GSA pricing map

Part 1

Pricing is the contract story in numbers

GSA pricing is not only about getting a rate accepted. It is about making the commercial story, discount story, catalog story, and reporting story line up.

A good pricing file can be reviewed. A great pricing file can also be maintained after award without the team forgetting what the assumptions meant.

Part 2

Separate proposed prices from pricing support

The proposed price file is the visible offer. Pricing support is the evidence behind it: commercial invoices, market comparisons, labor assumptions, discount logic, catalog data, or other support that explains reasonableness.

This distinction matters because pricing support can answer questions before they become delays.

Part 3

TDR changes the operating rhythm

GSA states that Refresh 31 made TDR mandatory for all MAS SINs. That moves contractors toward monthly line-item reporting and changes how teams should think about sales data ownership.

The practical move is to assign a reporting owner, define the data source, check records before submission, and reconcile IFF obligations on a regular schedule.

Examples

What this looks like in practice

In actionA services firm prices three labor categories

The weak version is a rate table with no story. The strong version connects labor titles, qualifications, duties, commercial rate history, discounts, escalation, and support. The reviewer should understand why each rate belongs on the contract.

  • Name the labor category.
  • Prove the commercial basis.
  • Explain discounts.
  • Keep escalation traceable.
FCP noteOld PPT thinking still helps if you rename the workflow

Contractors still talk about the price proposal template because it was the familiar mental model. In current FCP language, the work splits into Product File and Services Plus File workflows depending on what is being offered.

Frequently asked questions

Is the old price proposal template gone?

The mental model still helps, but current GSA/FCP workflows point contractors toward Product File and Services Plus File resources depending on the offer.

Should MFC and BOA get separate child pages?

Yes. They are important enough for their own pages, especially to distinguish traditional non-TDR obligations from TDR-era reporting.

What is the first deep pricing page to add?

Start with FCP Product File, FCP Services Plus File, TDR, IFF, and pricing support.
