Amazon FBM Steps as a sole prop in FL, USA?

Hello all,

I decided to start FBM as a side hustle to pay for car insurance and gas while in university; if I make more $ great.

I plan on starting as a sole proprietor while doing Amazon FBM in the state of FL. Can someone kindly advise me on if I should be using a DBA, and if I would need a resale license or seller’s permit? I’m not familiar with the “setting up the business” portion of this and welcome any and all useful tips or advice.

Also if it matters, I intend on doing arbitrage.

Thank you kindly!
