On similar but slightly different topic, I was in a client's QBO yesterday and found that if you click on the sales tax link on an invoice, it brings up a secondary screen that shows what the tax rate should be based on the shipping address, vs. what was actually charged. Has anyone looked into this more with QBO to know if they added functionality to determine tax amount based on shipping address? QBO has two methods of charging sales tax--flat and auto. This was found while under the auto setting.
