# Customer

### Definition

A customer in a PMS is a guest or booking agent record. It holds a name, contact details, and stay history.

<Note>
  In this context, "customer" refers to a guest or booking agent in the consumer's property management system, not the Chift [Consumer](/developer-guides/glossary#consumer) (the integrator's customer).
</Note>

### Purpose

Customers identify who stayed at or booked the property.

### Relationships

* A customer is linked to invoices and orders.
