Payhip- anyone using?

I’m getting myself set up on Payhip to sell from my website. It was going well until I hit the page on charging taxes. I thought Payhip handled all of that…they don’t. They handle for the EU automatically, but for the US and other countries, you have to set it up BY STATE.

I’m overwhelmed to say the least. I don’t even know where to find this information and doing it x50 states seems ridiculous. (Plus the physical products are taxed differently than digital in some states to complicate things further)

How are people managing this complication? Where do you find the tax info? Any advice before i run the other way and give up?
