"I can see how this feature would be beneficial to your business."  Not Your business, MOST businesses.  Saying you understand why this is a problem only makes it more ridiculous that it isn't implemented.  This should have been a base feature, you know it and we know it.  Why was it not included?  Why should we pay extra for sales order integration or risk issues with inventory using Estimates in QB Online.  What is the great feature that overrides this horrible decision on the developers part that would keep us from going with another Program?
