The basic initial response is complete. We use a templated mechanism which displays the success information on a web page and simultaneously emails it to the email address entered by the subscriber. That email address actually defaults to the one entered at registration.
There is more to do so this ticket remains open for more refined responses ...
- adjustments to the subscription higher or lower - but still above what has been consumed
- adjustments even lower than already consumed need to be discussed to ensure intentions are understood rather than blindly computed
- cancellation of subscription
Additionally, we might need to cater for users preferring to subscribe directly rather than through Stripe. That will require a separate ticket.
