You have a complete lack of understanding the underlying problem.

The problem isn't that it doesn't track sales tax, it does.

 It just collects the wrong sales tax in the "based on location" feature because the rate will not change with the change of location.

     It always charges sales tax based on my main business office address in account settings. We have 2 other locations that sell retail at those locations in other cities & states, no shipping, but when those locations are selected in the invoice the sales tax rate does not change to the correct for that location.

                 - Have called tech support 3 times and spent hours on the phone and no one seems to comprehend the problem or can even tell me if the program is supposed to be able to do this as the "Sales Tax Based On Location" option suggests.
