RFI vs. RFP vs. RFQ — Which Do You Need?
Use an RFI to explore the market, an RFP to evaluate detailed proposals, and an RFQ to compare pricing for a defined scope. For AI vendor selection involving significant investment ($50K+), the RFP is the right tool. Most mid-market firms can skip the RFI if they've already identified 3-5 qualified candidates.
Here's how the three documents differ:
| Document | Purpose | Timeline | When to Use |
|---|---|---|---|
| RFI (Request for Information) | Market intelligence gathering | 2-3 weeks | You're exploring — "Who's out there?" |
| RFP (Request for Proposal) | Detailed evaluation with scoring | 4-8 weeks | You're deciding — "Which one is right?" |
| RFQ (Request for Quote) | Pricing comparison for defined scope | 1-2 weeks | You know what you need — "What's the final price?" |
The typical AI procurement sequence is RFI → RFP → RFQ, according to iValua's procurement guide. But here's the thing — if you already have a shortlist, skip the RFI and go straight to the RFP. Save the weeks.
If you're building an AI decision framework for your organization, the RFP phase is where you move from strategy to selection.
The 12 Essential Sections of an AI Vendor RFP
An AI vendor RFP should include 12 sections: executive summary, company background, scope of work, technical requirements, data privacy and security requirements, integration requirements, pricing and TCO structure, evaluation criteria, proof of concept requirements, SLA requirements, legal terms, and submission timeline.
According to Arphie's RFP guide, an effective RFP should be 8-20 pages plus attachments, with functional requirements limited to 25 or fewer line items categorized as Must, Should, or Nice-to-have.
1. Executive Summary
- Project overview and business objectives
- Expected timeline for evaluation and decision
- Key decision-makers and how the final call gets made
2. Company/Project Background
- Your company context, size, and industry
- Current technology stack and integration requirements
- AI maturity level — are you starting from scratch or expanding existing capabilities?
3. Scope of Work
- Specific AI use cases you're solving for (not "we want AI")
- Expected outcomes with measurable success metrics
- Constraints and boundaries for the engagement
4. Technical Requirements
- Model capabilities and performance benchmarks
- API/SDK requirements and documentation expectations
- Model architecture transparency — how the system actually works
- Versioning and update schedules
5. Data Privacy & Security Requirements
- SOC 2 compliance is non-negotiable. BrightDefense research shows 83-85% of enterprise buyers now require it as a vendor prerequisite.
- GDPR/CCPA compliance documentation
- Data residency requirements and encryption standards
- Incident response procedures
6. Integration Requirements
- Existing systems the AI solution must connect to (CRM, ERP, internal tools)
- API compatibility and data format expectations
- Data migration plan and timeline
7. Pricing & TCO Structure
- Licensing model (per-seat, usage-based, enterprise)
- Usage-based pricing caps — this matters more than you'd think
- Implementation costs broken out separately
- Ongoing maintenance and support fees
- Request a 3-year TCO projection, not just Year 1
Sections 1-7 establish what you need and what it costs. Sections 8-12 protect you — defining how you'll evaluate, test, and exit if needed.
8. Evaluation Criteria & Scoring
- Weighted scoring categories (see Scoring and Evaluation Framework below)
- Scoring scale and what each level means
- Minimum threshold scores for must-have criteria
9. POC/Pilot Requirements
- Success criteria defined upfront
- Timeline and data access needs
- Evaluation metrics and decision criteria
10. SLA Requirements
- Uptime guarantees (99.9%+ for production systems)
- Response and resolution time commitments
- Performance thresholds and remedy clauses
11. Legal & Contract Terms
- IP rights for any custom development
- Termination clauses and transition support
- Data portability — can you leave without losing your data?
- Vendor lock-in protections
12. Submission Timeline & Instructions
- Response deadline and required format
- Point of contact for questions
- Q&A process and timeline for vendor questions
The four sections that separate an AI vendor RFP from a standard IT RFP are model transparency, training data governance, bias mitigation, and explainability requirements. Standard templates miss all four.
AI-Specific Evaluation Criteria That Standard RFPs Miss
Standard IT RFPs cover functionality, security, and pricing. AI vendor RFPs must also evaluate model transparency, training data governance, bias detection and mitigation, and explainability. Most procurement templates miss these entirely.
OWASP's AI security evaluation criteria provide a starting framework, but here's what your RFP should specifically ask:
| Criterion | What to Ask | Why It Matters |
|---|---|---|
| Model Transparency | "Describe your model's architecture and training data provenance." | You need to know what's under the hood — in-house models vs. third-party APIs have different risk profiles |
| Bias Mitigation | "What demographic fairness metrics do you track — meaning, does the system produce different results for different groups of people? What's your testing methodology?" | Biased outputs create legal and reputational risk |
| Data Governance | "How is customer data handled, stored, and retained? Is it used for model training?" | Your data shouldn't train their next product |
| Explainability | "Can you explain why the model produces specific outputs? What audit trail exists?" | Regulatory compliance increasingly requires this |
Ask vendors to explain their model's training data provenance, bias testing methodology, and explainability framework. If they can't answer clearly, that tells you everything you need to know.
This connects directly to your broader AI governance strategy. The criteria you establish in the RFP become the governance baseline for the entire vendor relationship.
Scoring and Evaluation Framework
Use a weighted scoring matrix with five categories to evaluate vendor proposals objectively. Apply a 1-5 scale per criterion, and publish your scoring criteria in the RFP itself. According to Arphie, RFPs with clear scoring criteria receive 3x more complete responses and 25% faster turnaround from vendors.
Recommended Scoring Weights
| Category | Weight | What It Measures |
|---|---|---|
| Technical Fit | 30-35% | Model capabilities, integration readiness, performance benchmarks |
| Vendor Fit | 20-25% | Track record, team expertise, cultural alignment, references |
| Total Cost of Ownership | 15-20% | 3-year TCO, pricing transparency, hidden cost risk |
| Security & Compliance | 15-20% | SOC 2, data governance, bias mitigation, regulatory readiness |
| Support & Services | 10-15% | SLA terms, implementation support, ongoing account management |
1-5 Scoring Scale
| Score | Meaning |
|---|---|
| 5 | Exceeds requirements — vendor offers clear advantages |
| 4 | Fully meets requirements |
| 3 | Meets minimum requirements with some gaps |
| 2 | Partially meets requirements — significant concerns |
| 1 | Does not meet requirements |
Set minimum thresholds. Any vendor scoring below 3 on security criteria, for instance, shouldn't advance regardless of other scores.
But here's the nuance. Scoring creates a shortlist, not a winner. Use it to identify your top 2-3 candidates, then apply qualitative judgment for the final decision. The numbers narrow the field. Your judgment makes the call.
Total Cost of Ownership Checklist
The initial vendor quote typically represents only 25-50% of your actual AI costs. Xenoss industry research found that 85% of organizations misestimate AI project costs by more than 10%. And 65% of IT leaders report unexpected charges from consumption-based AI pricing models.
That's not vendors being dishonest. It's the nature of AI deployments — costs compound in ways that traditional software doesn't. Plan for it.
| Hidden Cost Category | Typical Range | What to Request in Your RFP |
|---|---|---|
| Data Preparation | of total project costs | Detailed data prep scope, timeline, and pricing |
| Implementation Services | of first-year software costs | Implementation SOW with fixed-price option |
| Ongoing Compute/API | Variable — often the biggest surprise | Usage caps, overage pricing, historical usage data from similar deployments |
| Model Retraining | additional compute overhead | Retraining schedule, costs, and what triggers retraining |
| Compliance & Maintenance | of baseline budget | Annual compliance audit costs, integration maintenance fees |
| Personnel & Training | Varies by team size | Training program costs, ongoing support model |
The smart move: request a 3-year TCO projection from every vendor, broken out by these categories. If a vendor can't provide one, that tells you something about their maturity.

POC and Pilot Requirements
A proof of concept (POC) validates technical feasibility in 2-4 weeks. A pilot tests deployment readiness and ROI under real-world conditions. According to USDM Life Sciences, your AI vendor RFP should require at least one of these before contract commitment.
| POC | Pilot | |
|---|---|---|
| Scope | Narrow — single use case | Broader — real workflows |
| Timeline | 2-4 weeks | 4-8 weeks |
| Goal | "Can this work technically?" | "Does this work in our environment?" |
| Decision Output | Go/no-go on feasibility | Go/no-go on full deployment |
Define POC success criteria upfront using SMART goals — Specific, Measurable, Achievable, Relevant, Time-bound. If you can't measure it, you can't evaluate it.
The fundamental POC question: "If we build this, will it matter?" Don't skip this step. A $5,000 POC that prevents a $200,000 mistake is the best money you'll spend.

Common AI RFP Mistakes to Avoid
The most common AI RFP mistakes are vague requirements, missing AI-specific evaluation sections, choosing the lowest bidder, and skipping the POC phase. Any one of these can derail an implementation.
1. Vague requirements. "We want AI" isn't a requirement. Specify use cases, expected outcomes, and success metrics. The more specific your RFP, the more useful the vendor responses.
2. Missing AI-specific sections. If your RFP doesn't ask about model transparency, bias mitigation, and data governance, you'll get proposals that look like standard software bids. You won't know what you're actually buying.
3. Choosing the lowest bidder.
This is the most expensive decision you can make. The lowest initial quote often comes with the highest hidden costs. Evaluate on TCO, not sticker price.
4. Unrealistic timelines. AI implementations are iterative. Budget 4-8 weeks for the RFP phase alone, plus POC time. Rushing the evaluation leads to rushing the implementation.
5. Not publishing scoring criteria. Arphie's research shows RFPs with published scoring criteria receive 3x more complete responses. Transparency helps vendors give you what you actually need.
6. Skipping the POC. A proof of concept costs a fraction of a full deployment. And it's the cheapest insurance you'll buy.
7. Ignoring vendor lock-in. Require data portability, API access, and clear termination clauses. If you can't leave, you're not a customer — you're captive.
Move thoughtfully here. Bad AI implementations create more problems than no AI at all.
Frequently Asked Questions
How long should an AI vendor RFP be?
An effective AI vendor RFP should be 8-20 pages plus attachments, according to Arphie's RFP guide. Limit functional requirements to 25 or fewer line items categorized as Must, Should, or Nice-to-have. But don't confuse thoroughness with length.
How many vendors should receive an AI RFP?
Start with 5-7 qualified candidates for the RFP phase, per iValua's procurement guidance. If you're earlier in the process, use an RFI to screen 15-20 vendors down to your shortlist, then narrow to 2-3 for POC evaluation. More than that and you're creating unnecessary work for everyone, including yourself.
How long does the AI vendor RFP process take?
The RFP phase typically takes 4-8 weeks, plus 2-4 weeks for POC or pilot evaluation. A complete AI vendor selection process runs 8-12 weeks from RFP distribution to contract signing, according to iValua and USDM.
What scoring weights should I use for AI vendor evaluation?
A recommended framework: Technical Fit (30-35%), Vendor Fit (20-25%), Total Cost of Ownership (15-20%), Security and Compliance (15-20%), Support and Services (10-15%). Adjust weights based on your organization's priorities — a healthcare firm might weight security higher, while a startup might weight cost.
Next Steps
A structured AI vendor RFP protects your organization from vendor mismatches, hidden costs, and failed implementations. Start with the 12-section template above and customize it for your specific use case.
- Define your scope first. Know your specific AI use case before you write the RFP. Clarity here determines the quality of every vendor response you receive.
- Customize the template. Adjust section weights and requirements for your industry and AI maturity level. A company deploying its first AI solution has different needs than one expanding an existing stack. Treat your first RFP as a working draft — you'll learn what matters most to your organization by running the process.
- Assemble your evaluation team. Even a two-person review team — one technical, one business — produces better decisions than a solo evaluation.
Speed doesn't win here. The founders who succeed with AI aren't the ones who move fastest. They're the ones who evaluate most thoughtfully.
If mapping the right AI vendors to your specific workflows feels like a full-time job, that's exactly what a technology implementation partner can solve. At Dan Cumberland Labs, we help founder-led businesses navigate AI strategy and vendor selection — so you can focus on the decisions that actually need your judgment.
