We have a membership site (Photography club) and our memberships has specific start/end dates (Oct - June). When we sell a Membership its for a year regardless of when a member joins. We’re looking for a way to specify the start and end of a Membership and also pro-rate or discount the membership if someone joins partway through the year. Would appreciate any ideas.
I think this feature is not possible yet but it’s planned and can be available at any time.
If you are able to code custom things you can create that system with wix-ecom APIs which will be integrated with Wix Pricing Plans app and it’s APIs. But this will require advanced coding skills.
