Step 2: From the top "Account & List Menu" choose the "Register for a Business Account" option.
Step 3: Amazon will ask you to provide a business email address to use for the new account.
Note: If you use the email address associated with an existing Amazon account, Amazon will prompt you to convert your existing Amazon account to an Amazon Business account.
If you opt to set up a fresh Amazon Business account distinct from your current Amazon personal account, simply follow the steps outlined earlier and make sure to use a different email address instead of the one already linked to your Amazon account.
