I have an idea if anyone can make it which shouldn't be very hard. I believe it would be just a MySQL query and a couple of small php files to show the output in the admin.
It would be nice if there was a report that could generate all sales that had sales taxes on them based on your tax zones. I have to pay taxes each month to the state of nevada for my company and I had to go through the sales one by one to find all nevada orders.
Your all thinking why dont you go through the actual print out of the orders, but I have hndreds of orders and some get missed placed in the shuffle by me or one of my employees so I have to verify the numbers.
So that is why I think the report should just pull up the person name gross sales and taxes for the order almost like the who online report
I will make an attempt at it but I am no PHPer...
