RFP vs RFQ: Key Differences, Examples, and When to Use Each
Use an RFP when vendors need to propose a solution. Use an RFQ when the scope is already defined and you mostly need price. This guide explains RFP vs RFQ in plain English, then shows where RFI fits before either one.
Quick answer: RFP vs RFQ
An RFP (Request for Proposal) asks vendors to recommend a solution, explain their approach, and compete on value. An RFQ (Request for Quotation) asks vendors to price a clearly defined product or service. If you know exactly what you need, use an RFQ. If you need vendors to help shape the solution, use an RFP.
At a Glance
RFP
Request for Proposal
Comprehensive solutions for complex projects. Vendors propose unique approaches and are evaluated on multiple criteria.
RFQ
Request for Quotation
Pricing for specific, well-defined products or services. Focus on comparing prices for known specifications.
RFI
Request for Information
Preliminary market research to gather vendor capabilities and solutions before formal solicitation.
RFP vs RFQ vs RFI Comparison Table
The simplest way to choose is to ask whether the buyer wants a solution, a price, or information. RFP vs RFQ is the core buying decision: an RFP is for solution evaluation, while an RFQ is for quote comparison.
| Criteria | RFP | RFQ | RFI |
|---|---|---|---|
| Purpose | Ask vendors to propose a solution | Ask vendors to quote known requirements | Gather market information |
| Best question to ask | "How would you solve this?" | "How much will this cost?" | "What options exist?" |
| Complexity | High | Low to Medium | Low |
| Selection Criteria | Multiple factors (capability, experience, approach, price) | Primarily price | N/A (informational) |
| Vendor response | Proposal with approach, timeline, team, risk, and price | Quote with price, terms, delivery, and availability | Informational response about capabilities and options |
| Timeline | 60-120 days | 2-4 weeks | 1-3 weeks |
| Level of Detail | Very detailed | Specific specifications | High-level |
| Vendor Effort | High (days to weeks) | Low to Medium (hours to days) | Low (hours) |
| Binding Commitment | Yes (after contract) | Yes (after contract) | No |
| Typical Use | Software, consulting, security programs, construction | Office supplies, equipment, commodities | Pre-procurement research |
RFP vs RFQ Examples
Use an RFP for a sales or security platform
If a buyer needs an AI RFP response platform, they probably care about citations, integrations, data residency, reviewer workflow, implementation support, and pricing. That is an RFP because vendors should explain how the product solves the problem, not just return a unit price.
Use an RFQ for known hardware or services
If a buyer needs 50 laptops with exact specifications, a fixed support package, or a defined quantity of materials, an RFQ is usually enough. The vendor response can focus on price, delivery date, warranty, and payment terms.
Use an RFI before either one
If the buyer is not sure what the market can provide, start with an RFI. For example, a procurement team might ask vendors what AI, security questionnaire, or DDQ automation capabilities are common before writing a formal RFP.
Vendor-side tip: RFQs are short, RFPs need reusable answers
If your team responds to RFPs repeatedly, the hard part is not defining the term. It is finding approved content, answering buyer questions quickly, and showing reviewers the source behind each answer. That is where an RFP platform can help.
Request for Proposal (RFP) Explained
An RFP is a comprehensive document used for complex projects requiring customized solutions, creativity, and innovation. The organization describes desired outcomes and invites vendors to propose their unique approaches.
When to Use an RFP
- Complex projects with no standard off-the-shelf solution (e.g., custom software, enterprise implementations)
- Multiple evaluation criteria beyond price (technical capability, experience, approach, cultural fit)
- Open to different approaches and want vendors to propose innovative solutions
- Significant investment (typically $50,000+) requiring thorough vetting
- Long-term partnerships or strategic vendor relationships
RFP Examples
- • Enterprise CRM or ERP implementation (Salesforce, SAP, Workday)
- • IT infrastructure modernization and cloud migration
- • Management consulting services for digital transformation
- • Construction of a new office building or facility
- • Healthcare EMR system selection and implementation
Request for Quotation (RFQ) Explained
An RFQ is used when you know exactly what you need and want to compare pricing from multiple vendors. The specifications are well-defined, and the primary selection factor is price (though delivery time and payment terms may also be considered).
When to Use an RFQ
- Well-defined products or services with clear specifications (no customization needed)
- Price is the primary decision factor
- Commoditized goods or standard services available from multiple vendors
- Need quick turnaround (days, not weeks)
- Repeat purchases or ongoing procurement needs
RFQ Examples
- • Office furniture (100 desks, model #ABC-123)
- • IT hardware (50 Dell laptops with specific configurations)
- • Office supplies (bulk paper, pens, toner cartridges)
- • Janitorial services (defined scope, frequency, and requirements)
- • Commodity materials for manufacturing
Key Difference
RFQs are about "how much?" while RFPs are about "how would you solve this?"
Request for Information (RFI) Explained
An RFI is a preliminary document used to gather information about vendor capabilities, available solutions, and market options. It's not a commitment to purchase—it's market research to help you understand what's possible before issuing an RFP or RFQ.
When to Use an RFI
- Early planning stages—you're not ready to commit to a formal procurement process
- Need to understand market capabilities and available solutions before defining requirements
- Want to identify potential vendors for future RFPs
- Exploring emerging technologies or unfamiliar solution areas
- Building a vendor shortlist before formal solicitation
RFI Examples
- • "What AI-powered tools exist for automating customer support?" (exploring solutions)
- • "Which vendors provide ISO 27001 certified cloud hosting?" (vendor identification)
- • "What capabilities do you offer for data analytics?" (capability mapping)
- • "What are typical implementation timelines for ERP systems?" (market research)
- • "What security features are standard in modern collaboration tools?" (requirements refinement)
Pro Tip
Use RFIs to educate yourself about the market, then use that knowledge to write better RFPs with realistic requirements and evaluation criteria.
RFP vs RFQ: Which Should You Use?
Start Here: Do you know exactly what you need?
✓ YES → Next question
✗ NO → Use an RFI to research the market first
Is it a standardized product/service with clear specifications?
✓ YES → Use an RFQ to get pricing quotes
✗ NO → Next question
Is it a complex project requiring customized solutions?
✓ YES → Use an RFP to solicit comprehensive proposals
✗ NO → Re-evaluate your needs or consider an RFQ
Common Sequence
Many organizations follow this progression: RFI → RFP → Contract or RFI → RFQ → Contract
For complex software buying, the practical route is usually RFI for market learning, then RFP for vendor evaluation. For commodity purchasing, an RFQ can go straight to pricing once the specification is known.
Responding to RFPs, not just defining them?
If you are on the vendor side, the RFP vs RFQ distinction matters because RFPs create more answer work. RFQs usually need pricing and terms. RFPs often need security, implementation, product, support, compliance, and commercial answers that must be accurate and reviewable.

Frequently Asked Questions
Use an RFP when you need vendors to propose a solution, explain their approach, and compete on more than price. Use an RFQ when the scope and specifications are already clear and you mainly need comparable prices.
No. An RFQ asks vendors for a quote against known specifications. An RFP asks vendors to propose how they would solve a business problem, usually with methodology, timeline, team, experience, and pricing.
Use an RFP instead of an RFQ when the purchase is complex, the right solution is not fully defined, or you need to evaluate vendors on implementation approach, security, support, experience, and total value rather than price alone.
Yes. Most RFPs include a pricing section, but pricing is only one part of the evaluation. An RFQ is usually more price-led because the buyer has already defined exactly what they want to buy.
Use an RFI when you are still learning the market and need vendor capabilities, solution options, or requirement input before writing an RFP or RFQ. An RFI is research; an RFP or RFQ is a buying step.
A common sequence is RFI first, then RFP or RFQ. Use an RFI to learn what is possible, an RFP when vendors need to propose solutions, and an RFQ when specifications are fixed and you need pricing.
RFIs are usually fastest because they gather information. RFQs are also relatively fast because vendors price known requirements. RFPs take longer because vendors write full proposals and buyers evaluate quality, risk, implementation approach, and price.
