Subprojects are a great way to keep ASP business relationships organized.
One project can have many subprojects, each with a separately tracked ID. Once a project has subprojects under it, it becomes known as a parent project. The parent project will handle payment for all subprojects, yet each subproject will have its own unique set of data tied back to your customer.
You can create a new subproject for each customer. And should they leave, it’s as easy as deleting the subproject!
