The option to create a multi-item order
It would be really nice if you could build a multi-items list as an order to prepare for check-out check-in.
Look at it like a batch check-out / order.
You would be able to create a list of items before checking them out and assign them to the same person/client.
This would be a much more efficient workflow (for me at least).
You could then use that for invoicing since you would get totals and prices for each item.
An availability check could also be implemented on the order/list of items before checkout.
Let me/us know if this would be possible or not.
