RFP vs RFQ vs RFI vs IFB: Which Government Solicitations Should You Actually Respond To?

Not all government solicitations are the same. 

RFP. RFQ. RFI. IFB. Different acronyms. Different purposes. Different strategies. 

Responding to an RFI like an RFP wastes time. Treating an RFQ like an RFP overcomplicates your response. 

Understanding each solicitation type helps you respond effectively. 

The Four Main Types 

1. RFI - Request for Information

2. RFQ - Request for Quote

3. IFB - Invitation for Bid

4. RFP - Request for Proposal 

Each serves different purpose and requires different response. 

RFI - Request for Information 

What it is: Market research tool. Not a contract solicitation. 

Purpose: 

• Understand what's available in market 

• Determine feasibility of requirements 

• Identify potential vendors 

• Gather pricing information for budgeting 

• Test market interest 

Key point: No contract will be awarded from RFI. 

When agencies use it: 

• Early planning stages 

• Before developing formal requirements 

• Considering new approaches 

• Gauging vendor interest 

• Budget development 

What they're asking: "Does this capability exist?" "Who can provide this?" "What would this cost?" "What approaches are possible?" 

Your response: 

Do: 

• Provide thoughtful information 

• Demonstrate capability 

• Offer insights and suggestions 

• Share relevant experience 

• Provide ballpark pricing (if requested) 

Don't: 

• Submit formal proposal 

• Invest weeks developing response 

• Expect contract award 

• Provide detailed pricing (save that for RFP) 

Length: 3-10 pages typically 

Why respond: 

• Establishes your presence 

• Demonstrates capability 

• Positions you for future RFP 

• Builds relationship 

RFI Strategic Value: 

Even though no contract results, RFIs are valuable: 

• You learn about upcoming opportunities 

  
  

• Agency learns you exist 

• You influence requirement development (sometimes) 

• You're prepared when RFP drops 

Many businesses ignore RFIs. Smart contractors respond. 

RFQ - Request for Quote 

What it is: Price-focused solicitation for standardized goods/services. 

Purpose: 

• Compare prices for known commodity 

• Quick procurement 

• Simple evaluation 

• Lowest price typically wins 

When agencies use it: 

• Standardized products or services 

• Clearly defined specifications 

• Price is primary decision factor 

• Simple, straightforward needs 

Examples: 

• Office supplies 

• Standard equipment 

• Routine maintenance services 

• Commodity items 

What they're asking: "What's your price for these specific items/services?" 

Evaluation: Usually lowest price among responsive quotes wins. Technical capability assumed (if you're qualified to quote). 

Your response: 

Do: 

• Provide exact price for specifications 

• Confirm you meet requirements 

• Keep response simple 

• Submit quickly (short deadline common) 

• Be competitive on price 

Don't: 

• Write lengthy technical approach 

• Propose alternative solutions (unless asked) 

• Complicate simple request 

• Inflate price assuming negotiation 

Length: 1-5 pages, mostly pricing 

RFQ Strategy: 

This is about price competitiveness. 

If you can't be price-competitive, don't respond. 

If your value is expertise (not price), wait for RFP where that matters. 

IFB - Invitation for Bid 

What it is: Formal sealed bidding for well-defined requirements. Common in construction. 

Purpose: 

• Award to lowest responsive, responsible bidder 

• Publicly opened bids 

• Formal procurement method 

• Fixed-price contracts 

When agencies use it: 

• Construction projects 

• Well-defined scope 

• Standard specifications 

• Public works 

Characteristics: 

• Detailed specifications provided 

• Lowest bid wins (if responsive and responsible) 

• Bids opened publicly 

• No negotiation after opening 

• Fixed-price contract 

What they're asking: "What's your price to build/deliver exactly what we specified?" 

Your response: 

Do: 

• Price accurately (you're locked in) 

• Ensure you meet every specification 

• Verify bonding capability (if required) 

• Include all required forms 

• Double-check math (errors costly) 

Don't: 

• Lowball then hope to make money on changes 

• Propose alternatives (not allowed) 

• Skip specifications review 

• Forget contingencies 

Length: Mostly pricing sheets, forms, bonds 

IFB Strategy: 

This is construction/commodity game. Price is king. 

Accuracy critical. Errors can be costly. Lowest bidder wins if qualified. 

If you're not construction-focused, you probably won't see many IFBs. 

RFP - Request for Proposal 

What it is: Comprehensive solicitation for complex services. Technical capability matters. 

Purpose: 

• Find best solution, not just lowest price 

• Evaluate multiple factors 

• Select based on overall value 

• Complex services requiring expertise 

When agencies use it: 

• Professional services 

• IT systems 

• Consulting 

• Complex projects 

• Services requiring expertise 

Characteristics: 

• Multiple evaluation factors 

• Technical approach weighted heavily 

• Best value selection 

• Price matters but isn't sole factor 

• Negotiation possible (sometimes) 

Evaluation factors (typical): 

• Technical Approach: 40 points 

• Past Performance: 30 points 

• Key Personnel: 20 points 

• Price: 10 points 

What they're asking: "How would you solve our problem? Why should we choose you? What's your price?" 

Your response: 

Do: 

• Comprehensive proposal 

• Address all evaluation criteria 

• Demonstrate understanding 

• Provide detailed approach 

• Show relevant past performance 

• Price competitively but fairly 

Don't: 

• Focus only on price 

• Use generic boilerplate 

• Skip past performance details 

• Miss evaluation criteria 

Length: 20-100+ pages depending on complexity 

RFP Strategy: 

This is where expertise wins. 

Invest time in quality proposal. This is your showcase. 

Technical capability and approach matter more than lowest price.

How to Decide What to Respond To 

Respond to RFI if:

✓ You want to be considered for future RFP

✓ You can provide valuable market insights

✓ Opportunity aligns with your strategic focus

✓ Time investment is minimal (few hours) 

Respond to RFQ if:

✓ You're price competitive for this commodity

✓ You can meet specifications exactly

✓ Quick turnaround is manageable

✓ Margin is acceptable at competitive price 

Respond to IFB if:

✓ Construction/commodity work in your wheelhouse

✓ You can price accurately

✓ You have bonding capability (if required)

✓ Your price is competitive 

Respond to RFP if:

✓ You're qualified and competitive

✓ Opportunity aligns strategically

✓ You can invest 20-60 hours in quality proposal

✓ Win probability is reasonable (>15%)

✓ Contract size justifies pursuit effort 

Strategic Approach by Type 

RFI Strategy: 

• Respond to most relevant ones 

• Keep responses concise but thoughtful 

• Use as business development 

• Position for future opportunities 

RFQ Strategy: 

• Be selective (only if price-competitive) 

• Respond quickly with accurate pricing 

• Don't over-invest time 

• Volume approach (respond to many) 

IFB Strategy: 

• Construction specialists respond 

• Price very carefully (you're locked in) 

• Ensure bonding capability 

• Verify all specifications 

RFP Strategy: 

• Be highly selective (quality over quantity) 

• Invest significant time in winners 

• Comprehensive, strategic proposals 

• Focus on 2-3 simultaneous maximum 

The Bottom Line 

Different solicitation types require different strategies. 

RFI: Market research (respond to build relationships)

RFQ: Price-driven (respond only if competitive)

IFB: Sealed bidding (construction focus)

RFP: Best value (quality proposals win) 

Know which you're responding to. Tailor your approach accordingly. Don't waste proposal-level effort on RFQs. Don't submit pricing-only for RFPs. 

Match your investment to the solicitation type.
