I just joined QB, 2-weeks ago.  I learned today; QB does not have a Sales Order!  This is the absolute stupidest thing, I have ever heard!  As several of the other respondents have outlined, there is an estimate (quote), then you receive the order (booked  business), an acknowledgement is sent to the customer and when the order ships, you invoice (billed business) the customer! 

This is standard procedure in most all businesses.  This is an absolute deal breaker for me!  Some of my order take weeks and months to ship.  How am I suppose to keep track of them, if I cannot enter them in my accounting system?

Since, I just joined; I am going to look to the other programs mentioned in this forum.
