Is there no way to record the status of inventory without affecting accounting?

Here are 2 examples:

1) We are receiving goods but are not invoiced by the supplier yet. But if we receive the items to maintain a clear inventory status, the items are marked as billed, even though we are not paying for them yet.

2) Custom has a large order with a number of items. Some items are getting picked up today, but I cannot close a few selected lines, while keeping the rest open, without closing the whole order.
