# Contract in. Invoice out.

You create a contract with customer, line items and billing cycle. On the due date, XOS creates a draft invoice. Nothing is sent on its own, you check the draft first.

## What this module handles for you.

01

### Create contracts

Give it a name, choose the customer from the ERP, from the CRM or as free text, and set the cycle (monthly, quarterly or yearly) and the next run.

02

### Line items from the catalog or free

Take items from the catalog or write a free-text line such as a maintenance flat fee, with quantity, net price, tax rate and discount.

03

### Draft invoice on the due date

A background service checks every hour which contracts are due. For each one, a draft invoice is created in the Document Generator, using its tax and numbering logic. Nothing is sent automatically.

04

### Fixed billing day

A contract dated the 31st bills on the 28th in February and on the 31st again after that. The day does not drift.

05

### Pause, resume, cancel

Contracts can be paused, resumed and canceled.

06

### Billing history

Every run is listed on the contract with date and status.
