What is a weighted vendor comparison? A weighted vendor comparison scores each vendor against criteria that matter to your organisation (cost, capability, support, risk) with each criterion assigned a weight reflecting its importance. Rather than picking the lowest bidder, the method surfaces the vendor with the strongest risk-adjusted total cost of ownership across a multi-year horizon. This tool builds one in the browser: enter two to four vendors, set your weighted criteria, and export a defensible memo with a three-year TCO breakdown, a per-vendor risk register, and a clear verdict on whether the choice is a clear winner or a close call.
