The tax center is an imposition turned into a nightmare.  By removing the option to allow the client create its OWN tax items, there is no way to create accurate invlices for clients withspecial tax rates.  Forexample,  in Puerto Rico allows some clients exemptions on city tax or to the state tax.  But QB Online is not breaking these taxes.  Even worse,  when an overwrite is selected,all it does is to incorrectly apply a % discount to each tax items.
