If you setup a Recurring Payment type to manage the payment frequency this will automatically generate a subscription in Stripe.
If the customer wants to cancel, you can simply delete the Stripe Public and Secret key in the Voucher settings or disable the whole voucher campaign if its specifically for a client. In stripe, you can manually cancel the Subscription here, https://docs.stripe.com/billing/subscriptions/cancel?locale=en-GB

Below are the steps on how to enable Recurring Payment Type:
To configure this feature in Standalone Vouchers, users should navigate to the Voucher settings within Voucher Campaign Properties. Within the Payment settings, a new option titled "Payment type" has been introduced.
Opting for the "One Time" payment type will guarantee that the payments made by subscribers do not initiate a recurring payment cycle.
Choosing the "Recurring" payment type will unlock additional configuration options.
The "Recurring type" will manage the payment frequency
Instructional help text corresponding to the selected Payment gateway will be displayed.
Upon completion of the setup process, customer purchases will automatically generate a subscription in either Stripe or PayPal.
For Directory Voucher campaigns, the "Recurring Type" is still controlled in the Properties Payment settings.
While the "Payment Type" is managed individually within the Payment Settings of the Voucher Creator
