Implementing one-year limited access with single payement in Webflow


I have a client who wants to offer the payment of their association’s membership fee online. This fee is a one-time payment of 30 euros and allows the creation of a member account on the website with access to restricted content for one year. To extend access to this restricted content, there’s an annual subscription fee of 10 euros.

My question is: How can I enable access to the restricted content for only one year following a single payment? Additionally, how can I automatically send an email to the member at the end of this one-year free access period with a reminder to pay 10 euros to continue benefiting from it?

Thank you!
