Replace a restaurant's spreadsheets with one operations app built with Claude

How they set it up

1. List every spreadsheet the business runs on: inventory, food cost, prep, scheduling, catering, venue contracts.
2. Build one app with Claude Code that works on a phone, and go live in days, then keep improving it.
3. Give each of the 12 team members access to only the screens they need.
4. Automate the routine reports: a daily prep briefing, an end-of-day sales and food cost summary, and a weekly digest.
5. Run catering from first inquiry to invoice in the same app.

Result

Admin time dropped from about 30 hours a week to about 2. Food cost went from 50% to a best week of 26%, with a normal target of 33-35%. (as reported by the source)
