About This Launch
Client OS is a Notion client operating system for solo freelancers and consultants. Pipeline, clients, delivery, and invoices live in one workspace. $39 once, not $19 a month for a CRM seat. Command Center shows unpaid invoices, next steps, and this week's deliverables. Clients do not log in. Duplicate it into a free Notion account and run the business from one place. Built by NORTHLINE.
Why I Built This
Solo freelancers keep pipeline in a sheet, clients in Notion, and invoices somewhere else. A monthly CRM seat is built for a sales team they do not have. NORTHLINE built Client OS so one person can track deals, delivery, and money in the Notion workspace they already use. One payment. No seats.
