How much money is actually sitting in your walk-in cooler right now? Most restaurant owners can't answer that question without an inventory sheet - a detailed record of every product in your kitchen with current quantities and values. Without this crucial document, you're essentially flying blind through food costs, overordering, and spoilage.
What's on an inventory sheet?
Every effective inventory sheet needs these core data points for each product:
- Product name - Clear and specific
- Unit - Kg, liter, pieces, cans
- Current inventory - What do you have right now?
- Purchase price per unit - Last known price
- Total value - Quantity × price
- Minimum level - When do you need to reorder?
- Supplier - Who do you order from?
? Example inventory sheet:
- Beef entrecote: 12 kg × €24.50 = €294.00
- Salmon fillet: 8 kg × €32.00 = €256.00
- Olive oil: 6 bottles × €8.50 = €51.00
- Onions: 25 kg × €1.20 = €30.00
Total inventory value: €631.00
Why an inventory sheet is crucial
Here's a pattern we see repeatedly in restaurant financials: owners estimate their inventory at €3,000, but actual counts reveal €8,000 worth of products. That's €5,000 in cash flow you didn't even know was tied up in your storage areas.
- Prevent overordering - You only order what you need
- Less spoilage - You see what needs to be used quickly
- Better cash flow - Less money tied up in inventory
- No emergency orders - You know when to reorder
⚠️ Heads up:
Your inventory sheet only works if it's current. Last month's numbers won't help you make today's ordering decisions.
Digital vs paper inventory sheet
Paper sheets become obsolete the moment you use an ingredient. Digital tools like KitchenNmbrs calculate values automatically and send low-stock alerts to your phone.
- Paper: Cheap, but quickly outdated
- Excel: Flexible, but lots of manual work
- App: Automatic calculations and alerts
? Example savings:
Restaurant with €6,000 inventory value per week:
- 10% less overordering = €600/week savings
- 5% less spoilage = €300/week savings
Total: €46,800 per year
How often should you count inventory?
Your counting frequency should match product shelf life and value:
- Daily: Fresh products (fish, vegetables, dairy)
- Weekly: Meat, frozen, dry products
- Monthly: Canned goods, oils, spices
Focus on your 20 highest-value ingredients weekly. You'll capture 80% of your inventory value while spending just 20% of the time a full count requires.
? Practical example:
Monday morning 9:00 - inventory count:
- Refrigerator: count fresh products (15 min)
- Freezer: inventory meat and fish (10 min)
- Dry storage: quick scan (5 min)
Total: 30 minutes for complete overview
How do you create an inventory sheet? (step by step)
Inventory all products
Walk through your entire kitchen and note everything you have in stock. Start with the refrigerator, then freezer, then dry storage. Note exact quantities and units.
Gather purchase prices
Look up your latest invoices from suppliers and note the price per unit. If you don't have an invoice, call your supplier for the current price. This is crucial for accurate valuation.
Calculate total value per product
Multiply the quantity by the purchase price per unit. Add up all products for your total inventory value. This amount is tied up in your kitchen and isn't working for your business.
Set minimum levels
Determine per product when you need to reorder. Calculate how much you use per week and account for your supplier's delivery time. This prevents you from running out.
Create an update routine
Schedule fixed times to update your inventory sheet. For example, every Monday morning or after each delivery. Without a routine, your sheet becomes useless.
✨ Pro tip
Count your inventory every Tuesday at 2 PM for 4 weeks straight - same day, same time. This builds the habit and gives you consistent data points to spot ordering patterns and waste trends.
