Why this exists
I was tired of jumping between Stripe, Notion, a spreadsheet for hours, and a Word doc for proposals every time a client emailed. Every tool wanted me to switch context, log in, copy data between them — meanwhile I was already in Claude Code 8 hours a day shipping client work. So I made the admin layer live where the work does. Conversational. Hosted server stores the data, AI handles the chaos.
