In the Nue Self-Service API, a Customer represents an organization or individual that purchases your products or services. This concept is equivalent to an Account in Salesforce, and the terms are often used interchangeably when discussing Nue's integration with Salesforce.

A Customer record serves as the foundation for all commercial relationships in Nue, storing essential information such as:

• Basic identification (name, account number)

• Contact information (addresses, phone, email)

• Billing details (payment methods, terms)

• Classification data (industry, type, size)

The Customer object is designed to support both B2B and B2C business models, with flexible record types that can be configured to match your specific business needs.
