I was about to sign up with Revecom and then realized that there was no way to calculate/include sales tax. There is no sales tax on hosting in my state but there is sales tax on some other services I might offer.

I can't include the sales tax in the price because these goods and services are ONLY taxable if delivered in state. So the system needs to be able to distinguish in-state from out-of-state sales.

Anyone know of a RELIABLE provider whose system calculates conditional sales tax?
