RFI vs RFQ vs RFP: How Federal Response Deadlines Differ
Open SAM.gov on any weekday and you will see notices labeled Sources Sought, Request for Information, Presolicitation, Combined Synopsis/Solicitation, and Solicitation. Many small contractors treat them all the same way: skim the title, note the date, and decide later. That habit costs bids. Each notice type runs on its own clock, carries a different penalty for missing it, and signals a different stage of the buy. Once you know which clock you are looking at, you can decide in minutes whether a notice goes on your calendar, and how much lead time you actually have.
This guide walks through the four notice types that matter most for deadline planning, the response windows you can typically expect for each, and a simple calendar system that keeps an RFI from quietly turning into an RFP you never saw coming.
The Four Notice Types in Order
Federal buys usually move through a predictable sequence. Not every acquisition uses every step, but the order rarely changes.
| Notice | What the agency is doing | Typical response window | Is the deadline binding? |
|---|---|---|---|
| Sources Sought / RFI | Market research: who can do this, is a set-aside justified, is the requirement realistic? | Often 7–15 calendar days | Soft. A late reply is rarely accepted, but no award is lost directly. |
| Presolicitation (synopsis) | Public notice that a solicitation is coming | No response required; usually posted at least 15 days before the solicitation for larger buys | No, but it starts your prep clock. |
| RFQ (Request for Quotation) | Simplified acquisition or a buy against a schedule or vehicle; price and basic technical fit | Frequently 5–15 days, sometimes shorter | Yes in practice. Late quotes are usually not considered. |
| RFP (Request for Proposal) | Negotiated procurement with written evaluation factors | Commonly 30 days or more for buys above the simplified acquisition threshold; 45+ for many R&D efforts | Hard. Late proposals are rejected except under narrow FAR exceptions. |
These windows are patterns, not guarantees. Commercial-item buys issued as a combined synopsis/solicitation can legally run shorter, and urgent requirements compress everything. The date printed in the notice always controls.
Sources Sought and RFIs: The Deadline Most Firms Skip
An RFI response is not an offer, and the government cannot award a contract from it. That is exactly why many contractors ignore these notices, and why ignoring them is a mistake. Contracting officers use sources sought responses to decide whether to set a requirement aside for small business. The "rule of two" asks whether at least two capable small businesses are likely to submit offers at a fair price. If only one small firm answers the sources sought, the requirement may go full and open, and you end up competing against large primes on a contract that could have been reserved for firms your size.
Practical rules for RFI deadlines:
- Treat the RFI date as a real deadline. Put it on the calendar the day you see the notice, with a reminder three business days out.
- Answer only what was asked. A tight three-to-five page response with relevant past performance, your size status under the listed NAICS code, and your set-aside certifications beats a 30-page brochure.
- Log the notice ID. The eventual solicitation often reuses or references the RFI's notice ID or title. Keeping it lets you connect the two when the RFP posts weeks or months later.
- Ask your questions now. RFIs are the cheapest point to influence scope, contract type, and even the response window of the future solicitation.
RFQs: Short Windows and Price-First Decisions
RFQs show up in simplified acquisitions and in orders placed against GSA Schedules, BPAs, and other vehicles. Under FAR Part 13, a quotation is not an offer, but that does not soften the clock. Windows of five to ten days are common, and orders under existing vehicles sometimes allow only a few business days. On GSA eBuy, you will only see RFQs for the Special Item Numbers on your schedule, so the notice may never appear on SAM.gov at all.
Because RFQ windows are short, the go/no-go decision has to happen within 24 hours of posting. Keep a pre-built quote package ready: current pricing, a one-page technical approach per service line, your UEI and CAGE code, and a signed standard cover letter you can adapt.
RFPs: The Hard Deadline and What Happens If You Miss It
An RFP deadline is the one you cannot recover from. Under FAR 15.208, a proposal received after the exact time specified is late and generally will not be considered. The main exceptions are narrow: for example, an electronic proposal received at the government's initial point of entry by 5:00 p.m. one working day before the due date, or a proposal that was demonstrably under government control before the deadline. Do not plan around exceptions.
RFPs also contain several deadlines, not one:
- Questions due. Often 7–14 days after release. Miss it and you lose your only chance to clarify ambiguous requirements.
- Site visit or pre-proposal conference registration. Sometimes mandatory. Check Section L or the cover letter.
- Amendment acknowledgments. Every amendment must be acknowledged, usually on the SF-30 or in the block provided on the SF-33 or SF-1449. An unacknowledged material amendment can make your proposal nonresponsive.
- Proposal due date and time. Note the time zone. It is the contracting office's local time unless stated otherwise, which is not always Eastern.
Build a Deadline Calendar That Follows the Buy
The goal is to track acquisitions, not individual notices. Here is a workable routine for a one- or two-person capture team:
- Save searches by NAICS and notice type. In SAM.gov, save separate searches for sources sought and for solicitations under each of your primary NAICS codes, and turn on daily email notifications.
- Create one tracker row per acquisition. Columns: agency, notice ID, notice type, questions due, response due (with time zone), set-aside, and a status field.
- Set back-scheduled reminders. For RFPs, use T-21, T-14, T-7, and T-3 days. For RFQs, use T-3 and T-1. For RFIs, use T-5 and T-2.
- Check for amendments every business day. Amendments can move dates in either direction. Follow the notice in SAM.gov so updates reach your inbox.
- Promote, don't duplicate. When an RFI turns into an RFP, update the existing row with the new notice ID and dates rather than starting over. You keep your notes and contacts.
- Submit a day early. Portal outages, file-size limits, and mailbox rejections happen on due dates. Build in 24 hours of margin on every RFP.
FAQ
Does answering an RFI obligate me to bid on the RFP?
No. An RFI response is market research only. Answering it does, however, give you early visibility and a chance to shape a set-aside decision.
Can a contracting officer shorten an RFP deadline after release?
Yes, through an amendment, though extensions are far more common. This is why daily amendment checks matter as much as the original due date.
Why did an RFQ never appear in my SAM.gov search?
Orders under GSA Schedules and many other vehicles are competed through eBuy or agency portals rather than SAM.gov. If you hold a vehicle, monitor its ordering channel separately.
