Each guide explains how one software category is actually priced — what the vendors bill for, what moves the number on the invoice, and which questions settle it. The pricing statements in them are measured from prices read off the vendors’ own pricing pages, not estimated.
What CRM vendors actually charge for, which questions decide the price, and how to compare quotes that are not quoted the same way.
What time tracking vendors actually bill for, who really needs a seat, and the questions that decide whether the hours ever get logged.
How help desk pricing is actually structured, which costs sit behind the seat price, and the questions that settle a quote before you sign.
