Please for the love of humanity make Taxes in the mobile app POS Automatic. Why isn't this just baked in, instead of half-baked? Who has time to go into every product in the POS app and assign taxes? Why are POS taxes different than invoice taxes to start with?

If I need to charge different tax rates for different states in the app, how can we do this? Here is my immediate need >

Let's say my client is at a trade show in Las Vegas and needs to charge taxes on the spot, in real time to customers across 6 states based on their shipping address. They have 90 products, btw. How should they go about this? And yes, they qualify for Nexus in all 6.

Make it make sense.
