Order stock from a vendor with a purchase order, the first step of the procurement cycle.
A purchase order is a commitment, not a transaction — saving one doesn't move stock or money yet. It's the first of four documents in Redovix's procurement cycle (order → receive → bill → pay), and each of the next three tutorials picks up exactly where this one leaves off.
Once saved, a purchase order sits in a draft-like state — it records what you intend to buy, from whom, and at what cost, but nothing in your books changes yet. That's deliberate: a PO is something you might send to a vendor for confirmation before anything is real. The next tutorial, receiving goods, covers the approval step that turns intent into an actual stock movement.
The unit cost on each line typically pre-fills from the item's purchase cost (set when you created the item), but it's editable per order — useful when a vendor's price has genuinely changed since you last bought from them.
