# Cowork Vendor Comparison

Compare vendor proposals the way a procurement lead does: normalize everything to the same units before judging anything, price the full term not the first invoice, and read the terms the sales deck skipped. Input: a folder of quotes/proposals/SOWs (PDF, .docx, .xlsx) and, ideally, one sentence on what the purchase needs to accomplish.

## Workflow

1. **Extract per vendor:** pricing structure (license, usage, implementation, support tiers), contract term and renewal terms, SLAs and remedies, implementation timeline and dependencies, what is in scope vs. priced as add-on, exit terms (data export, termination fees), and every assumption the proposal states.
2. **Normalize.** Convert all pricing to a common basis -- same seat count, same usage volume, same term. Where a proposal is silent on something another proposal prices (training, integrations, overage rates), mark it `UNPRICED -- ask`, never zero. Unpriced is not free.
3. **Compute TCO** over the realistic term (default 3 years): year-one cost, steady-state annual cost, escalators applied, one-time costs amortized, and the exit cost. Show the math per vendor.
4. **Matrix.** Output `vendor-comparison.md`: side-by-side table of cost, capability fit against the stated need, SLA strength, implementation risk, and contract flexibility -- each cell citing the source document and page. Follow with a plain-English paragraph per vendor: the honest case for and against.
5. **Negotiation prep.** For the top 2 vendors: leverage points (their weaknesses vs. the rival's strengths, end-of-quarter timing, multi-year vs. flexibility trades), the specific asks worth making (cap the escalator, free implementation, opt-out at 12 months), and 5 reference-check questions targeting each vendor's specific risk areas.

## Rules

- Never judge from unnormalized numbers. A lower sticker with usage pricing can be the expensive option.
- Every cell in the matrix traces to a document and page. "Vendor B has better support" without a citation is vibes.
- Silence is a finding: what a proposal does not say (no uptime SLA, no data-export clause) goes in the matrix as prominently as what it says.
- Do not manufacture a winner. If the vendors genuinely split on cost vs. capability, present the trade and the decision criteria, and say which way the stated need leans.
- Flag lock-in explicitly: proprietary data formats, migration fees, auto-renewals with long notice windows.
- If proposals answer different scopes (one quoted 50 seats, one quoted 200), lead with that mismatch and request aligned quotes before deep comparison.

## Quick Commands

- "Compare [folder]" -- full workflow
- "TCO only" -- steps 1-3
- "What's unpriced?" -- the ask-list of gaps per vendor
- "Prep me to negotiate with [vendor]" -- step 5 for one vendor
