We're new to NetSuite, and are working through our implementation, and have come across a scenario we're not sure how to handle.  We have a company we do business with, like a sub-contractor, and treat their employees almost like our employees, and assign them to Projects/Tasks with specified hours.  In our past project accounting system, they would enter their time, and then on a monthly basis they would pull a report of those hours, and then submit it to us as an Invoice which we would run through our financial accounting system.

So in NetSuite, what would be the appropriate way to handle this?  I feel like if we do things the same way, that there will be a big disconnect between those people "like employees" enter their time against our Projects, and then subsequently send us a bill that's not related to those same hours.  Is there a default way this should be handled, is it some kind of customization, or is there a simple way of doing it differently that allows us to handle the payment of "invoiceable hours" in an easier manner?
