The Vendor Editor
Opening a vendor from the Vendor List shows everything recorded about them, across a set of tabs.
Info
The vendor's name, address, phone, email and default payment terms, with their locations and contacts listed underneath.
Parts
The parts this vendor supplies. Each row records the vendor's own part number and their quoted price, which is what a purchase order line uses when you buy that part from them.
Adding parts
Drag parts onto this tab from the Parts list. A vendor part has to name a part that already exists — it is a record of what this vendor charges for something in your catalog, not a new catalog entry — so there is no "new vendor part" button. This is the same gesture the customer parts tab uses.
Open a row to edit the vendor's part number, their price, and the vendor status. Setting the status to primary marks this vendor as the one to quote from when a part has several suppliers.
Purchase Orders, Receivers and Bills
Three tabs listing everything raised against this vendor. New purchase orders are created from the Purchase Orders tab — see Purchase Orders.
