Creating one
New purchase order appears on both the Inventory and Purchase orders tabs. Fill in the details, then use Add items, then Create purchase order.
Every one of those is optional. What a purchase order cannot be created without
is at least one item, each with a quantity and a Unit cost above $0.00.
Adding items from an order fills the unit cost in from the blank’s piece price
where it can, and leaves it blank where it cannot.

Adding items
The Add items dialog has two tabs. Needs purchasing lists exactly what your open orders are short of, and you can search it by item name, order number or customer, or narrow it to one store. This is the fast path: Itemstores has already worked out what you need to buy. Items there are grouped by product with a row per size and its count. Expand a size to see which orders are waiting on it, and tick a whole product to take every size at once. The button names the total you are adding. Quantities are already netted against what is on open purchase orders, so a shortfall another purchase order covers is not offered again. All items is your whole product list, for stock you want on the shelf regardless of current orders. It works differently: select a product, pick its variants, set the Quantity, then Add to purchase order. A product with sizes takes a quantity per size.The first item you add locks the dialog to that item’s supplier. Everything
after it is filtered to the same one, and the Supplier field fills itself in to
match if it was empty.

Receiving stock
Open the purchase order and enter what actually arrived in the Received column, per line. It saves as soon as you leave the field, on its own, without the form’s Save changes. A line’s received quantity can be anything from zero up to what you ordered, which is how a partly delivered order is recorded. Mark received on the Items panel receives every remaining item in one go. Received stock stops counting as Incoming in Inventory. It is allocated to the oldest orders still waiting on it first, so it lands under Committed before it shows as Available. Receiving is reversible. Lower the Received number and the stock comes back out, the incoming quantity reopens, and the purchase order’s status steps back.When some of what you are receiving belongs to orders that already shipped
without pulling stock, you are asked whether to Receive as already-used or
Add to stock. Already-used books the receipt and nets those units straight
back out, so they do not become inventory you do not have.

⋮ menu holds Add items, so you
can keep adding to one after it exists.
Cancelling one
Cancel sits in that same⋮ menu.
A cancelled purchase order can no longer be edited or received, and it drops out
of the All, Open and Late filters.
