What is a Software RFP?
A Request for Proposal (RFP) is a formal document that describes your software project and invites vendors to submit proposals for how they would build it, how long it would take, and how much it would cost.
RFI
Request for Information
Gathering general info about vendors and their capabilities. Used early in the process.
RFQ
Request for Quote
Getting price quotes for a well-defined scope. Less detailed than RFP.
RFP

Comprehensive solicitation including approach, methodology, team, timeline, and price.
When Do You Need an RFP?
Not every project needs a formal RFP. Here's how to decide.
Rule of Thumb
RFP Structure & Template
A complete software RFP includes these sections. Copy this structure for your next project.
1. Executive Summary
1 pageGive vendors context about your company and project goals
2. Project Scope
3-5 pagesDefine what you're building
3. Technical Requirements
1-2 pagesSpecify any technical constraints
4. Timeline & Milestones
1 pageSet expectations for delivery
5. Budget Range
Half pageHelp vendors right-size their proposals
6. Vendor Requirements
1 pageSpecify who you want to hear from
7. Submission Requirements
1 pageTell vendors what to include in their response
8. Evaluation Criteria
1 pageShow vendors how you'll decide

Evaluating Proposals
You've received proposals. Now what? Here's how to evaluate them systematically.
Initial Screening
Eliminate proposals that don't meet basic requirements
Technical Evaluation
Assess the proposed approach and team
Commercial Evaluation
Compare pricing and terms
Reference Checks
Verify claims with past clients
Final Presentation
Invite top 2-3 vendors for live presentation
Scoring Framework
Use weighted scoring to make objective comparisons. Here's a framework that works.
| Category | Weight | What to Score |
|---|---|---|
| Technical Approach | 30% | Architecture quality, tech stack fit, understanding of requirements |
| Team & Experience | 25% | Relevant portfolio, team qualifications, availability |
| Price | 20% | Total cost, value for money, payment terms |
| Timeline | 15% | Realistic schedule, milestone clarity, risk mitigation |
| Communication | 10% | Proposal quality, responsiveness, clarity |
Scoring Example
| Category | Weight | Vendor A | Vendor B | Vendor C |
|---|---|---|---|---|
| Technical | 30% | 8/10 | 9/10 | 7/10 |
| Team | 25% | 7/10 | 8/10 | 9/10 |
| Price | 20% | 9/10 | 6/10 | 8/10 |
| Timeline | 15% | 7/10 | 8/10 | 7/10 |
| Communication | 10% | 8/10 | 9/10 | 6/10 |
| Weighted Total | 100% | 7.8 | 8.0 ✓ | 7.5 |
Vendor B scores highest despite not being cheapest. The framework ensures you don't over-index on price.
Common RFP Mistakes
These mistakes cost organizations millions. Learn from others' failures.
Vague requirements
Vendors interpret differently, proposals aren't comparable
Fix: Write detailed user stories with acceptance criteria
No budget range
Proposals range from $20k to $500k, wasting everyone's time
Fix: Give a realistic range (±30% is fine)
Too many requirements
Vendors quote for everything, price is unaffordable
Fix: Prioritize must-haves vs nice-to-haves clearly
Choosing lowest price
Cheap vendors cut corners, project fails
Fix: Use weighted scoring, cap price at 20-25% of score
Skipping references
Discover problems after contract is signed
Fix: Always call 2-3 references, ask specific questions
Unrealistic timeline
Good vendors don't bid, or bids include hidden risk premium
Fix: Ask vendors for realistic estimates before setting deadline
Negotiation & Selection
You've picked your top candidate. Now it's time to negotiate the final deal.
Don't just negotiate price
Timeline, payment terms, support, and scope flexibility often matter more than a 10% discount.
Get everything in writing
Verbal promises mean nothing. If it's not in the contract, it doesn't exist.
Define change order process
Requirements will change. Agree upfront on how changes are scoped, priced, and approved.
Include exit clauses
What happens if things go wrong? Define termination conditions, notice period, and IP ownership.
Milestone-based payments
Never pay more than 20-30% upfront. Tie payments to delivered, approved milestones.
The Modern Alternative: Skip the RFP
Traditional RFPs take 4-8 weeks and significant effort. Modern platforms offer a faster path.

Start Matching ProcessFrequently Asked Questions
What is a software development RFP?
A Request for Proposal (RFP) is a formal document describing your software project that invites vendors to submit proposals for how they would build it, including timeline, team, approach, and pricing. RFPs enable apples-to-apples comparison of multiple vendors.
How long does the RFP process take?
A traditional software RFP process takes 4-8 weeks: 1-2 weeks to write the RFP, 2-3 weeks for vendors to respond, and 1-2 weeks for evaluation and selection. Modern platforms like Archy can compress this to 1-2 weeks.
Should I include budget in my RFP?
Yes, include a budget range (not exact amount). This helps vendors right-size their proposals and prevents wasting time on proposals that are 10x your budget. A range like '$50,000-75,000' is appropriate.
How do I evaluate software development proposals?
Use weighted scoring across categories: Technical Approach (30%), Team & Experience (25%), Price (20%), Timeline (15%), and Communication (10%). Score each vendor 1-10 in each category, then calculate weighted totals for objective comparison.
What are the most common RFP mistakes?
Common mistakes include: vague requirements that vendors interpret differently, no budget range leading to wildly different proposals, choosing lowest price without considering quality, skipping reference checks, and setting unrealistic timelines that scare away good vendors.
