How can I separate wholesale orders from retail for tax purposes?

[detritusbooks]

I want to do wholesale orders, specifically because in my state, sales tax isn't paid on wholesale orders. But I'm not sure how to do the orders so that when I spit out my reports every quarter, the wholesale orders don't get lumped in with the retail sales when I calculate my sales tax owed. Who knows how to do this?

Does nobody know how to classify orders as "WHOLESALE" so that they don't get categorized for sales tax?
