# Modules

Modules are the ideal addition to Order templates. A module is capable of enriching the items of an Order template with customer-related data for a selected period.

You have the option to modify an existing module by clicking on it. You can create a new module using the green plus button above the table.

The following modules are currently available:

#### Demand

The Demand module determines the invoiced quantities of the item within the specified period (Start date + End date). You use this module to display in the Item list / Order template how many pieces of this item the customer has already purchased. The sales force can use this information as a basis for decision-making.

####
