You can specify the trial days in three ways in Laravek Spark
- Per plan
Spark::plan('Basic', 'team-basic') ->price(10) ->trialDays(10) ->features([ 'Five Team Members', 'Feature 2', 'Feature 3', ]); - Globally
Spark::noCardUpFront()->trialDays(10);(or teamTrialDays() depending on what you have setup) - Both
You can apply ->trialDays(10) to the plan definition itself OR you can define it globally on the Spark class.
