Per job, what has been ordered against each quoted product, what is still to order, and which purchase order it went on. A product turns green once its full quoted quantity is on ordered or closed orders.

Purchase, then Order Book. The list shows every job with a quote; the Filter splits them into fully ordered, part ordered and not started.
Each product shows quote quantity, ordered quantity and balance in the unit it is bought in. Amber rows have a balance; green rows are complete.
Tap a product and the orders pane lists every order that carries it, with status, quantity and date. An order number opens the order.
Raise the next order from the quote; the book updates the moment the order is placed. Draft orders are listed but do not count.
