# Overview A **customer** is an entity on Octoo that is requesting and paying for services. Any user on the Octoo platform can establish a **customer** in order to request services. A **customer** does not have to be a *business* or an *organization*: an individual can be a **customer** too. Once a **customer** has a **partner** they can can begin requesting services. ## Basics * **OWNER —** A **customer** must have one (and only one) **owner**. This is the Octoo **user** who is ultimately responsible for managing the **customer** account. Ownership can be transferred; however, a **customer** must always have one **owner** at a time. * [**BILLING**](https://docs.octoo.com/customers/billing) — A **customer** must also define one **billing** person. This can be the same person as the **owner** or someone else entirely. The **billing** person is the default contact person for bills received and the person a **partner** will contact if they have questions about the bill. * **TEAM MEMBERS** — A **customer** can invite other people to join their customer account as a **team member.** Each **team member** can be assigned different **roles** that specify what the member can and can't do (permissions). You can add or remove members at any time. You can edit your team members by visiting: .
