Scroll down and check to agree to all of the terms.
Then on the next page choose whether you want your Apple Developer account to be an individual or a company/organization.
You should choose company/organization if your app is for a business (either existing or new). This will allow you to invite other people to have access to the developer account in the future. It will also mean that the company information is shown in the app store listing rather than your personal information. Note: Your company must already be a legal entity for you to choose this option.
If you chose company/organization, Apple will require you to enter your organization's DUNS number.
