vendor-evaluation

Compute 3-year TCO by adding subscription fees, implementation and migration costs (often 0.5-2x year-one fees), integration maintenance, training, admin time, and exit costs. Compare finalists on this full figure rather than sticker price, since the cheaper-sticker vendor frequently loses on honest math.

Focus on renewal price caps, auto-renew notice windows, usage unit definitions, exit and data export rights, and SLA remedies with real termination rights. A renewal cap typically outearns a larger year-one discount because the discount expires while the cap protects every future year.

Start renewal prep at least 120 days before the notice window closes. Leverage depends on having a live competitive alternative, and alternatives cannot be refreshed inside a 60 or 90-day notice window, so late prep means accepting list-price increases.

Do not use this commercial evaluation workflow for open-source adoption decisions based on technical merit; use a technology-evaluation skill instead. The two run together only when evaluating paid development tools where both technical fit and commercial terms matter.

Buy licenses matching your realistic 6-month usage rather than optimistic 3-year growth projections, and negotiate locked expansion pricing for future growth. Review usage versus entitlements quarterly to reclaim shelfware before true-up adjustments arrive as surprises.
