• Capability Statement

A sources sought notice is a market research announcement that a federal agency posts on SAM.gov before it writes a solicitation. The agency wants to know which businesses can do the work and whether enough small businesses exist to set the contract aside. You respond with a short, tailored letter and your capability statement, sent to the contracting officer before the posted response date. Nothing is awarded from these responses, but they can decide whether the later contract is open only to small businesses.

Which option is right for you?

Your starting point depends on what you already have: a SAM.gov registration, a capability statement, and time to tailor each response.

One line on each: beginners lose the most time by responding before registration is active. Daily users get the most out of a saved search because notices can close in under two weeks. Budget-limited firms can get feedback for free through APEX before paying a consultant.

What Is a Sources Sought Notice?

A sources sought notice (SSN) is a market research tool agencies use to identify capable businesses before deciding how to structure a solicitation. It is not a request for proposals, and it guarantees no future contract. On SAM.gov it is its own notice type. In the official Opportunities API it is coded "r" and labeled "Sources Sought", next to types like Presolicitation ("p"), Solicitation ("o"), and Combined Synopsis/Solicitation ("k") (GSA Opportunities API).

The legal basis is market research under FAR Part 10, and the 2025-2026 rewrite of the FAR changed that part. The older FAR 10.002(b)(2) listed specific techniques. One was "publishing formal requests for information in appropriate technical or scientific journals or business publications" (48 CFR 10.002, Cornell LII). Under the Revolutionary FAR Overhaul (RFO), Part 10 is much shorter. The new 10.001 requires market research before soliciting offers above the simplified acquisition threshold. It tells agencies to have "responsible and constructive exchanges with industry" and to ask for no more than the "minimum information necessary" (Acquisition.gov, FAR Overhaul Part 10). The rewrite also removed the list of techniques and the small business references from Part 10 (PilieroMazza).

As of October 2026, the RFO text works through agency class deviations while formal rulemaking continues. The FAR Council published a second batch of proposed rules on September 18, 2026, and comments closed October 19, 2026 (Nixon Peabody; SBA Office of Advocacy). In practice, the citation printed in the notice you're reading may be either the old or the new number. Both describe the same activity.

For example, a notice might be titled "Sources Sought – Janitorial Services, Building 12" under NAICS 561720. It would describe the scope, list four or five questions, ask for a capability statement of no more than 5 pages, and give a response date. That format is typical, but each agency writes its own.

What Is the Purpose of a Sources Sought Notice?

Agencies post SSNs to measure industry interest, check the NAICS code and size standard, and decide whether a set-aside is feasible. The answers feed a contracting officer's decision that has real legal weight.

The main decision is the Rule of Two. Under RFO FAR 19.104-1(a), a contract above the micro-purchase threshold must be set aside for small business if there is a reasonable expectation of offers "from two or more responsible small business concerns" that are "competitive in terms of fair market prices, quality, and delivery" (Acquisition.gov, FAR Overhaul Part 19). SBA states it plainly: if at least two small businesses could do the work for a fair price, the contract should be set aside for small businesses (SBA, guidance for contracting officials).

SBA also tells contracting officers how to write these notices. They should encourage targeted small business categories (HUBZone, 8(a), women-owned, and others) to respond, "ask only for key pieces of information you need to make the set-aside determination," and include a page limit (SBA). This tells you how your response will be read. The reader is checking capability and status against a decision. They are not scoring marketing copy.

Silence counts against you. In CORE DC, LLC v. United States, a published Court of Federal Claims decision dated August 27, 2026, the court upheld an agency's choice not to set aside a procurement. It noted that "an agency may rationally conclude a non-responding firm is unlikely to submit a proposal" (Government Contracts Legal Forum). In that case, the agency judged the four small businesses that did respond on a specific practical question: whether each could identify an available, properly zoned facility. Generic answers would not have passed that test.

Pitfalls to avoid:

• Assuming someone else will respond. If you're one of only two capable small firms and you stay quiet, the set-aside may not happen.
• Responding to everything. A 2019 Air Force vendor guide warns that sending a generic line card for work you can't do builds a negative image with the agency (summarized by Coley GSA). Respond only where you can do the work, either as a prime or with named teaming partners.
• Ignoring the NAICS code. If the agency picked a code whose size standard excludes you, the SSN response is the place to say so, with reasons.

How to Respond to a Sources Sought Notice

A strong response confirms your socioeconomic status, ties your capability to the stated requirement, and arrives before the deadline. Miss any one of these and you may not be counted. These five steps assume your SAM.gov registration is active.

Step 1: Qualify the notice (15 minutes)

Open the notice on SAM.gov and read these fields first:

1. NAICS Code and the size standard it implies. Check that you're small under that code.
2. Set Aside field. On an SSN it's often blank, because the agency hasn't decided yet.
3. Response Date and its time zone.
4. Attachments/Links. The statement of work, questionnaire, or draft performance work statement is usually attached here, not in the description.
5. Contact Information. The named contracting officer or specialist, and the email address responses go to.

Decision rule: respond if you could perform at least the core work yourself, or with a teaming partner you can name. If you can't, skip it.

Step 2: Copy the agency's questions into your draft

Paste every question or requested item from the notice into a blank document, in the agency's order and numbering. Answer directly below each one. This mirroring approach is widely recommended (GovCon Today), and it fits SBA's guidance that agencies ask only for what they need to make the set-aside call.

Step 3: Write the response letter (use the template below)

Keep to the page limit. If none is stated, 2-5 pages plus a one-page capability statement is a reasonable size, and that is a judgment call, not a rule. Put your status claims (small under the stated NAICS, plus 8(a), HUBZone, SDVOSB, WOSB, or EDWOSB if you hold them) in the first half page.

Step 4: Attach a tailored capability statement

Change the core competencies and past performance on your standard capability statement so they match this scope, then save it as a PDF. Our guide /capability-statement-example-5-sections-buyers-read-first/ explains which sections buyers read first.

Step 5: Submit and confirm

Email (or upload, if the notice names a portal) to the exact address listed. Use the notice ID and title in the subject line, for example: Response to Sources Sought W912XX-26-R-0000 – Janitorial Services – [Company Name]. Save a copy of the sent email with its timestamp, and request a read receipt if your email client supports it.

Sources Sought Notice Template: What to Include

A usable template covers company identification, NAICS and size status, relevant past performance, direct answers to the agency's questions, and a tailored capability statement attached as a PDF. Below is a fill-in layout. The field list draws on common practice (GovCon Today; Coley GSA), and the order puts the set-aside facts where the reader looks first.

[Company letterhead]

Date: [MM/DD/YYYY]
To: [Contracting Officer name], [Agency/Office]
Via: [email address exactly as listed in the notice]
Re: Response to Sources Sought [Notice ID] – [Notice Title]

1. COMPANY IDENTIFICATION
   Legal name: [as registered in SAM.gov]
   UEI: [12 characters]    CAGE: [5 characters]
   Address: [ ]
   Point of contact: [name, title, phone, email]

2. SIZE AND SOCIOECONOMIC STATUS
   Small under NAICS [code] (size standard: [$X million / X employees])
   Certifications: [8(a) / HUBZone / SDVOSB / WOSB / EDWOSB / none]
   Intended role: [Prime / Prime with teaming partner: name, UEI / Subcontractor]

3. ANSWERS TO THE AGENCY'S QUESTIONS
   Q1 [copied text] -> Answer
   Q2 [copied text] -> Answer
   ...

4. RELEVANT PAST PERFORMANCE (2-3 examples)
   Customer | Contract no. | Value | Period | Scope match | Reference contact

5. RECOMMENDATIONS (optional, short)
   e.g., NAICS code fit, set-aside recommendation, unclear requirements

Attachment: Capability Statement (PDF, 1 page)

How each block maps to what the agency is deciding:

Keep Section 5 short. An example of a useful recommendation: "The notice lists NAICS 541512. The described work is mostly help-desk support, which may fit 541519. Both carry the same size standard, so either supports a small business set-aside." Before you write something like that, check the actual size standards in SBA's table.

Your Small Business Search profile also matters, because a CO may check it alongside your response. SBA advises keeping it complete with certifications, a capabilities narrative, keywords, NAICS codes, and performance history (SBA).

Sources Sought Notice vs RFI: What's the Difference?

Both are pre-solicitation exchanges with industry. An RFI usually asks for technical, pricing, or planning input to shape the requirement. An SSN usually screens vendors for capability and socioeconomic status for the set-aside decision. In practice the line blurs. Agencies sometimes post a "Sources Sought/RFI" under one notice type, so read the questions rather than the label.

The regulation is in FAR Part 15. Under the older FAR 15.201(e), RFIs "may be used when the Government does not presently intend to award a contract" but wants price, delivery, market, or capability information for planning. Responses are not offers, and no format is required (48 CFR 15.201, Cornell LII). The RFO renumbers this to 15.101(c), which keeps the rule that the RFI must say the Government won't pay for information or treat responses as offers. RFO 15.101(e) adds an advisory multistep process. In that process, agencies invite capability information and then tell respondents whether they're viable competitors, without blocking them from competing (Acquisition.gov, FAR Overhaul Part 15).

If a notice asks both kinds of question, answer the status and capability items first. Those are what keep you in the count.

What Does 'Sources Sought Notice Only' Mean?

"Sources sought only" means no solicitation exists yet. Responding doesn't put you on a bidders list, and nobody is required to notify you when the solicitation posts. Agencies use the phrase, often with "This is not a request for proposals," to make the status unmistakable.

What it does not mean:

• It doesn't mean the work is reserved for respondents. When the solicitation comes out, any eligible firm can compete, whether or not it answered the SSN.
• It doesn't mean you'll be contacted. RFI-type notices must say the Government won't pay for the information or treat responses as offers (Acquisition.gov, FAR Overhaul Part 15). No rule promises you a follow-up.
• It doesn't mean you need an interested vendors list instead. Some SAM.gov notices let vendors add themselves to an Interested Vendors List when the posting agency has turned that feature on (GovCon Chamber). Adding yourself there is separate from answering the SSN and doesn't replace the emailed response.

For example, if an SSN closes in March and the solicitation posts in July under a new notice ID, you'll only see it if you're watching your saved search or following related notices. The SAM.gov data model links sources sought notices to later presolicitation, solicitation, and award notices (GSA Opportunities API), but you still have to check.

How to Calculate Your Sources Sought Notice Deadline

Deadlines appear as a specific date and time in a named time zone on SAM.gov. Convert to your local time, then set an internal deadline 2-3 business days earlier. The Opportunities API stores this as a response timestamp plus a separate responseTz value, such as America/New_York (GSA Opportunities API). The time zone is part of the deadline, not a footnote. The RFO Part 10 text sets no minimum response period for market research (Acquisition.gov), so windows vary by notice and can be short.

Deadline math, step by step:

1. Copy the Response Date exactly, including the time and time zone.
2. Convert it to your local time zone. Watch daylight saving time. In 2026, DST ends Sunday, November 1, so "ET" before that date means EDT (UTC-4) and after it means EST (UTC-5).
3. Count back business days, skipping weekends and federal holidays. Veterans Day (November 11) and Thanksgiving (November 26, 2026) fall in this window.
4. Set your internal deadline: final PDF approved 2 business days before the cutoff, sent 1 business day before.
5. Check the notice again 48 hours before your internal deadline for amendments. An amended notice can change the date or add questions.

Worked example (sample values): a notice posted Wednesday, October 21, 2026, lists a Response Date of Wednesday, November 4, 2026, 2:00 PM ET, and you're in California.

Pitfalls: reading "2:00 PM" as your local time, sending at 1:58 PM and hitting an attachment size bounce, or missing an amendment that moved the date earlier. After the response date, notices are typically archived 15 or 30 days later, or on a custom date the agency sets. Archived notices stay searchable but are inactive (GSA Opportunities API).

How to Find Sources Sought Notices on SAM.gov

Use SAM.gov's Contract Opportunities search and set Notice Type to Sources Sought. Then narrow by your NAICS code and filter on response date so only open notices show. SAM.gov is where agencies post opportunities over $25,000 and also where they release RFIs and sources sought notices (USDS TechFAR Hub).

Steps (labels as they appear in the search filters, per Winvale and GovCon Chamber):

1. Go to SAM.gov, sign in, and choose Contract Opportunities as the search domain.
2. In the left filter panel, open Notice Type and check Sources Sought. Consider adding Special Notice, because some agencies post market research there.
3. Under the product/service filters, enter your primary NAICS code. Add related NAICS and PSC codes that match your past performance.
4. Expand Dates and set Response/Date Offers Due to today or later, so closed notices drop out.
5. Optional: use Set Aside only on solicitations. On SSNs the field is often empty, so filtering by it hides relevant notices.
6. Sort by response date and save the search. Saved searches for Contract Opportunities offer a Notify option for new matches (DEV Community walkthrough).

Example search set (sample values): Notice Type = Sources Sought + Special Notice, NAICS = 561720 and 561790, Response/Date Offers Due = on or after 10/21/2026, keyword left blank. Try keywords only after the NAICS filter, because titles vary ("custodial" vs "janitorial").

Limitation: SAM.gov's search depends on how the contracting officer coded the notice. A miscoded NAICS will hide it from a strict filter, so run a broader keyword search once a week as a backstop. Paid aggregators exist, but they draw on the same SAM.gov data. They are not for first-time bidders who haven't yet learned the free filters, and their prices change (check each vendor's official page).

Next steps

You can do the next three actions yourself today, and free counseling exists if you want a second pair of eyes.

DIY today:

1. Build the saved search from the previous section and open the three notices closing soonest.
2. Copy the template above into a document, fill in sections 1 and 2 (identification and status) once, and reuse them for every response.
3. Update your capability statement and Small Business Search profile so what you claim matches what the CO can verify.

If you'd rather not do it yourself:

• APEX Accelerators (formerly PTACs) are funded through the DoD Office of Small Business Programs. They offer counseling free or at nominal cost, including bid and proposal review and capability statement help (LaGuardia APEX Accelerator). Good for first-time bidders who want feedback. Less useful if you need someone to write and submit responses for you on a deadline, since counselors advise rather than ghostwrite. Free as of October 2026; check your local center.
• Paid proposal consultants or GovCon writing firms can draft responses for you. They suit firms with steady notice volume and no in-house writer. They're a poor fit if you're still testing whether federal work suits you. Fees vary widely by firm and scope, so ask for a written quote and check the firm's official pricing page.

FAQ

What is sources sought?

"Sources sought" is a federal market research notice in which an agency asks businesses to say whether they can do a planned piece of work. It appears as its own notice type on SAM.gov. Responses help the contracting officer decide on a set-aside, the NAICS code, and the acquisition approach. It is not a solicitation, and nothing is awarded from it.

What is a sources sought announcement?

It's another name for a sources sought notice. SBA uses the term "sources sought announcement" in its guidance to contracting officers (SBA). Some agencies call it a sources sought synopsis. Respond the same way under any of these names.

What is the sources sought notice FAR reference?

Market research falls under FAR Part 10. The pre-overhaul technique list was in FAR 10.002(b)(2), and the RFO version puts the requirements in 10.001. Set-aside decisions that use SSN responses fall under FAR 19.104-1 in the RFO text. RFI rules are in FAR 15.201(e), renumbered 15.101(c) in the RFO.

What does SSN mean in federal contracting?

In federal contracting, SSN usually means "sources sought notice," not Social Security number. Context tells you which. A SAM.gov notice titled "SSN" or "Sources Sought" is the market research notice described here.
