Item purchases have a fourth status: Receive Item

In addition to Bill, Order and Quote, an Item purchase also has the Receive Item status. You'll use this status with inventoried items only. You'll use this status when you receive inventoried items, but no bill accompanied the items -- you're not sure of the final purchase price.

When you record a purchase using the Receive Item status, the item is added to your inventory, but the cost of the item is added to your Linked Account For Item Receipts (A/P Accrual - Inventory) until you record a bill for it. You're Accounts Payable account isn't affected at this time.

When you're ready to record the Bill, the purchase price will be transferred from your Linked Account For Item Receipts (A/P Accrual - Inventory) to the Accounts Payable account.
