RFP vs RFQ vs IFB: What's the Difference?

RFP vs RFQ is mainly a difference in how the agency evaluates your response: an RFP asks for a proposal, while an RFQ asks for a quotation. An IFB uses sealed bidding, with the agency generally awarding to the lowest-priced bidder that meets the stated requirements and is responsible.

The solicitation document tells you which process applies and exactly how to respond. Learn the format before pricing the work, preparing documents, or deciding whether to bid.

RFP vs RFQ: the main differences

A request for proposal (RFP) invites you to explain how you would meet the agency’s needs. Your response may include your technical approach, staffing, schedule, experience, and price. The agency evaluates proposals using factors listed in the solicitation, which can include both technical quality and price.

A request for quotation (RFQ) asks vendors to provide a price and other requested details, such as delivery, product specifications, or availability. In federal purchasing, a quotation is generally not the same as a formal offer. Follow the solicitation’s instructions about what to submit and how the agency will make its purchase.

An RFP is often used when the agency needs to compare proposed solutions or approaches. An RFQ is often used when the government can clearly specify what it wants and needs pricing from vendors. These are common patterns, not a guarantee: the solicitation’s terms and evaluation instructions control.

What is an IFB?

An invitation for bids (IFB) is a solicitation used for sealed bidding. The agency describes the work or supplies and tells bidders how and when to submit sealed bids. Bids are generally opened at the stated time, and the agency evaluates them against the requirements.

In a typical federal sealed-bid procurement, the agency awards to the responsible bidder with the lowest bid that meets the solicitation’s requirements. That means a low price alone may not be enough: your bid must be responsive, and your business must be found responsible. Read the evaluation and eligibility rules closely.

An IFB is different from an RFP because the agency generally does not compare competing technical approaches and negotiate to select a best-value proposal. If the requirements are unclear or you cannot meet a mandatory term, ask questions by the deadline rather than assuming the agency will make an exception.

RFQ meaning government buyers use

In government contracting, RFQ usually means request for quotation. The agency is asking you to quote a price and provide the information it needs to assess whether your offering meets its requirements. Depending on the procurement, the request may cover products, services, delivery, or other terms.

Do not rely on the acronym alone to decide how complicated a response will be. An RFQ can have detailed specifications, required forms, submission rules, and deadlines. Check whether the agency wants a quote, a technical response, or both, and note how it will evaluate submissions.

The Federal Acquisition Regulation and the agency’s solicitation provide the rules for a federal procurement. For a state or local opportunity, terminology and procedures can differ, so use the instructions in that jurisdiction’s bid documents.

RFP vs RFQ vs RFI

A request for information (RFI) is generally used for market research. The agency may ask businesses about available products, services, capabilities, or typical approaches before deciding what to buy or how to structure a later solicitation.

An RFI is not usually a request for a binding bid, and responding does not guarantee that the agency will issue a contract or invite you to compete. Still, a clear response can help the agency understand the market. Follow the RFI’s stated purpose and instructions, and do not include pricing or sensitive information unless requested and appropriate.

A simple way to distinguish the three is: an RFI gathers information, an RFQ requests a quotation, and an RFP requests a proposal for evaluation. An IFB instead uses sealed bids. The solicitation’s full text matters more than the title or acronym.

How to read the solicitation before bidding

Start with the submission deadline, delivery method, and point of contact for questions. Then identify the scope, specifications, contract period, place of performance, required forms, and evaluation criteria. Check for amendments because they can change the requirements or deadline.

Look for pass-or-fail conditions such as required licenses, insurance, certifications, representations, or minimum technical requirements. Confirm that your business can meet each one. If a requirement is unclear, submit a question through the method and by the date stated in the solicitation.

Make a compliance checklist that follows the agency’s requested order and format. A strong price or solution may not be considered if your response is late, missing required documents, or submitted in the wrong way.

• Record every due date, including question deadlines and any site visit or pre-bid meeting.
• Separate mandatory requirements from evaluation factors that are scored or compared.
• Check amendments and acknowledge them as instructed.
• Verify the submission format, file requirements, and delivery instructions.

Choose the right opportunity and response

First decide whether the work fits your business. Compare the scope with your services, staff, equipment, location, past performance, and ability to meet the schedule. Review the agency’s evaluation method and estimate the full cost of performance before committing to a price.

Check the NAICS code and any set-aside or eligibility requirements. NAICS codes identify industries, and the SBA sets a small-business size standard for each code. Use the free NAICS code lookup to identify likely codes, then verify the code and size standard in the solicitation and through the SBA.

For an RFP, organize your response around the evaluation criteria and explain how your team will deliver the work. For an RFQ or IFB, make every requested specification and commercial term easy to verify, and submit the required price information in the requested format.

Find bids and prepare to compete

Federal contract opportunities are posted on SAM.gov under Contract Opportunities. Search by keywords, location, agency, and industry, then read each notice and its attached solicitation. You can also browse open federal bids, review federal agencies and what they buy, and explore federal contract spending by industry to help focus your search.

Past awards on USAspending.gov can help you learn which agencies buy similar work and what kinds of contracts they have awarded. Award history is useful context, but it does not predict a future award or tell you whether a current solicitation is a good fit.

If you decide to pursue federal prime contracts, make sure your SAM registration is active. Registration at SAM.gov is free, and you must complete a full registration to bid on federal prime contracts. A UEI alone is not a full registration. Free support is available from APEX Accelerators, SBDCs, and SCORE; no paid registration service is required.

Frequently asked questions

What is the difference between an RFP and an RFQ?

An RFP asks for a proposal, often including your approach, qualifications, and price, and the agency evaluates it using stated factors. An RFQ asks for a quotation, commonly focused on price and whether your offering meets the requirements. The solicitation tells you what to submit and how the agency will evaluate it.

How do I find government contracts to bid on?

Search SAM.gov Contract Opportunities for federal solicitations, using relevant keywords, industries, agencies, and locations. Read the full notice and solicitation, including amendments and deadlines, before deciding to bid. Past federal awards are available on USAspending.gov, but they are not a substitute for reviewing current opportunities.

What is a capability statement?

A capability statement is a short business document that summarizes your services, qualifications, experience, and relevant business information for government buyers or prime contractors. It is commonly used for introductions and market research, but it does not replace a solicitation response. Follow the bid instructions if the agency requests specific forms or information.

What is an IFB, and how is it different from an RFP?

An IFB, or invitation for bids, uses sealed bidding and generally awards to the lowest-priced responsible bidder whose bid meets the requirements. An RFP asks for proposals that the agency evaluates using its stated factors, which may include technical approach and price. Always check the solicitation for the specific evaluation and submission rules.

What does RFQ mean in government contracting?

RFQ usually means request for quotation. The government asks vendors to provide a price and other requested details, such as delivery or compliance with specifications. Federal RFQ procedures can differ from a formal offer process, so follow the solicitation’s instructions rather than assuming a quote works like an RFP proposal.
