Can sales orders affect inventory?

Howdy gents!

The client I'm working with has a model where sale orders are placed but 
payment is not necessarily verified at the time that the sale takes 
place.  It could be as many as three days before payment is verified. 
Once payment is verified, an invoice is created.

For the client, this means that inventory needs to be committed at the 
time the sales order is created instead of waiting for the sales invoice 
to affect inventory.  Is this possible?
