Purchase Orders#604

It would be really useful to be able to have Purchase Orders as well as Invoices. The documents look very similar, so it wouldn’t be much of a change to add.

Po should not have the payment detail. Even i ‘d enable the display button but still appear..i think bug issue. Please check it. Tq

I would like to create a PO for myself so that when I go see a job, I will make a PO for myself and then go buy the stuff. After that, PO should be connected to the quote and then if the job is done the quote should be converted to the Invoice. If need, add more stuff to the Invoice and send it to the client. That way it is easier to tell how much I have spent on parts and how much money I have made.
