What field must be completed when creating a new customer in QuickBooks?

When creating a new customer in QuickBooks, the Customer Name field must be completed as it is a required field. This is essential for several reasons: the Customer Name serves as the primary identifier for each customer in the system, making it necessary for tracking transactions, sales, and communications associated with that customer. Without a unique Customer Name, QuickBooks would not be able to organize records properly or facilitate customer-related reports efficiently.

While the other fields—Customer Email, Customer Phone Number, and Customer Address—can enhance customer management and communication, they are not mandatory for saving a new customer record in the system. The ability to enter additional contact information is valuable but does not take precedence over establishing the core identity of the customer through their name. Therefore, the requirement of the Customer Name field is crucial in ensuring that every customer entry is complete and functional within QuickBooks.
