Reading a US federal RFP: Part L, Part M and SAM.gov basics

A quick orientation for first-time federal bidders.

A US federal solicitation (SF-142 / SF-33 package) is built in a fixed order. The sections most likely to win or lose the award are not the statement of work — they are Part L and Part M.

Part A–H: background and boilerplate

Agency details, contract format, place of performance, security requirements, and the usual FAR boilerplate. Read it, but it rarely decides the award.

Part C: Statement of work

What you are actually buying. Important, but price and solution must be mapped to the evaluation criteria — not just the SOW.

Part L: Instructions to offerors

This is the rulebook for how to submit. Format, page limits, number of copies, delivery address, time and time zone, required forms, and registration prerequisites (SAM.gov). Every "must" here is a pass/fail gate.

Part M: Evaluation factors

This is the scoring rubric. Read it before you write a single sentence of the technical proposal. If Part M says "Past performance is more important than technical approach," your proposal must lead with relevant contracts, not your methodology.

SAM.gov registration

You must be actively registered in SAM.gov and have a UEID before submission. Registration can take weeks — start it before you decide to bid.
