For what use case would an administrator enable Person Accounts during Order Management setup?

B2C Commerce uses Person Accounts to represent individual shoppers who place orders on the storefronts. Person Accounts are a type of account that combines account and contact information into a single record. To connect Order Management to B2C Commerce, an administrator needs to enable Person Accounts in Order Management and install the B2C Commerce Integration package from AppExchange.
