (CUI) are allowable as SRP system encrypts upon upload, however do not upload classified documents. See the industry training slidedeck linked at the top of this page for more information.
How do I report Labor Hour and Time & Material services?
Report standard hourly labor rates for each Labor Category Title (LCAT) by entering the exact Unique Catalog Item ID (UCID) associated with the LCAT to match your internal LCAT to your approved GSA LCAT. If your company is not in the FAS Catalog Platform yet, please match your exact labor category name from your pricelist in the Description of Deliverable field. Once you join the FAS Catalog Platform and establish UCID’s, begin to report the UCID instead of exact matching in the Description of Deliverable field. Use “HR” as the unit of measure for standard hourly labor and “OT” for non-standard and premium hourly labor. For non-hourly components such as materials, report the service as it is invoiced for the unit of measure and “Description of Deliverable”. See the industry training slidedeck linked at the top of this page for more information.
How do I report Hybrid Orders that have a mix of FFP, LH, and/or T&M CLINs?
Report each CLIN separately according to its contract type. Do not combine FFP, LH, and/or T&M CLINs as a single line item in SRP. Vendors can select the applicable type in the “Order Type” field for each line item when the field becomes available in SRP.
How do I report sales for installment or progress payments?
Installment or progress payments typically only apply to Firm Fixed Price Services orders, as labor hour and time & material orders are unit based. It is important to report sales as you have invoiced the customer, to include the unit of measure.
What is a Unique Catalog Item ID (UCID) and do I need to report the UCID?
A UCID is a code created by vendors with published pricelists on the Federal Catalog Platform (FCP) Services Plus File (SPF) that links their services, products, internal labor categories to their official labor category titles or products on their published pricelist. UCIDs are useful for all catalog types, but they are especially helpful for vendors whose internal naming conventions differ from their GSA pricelist, or for vendors that price labor differently based on worksite (e.g. Government Site vs Contractor Site). While UCIDs required for Labor Hour and Time & Material orders (not Firm Fixed Price). If you are offering products or services on the Services Plus File in FCP, the UCID should be reported.
How do I report Labor Category (LCAT) Titles?
Match published GSA Price List / Catalog labor category names exactly OR input an FCP UCID to match the labor categories. Abbreviations, internal naming conventions, or modified titles are not acceptable unless the vendor utilizes the FCP UCID.
What are Order Level Materials (OLMs) and should they be reported?
OLMs are products, services, and/or solutions (a combination of products and/or services) acquired in direct support of an order placed against a FSS contract, including orders under FSS BPAs, when the products, services, and/or solutions are not known at the time of FSS contract or FSS BPA award. OLM pricing is not established in FSS contracts or FSS BPAs.
All sales of items classified as OLMs must be specifically reported under the OLM SIN and the “Description of Deliverable” field should be reported as invoiced to the customer. Exception: If the OLM is purchased from another MAS contractor (the selling contractor), then the selling contractor would remit the transactional data (report the sale and pay the IFF) not the procuring contractor.
How do I find the SIN number applicable to my order?
For a list of awarded SINs on your contract, enter your contract number on the GSA eLibrary search bar. Vendors should reference the original RFQ for the applicable SIN. If the order crosses multiple SINs, select the SIN that represents the majority of the work. Contact the Ordering Contract Officer for clarification on the applicable SIN if necessary.
How do I report the “Federal Customer” and “Non-Federal Entity” fields?
When selling to a federal agency, enter the two-digit Treasury Agency Code. A list of codes is available on the FAS SRP User Guide. When selling to a state/local government or Non-Government Organization, you can choose SCP (State/Local Cooperative Purchasing), SDP (State/Local Disaster Purchasing), OTH (Other Non-Federal Entity), or N/A (Not Applicable indicating that the customer is a Federal Government Entity.
How do I report the Worksite field?
Enter one of three options for where the work was performed related to the line item: Contractor Site, Government Site, or Virtual/Remote. If work was performed at multiple sites during the monthly reporting sales period, enter the predominant worksite in which the majority of the work was performed.
Modification process and requirements
Refresh 31 acceptance and TDR participation
It is mandatory to accept the TDR Mass Mod associated with Refresh 31 as soon as possible but no later than 60 days after receipt of the modification
If I am having issues accepting the “Participate in TDR” Mass Mod and/or the Refresh 31 Mass Mod, who do I contact?
Email vsc@gsa.gov if you experience issues.
If I am TDR, do I need to complete the Most Favored Customer columns of the FCP File/Price Proposal Template (PPT)
TDR participants do not need to enter MFC information.
How does TDR affect adding new products and services to my schedule?
At offer and modification submission, supporting documentation, such as invoices, is not required, but the contracting specialist or contracting officer may request if they determine it is necessary to complete their price analysis.
Impact on pricing and commercial sales practices
What requirements does TDR eliminate?
TDR removes commercial sales practices, or CSP, and basis of award, or BOA, requirements.
Does the Price Reduction Clause apply
Prior to MAS refresh 31 there was a TDR and non-TDR version of the Price Reductions Clause. As of MAS Refresh 31 and upon the effective date of the Participate in TDR modification, Price Reduction Clause GSAR 552.238-81 (DEC 2025) (GSAR DEVIATION) applies. This allows for a contractor to submit or GSA to request a price reduction (temporary or permanent) at any time. There are no longer “required price reductions” based upon a BOA /discount relationship.
NOTE: Until the effective date of the Participate in TDR modification, contractors are still held to the non-TDR version of the Price Reductions Clause GSAR 552.238-81 Price Reductions (MAY 2019) or GSAR 552.238-81, PRICE REDUCTIONS (DEC 2021) (DEVIATION), as applicable. Compliance may be reviewed by the Industrial Operations Analyst /Contract Compliance Analyst during assessments.
Am I still required to provide supporting documentation for Labor Category offerings?
Vendors do not need supporting documentation, such as invoices, when proposing labor categories after their TDR modification is effective. However, the CS/CO can request supporting documentation for price analysis as deemed necessary following FAR 15.403-1 (GSA Class Deviation RFO-2025-15).
FAS SRP and technical issues
What if a particular field does not appear in SRP when reporting sales?
If a particular field is not available in SRP, you are not required to report it. Additional data fields outlined in the 2026 Industry Training slidedeck, linked at the top of this webpage, provide more insight on the requirements associated with these fields that will be added over time. Ensure you are using the most up to date FAS SRP upload template when reporting TDR.
Do I get notified if my submission is successful or rejected?
You will receive a notification email for both when an upload fails as well as when there’s a successful submission. You may be asked to update some data fields that flag a potential error, however it will not prevent you from overall submitting your sales reporting.
How do I add a new SRP user?
Updates to the Contractor Point of Contact (POC) require a contract action within the contracting system. Please contact your Procuring Contracting Officer (PCO) or Administrative Contracting Officer (ACO) to initiate any changes.
What eligibility requirements are there to access the SRP?
Requirements:
- Must be listed on the contract in one of these roles: IFF POC, Administrative Rep, or Authorized Negotiator.
- Use the email address listed on the contract file to register.
- Ensure access by logging in at least every 90 days.
Instructions:
- Go to the FAS SRP website https://srp.fas.gsa.gov/.
- Click on ‘Register’.
- Enter your email address and follow the prompts.
- Log in using your credentials.
How do I regain access or merge SRP accounts?
Contact our Vendor Support Center at vendor.support@gsa.gov.
SRP process timeframe
The acceptance or rejection process depends on the number of rows in your upload. It can take anywhere from seconds to an hour.
IFF calculation
IFF calculation The SRP will tell you how much IFF is due after you submit a sales report. Read our FAS SRP GSA User Guide’s fee overview for more information.
What is the right template to use?
You can download the most current Microsoft Excel template through our FAS SRP website. Make sure to check each time you report to ensure there have been no changes to the template.
How do I address an FAS SRP indicating “cannot find items”?
You may be getting an error because the value entered does not match exactly with what you had on your catalog. Please reach out to TDRTeam@gsa.gov with questions.
How do I correct data submitted in the wrong reporting period?
Use the Adjust Data function in FAS SRP to correct your sales data.
How do I enter negative dollar amounts?
FAS SRP accepts negative values for both Quantity of Items Sold and Total Price. Negative values should be used for returns with products only. This information is in the FAS SRP User Guide
Will IOAs/CCAs still perform Contract Assessments?
IOA’s will continue to determine if vendors have accurately reported TDR data in SRP, with an emphasis (for services) on correct units of measure, “Description of Deliverable”, and Special Item Numbers (SINs). Vendors may be required to update incorrect data submitted, with the IOA using their judgement to determine the date in which corrections must be made.
Industrial Funding Fee under TDR?
If I am currently non-TDR, how does Refresh 31 impact me if I am already reporting sales and paying the IFF?
You must accept the “Participate in TDR” modification. Upon the effective date of the Participate in TDR, you will need to change your process in FAS SRP. You will be required to report your sales (including IFF) monthly. IFF payments will still be due quarterly. Reference GSAR 552.238-80 (DEC 2025) (GSAR DEVIATION) for details.
How do I report credits?
The instructions in the FAS SRP MS Excel template provide guidance on how to handle returns and credits.
Are there charges for paying IFF via credit card?
No. FAS SRP does not charge extra fees for credit card payments.
