Builds the ROI and business case for one deal - value drivers, full investment, ROI, payback, three cases conservative-first, and a one-page case the champion can forward. The buyer supplies every assumption, each number labeled buyer-supplied, benchmark, or rep-assumed, and none invented. Covers B2B and high-ticket B2C.
