Three different things.
A MEMBERSHIP SITE
Recurring payment for ongoing access to content or a community.
Suits: publications, communities, ongoing services.
A COURSE SITE
Structured learning, frequently paid once, with lessons, progress and sometimes certificates.
Suits: training, teaching a skill, professional development.
A BOOKING SITE
Customers reserve a time slot or a resource.
Suits: salons, clinics, consultants, venues, equipment hire.
WHAT THEY SHARE
Restricted access Customer accounts Payment Something happening after payment
WHAT DIFFERS
- Membership: ongoing access, recurring billing
- Courses: structured content, progress tracking
- Booking: availability, scheduling, calendars
WHICH IS HARDEST
Booking, usually. Availability logic is genuinely complex.
WHAT TO DECIDE FIRST
What the customer is actually buying.
That determines everything else.
