If you plan on taking this business seriously, you should immediately sign up for a professional Amazon account. An Amazon professional account is currently
$39.99 There are four main reasons for this:
1. If you have a professional account, Amazon does not charge you $1 fee per book you sell. If you sell more than 40 books per month on an individual account, you'd be paying Amazon more money than if you had the pro plan.
2. A professional account allows you to use third party softwares. If you plan on using software like ScoutIQ or Go2lister, which will save you a ton of time and make you more money as a bookseller, you need a professional plan.
3. Your products will sell faster with a professional account because you will be buy-box eligible. When Amazon gives you the buy box, you get more sales. Without a professional plan, you are less likely to get the buy box.
