With two selling plans (they’re called Individual and Professional, but you can think of them as standard and premium), Amazon offers you the flexibility to sell one item or sell thousands. Before you begin registration, decide which plan is a better fit for your business. The Individual plan costs $0.99 per sale, while sellers using the Professional plan pay $39.99 per month, no matter how many items they sell. If you sell more than 40 items a month, the Professional option makes a lot of sense. Whichever plan you select, don’t worry about making the wrong choice—you can change plans at any time.
