To read a government solicitation without getting lost, first work out what kind it is: an RFP (request for proposal), an RFQ (request for quotation) or an IFB (invitation for bid). Then read the parts that decide whether you'll bid, in this order: the cover page, the work, how offers are scored, and what you have to submit. Everything else can wait until you've decided to go for it.

RFP vs. RFQ vs. RFI vs. IFB: what's the difference?

A solicitation is the government's formal request for businesses to bid. The four request types you'll see most work differently:

TypeWhat you sendHow it's decided
RFI (request for information)Answers about your capabilitiesNobody wins. It's market research, and your response isn't an offer.
RFQ (request for quotation)A price quote and any details asked forThe agency places an order with the quote it picks. A contract forms when you accept the order.
RFP (request for proposal)A full proposal: approach, experience, priceOffers are scored against the evaluation factors, and the agency can negotiate.
IFB (invitation for bid)A sealed bid on the government's formBids are opened at a set time and evaluated without discussions. Award goes on price and price-related factors.

The RFQ row surprises people. Under the codified FAR (13.004), "a quotation is not an offer," so the government's order is the offer, and you accept it. An RFP is usually the most work to answer. An IFB is decided on price, so there's no proposal to write, but your bid must conform to the invitation.

Combined synopsis/solicitation. For commercial products and services, agencies can post the announcement and the solicitation as a single notice on SAM.gov. The notice says whether it's an RFQ, RFP or IFB, and the details are in its text and attachments. It's the most common type: on September 25, 2026, FedReady's search of SAM.gov data showed 4,740 open combined synopsis/solicitations and 2,459 standalone solicitations.

Sources sought vs. solicitation. A sources sought notice asks who can do the work before the agency decides how to buy it. It isn't a solicitation, so answering one can't win you a contract, but it can shape what comes next. See how to find government contracts for every SAM.gov notice type.

Start with the cover page

The first page tells you, in about a minute, whether to keep reading. On a commercial buy it's usually Standard Form (SF) 1449. On other solicitations it's Section A. Look for four things:

  • Solicitation number. This is the unique ID for the buy, and you'll put it on everything you send. Most follow a standard federal pattern (not counting dashes): the first six characters identify the buying office, the next two are the fiscal year, and the ninth character shows the type. R means RFP, Q means RFQ and B means IFB.
  • Set-aside, NAICS code and size standard. On the SF 1449, block 10 says whether the buy is unrestricted or set aside for small business, HUBZone, SDVOSB, WOSB, EDWOSB or 8(a). It also lists the NAICS code and size standard. If you don't qualify, stop here. See set-aside contracts explained.
  • Due date and time. Block 8 on the SF 1449 gives the offer due date and local time.
  • Contact. The contracting officer or contract specialist named here is who you send questions to.

How a solicitation is organized: sections A to M

Many solicitations, especially larger non-commercial RFPs, use the uniform contract format. It has 13 lettered sections: A (form), B (prices), C (description of the work), D (packaging), E (inspection), F (delivery or performance), G (contract administration), H (special requirements), I (clauses), J (attachments), K (representations and certifications), L (instructions to offerors) and M (evaluation factors).

Commercial buys usually use the SF 1449. Its full name is Solicitation/Contract/Order for Commercial Products and Commercial Services. Under the FAR overhaul text, commercial solicitations use the SF 1449, the SF 18 or a similar form, and they're often shorter than a full A-to-M solicitation. Their instructions usually sit in FAR 52.212-1 (Instructions to Offerors) plus any addendum, and their evaluation factors in FAR 52.212-2 or an addendum. Treat those as your Sections L and M. The form itself says the offeror completes blocks 12, 17, 23, 24 and 30: discount terms, your company details, unit prices, amounts and signature.

How to read an RFP: the reading order

Before you start, check the notice for amendments and make sure you're reading the latest version of everything. Then read in this order:

OrderSectionWhat you're checking
1Cover page (A or SF 1449)Set-aside, NAICS, due date, time zone
2C: the workCan you do it, at that place and scale?
3M: evaluationLowest price or best value? What counts most?
4L: instructionsWhat to submit, page limits, format, delivery method
5B: pricesLine items, quantities, base and option years
6F: performanceStart date and length
7J: attachmentsWage determination, drawings, pricing sheets
8H and I: requirements and clausesLicenses, insurance, bonds, special terms
9K: reps and certsMostly covered by your SAM.gov registration

Leave D, E and G until you've decided to bid. For Section K, the standard provision lets you rely on the reps and certs in your SAM.gov registration, which you confirm by submitting your offer, so keep them current.

Section C: SOW vs. PWS

Section C describes the work, as either a statement of work (SOW) or a performance work statement (PWS). A SOW often spells out how the work should be done. A PWS describes the results the agency wants, rather than how to do the work or how many hours to spend, and it sets measurable standards.

Read it as the person who'd do the job. Mark every location, quantity, frequency, staffing rule and deliverable. If you can't picture doing the work well at a price that makes sense, stop here.

Sections L and M

Section L says what to submit and how: volumes, page limits, fonts, file types and where to send it. Section M says how offers will be scored. Read M first so you know what matters, then use L to build your response.

Section M usually follows one of two approaches:

  • Lowest price technically acceptable (LPTA): the lowest-priced offer that meets the standards wins.
  • Best value tradeoff: the agency can pay more for a stronger proposal. Section M tells you how the non-price factors weigh against price.

Follow Section L exactly, in its order and with its headings. Evaluators look for what it asks for, where it asks for it.

Attachments and wage determinations

Section J lists the attachments, and they often hold the most important details: drawings, site maps, workload data, pricing sheets and the wage determination. A wage determination sets the minimum wages and fringe benefits for workers on the contract. The Department of Labor sets them, and SAM.gov publishes them. The Service Contract Act covers service contracts over $2,500, and Davis-Bacon covers construction contracts over $2,000. Treat those rates as your floor when you price.

Amendments, questions and deadlines

Amendments

An amendment changes the solicitation: a new due date, answers to questions, a revised work statement. Amendments often come on SF 30 and are posted to the solicitation's notice on SAM.gov, so follow the notice.

You must acknowledge every amendment by the date and time it gives. The usual ways are signing and returning the SF 30 or listing the amendment number and date on your offer. For sealed bids, a missed acknowledgment is excused only if the amendment is minor or your bid clearly shows you received it. Don't count on that.

Questions

Each solicitation sets its own deadline for questions. There's no FAR-wide default, so find the date and put it on your calendar. Send questions in writing to the named contact. For sealed bids, the FAR says oral explanations given before award "will not be binding," and material answers go to all bidders as an amendment. Ask early, because the answers may change your price.

Deadlines and time zones

Read the due date and time twice. Deadlines are usually in the buying office's local time, which may not be yours. If a proposal solicitation gives no time, the FAR default is 4:30 p.m. local time at the office that receives proposals.

Go or no-go: a checklist before you respond

  • You qualify for the set-aside, and you're small under the NAICS code's size standard.
  • Your SAM.gov registration will be active when you submit and at award.
  • You can do the work in Section C, at that location and scale.
  • You can meet the start date and any license, insurance or bonding requirements.
  • You can price competitively using the wage determination.
  • You can score well on the factors Section M weighs most.
  • You have time to write a response that follows Section L before the deadline.
  • You have relevant experience. On proposals evaluated under FAR Part 15, an offeror with no past performance can't be rated favorably or unfavorably on it.

If most boxes are checked, go. If not, pass and save your time for a better fit.

How to respond to a solicitation

  1. Download everything: the solicitation, every attachment and every amendment.
  2. Build a compliance list from Section L (or the commercial instructions): every document, form, signature and page limit.
  3. Send questions before the question deadline.
  4. Write to Section M. Put your strongest proof on the factors that count most.
  5. Price from the work statement and wage determination, using the line items in Section B or the SF 1449 schedule.
  6. Complete the forms and acknowledge every amendment. On an SF 1449, that means blocks 12, 17, 23, 24 and 30.
  7. Check your SAM.gov registration is active and your reps and certs are current.
  8. Submit early, by the method the solicitation names, and keep proof.

Frequently asked questions

Is an RFQ easier to answer than an RFP?

Often, yes. An RFQ asks for a price quote and usually less writing, while an RFP asks for a full proposal scored on several factors. Read the evaluation criteria either way, because some RFQs also ask for technical details.

What does a solicitation number mean?

It's the unique ID for a solicitation, shown on the cover page. Most follow a standard federal pattern in which the first six characters identify the buying office, the next two are the fiscal year, and the ninth character shows the type: R for an RFP, Q for an RFQ and B for an IFB.

Do I have to respond to every section of a solicitation?

No. You have to provide everything the instructions ask for, usually in Section L or the commercial instructions. Other sections describe how the contract will work. They become part of your contract if you win, so read them before you submit.

What happens if I miss an amendment?

Your offer can be rejected. Solicitations require you to acknowledge each amendment by its deadline, and for sealed bids a missed acknowledgment is only excused when the amendment is minor or your bid shows you received it.

Can I call the contracting officer with questions?

Follow the solicitation's instructions, which usually ask for written questions by a set date. For sealed bids, the FAR says oral explanations before award aren't binding, so get your answers in writing.
