I am designing a graphic tshirt line very soon that I will be selling at market and friends retail stores. What is the best advice for the business license and such? I need a wholesalers license I would think to order shirts in bulk. That requires a business license & EIN. When researching the wholesalers license, it says I cannot participate in any type of retail. What does that mean? I can't open my own store? Please Help! thanks in advance!
