Supplier prices change constantly, but your menu often stays the same for months. This causes you to lose profit unnoticed on dishes whose ingredients have become more expensive. With KitchenNmbrs you see directly which dishes become too expensive and can quickly adjust your prices.
Why menu price updates are crucial
Your supplier raises beef by 15%. You don't update your menu. Every steak you sell now costs you an extra €3.50. At 20 steaks per week you lose €3,640 per year on this one dish.
⚠️ Watch out:
Many business owners only notice after months that their food cost has increased. By then the damage is already thousands of euros.
How KitchenNmbrs helps with price adjustments
In KitchenNmbrs you work with a central ingredient database. When your supplier raises a price, you update it once. The app automatically recalculates the new cost price of all dishes containing that ingredient.
- Central ingredient database with current prices
- Automatic recalculation across all recipes
- Immediately see which dishes become too expensive
- Menu price calculator for new selling prices
💡 Example:
Your supplier raises salmon from €24/kg to €28/kg (+17%):
- Salmon fillet: cost price rises from €6.00 to €7.02
- Food cost rises from 30% to 35%
- New minimum menu price: €32.73 (was €27.98)
You need to raise €4.75 to maintain the same margin.
The workflow for supplier changes
As soon as you receive a new price list from your supplier, go through this systematic check:
- Update ingredient prices in KitchenNmbrs
- Check which dishes exceed 35% food cost
- Calculate new minimum selling prices
- Decide per dish: raise price or adjust recipe
Which dishes to adjust first
Not all dishes need immediate adjustment. Focus on:
- Best-sellers: Dishes you sell a lot have big impact
- High food cost: Dishes above 35% cost you money
- Expensive ingredients: Meat and fish rise most in price
💡 Example prioritization:
You sell 50 steaks and 5 lamb shanks per week:
- Steak: €2 loss per portion = €5,200/year
- Lamb shank: €3 loss per portion = €780/year
Adjust the steak first, then the lamb shank.
Alternatives to price increases
Sometimes it's better to adjust the recipe than raise the price:
- Reduce portion size: 200g steak instead of 220g
- Cheaper ingredient: Replace ribeye with bavette
- Adjust garnish: Replace expensive vegetables with seasonal ones
⚠️ Watch out:
Test recipe adjustments first. Guests notice quality differences faster than a small price increase.
Timing of menu updates
Plan your price adjustments strategically:
- Season change: Guests expect a new menu
- Beginning of the month: Less noticeable than mid-month
- After holidays: Guests are used to higher prices
Avoid price adjustments during busy periods or just before holidays. Guests are more sensitive to price differences then.
How do you update your menu after a supplier change? (step by step)
Update ingredient prices in KitchenNmbrs
Go to your ingredient database and adjust the new prices from your supplier. The app automatically recalculates the new cost price of all dishes containing these ingredients.
Check which dishes exceed 35% food cost
View the overview of all your dishes and sort by food cost percentage. Dishes above 35% are probably costing you money and need to be adjusted.
Calculate new minimum selling prices
Use the menu price calculator to see what each dish needs to cost at minimum for a healthy food cost of 30-33%. Compare this with your current menu price.
Prioritize based on sales volumes
Focus first on your best-selling dishes. A loss of €1 per portion on a dish you sell 100 times per week costs you €5,200 per year.
Decide per dish: adjust price or recipe
Small price increases (€1-2) guests barely notice. For larger increases you're better off adjusting the recipe: smaller portion or cheaper ingredient.
✨ Pro tip
Update your ingredient prices immediately after each supplier invoice, not just when creating a new menu. This way you see in real-time if you're still profitable.

Frequently asked questions
How often should I update my ingredient prices?
Check your main suppliers at least monthly. For meat and fish prices can change weekly. Update immediately when you receive a new price list.
What food cost percentage is acceptable after a price increase?
Keep your food cost between 28-35%. Above 35% you're losing money on the dish. Below 25% you can probably offer more quality or price more competitively.
Do I need to adjust all dishes at once?
No, focus first on your best-selling dishes and those with the highest food cost. These have the biggest impact on your profit.
How do I communicate price increases to my guests?
Be transparent about quality and season. Avoid the word 'more expensive' and focus on 'fresh seasonal products' or 'premium quality'.
Can I adjust recipes instead of raising prices?
Yes, often that's better. Reduce portions by 10%, replace expensive ingredients or adjust garnishes. Test first to make sure quality stays the same.
What if my competitor doesn't raise prices after the same supplier change?
Your competitor is then losing money or using cheaper ingredients. Focus on your own margins - you can't be profitable with loss-making prices.
