Part 1

Specific templates exist for a reason

Some SINs have pricing models that do not fit a simple product or labor-rate table. Relocation, lodging, travel, logistics, vehicle leasing, courier, package delivery, and air charter services can need different data structures.

The special workbook is not busywork. It is the model GSA expects reviewers to use for that offering lane.

Part 2

Refresh 32 examples from the supplied files

The supplied 4PL workbook includes discount and markup product tabs plus options and product/accessory relationships. The supplied 531 relocation workbook has multiple service tabs and repeats the note that proposed pricing should include IFF. The supplied 531110 lodging workbook highlights geographic coverage, fee waivers, and property addresses.

Those examples show why a generic pricing page is not enough for every SIN.

Part 3

Use this page as a selector seed

This guide is also the natural content base for a future SIN selector. The selector can ask what the contractor sells, identify candidate SINs, then point to the correct template and support guide.

Examples

What this looks like in practice

In practiceA team picks SINs before opening pricing files

Instead of starting with a generic price table, the team confirms the selected SINs against the MAS Available Offerings list and GSA required-template page. That tells them whether they need a special workbook for 4PL, relocation, lodging, travel, ground transportation, delivery, vehicle leasing, courier, or air charter.

  • Confirm SIN.
  • Check required templates.
  • Download current workbook.
  • Map special fields.
  • Tie support to each tab.

Frequently asked questions

Should every listed SIN template get a separate page?

Eventually, yes for high-value templates. This milestone starts with a consolidated guide so the structure is correct before expanding into individual template pages.

Where do I find the live template?

Use GSA's required templates page and confirm the selected SIN against the current MAS offerings list.

Can a SIN-specific template replace pricing support?

No. It structures the proposed pricing. Pricing support still needs to explain the basis and reasonableness of those prices.
