An Amazon Professional Seller account is an account option for individuals or businesses that plan to sell more than 40 items per month on Amazon. It's a subscription-based account, where you pay a monthly fee, regardless of whether you make a sale or not.
With a Professional Seller account, you can list your items in multiple categories, and you have the option to use Amazon's fulfillment services, such as Fulfillment by Amazon (FBA) for an additional fee.
The fees for a Professional Seller account include a referral fee, which is a percentage of the total sale price, and a variable closing fee for certain items. Additionally, there is a monthly subscription fee of $39.99 for a Professional Seller account.
Professional Sellers have access to a wider range of tools and resources than Individual Sellers, such as access to Business Reports, Multi-Channel Fulfillment, and Inventory Management tools. They also have access to Amazon's advertising and promotional tools, such as Amazon Marketing Services (AMS) and the ability to create and participate in deals and coupons.
Overall, the Professional Seller account is a good option for businesses or individuals who plan to sell a high volume of items on Amazon and who want to have access to more tools and resources to manage their sales.
