When adding an owner profile, you are able to set the working capital. The working capital is the minimum balance that must be on hold from a PMC to the owner.
The working capital exists in order to have a reserve in the event there are damages or other unscheduled expenses to account for.
For example, if there is $5,000 allocated as revenue to the owner for a particular month, but there is a $1,000 working capital, the owner will be paid $4,000 in total.
