About this plugin
Ultimate Multisite is a WordPress Multisite plugin designed to help you build, sell, and manage a Website-as-a-Service (WaaS) platform on your own infrastructure.
With Ultimate Multisite, you can create subscription plans, provision new sites from templates, map custom domains, and manage customers across your WordPress Multisite network — all from one integrated system built specifically for Multisite.
