For traditional, virtual, dark kitchens, ghost kitchens and foodtech restaurants
Take control of your restaurant's costs and finances without Excel in just 21 days.
You sell, you work non-stop… and at month-end the profit never shows up. The problem is rarely sales — it is the cost structure you do not control. That is where your money leaks, every single day.
It is a self-paced, intensive 21-day restaurant cost program, 100% over WhatsApp, to deepen your understanding of your costs and finances and drive fast changes that impact your business model. Every day you get specialized content in the group to execute the suggested daily activity on your own restaurant — no Excel needed and ready to apply immediately.
The MASTERESTAURANT® methodology applied in 8,400+ restaurants across 43+ countries, now as a practical 21-day challenge so you stop losing money to miscalculated costs and turn your sales into real profit.
It is a daily-execution challenge: 21 days applying to your restaurant, with WhatsApp guidance, until your costs and margin are under control.
The Costs & Finance Challenge is for you if you run a restaurant business, feel you work a lot and earn little, and want every sale to become real profit. It is designed for those who make decisions about the restaurant's money and are ready to fix their numbers for good:
It works for traditional restaurants, virtual restaurants, dark kitchens, ghost kitchens, foodtech and any restaurant business —single or multi-location— that wants to organize its cost structure, control food cost and waste, and take control of its finances without relying on Excel.
To be honest, this challenge is not for everyone. It is not for you if you identify with this:
OPTIMIZE your finances, IMPROVE your costs and EARN MORE MONEY: that is the goal of the 21 days.
You will master your cost structure —food cost, waste, fixed and variable costs— without relying on Excel.
You will price with method to protect your margin and decide with numbers, not intuition.
You will know exactly how much each dish costs and where your money goes every day.
You will calculate and control your real food cost to protect every margin point.
You will cut waste and spoilage and grow your margins sustainably.
You will read your key numbers and decide with data, without complex spreadsheets.
Four cost & finance fronts across the 21 days so your restaurant stops losing money and earns more.
You organize your restaurant's full cost structure and find your real break-even point.
You calculate real food cost per dish and close waste, theft and spoilage leaks.
You set profitable prices with menu psychology and engineering to maximize margin.
You read your key indicators and control cash flow to decide with data.
Daily content over WhatsApp to apply to your own restaurant — costs and finances without Excel.
*Content may be adjusted to maximize impact.
Every day, in the costs & finance challenge WhatsApp group, for 21 days. You apply it to your restaurant, not just learn.
Every day you get specialized content and a tool in the private group to execute the suggested daily activity on your restaurant.
You do not need Excel or advanced accounting: you work with simple templates and tools, ready to apply immediately.
The PRO+ Spot includes a private 1-on-1 session with Diego Parra to review your cost structure.
The challenge closes with a live group virtual session to consolidate what you applied over the 21 days.
On days 6, 12 and 18 we run a Q&A checkpoint: we answer your cost and finance questions on video, inside the challenge's private WhatsApp group.
