  • Is it possible to offer a trial period when reactivating a canceled subscription?


Yes, this is certainly possible. 

Just hit the Reactivate Subscription option (on the right panel) on the subscription details page and use the Reactivate From field to set the past date. This will immediately move the subscription to ACTIVE. 

Here's a screenshot.



Furthermore, you can move the subscription to the trial state by giving the trial end date in Trial Ends At field. When this is given, the Reactivate From date acts as the trial start date and the subscription moves to ACTIVE state once the trial ends.

More information on this is here.
