Poor seasonal inventory management drains €200-400 monthly from the average restaurant's profits. You're stuck with expensive winter products in summer that must be sold at a loss. Smart stock rotation and seasonal transition planning prevent this costly mistake.
Why seasonal stock is so costly
The problem isn't just about shelf life. Winter products cost more because they come from greenhouses or imports. Spring arrives, prices drop for many products, but you're sitting with old stock at winter prices.
💡 Example:
You bought 10 kg of asparagus in February at €18/kg = €180
- In May, Dutch asparagus costs €8/kg
- Your old stock is still worth €180 on paper
- But guests expect seasonal prices
Loss: €10/kg × 10 kg = €100
The 3 biggest pitfalls with seasonal purchasing
1. Buying too much winter products in March
Winter's almost over, but you're purchasing like it's January. Check your sales data from last year: exactly when did demand for winter dishes stop?
2. No exit strategy for leftover stock
You know you need to switch to spring menus, but have zero plan for what remains. Result: ingredients you must dump at a loss - a mistake that costs the average restaurant EUR 200-400 per month.
3. Menus changed too late
You keep winter dishes on the menu too long because you still have ingredients. But guests already crave spring dishes.
⚠️ Watch out:
Never calculate with the purchase price of old stock. Calculate with current market price. Otherwise you'll appear profitable while actually losing money.
Plan stock rotation per season
6 weeks before seasonal switch:
- Check how much winter products you still have
- Calculate how much you still need until the switch
- Stop ordering seasonal products
4 weeks before seasonal switch:
- Introduce transition dishes that use up leftover stock
- Increase portions of winter dishes to burn through stock faster
- Consider special promotions on winter dishes
2 weeks before seasonal switch:
- Last chance: sell leftover stock to fellow restaurants
- Plan creative leftover dishes
- Start purchasing new seasonal products
💡 Example rotation strategy:
Restaurant with 100 covers/week, winter→spring transition:
- Week -6: Stop ordering pumpkin, endive, winter carrot
- Week -4: Pumpkin soup from €8.50 to €6.50
- Week -2: Remove last winter dishes from menu
- Week 0: Launch spring menus
Result: 90% less leftover stock than last year
How do you calculate your ideal closing stock?
The formula's simple: Closing stock = Weekly consumption × Number of weeks until seasonal switch
Add up what you still have in stock. Subtract what you still need. The difference is your surplus.
💡 Calculation example:
Butternut squash, 4 weeks before spring:
- Current stock: 25 kg
- Consumption per week: 8 kg
- Weeks until switch: 4
- Still needed: 4 × 8 = 32 kg
You're 7 kg short, not over! Order more.
Track seasonal stock digitally
With tools like KitchenNmbrs you can track per ingredient when you want to stop using it. Set reminders for 6 weeks before each seasonal switch.
The system can also alert you if stock value of certain products increases while the season's ending.
How do you plan seasonal rotation? (step by step)
Create an overview of seasonal products
List all ingredients that are typically winter, spring, summer, or fall. Note when the season roughly ends for each product. Use data from last year to see when demand stopped.
Calculate your ideal closing stock per product
Count how much you use per week of each seasonal product. Multiply by the number of weeks until the seasonal switch. This is your target closing stock.
Plan your exit strategy 6 weeks in advance
Stop ordering seasonal products. Introduce transition dishes or increase portions to get through leftover stock faster. Plan special promotions if you have too much.
✨ Pro tip
Start reducing winter stock purchases by 30% exactly 8 weeks before your spring menu launch. Most restaurants wait until 4 weeks, leaving them with €300+ in unsellable inventory.

Frequently asked questions
What do I do with leftover stock I can't sell anymore?
Three options: sell to fellow restaurants, make staff meals from it, or process it into new dishes. Don't throw it away - that's double loss.
How do I prevent having too little of new seasonal products?
Start buying new seasonal products 2 weeks before your menu switch. Test new dishes first with small quantities before stocking up on large amounts.
Do I have to sell seasonal products at a loss?
Sometimes. A small discount beats total loss. Calculate: what does it cost to throw away versus selling with a 20% discount?
