# ! Activating Apps and Integrations

BestInvoicing allows you to choose from over 20 integrations and apps (additional modules to expand the programme). They can be **activated for free**. An overview can be found in the menu 'Apps and Integrations' behind your email address (top right corner of the interface).

BestInvoicing offers applications specifically related to customers, products or more general settings. You can activate them by simply clicking the green 'Activate' button. For some apps, additional configurations are available.

The more apps and integrations you have activated, the more tabs will appear throughout your own BestInvoicing environment. Here you can see the difference between a basic account and an account with multiple activated apps and what it means for a customer file: 

### Basic account
