What it is for. Track material orders placed with suppliers: what was ordered, from whom, for which job, and when it is due.
What you see. Four cards — total orders, how many are Ordered, how many Delivered, and total value. Then a table with the PO number, supplier, job, order date, expected delivery, total and status.
The Total Value card includes Draft and Cancelled orders. It is the value of everything on the page, not of what you have actually committed to.
Creating one. New PO needs a supplier before it will save. Then the job, dates, line items and amounts.
What happens when you mark one Delivered. An expense is created for the PO total, in the Materials category, against the same job. This is the automation that makes purchase orders worth using — and the one that double-counts if you also enter the cost by hand.
What it connects to. Jobs, Expenses, and job profitability through them.
