RFQs are used for price comparison when requirements are 100% defined and standardized, focusing exclusively on cost, delivery, and payment terms. RFPs evaluate complete solutions for complex business problems where methodology, vendor capabilities, and approach matter as much as price, requiring vendors to propose how they'd solve challenges rather than just quote standardized products. The key decision factor is whether you need vendor input on the solution approach (RFP) or simply price quotes for predefined specifications (RFQ).

Choosing the wrong document type can lead to significant procurement delays. The difference between an RFP (Request for Proposal) and an RFQ (Request for Quote) isn't just semantics—it fundamentally changes how vendors respond, what information you receive, and whether you'll get the solution you actually need.
RFQs focus exclusively on price comparison for defined requirements. When you issue an RFQ, you're telling vendors: "Here's exactly what we need. Tell us your price and delivery terms." This works when you're buying 500 units of a specific laptop model or renewing a software license with known specifications.
RFPs evaluate solutions, not just prices. An RFP signals: "Here's our business challenge. Propose how you'd solve it, why your approach works, and what it costs."
RFQ structure:
RFP structure:
Well-structured RFPs with clear section headers and evaluation criteria typically generate more relevant vendor responses than loosely formatted documents.
RFQ responses are straightforward:
RFP responses require substantial effort:
RFQs generally take vendors significantly less time to complete than RFPs. Enterprise RFPs often require coordination across multiple team members, which explains why vendors are selective about which RFPs they respond to—and why your RFP quality directly impacts response rates.
1. Requirements are 100% defined and standardized
You're buying 200 identical standing desks with specific dimensions, weight capacity, and finish. The product specifications won't change based on vendor input.
2. You're comparing commodity pricing
Office supplies, bulk materials, standard software licenses, or recurring services where differentiation is minimal.
3. Price is the primary selection criteria
When you've already validated quality and compliance, and you're optimizing for cost. Procurement teams often use RFQs effectively for renewal scenarios where the incumbent vendor has a known baseline price.
4. Timeline is tight
RFQs can be issued and evaluated quickly. For urgent procurements, an RFQ gets you pricing fast.
Real example: A financial services company needed to purchase 500 laptops matching their existing fleet specs. They issued an RFQ to 5 vendors, received quotes within 3 days, and completed procurement in 9 days total.
1. The solution approach matters as much as the price
You need a new customer data platform, but you're open to different technical architectures (cloud-native, hybrid, API-first, etc.). The vendor's proposed approach will influence your decision.
2. You're solving a complex business problem
Implementing a new procurement system, redesigning your website, or launching a change management program. Complex projects benefit from evaluating vendor methodology, not just deliverables.
3. You need to assess vendor capabilities and experience
For projects with significant risk or strategic importance, you want to evaluate team qualifications, relevant case studies, and the vendor's understanding of your industry.
4. Requirements will evolve through vendor input
You have a business objective but aren't prescriptive about the solution. Vendor proposals might reveal approaches you hadn't considered.
Real example: A healthcare organization needed to improve patient intake workflows. They issued an RFP because they wanted vendors to propose different solutions—some suggested mobile apps, others recommended kiosk systems, and one proposed an SMS-based approach. The winning solution came from vendor innovation, not from the buyer's original specification.
Here's a procurement strategy that works well for mid-complexity projects:
Issue a lightweight RFQ to vendors asking for:
This helps you identify qualified vendors within your budget range quickly.
Send a comprehensive RFP to your shortlisted vendors requesting detailed proposals. This reduces vendor effort waste (they know they're in a smaller competition) and focuses your evaluation time on viable candidates.
Vague specifications: "High-quality office chairs" doesn't give vendors enough detail. Specify weight capacity, adjustability requirements, material standards, and warranty expectations.
Ignoring total cost of ownership: Choosing the lowest-priced vendor without considering shipping, installation, training, or maintenance costs can lead to higher long-term expenses.
Requesting customization in an RFQ: If you're asking for custom features or modifications, you need an RFP. RFQs assume standard offerings.
Unclear evaluation criteria: When vendors don't know how you'll score proposals, they guess at what matters. Explicitly weighted criteria improve response relevance.
Unrealistic timelines: Giving vendors insufficient time to complete comprehensive RFPs guarantees poor responses or fewer submissions.
One-size-fits-all RFPs: Sending identical RFPs to vastly different vendor types (boutique agencies vs. enterprise consultancies) results in misaligned responses. Tailor your RFP to your target vendor profile.
Overly prescriptive requirements: If you specify exactly how vendors must deliver the solution, you're eliminating their ability to propose innovative approaches—which defeats the purpose of an RFP.
AI-native RFP automation changes the procurement equation by:
For vendors responding to RFPs:
For buyers managing RFPs:
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.
AI automation is particularly impactful for RFPs because RFPs involve more unstructured content, subjective evaluation, and complex coordination compared to RFQs.
Ask yourself three questions:
Can I specify exactly what I need without vendor input? If yes → RFQ. If no → RFP.
Is price my primary decision factor? If yes → RFQ. If no → RFP.
Do I need to evaluate how vendors would approach the work? If yes → RFP. If no → RFQ.
For mid-complexity projects where you're uncertain, start with an RFI (Request for Information) to gather market intelligence, then decide whether to proceed with an RFQ or RFP based on what you learn.
The procurement document you choose sends a signal to vendors about what you value and how you'll make decisions. Choose intentionally, structure clearly, and you'll get better responses—whether you're optimizing for price or seeking the best strategic solution.

An RFQ (Request for Quote) focuses exclusively on price comparison for products or services with fully defined specifications, while an RFP (Request for Proposal) evaluates complete solutions including methodology, approach, and vendor capabilities for complex business problems. RFQs ask vendors 'what's your price for this exact thing?' while RFPs ask 'how would you solve this challenge and what would it cost?'
Use an RFQ when your requirements are 100% defined and standardized, you're comparing commodity pricing, price is the primary selection criteria, or you have a tight timeline. For example, purchasing 500 identical laptops with specific specifications is ideal for an RFQ since the product won't change based on vendor input and you're optimizing for cost and delivery terms.
Use an RFP when the solution approach matters as much as price, you're solving a complex business problem, you need to assess vendor capabilities and experience, or requirements will evolve through vendor input. RFPs work best for strategic projects like implementing new systems, redesigning workflows, or launching programs where vendor innovation and methodology are critical to success.
RFQs typically take 3-9 days from issuance to procurement completion because responses are straightforward pricing documents. RFPs require substantially longer timelines since vendors must coordinate across multiple team members to develop comprehensive proposals including technical approaches, methodologies, team qualifications, and detailed pricing models, often taking weeks to complete the full cycle.
Yes, a two-stage approach works well for mid-complexity projects. First, issue a lightweight RFQ requesting high-level approach, ballpark pricing, and relevant experience to filter vendors within your budget range. Then send a comprehensive RFP only to shortlisted vendors, which reduces vendor effort waste and focuses your evaluation time on viable candidates.
For RFQs, avoid vague specifications, ignoring total cost of ownership, and requesting customization in what should be a standardized quote. For RFPs, avoid unclear evaluation criteria, unrealistic timelines, one-size-fits-all approaches, and overly prescriptive requirements that eliminate vendor innovation. Unclear weighted criteria and insufficient response time are particularly damaging to RFP response quality.
