Run your entire design firm from one Notion workspace - Interior Design Firm OS

Most Notion templates for service businesses are shallow. Pretty pages with disconnected trackers. You download, get excited, and within a month nothing actually talks to each other. Abandoned tab. I wanted to fix that. Interior Design Firm OS is 12 databases with real relational logic - not 12 disconnected lists with "OS" tacked on the title. Projects sit at the center. Clients, Vendors, Rooms, Products, Orders, Payments, Communications, Action Plans, Revisions, Documents, and Showrooms all connect through proper relations and rollups. Color-coded project health that rolls up from the data automatically - not a manual status field you forget to update. Procurement tracked from spec → order → delivery → payment, every item linked to its project. 40 email templates so you stop rewriting the same client email for the 50th time. This is the deepest build yet from NotoMantra - a small Notion template studio I run solo. Free Notion account is all you need. No SaaS, no sync, no cloud lock-in. Brutal feedback welcome - especially if you run a design firm or agency. What's missing? What's wrong? Roast me.
