Depending on your sales volume, the requirement for analytics and selling tools, the need for branding and personalization, and the product categories you want to sell in, you should decide which option is appropriate for your FBM business. The Professional Seller Account would be the best choice if you expect to sell more than 40 products per month, need advanced selling tools and data, want to build a brand, and want to sell in restricted categories. However, the Individual Seller Account can be an affordable choice if you have a modest sales volume and don’t need the other features and perks.
