One of the most popular requests we get for Commerce is for a free trial period for subscriptions. We've heard from many clients that wish to allow their members a free, or reduced cost trial period before auto-renewing the full price.
I'm pleased to say that we've now added this functionality into Invision Community 4.5. Let us take a look at how it works.
Initial Terms
In 4.5 you can now specify an initial term that is different to the normal renewal term for any subscription plan or product. For example, you could make the initial term $0 for 1 week and the normal renewal term $10 per month which will allow you to create 1 week free trial. The initial term doesn't have to be $0, you can use any special price for the initial term you like.

Subscription Plans showing Free Trials
For developers creating their own applications with Commerce integration, this functionality is also available to you simply by passing a DateInterval object representing the initial term when creating the invoice.
Collecting Payment Details for Free Trials
Previously, if you were buying something that is free, the entire of the last step of the checkout would just be skipped and the invoice marked as paid.
In 4.5, if:
The user is purchasing something which has a free initial period, but also has a renewal term (i.e. is a free trial), and You have a payment method which can collect card details (Stripe, Braintree, etc) The user will be prompted to provide payment details that will not be charged until after the free trial. If the user already has a card on file they will not be prompted to provide the details again but will see a confirmation screen rather than the order just being marked paid immediately.

Checkout Process for a Free Trial
As you can see, allowing a free or reduced cost trial period has never been easier. We hope that you enjoy using this new feature of Invision Community 4.5.
