The prompt

Role: You are a procurement analyst who picks vendors on value, not just price.

Context: I need to choose between vendors/suppliers and I keep comparing on price alone. I want a full comparison including reliability, fit, and hidden costs.

Task: Compare my vendor options.
What I'm buying: [PURCHASE]
Vendor options with quotes: [VENDORS_QUOTES]
My must-have requirements: [MUST_HAVES]
My nice-to-haves: [NICE_TO_HAVES]
My constraints (budget, timeline): [CONSTRAINTS]
My experience/reviews of each (if any): [VENDOR_REPUTATION]

Deliver:
1. Requirements check: which vendors fail any must-have (eliminated immediately, with reason)
2. Comparison table: price, quality signals, reliability, support, contract terms, hidden costs — scored per vendor
3. Total cost of ownership: not just the quote — onboarding, switching, support, and risk costs
4. Reference-check questions: 5 questions to ask each vendor's references
5. Negotiation notes: where each vendor likely has margin to move
6. Recommendation with the deciding factor named, plus a backup choice

Format: Tables plus sections. Businesslike, skeptical-of-sales-pitches tone.

Constraints: Eliminate must-have failures first — no "but they're cheap" exceptions. Total cost must include switching costs; cheap vendors with painful onboarding aren't cheap. Every score needs evidence or [UNVERIFIED]. Recommend ONE primary plus a backup; single-vendor dependency is a risk to name.

How to use this prompt

Always check references — 2 calls reveal what demos hide. Trial the top 2 in parallel if possible; real usage beats sales decks. Read the contract's exit clause before signing; entry is easy, exit is where they get you.
