# Trial Period

It is common to support the consumption of digital services by introducing consumers to a variety of business models (such as trial periods and freemium offers). MarketONE supports these various models via Commerce Engine.

## Supported Capabilities

Product and pricing definitions are maintained in Commerce Engine and are flexible enough to have a variety of billing cycles (monthly, weekly, and annually), and also have the ability to define free or trial periods for customers. If a customer chooses to cancel a service during the trial period, they will not be charged for the service.

## Recommended Experience

While Commerce Engine supports any variety of payment methods and trial periods, it is recommended that to provide a consistent experience, all digital services have the same billing cycle (for example: monthly), and the same duration for the trail period (for example: 7 days). If different digital services are configured with different trail periods, it will yield to a higher amount of calls at the call center and inconsistent experiences.
