Transactional Data Reporting requirements
Effective with Refresh 31, Transactional Data Reporting, or TDR, is mandatory for all Multiple Award Schedule SINs.
TDR is our way of collecting data about the prices paid for products and services sold through MAS and helps us better understand what the government purchases. Under these requirements, vendors must report transactional data from orders placed against MAS and other governmentwide acquisition contracts.
You will report line item data on up to 16 elements each month
Use our Sales Reporting Portal to report this data:
Note: There are specific product fields that do not apply for services. See the table below for a comparison of the fields.
| Products | Services |
| 1. Contract or blanket purchase agreement number 2. Delivery, task order number, or procurement instrument identifier 3. Special item number 4. Description of deliverable 5. Unit measure 6. Quantity of item 7. Price paid per unit 8. Total Price 9. Non-federal entity 10. Federal customer* 11. Order date* |
*Indicates optional fields.
For detailed instructions on TDR requirements based upon type of product/service (for example, standard COTS product versus Highly Configurable Product or fixed price services versus hourly rate) see the MAS File Upload Instructions in the FAS SRP User Guide.
Things to keep in mind
New MAS offerors
- Participation in TDR is mandatory for offers / resultant contractors under all SINs under GSA MAS Solicitation 47QSMD20R0001. TDR currently does not apply to VA Schedule contracts.
- Due to system restrictions, offers under non-TDR terms and conditions cannot change their offer to TDR. As a result, if you are a non-TDR offer, you should withdraw and resubmit your offer under TDR, or the offer will be rejected.
Existing MAS contractors under Non-TDR
- You will receive a Participate in TDR mass modification which is distinct from the standard Refresh mass modification. First accept the Refresh 31 mass modification, then accept the Participate in TDR modification. These steps should be taken as soon as possible.
- Non-TDR requirements will continue to apply until the effective date of the Participate in TDR modification.
- If you have and/or intend to hold continuous contracts — where you leave the existing contract open for a finite period of time to accommodate active BPAs and also have a surviving/new MAS contract — you must have the same TDR status for both contracts.
