You can use the ticketing service to manage memberships to your organization.
Indeed, in the same way that you can create different ticket prices, you can use the ticket office to create different membership rates for your organization.
First, create a new event in the ticket office and add "Membership" to its title.
When creating your event, in the "Tickets" section, use the "Add a ticket" button to create the desired number of membership rates.
In the "Event admission" section at the bottom of the event creation page, make sure to check "No ticket".
Otherwise, new members will receive a ticket with a QR code to scan.
