In this Tech Talk, we take an in-depth look at Commerce Billy. Commerce Billy provides a simple yet elegant set of tools to build an invoicing system atop of Drupal Commerce, giving developers and site builders a pathway to creating custom-tailored invoicing systems for their sites. This allows for a wide range of functionality for use-cases such as usage based billing, online bill pay, tiered user account payments, and more.

During this Tech Talk, we look at Billy's architecture, identifying moving pieces such as how invoices are generated, stored, and managed. Payment workflows will be discussed and explained. Billy's Views and PDF outputs will be reviewed and demoed as well. Mailing integration will be discussed as well.
