Software for multi-location aesthetic clinics
One clinic account, extra locations, a booking page per site. Not a hospital records system and not a franchise ERP.

Two sites, one book
Two postcodes should not share a laser that lives in one basement. Locations are first-class: hours, resources, and the public treatment list are per site.
Staff still belong to the clinic. You can see both diaries. Each site only offers what that site opted in.
Setup Complete configures booking on up to three locations. More sites are a commercial conversation, not a custom fork.
What multi-site owners actually need
Hours, rooms, machines, and public booking lists per site.
LocationsA hosted page per site, or an embed from Settings. An empty list books nothing.
Online booking per siteThe clinic number you actually use. SMS and email cover the rest.
One WhatsApp or severalRevenue and occupancy you can filter. Not a data warehouse.
ReportsSetup Complete is the default quote when more than one site has a real patient list.
