Help with TDR

We post resources to our MAS Interact community and our MAS Office Hours playlist on YouTube.

GSA Interact is an online forum where industry and government can communicate to build more successful business partnerships.

Check your SIN by typing it in the search bar of our MAS TDR table.

We anticipate making TDR mandatory in Q1 fiscal year 2026.

All contracts need to opt-in by Sept. 30, 2025. The mod should be submitted before then.

If any special item number on your contract is subject to TDR, your entire contract will be TDR on the effective date of the Participate in TDR modification, even if you haven’t had work in the SIN.

$0.00 sales reporting is required.

90 days from receipt of the mass modification.

You should opt in to TDR when you submit your MAS offer, removing the need to opt in after your contract is awarded.

Currently, only contractors with mandatory TDR SINs can participate in TDR. Contractors without these SINs continue as-is until we add the remaining SINs in a MAS Refresh in Q1 FY 2026.

TDR reporting is done on a contract basis, so TDR reporting is due for the entire contract.

All of your contracts will be under TDR.

TDR is done on a contract basis, so once in TDR it applies to all SINs under the contract.

Any MAS award and transaction is included in TDR.

It depends on whether shipping is awarded under your contract. If your pricing is Freight on Board — or FOB — origin and shipping is not approved under your MAS contract, the freight would be open market and should be invoiced as such and not reported as a MAS sale.

TDR requires monthly reporting via the FAS Sales Reporting Portal, also called SRP. The monthly reporting period for October is due Nov. 30, and will follow that monthly pattern moving forward. TDR reporting begins on the first day of the quarter following acceptance of the TDR modification. For those joining TDR under Refresh 28, the first day of TDR reporting is Oct. 1, 2025.

The Industrial Funding Fee is remitted quarterly, but you can pay monthly if you prefer.

No. Both TDR and IFF are required. TDR requires monthly reporting, but IFF payments are still made quarterly.

FAS sales are quarterly with no line-item level reporting. TDR is monthly reporting at the line item level with 12 required and four optional data fields.

TDR contractors are only required to report transactions under their MAS Schedule contract.

Refresh 27 had some technical issues, so Refresh 28 was released in its place. You should now have Refresh 28.

No, TDR applies to MAS contracts. It applies to blanket purchase agreements only if the BPAs are awarded against MAS.

TDR allows you to report sales based on either invoice date or payment date.

Ensure the values you entered match exactly with what you had on your catalog. Email TDRteam@gsa.gov for assistance.

If the customer issued a task, delivery order or PIID, use that number. Otherwise, use the invoice number or an internal order number.

Leave the UPC field blank. A UPC is not required.

Yes. Report only transactions under your MAS contract.

Total price is the single line item’s price per unit multiplied by the quantity.

 Leave fields like manufacturer name and manufacturer part number blank.

Report the base model on the first line. Include the various configurations in the description field.

TDR allows reporting based on either the invoice date or the payment date.

As soon as possible after the “Add SIN” modification is approved.

It is mandatory to accept Refresh 28. If your contract includes at least one SIN subject to TDR, you must also submit a modification to participate in TDR.

You should be able to save your progress. Email vsc@gsa.gov if you experience issues.

TDR participants do not need to enter MFC information.

At offer submission, supporting documentation, such as invoices, is not required at offer submission, but the contracting specialist or contracting officer may request it.

TDR applies to the entire contract, so all SINs become subject to TDR requirements.

Include a signed and dated cover letter on company letterhead from an authorized negotiator. The letter should state that you are requesting to participate in TDR and include the required statement for all mods: I certify to the best of my knowledge that the information I provided is current, complete, and accurate. All other terms and conditions remain the same.

TDR removes commercial sales practices, or CSP, and basis of award, or BOA, requirements.

MAS pricing is still negotiated and approved by GSA contracting officers. However, CSP/BOA requirements are eliminated.

Our COs use horizontal price comparisons and Commercial Price Lists, which vendors must still provide.

You will receive a notification email for both when an upload fails as well as when there’s a successful submission.

Reach out to your assigned ACO for assistance.

Contractors must: be a recognized point of contact on the contract, register and activate a multi-factor authentication account with the same email as the contract POC, and be an authorized negotiator, IFF POC, or admin POC. 

Contact our Vendor Support Center at vendor.support@gsa.gov.

The acceptance or rejection process depends on the number of rows in your upload. It can take anywhere from seconds to an hour.

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.

You can download the most current Microsoft Excel template through our FAS SRP website.

The SINs and CLINs you enter for FAS service entries do not have to match what you previously entered in IPP. Your TDR sales report entries must line up with the labor categories, hourly rates, and details on your GSA Advantage postings and approved GSA contract modifications. We want the line item info as shown on your contract.

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.

Use the Adjust Data function in FAS SRP to correct your sales data.

Your course of action depends on whether you are TDR or non-TDR. You report quarterly and monthly sales in FAS SRP. However, if you are now required to participate in TDR, you would need to change your process in FAS SRP.

The instructions in the FAS SRP MS Excel template provide guidance on how to handle returns and credits.
