The key to assigning a vendor when adding inventory is checking the “New Item” checkbox at the bottom left of the inventory screen. This does two things, it allows assigning a primary vendor and it allows setting a reorder level for the item. (Please note that if the “Max Quantity” is set to “0” the item will not be listed on the reorder report even when the quantity on hand reaches zero”)
To check to see what needs to be ordered, run Inventory Report #4, Inventory Re-orders – Primary Vendor. This report can be by all vendors or a specific vendor.
