Soseki

Manage clients, projects, invoices, and expenses from one workspace. Soseki is a free, open source business management platform built for freelancers, consultants, and small agencies that want to replace scattered spreadsheets and separate business tools with a single, organized workspace.

Run Your Freelance Business From One Workspace
