cowork-vendor-comparison
Drop a folder of vendor quotes, proposals, and SOWs on Cowork -- normalizes them into one comparison matrix, computes true total cost of ownership, surfaces the terms each vendor buried, and arms you with negotiation leverage points and reference-check questions.
Why this skill is useful
Adds a comprehensive executable workflow for vendor comparison that automates normalization, TCO calculation, and negotiation preparation, which the AI cannot generate on its own.

What this skill does
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. …
