Buffer Bros CRM

The story

Buffer Bros is the mobile detailing company I co-founded, and this is the software that runs it. A Next.js CRM tracking every job, client, vehicle, quote, and expense, with dashboard metrics so we can see how the business is actually doing. Supabase handles auth, the database, and RPC functions; a Google Sheets sync keeps the books compatible with how we already worked. Built it because spreadsheets stopped scaling with the schedule.

What I learned

1. 01We did not start with software, we started with spreadsheets, and the CRM only got built at the point the schedule stopped fitting in one.
2. 02The Google Sheets sync exists because the books already lived there, and changing how my co-founder worked would have killed the tool faster than any missing feature.
3. 03Keeping the money math in Supabase RPC functions means a quote total is computed in one place instead of drifting across the frontend.
4. 04Dashboard metrics only earned their build time once they started changing which jobs we took.
5. 05Running the software for a business I own means every bug is one I feel on a Saturday, which is a very fast feedback loop.
