Paid Membership

Hi There.

I am building a site which includes real-estate listings from multiple sources. I want to charge an agent a recurring fee to use the site, which allows them to post multiple listings for free.

I want the general public to post just one free listing, which I think I can do with a combination of packages and use once discount options (though I know I can’t stop people creating multiple IDs).

Trawling thru google I came across the post here…. https://wpinvoicing.com/looking-for-beta-tester-for-paid-members/

What happened to that? Did it ever go live?

Is there a way to configure the system to manage:
1. you have paid a membership (or subscription) fee and while that is valid, your listings are free.
2. you have not paid a membership (or subscription) you can have 1 free listing.

Thanks
