I have taken a job selling a customized "online workplace management application."
Our clients' businesses work around the application. Our clients track their time (which is how they get paid), finances and work documents through the application we provide and give their clients access to their interests throught the application. Our clients range from 2 users to 500 users. Each user probably processes 200 files per year and generates a fee for each file in the range of $500-$2500 per file.
The application has been refined over a period of years and has cost around a million to develop.
Does anyone know what range something like this sells for (source code, add-ons such as support and hosting)? I am trying to wrap my head around it as my background is not in software development.
