I need a way to manage prospective jobs as well as active ones. Does PWF do both?

ProWorkflow has plenty of ways to categorize projects, and because so many of these options are customizable, you can specify one of those categories is for pending jobs.

From there, you’ll be able to create task templates that outline the events taking place before the project, like scoping and quoting. As this project would also be attributed to a client, you’d have a full record of their enquiring about your services right through to your current job(s).
