# Key terms: properties, lifts, and cars

> What LiftAI means by property, elevator/car, bank, and other core terms.

LiftAI uses a few core terms throughout the app. Knowing them makes the Portfolio,
Tickets, and other sections easier to read.

## Property

A **property** is any building or structure that houses one or more elevators —
for example an apartment complex, an office tower, a hotel, or a warehouse.
Properties are the top level of organization in your Portfolio; tickets, contracts,
invoices, and compliance records all roll up to a property.

## Elevator (car)

An **elevator** — also called a **car** — is a single unit that carries passengers
or goods between floors. LiftAI uses "elevator" and "car" interchangeably. Each
property has one or more elevators.

## Bank

A **bank** is a group of elevators that operate together within one property, often
serving a particular zone or set of floors. A large building may have several banks.

## Other terms you'll see

* **Ticket** — a record of a service visit, repair, or callback on an elevator.
* **Contract** — a service agreement between a property and an elevator service
  company that covers maintenance and repairs.
* **Invoice** — a bill from a service company for work done; reviewed under
  **Spending**.
* **Compliance** — certificates, inspections, and violations that keep elevators
  within safety and regulatory requirements.

<Note>
  These terms relate to each other directly: a **property** contains **elevators
  (cars)**, which may be organized into **banks**, and the service of those
  elevators is governed by **contracts** and recorded as **tickets** and
  **invoices**.
