# Billing Overview

## 📘 Billing Overview

The Billing module in Canary7 allows you to automate and manage how customers are charged for services such as storage, handling, picking, and more. It works through a series of interlinked components. Charge Classes, Charge Types, Rate Cards, and Contracts. These components define **how charges are calculated, when they’re triggered, how much is charged, and to whom**. Once billing is set up, the Bill Screen provides visibility into all chargeable activity, enabling efficient review and confirmation of charges.

## 📚 Refined Definitions

### 🔧 [Charge Class](/v1/docs/charge-class)

> A system-defined billing formula that determines how a charge is calculated (e.g., per unit, per time period). Not configurable. Used by Charge Types to define the method of calculation.

### 🏷 [Charge Type](/v1/docs/charge-type)

> A configurable billing rule that defines when and why a customer is charged. Applies a Charge Class, sets criteria (like conditions or triggers), and defines what data is used for the calculation.

### 📄 [Rate Card](/v1/docs/rate-card)

> A collection of Charge Types with assigned rates. Defines how much the customer is charged for each type of activity or service.

### 📑 [Contract](/v1/docs/contract)

> A link between a Rate Card and a specific Company and Warehouse. Determines which rates apply to which customer in which warehouse location if required.

### 💳 [Billing Enquiry](/v1/docs/bill)

> The interface for reviewing and confirming automatically generated bills. Displays all chargeable activity as calculated through Contracts and Rate Cards.
