I am confused as to when inventory gets updated in quickbooks online.   Lets say i have 10 widgets in inventory.   If i create an *estimate* for 2 widgets, will my inventory drop to 8 or remain at 10?   

How can i get an accurate update on inventory levels if it does not take into effect the items that are essentially 'reserved' for a customer in the estimate's that haven't been converted to invoices yet?
