I own a catering business.  As such, I am required to file sales tax in every city that I deliver to.  I also have many tax exempt orders.  At the end of every month when I go to pay my sales tax, it would be nice if the tax rates were linked to the corresponding sales for the month. The same is true for the taxed and non-taxed sales.  Given that I am only using Invoices, would this make it easier for anybody else out there, or am I the lone wolf here?
