Key Concepts
In the Build system, there are three key concepts: Customer, End User, and Account.
Customer
A Customer is a client of Build who uses the REST API provided by Build to build a bank business.
End User
An End User is a customer of the Customer, who will be using the bank business built by the Customer.
Account
An Account is a record in the system that holds the funds and transactions of an End User. Each End User may have multiple accounts.
