Couple

Couple of questions, First and foremost we produce and sell dog treats in Jackson, Michigan. We are setting up our website to start selling retail across the country. As I understand our tax laws the only nexus we have is our location in Michigan. We are a destination sales tax state and so must charge the correct rate for the location we are shipping to. How do I set that up on my cart page or do I need to do something with Stripe?.. I am waiting for a demo from TaxJar to see if they can support this. Also I need to move my cart button down maybe 10 to 15 pixels to get out of my top header. I have granted support acces to help with this. Thanks in Advance, Mark Bissinger
