Your team needs to know when to call you. If food costs spiral while you're not in the restaurant, hundreds of euros vanish daily. A solid decision tree stops your team from waiting too long to act—but also prevents them from calling about every minor issue.
When should your team call immediately?
Set firm boundaries where your team MUST act right away and call you:
⚠️ Call immediately if:
- Supplier raises price by more than 15%
- Main ingredient is out and there's no alternative
- Food cost of top dish rises above 40%
- Waste per day exceeds €100
- Refrigeration fails (temperature above 7°C)
What can your team solve themselves?
Train your team to handle these situations alone, without calling you:
- Price increase up to 10%: Accept and note for weekly meeting
- Alternative ingredient available: Switch and inform you later
- Minor waste (under €50/day): Log it
- Portion size deviation: Talk to chef and correct it
💡 Example decision tree:
Salmon rises from €18/kg to €22/kg (+22%)
- Step 1: Is this more than 15%? Yes
- Step 2: Call owner immediately
- Step 3: Decide together: raise price or find different fish
- Step 4: Implement decision and inform team
Create a warning system
Make sure your team knows which signals actually matter:
- Green: Everything normal, no action needed
- Orange: Pay attention, but team can handle it
- Red: Stop and call owner immediately
💡 Practical example:
Steak food cost check:
- Green: 25-35% food cost
- Orange: 35-40% food cost → warn chef
- Red: above 40% → call owner
At 40% food cost on a €32 steak, you lose €1.60 per portion in potential profit.
Train your team in cost awareness
Your team needs to understand why these boundaries actually matter. It's a pattern we see repeatedly in restaurant financials—teams that understand the 'why' make better decisions under pressure.
- Explain what 5% extra food cost means in euros per month
- Show how waste eats into profit
- Make clear they're thinking partners, not just executors
- Reward good signaling (team gets bonus for cost control)
⚠️ Watch out:
Don't make the rules too complicated. Your team should be able to decide in 10 seconds whether to call you or handle it themselves. When in doubt: always call.
Digital support for your team
A food cost calculator can help your team with:
- Automatic calculation of food cost per dish
- Alerts when food cost gets too high
- Central place to track price changes
- Overview of daily waste
This way your team doesn't have to do the math themselves, but they see immediately when action is needed.
How to build a decision tree for food cost control?
Set critical limits per cost item
Establish a limit for each important cost item: food cost above 35%, waste above €75/day, price increase above 15%. Make this concrete in euros and percentages your team can check.
Create a simple 3-color system
Green = everything normal, orange = pay attention but team handles it, red = stop and call owner. Make sure every situation falls into one of these categories so your team can decide quickly.
Train your team and test the system
Explain why each limit matters and practice with example situations. Test carefully the first few weeks to make sure your team makes the right decisions and adjust the limits if needed.
✨ Pro tip
Create a simple flowchart with yes/no questions and post it next to your POS system. If food cost exceeds 38% for 3 consecutive days, your team calls you—no exceptions.

Frequently asked questions
How often should my team check food costs?
Daily for your 5 best-selling dishes, weekly for the rest of the menu. Always compare prices directly with your last order when deliveries arrive.
What if my team calls too often about small things?
Raise the limits and train better. If they're calling at 32% food cost when the limit is 35%, they need more explanation about why that limit exists.
Should I use different limits per season?
Yes, vegetables are cheaper in spring so your food cost can be lower. Adjust your limits 4 times a year based on seasonal averages.
How do I prevent my team from making wrong decisions?
Keep the rules simple and clear. When in doubt, always call. Better to be called once too often than once too few and lose €500 on a wrong decision.
What if I'm not available for emergencies?
Assign a replacement (sous-chef or experienced staff member) who has the same decision-making authority. Make sure this person also understands the food cost logic.
Should different shifts have different thresholds?
No, keep the same limits for consistency. But make sure night shift knows which suppliers are available for emergency orders and their contact details.
How do I handle staff who ignore the decision tree?
Document when they don't follow the rules and address it immediately. One ignored €200 waste incident costs more than retraining the entire team.
