Freelancer OS is a Notion template built for freelancers managing real client work. 6 linked databases (Clients, Projects, Tasks, Time Tracking, Finances, Contacts) that actually connect. Log time on a project and it rolls up to the client. Create a task and it links to the project. One dashboard to see everything. Built because most Notion templates are either too basic or built for startups, not solopreneurs doing client work. Available on Gumroad at $39.
