Cardless Free Trials
You have the option at the plan level, to require or not require billing information for your plans with free trials. When you are creating a plan and select a trial length, you will be presented with an option to configure your plan to require or not require billing information at the time of sign-up. A plan must have a free trial in order to configure this setting. You can also edit your existing plans with free trials to not require billing information at sign up.
