What It Is
Section L is the government's instruction manual for how to write and submit your proposal. Under FAR 15.204-5(b) it tells offerors how to organize the proposal — the volumes and sections to include (typically a technical volume, a past-performance volume, and a price volume), the page limits, the fonts and margins, the file formats, the number of copies, the submission method and portal, and the exact due date and time. It may also state the conditions and notices that govern the competition: whether the government intends to award without discussions, how questions will be handled, and how proposals will be treated. Section L is paired with Section M: L tells you how to present your proposal, and M tells you how it will be scored. The cardinal rule of Section L is literal compliance — evaluators typically read only what you were told to submit, in the order and within the limits you were told to use, and a proposal that violates a material Section L instruction can be found unacceptable or have the offending pages ignored before the technical team ever weighs its merits.
What’s In It
- The required proposal volumes and their contents (technical, past performance, price).
- Page limits, formatting rules (font, margins, spacing), and file-format requirements.
- The submission method, portal, number of copies, and the exact due date and time.
- Notices about the competition — e.g., intent to award without discussions.
- Instructions on how and when to submit questions.
What Goes Here
| Component | What It Means |
|---|---|
| Proposal organization | Section L dictates the volumes and the order of contents. Mirror its structure exactly so evaluators can find each required element where they expect it. |
| Page limits and format | Page limits, fonts, and margins are usually enforced strictly. Pages over the limit may be discarded unread, and wrong formatting can make your proposal noncompliant. |
| Submission mechanics | The portal, file format, number of copies, and due date and time are pass/fail. A late or misformatted submission can eliminate an otherwise winning proposal. |
| Cross-walk L to M and C | What Section L tells you to write is what Section M scores and what Section C requires. Build a compliance matrix mapping each Section L instruction to your response and to the Section M factors. |
What It Means for an SDVOSB
Section L is where disciplined SDVOSBs beat bigger, sloppier competitors — and where undisciplined ones eliminate themselves. Because evaluators generally read only what Section L asks for, in the order and within the limits it sets, a small firm that follows the instructions to the letter presents a proposal that is easy to evaluate and hard to mark down on compliance. Build a compliance matrix that maps every Section L instruction to a place in your proposal and to the corresponding Section M evaluation factor, so nothing required is missing and nothing scored is buried. Respect page limits and formatting rigidly; a strong technical approach on page 51 of a 50-page limit is simply not read. And treat the submission mechanics — portal, format, copies, and the exact due time — as pass/fail, because the most common way small businesses lose winnable set-asides is a late or nonconforming submission, not a weak solution.
Watch Out For
- Exceeding page limits — over-limit pages are commonly discarded unread.
- Reorganizing the proposal your own way instead of following Section L's structure, so evaluators cannot find required content.
- Missing the submission method, file format, or number of copies — pass/fail mechanics.
- Submitting after the exact due date and time — late is late, and it eliminates you.

Frequently Asked
What is Section L of a solicitation?
Section L, under FAR 15.204-5(b), is the instructions, conditions, and notices to offerors — the government's manual for how to prepare and submit your proposal. It specifies the required volumes and their contents, page limits, formatting rules, file formats, number of copies, the submission portal and method, and the exact due date and time. It also states notices such as whether the government intends to award without discussions. Section L is paired with Section M, which explains how the proposal will be evaluated. Following Section L exactly is essential, because non-compliant proposals can be eliminated.
What is the difference between Section L and Section M?
Section L tells you how to write and submit your proposal — the volumes, page limits, format, and deadline. Section M tells you how your proposal will be evaluated — the factors, subfactors, and their relative importance, and whether the award is best-value tradeoff or lowest-price technically-acceptable. You write your proposal to both at once: Section L governs presentation and compliance, and Section M governs substance and scoring. The winning technique is a compliance matrix that maps each Section L instruction to the Section M factor it supports.
