Categories, dues, applications, endorsed.

A club's membership categories become classes in QRID: full, associate, life, junior, corporate, whatever the club's bylaws define. Each class carries its own dues plan, its own privileges, and its own path in. An application records a sponsor and a seconder the way the committee's minute book always has, and standing (good standing, in arrears, suspended) is a fact the system tracks, not a spreadsheet someone updates by hand.

Dues post to the house account automatically on the class's billing schedule. A member's standing and their house account balance are the same record the front desk, the treasurer, and the member's own app all read.
