Most freelancers manage clients, projects and invoices across 3+ tools. SoloOS CRM replaces all of them with one relational Notion workspace. 4 linked databases: Clients, Projects, Invoices + a Dashboard showing who owes you money and what's due this week. Dark-themed, minimal, ready in 60 seconds. One click to duplicate. No code, no setup. Built for freelancers who want to run their business like a pro — without the $500/year SaaS bill.
