it is for a cloud based SaaS product that is low-touch sales.
here is a list of inputs. feel free to message me and we can talk more if a discussion would prove useful.
pricing at pay by month, by quarter and by year.
mix assumptions on sales (free vs. pay by month,quarter,year)
attrition % assumptions by product and month - these drive rebuy units projection
unit sales -- new and rebuy
salary, benefits and other employee related cost assumptions for each major component
customer service headcount assumptions like how many support calls we envision for each 1000 users in installed base.
headcount & costs for network operations, r&d, customer service, marketing, sales, management and admin.
I decided to allow several assumptions to vary by month so I could decrease pricing over time, or decrease the attrition % overtime as our product improves. this make the model more complex, but I think is necessary.
