An RFQ (Request for Quote) is used when you have exact product specifications and need competitive pricing, typically with 2-3 week timelines and price-focused evaluation. An RFP (Request for Proposal) is used when you need vendors to propose solutions to complex problems, requiring 6-12 weeks and evaluating solution fit, vendor experience, and implementation approach alongside price. The key decision rule: if vendor expertise would meaningfully improve the outcome, use an RFP; if you just need competitive pricing for known scope, use an RFQ.

Understanding when to use an RFQ (Request for Quote) versus an RFP (Request for Proposal) is critical for effective procurement. The difference isn't just semantic; choosing the wrong document type can significantly extend procurement cycle time and result in mismatched vendor selection.
Here's what matters: An RFQ (Request for Quote) works when you need pricing for known specifications—think 5,000 units of a specific laptop model. An RFP (Request for Proposal) works when you need vendors to solve a problem—think "design our hybrid cloud security architecture." This guide breaks down the practical differences.
A Request for Quote is a procurement document used when you know exactly what you're buying and need competitive pricing. The product specifications, quantities, and delivery requirements are already defined—you're just comparing vendor pricing and terms.
Effective RFQs include:
Real-world example: A manufacturing company needing 200 identical industrial sensors, model XB-4400, with ISO 9001 certification, delivered to three facilities by Q3. The RFQ specifies the exact model, quantity per location, and delivery windows. Vendors respond with pricing, volume discounts, and delivery confirmation.
A Request for Proposal is fundamentally different. You're asking vendors to propose how they would solve your problem, not just what they would charge. The project requirements may be partially defined, but you need vendor expertise to shape the final solution.
Successful RFPs include:
Real-world example: A healthcare provider needs to modernize their patient data system while maintaining HIPAA compliance, integrating with existing EHR systems, and minimizing clinician training time. The RFP describes their current systems, data volumes (2M patient records), compliance requirements, and integration points—but asks vendors to propose the technical architecture, migration approach, and implementation timeline.
There's a growing trend: embedding RFQ-style pricing schedules within RFPs for complex projects. For example, an IT infrastructure RFP might ask vendors to propose the overall architecture (RFP-style) while providing unit pricing for specific components like servers and licenses (RFQ-style).
Your requirements meet these three criteria:
Specific scenarios:
Why this matters: Using an RFP when an RFQ would suffice adds unnecessary time to procurement cycles and generates vendor proposals that don't influence the decision.
Your project meets any two of these criteria:
Specific scenarios:
Some purchases fall in between. For example, website development for a small marketing site could be an RFQ if you specify exactly what you want (platform, page count, features) or an RFP if you want vendor recommendations on approach.
Decision rule: If vendor expertise would meaningfully improve the outcome, use an RFP. If you just need competitive pricing for a known scope, use an RFQ.
Speed and simplicity. With clear specs, vendors can respond in days, not weeks. Evaluation is straightforward: create a comparison spreadsheet of pricing, terms, and delivery dates.
Reduced vendor effort means better response rates. RFQs require significantly less effort than RFPs, which can improve response rates from invited vendors.
Objective decision-making. When price is the primary factor, bias is minimized. The lowest qualified bidder typically wins.
The hidden costs of oversimplification. Companies that issue RFQs for complex services (like "managed IT services") often get wildly incomparable responses because vendors made different assumptions about scope. One vendor's "monitoring" might mean automated alerts; another's might include 24/7 human analysis.
Price focus can exclude better solutions. If a vendor could deliver 90% of the value at 60% of the cost with a slightly different approach, an RFQ won't surface that option.
Vendor expertise improves the solution. In enterprise RFP responses, winning proposals often include solution approaches the buyer hadn't initially considered—approaches that improved outcomes.
Evaluation depth matches decision complexity. You can assess vendor experience, team qualifications, implementation methodology, and cultural fit alongside pricing and technical capability.
Competitive proposals drive innovation. When vendors know they're competing on solution quality, not just price, they invest in differentiated, creative approaches.
Time and resource intensity. A thorough RFP process requires significant internal hours for a mid-complexity project (drafting, vendor coordination, evaluation, presentations) versus less time for an RFQ.
Evaluation inconsistency. Without structured scoring rubrics, RFP evaluations can become subjective. AI-assisted evaluation tools can help standardize response analysis across evaluation team members.
Vendor fatigue. Complex RFPs requiring significant vendor effort to respond can discourage participation, especially from smaller vendors or those with lower win probability indicators.
Here's what separates successful from problematic RFQs:
Be specification-obsessive. The more precise your specs, the more comparable the responses. Include:
Standardize the response format. Provide a pricing template (spreadsheet) that all vendors complete identically. This reduces evaluation time significantly compared to free-form responses.
Clarify evaluation criteria. Even if price is 80% of the decision, tell vendors what comprises the other 20% (delivery reliability, payment terms, warranty, etc.).
Example: When issuing an RFQ for 500 enterprise laptop replacements, specify exact model (Dell Latitude 7420), configuration (i7 processor, 16GB RAM, 512GB SSD), Windows 11 Pro license, 3-year ProSupport warranty, delivery to 6 locations within specific date ranges, and Net 30 payment terms. This enables directly comparable quotes and quick decision-making.
Define the problem, not the solution. Describe your current state, pain points, and desired outcomes. Let vendors propose the "how."
Be transparent about budget. Companies that include realistic budget ranges receive fewer unworkable proposals. If your budget is $200-300K, say so—don't waste vendor time on $800K proposals.
Create weighted evaluation criteria and share them. Example breakdown:
Require structured responses. Provide a response template with specific sections. This makes evaluation easier and improves comparability.
Set realistic timelines. For a complex RFP requiring significant vendor effort, allow adequate time for responses. Rush timelines reduce response quality and may exclude qualified vendors.
Modern procurement benefits significantly from purpose-built tools:
For responding to RFPs: AI-powered platforms like Arphie analyze RFP questions, surface relevant content from previous responses, and generate draft answers using institutional knowledge. Teams using AI-native RFP automation see significant time savings.
For issuing and evaluating: Collaboration platforms with structured evaluation workflows, scoring rubrics, and automated vendor communication reduce coordination overhead.
For content management: Maintaining a single source of truth for standard responses (company background, security practices, technical capabilities) eliminates the version control chaos that plagues RFP response teams.
Real impact: Customers switching from legacy RFP or knowledge software typically see speed and workflow improvements of 60% or more, while customers with no prior RFP software typically see improvements of 80% or more.
The RFQ vs RFP decision fundamentally comes down to this: Are you buying a known product or solving a complex problem?
Use an RFQ when you can write complete specifications and price is the primary decision driver. You'll close faster and with less effort.
Use an RFP when vendor expertise would improve the solution, implementation complexity is high, or factors beyond price significantly influence success. You'll invest more time but get better outcomes for complex projects.
The most common mistake? Using an RFQ mentality (focusing primarily on price) when the situation demands RFP-level evaluation of capabilities and approach. This typically results in vendor mismatches that surface 6-12 months into implementation—when switching costs are prohibitive.
For organizations managing significant RFP volumes—whether issuing or responding—purpose-built automation tools have become increasingly important. Teams winning complex deals consistently are those who've systematized their RFP response process with AI-assisted content generation, collaboration workflows, and institutional knowledge management.
The procurement documents you choose and how you execute them directly impact vendor selection quality, procurement cycle time, and ultimately project success. Choose wisely based on what you're actually buying.
An RFQ (Request for Quote) is used when you know exactly what you're buying and need competitive pricing for specific products or services with defined specifications. An RFP (Request for Proposal) is used when you need vendors to propose how they would solve a business problem, requiring vendor expertise to shape the solution approach, technical architecture, and implementation methodology.
Use an RFQ when your requirements are completely defined, price is the primary differentiator, and the purchase is transactional with minimal implementation complexity. Specific scenarios include purchasing exact quantities of specific product models, buying commodity materials with standard specifications, or replacing existing equipment with identical models. RFQs typically close in 2-3 weeks compared to 6-12 weeks for RFPs.
An RFQ process typically takes 2-3 weeks from issuance to decision, with vendor responses ranging from 2-5 pages focusing primarily on pricing. An RFP process typically takes 6-12 weeks, with vendor responses ranging from 20-100+ pages that include solution design, implementation methodology, and detailed technical approaches. The extended timeline for RFPs accounts for the complexity of solution evaluation across multiple criteria beyond just price.
An effective RFQ should include precise product specifications with model numbers and technical specs, exact quantities and delivery schedules, payment terms and conditions, submission deadlines, and clear evaluation criteria weighted heavily toward price (typically 70-80%). Providing a standardized pricing template that all vendors complete identically reduces evaluation time and ensures directly comparable responses.
RFQ evaluation focuses primarily on price (70-80% weight) with minimal consideration for delivery terms and vendor reliability. RFP evaluation distributes weight across multiple factors: technical approach and solution fit (30%), vendor experience (20%), implementation methodology (20%), pricing (20%), and cultural fit (10%). This reflects that RFPs prioritize best value for complex requirements while RFQs prioritize lowest qualified bid for known specifications.
The most common mistake is using an RFQ mentality—focusing primarily on price—when the situation demands RFP-level evaluation of vendor capabilities and solution approach. This typically results in vendor mismatches that surface 6-12 months into implementation when switching costs are prohibitive. If vendor expertise would meaningfully improve the outcome or significant implementation complexity exists, an RFP is the appropriate choice despite the longer timeline.
