Simple System (CodeCanyon Version): This is a script you purchase once and install on your own server (cPanel or VPS). It is single-tenant, meaning it's designed for you to manage all of *your own* products. You have full control over the code and data.
SaaS Version: This is our hosted service. You simply sign up for a subscription plan, and we handle all the server setup, maintenance, and updates. It's multi-tenant, allowing you to create accounts for your clients (as `support-agent` roles) who can then manage their own products under your main account.
