The write-up explains the purpose of the categories is so you can track sales tax more accurately. The post also explains, "Rules for how to tax a product or service can change depending on what you sell and where you sell it. QuickBooks keeps track of all those tax rules so you don’t have to."

 

As soon as I read the part  "QuickBooks keeps track of all those tax rules so you don’t have to."   I was SOLD! 

Thanks so much for sharing this. I'm sure I'll refer back to the link more than once. :)
