RESTAURANT BUSINESS: HOW TO AUDIT A RESTAURANT AS AN ACCOUNTANT OR INTERNAL AUDITOR
An internal auditor has just resumed at TasteVille Restaurant and Lounge, a busy restaurant in Lagos that sells local dishes, continental meals, pastries, drinks, cocktails, and offers outdoor catering and food delivery. The business has never been audited before, making him the pioneer auditor. He has been instructed to identify and block all financial, stock, and operational leakages.
Dear Stuch,
What do you advise?
Here is our answer:
First, congratulations to him. Since the goal is to uncover and block leakages, here is what to do:
1. UNDERSTAND HOW THE RESTAURANT OPERATES
Know the workflow from food purchase to service delivery.
Understand the following:
Services offered: dine-in, takeout, delivery, catering, bar service.
Revenue sources: food sales, drinks and cocktails, pastries, service charges, catering fees.
Materials handled: raw food, ingredients, drinks, gas, utensils, consumables.
Operational steps: food purchase, storage, preparation, serving, billing, cash collection.
Record keeping: store sheets, recipe costing, kitchen logs, sales register, POS reports.

Kitchen wastage not reported
Over-portioning food
