Resources, planning and invoicng


I would like to do the following. For illustrative purposes, let’s say it’s a Construction company. I have say 10 Resources, five people and tractors. My customers buy packages of two people and one tractor, I call this Construction package.

Now, can I do it so that I invoice a “Construction package” and it Draws from the Resources I have?

What if I have Another package called “building package”. This is the basically the same but require Three people and one tractor. People and tractors can be used on either package.

Thanks for you input.
