Assuming customer have some subscription and addon is added. It would be good to have option for trial period (for both new addon added and even for increasing amount).
Thanks for writing to us!
Just to ensure that I've understood your requirement correctly, when a customer purchase a new addon to his existing subscription, you'd want to offer a trial for this addon?
Thanks for the confirmation.
We do have a feature request in place for this already, and I'll tag your request to the list for our engineering team to consider. Though no concrete ETA yet, we'll notify you if it made available in the future.
I'm also interested in this feature.
With Chargebee you can now provide add-ons for trial to your customers. Currently, the trial period for addons is available only via the API. You can save the details of the addon's trial period in the metadata of the addon. At the end of the trial period, the addons will move to an Active state. When it does, a separate invoice is generated for the addon.
Here's more about how you could create a trial period for Addons.
