Subtotals are important.  Period.  Poll your customers.

As for editing bill to and ship to, that should be able to be done on the invoice itself.  I'm not going to go edit a customer each time I do an invoice.  Again, poll your customers to see how important it is.

I have offered many suggestions from the software.  Trust me.  Because it's going from bad to worse... Not worth1/2 of what we're paying and all these changes are just making things impossible to run a business.
