RFP vs RFQ vs RFI: Which Procurement Document Do You Need?
Three procurement documents, three different purposes. This comparison helps you choose the right one for your situation and shows when to use them in sequence.
Side-by-Side Comparison
| Dimension | RFP (Request for Proposal) | RFQ (Request for Quotation) | RFI (Request for Information) |
|---|---|---|---|
| Purpose | Solicit detailed proposals with methodology, approach, and pricing | Get price quotes for a defined specification | Gather market information and vendor capabilities |
| When to Use | Complex projects with multiple valid approaches | Specifications are fixed, price is the differentiator | Exploring options before committing to a purchase |
| Level of Detail | High: 10+ sections, evaluation criteria, scoring weights | Low to Medium: specifications and price format only | Low: questionnaire about capabilities and general pricing |
| Response Format | Structured proposal (10 to 20 pages) | Price quote with line items | Informational response (3 to 5 pages) |
| Typical Timeline | 4 to 8 weeks total process | 1 to 3 weeks total process | 2 to 4 weeks total process |
| Budget Included? | Yes, as a range in the document | No, vendors provide the price | No commitment to purchase |
| Evaluation Method | Weighted scoring rubric (1 to 5 scale) | Price comparison (lowest or best value) | Qualitative assessment, no scoring |
| Commitment Level | Intent to purchase from winner | Intent to purchase from winner | No commitment to purchase |
| Typical Budget Threshold | $50,000+ | Any amount | Any amount (no purchase) |
Decision Flowchart
Do you know exactly what you need?
Is the specification completely fixed?
Use RFQ
Price is the differentiator
Use RFP
Evaluate approach + price
Use RFI
Gather information first, then decide on RFP or RFQ
When to Use Each Document
RFP: Request for Proposal
Use an RFP when the project is complex, multiple approaches are viable, and you need to evaluate vendors on dimensions beyond price. Typical scenarios: software implementations ($100K+), consulting engagements ($50K+), marketing agency selection, and design-build construction projects.
RFQ: Request for Quotation
Use an RFQ when you know exactly what you need and the specification is fixed. The only variable is price. Typical scenarios: office supplies, standard hardware, raw materials, commodity services with fixed specifications, and re-procurements of previously defined services.
RFI: Request for Information
Use an RFI when you are exploring the market before committing to a specific purchase. An RFI gathers information about vendor capabilities, available solutions, and general pricing ranges without the formality or commitment of an RFP. Typical scenarios: new category of purchase, technology landscape assessment, and vendor pre-qualification for a future RFP.
When to Use Them in Sequence
For large or complex procurements ($500K+), using documents in sequence produces better outcomes than jumping straight to an RFP:
Market Research
Send to 10 to 15 vendors. Gather capabilities, pricing ranges, and solution options. Narrow to 5 to 7 qualified vendors.
2 to 4 weeksDetailed Proposals
Send to 5 to 7 pre-qualified vendors. Evaluate approach, experience, team, and cost. Shortlist to 2 to 3.
4 to 8 weeksFinal Pricing
Request best and final offers from shortlisted vendors after presentations. Negotiate with the top-ranked vendor.
1 to 2 weeksWhen to skip steps: If you already know the vendor landscape (repeat procurement), skip the RFI and go directly to RFP. If the specification is completely fixed, skip RFP entirely and use RFQ. The sequence exists to reduce risk on large, unfamiliar procurements.
Other Procurement Documents
RFT (Request for Tender)
Common in UK, Australia, and government procurement. Functionally similar to an RFP but with more formal legal requirements and typically a sealed-bid process.
EOI (Expression of Interest)
A pre-qualification step where vendors indicate interest and basic capabilities before the buyer decides who receives the full RFP. Similar to an RFI but more formal.
BAFO (Best and Final Offer)
Issued to shortlisted vendors after initial evaluation. Asks them to submit their final, most competitive proposal. Used as the last step before vendor selection.
ITB (Invitation to Bid)
Used in construction when complete plans and specifications are available. Selection is typically based on lowest qualified bid rather than best-value evaluation.
