Hello, 

I work for a small landscape company, we are looking for the functionality to create a purchase order from each deal we close. Here is an example.

John is looking for landscaping, we create a deal for him and estimate that it will cost $20, the estimate includes $5 of stone from vendor A and $15 of dirt from vendor B. When Johns signs a contract and says the estimate looks good, its time to order materials.

Is it possible to convert the original estimate into a purchase order to order from both vendor A & B and be related to johns landscaping deal?
