Margin-Leak Analyzer
Finds where a restaurant quietly loses money on every plate.
PROBLEM
Hospitality margins leak where owners can't see — mispricing, portion drift, supplier cost creep. By the time it shows in the P&L, months of money are gone.
WHAT I BUILT
A tool that ingests real supplier invoices + the menu and flags exactly where margin leaks, plate by plate — so you fix the dish, not guess.
HOW IT WORKS
Parses invoices into ingredient costs, maps them to recipes, and compares true plate cost against menu price to surface the worst offenders. Built against real invoices from an Auckland restaurant — not toy data.
WHERE IT'S AT
In progress — building against real invoices from a live Auckland walk-in restaurant.
STACK
Python · data pipeline (WIP)
In build.
