An RFQ (Request for Quote) asks suppliers for pricing on defined items, an RFP (Request for Proposal) asks suppliers to propose solutions for a broader need, and an RFI (Request for Information) gathers general information about supplier capabilities without committing to a purchase. Each document serves a different stage and purpose in the procurement process.
When to Use Each Document
Choosing the right procurement document depends on how well the buyer understands what they need and how far along they are in the sourcing process.
- RFI (Request for Information) — Use when exploring the market. An RFI is a fact-finding tool sent early in the sourcing cycle. It asks suppliers about their capabilities, product offerings, certifications, and general pricing ranges. There is no commitment to purchase, and responses are used to shortlist potential suppliers or refine requirements.
- RFP (Request for Proposal) — Use when the buyer knows the problem but not the exact solution. An RFP describes the business need and asks suppliers to propose how they would meet it, including their approach, methodology, timeline, and pricing. RFPs are common for services, software, and complex projects where multiple valid solutions exist.
- RFQ (Request for Quote) — Use when the buyer knows exactly what they need and wants competitive pricing. An RFQ lists specific items, quantities, and specifications, and asks suppliers to respond with firm pricing and delivery terms. RFQs are common for raw materials, components, and standardized products.
Key Differences at a Glance
| Factor | RFI | RFP | RFQ |
|---|---|---|---|
| Purpose | Gather information | Evaluate solutions | Get pricing |
| Detail level | General | Moderate to high | Very specific |
| Response format | Open-ended | Structured proposal | Line-item pricing |
| Commitment | None | May lead to contract | Leads to purchase order |
| Evaluation focus | Capabilities | Value and fit | Price and terms |
| Typical timeline | 2-4 weeks | 4-8 weeks | 1-3 weeks |
How They Work Together
These documents are often used sequentially. A buyer might start with an RFI to survey the market, narrow the field to 5-6 suppliers, issue an RFP to evaluate proposed solutions, and then send an RFQ to the top 2-3 finalists for final pricing. In practice, many procurement teams skip the RFI when they already know their supplier base and jump directly to an RFP or RFQ depending on the complexity of the purchase.
How Buyer24 Helps
Buyer24 supports the full sourcing cycle — from sending initial requests to collecting and comparing supplier responses. Whether the buyer sends an RFQ with specific line items or an RFP with broader requirements, the platform organizes all responses in one place and uses AI to extract and compare key data points across suppliers.

FAQ
Can I combine an RFP and RFQ into one document?
Yes, and many buyers do. For moderately complex purchases, a single document can describe the requirement (like an RFP) and include a pricing schedule for suppliers to complete (like an RFQ). This approach reduces cycle time but requires clear instructions so suppliers understand both what to propose and what to price.
Is an RFI legally binding?
No. An RFI is explicitly a request for information and creates no obligation for either party. It is important to state this clearly in the document to set supplier expectations.
Which document gets the fastest response?
RFQs typically get the fastest responses because they require the least effort from suppliers — the scope is defined, and the supplier only needs to provide pricing and delivery information. RFPs take longer because suppliers must develop a tailored proposal. RFIs fall in between.
