Switching suppliers is like changing lanes in traffic - you need to calculate if the move actually gets you ahead faster. Many restaurant owners stick with familiar suppliers out of convenience, missing potential monthly savings of 15-20%. Here's how to crunch the numbers properly.
Why comparing suppliers pays off
Most restaurants rely on 3-5 core suppliers for meat, fish, vegetables and dry goods. That seemingly tiny €0.50 per kilo difference? At 100 kilos weekly, you're hemorrhaging €2,600 annually.
💡 Example:
You buy 50 kilos of beef per week:
- Current supplier: €18.50/kg
- New supplier: €16.80/kg
- Difference: €1.70/kg
Annual savings: €1.70 × 50 × 52 = €4,420
What factors to include in your calculation
Don't get fooled by headline prices alone. You need to compare the complete picture:
- Quality: Same grade meat, identical trim loss
- Minimum orders: Are you forced to buy excess quantities?
- Delivery costs: Free delivery thresholds matter
- Payment terms: 30 days vs. immediate payment
- Reliability: On-time delivery with consistent quality?
⚠️ Watch out:
A cheaper supplier with 20% higher trim loss costs you more in the end. Always test with a small trial order first.
Savings potential by product category
Different ingredients offer varying opportunities for cost reduction:
- Meat: 10-25% price variance between suppliers
- Fish: 15-30% difference, heavily seasonal
- Vegetables: 20-40% variance, especially seasonal produce
- Dry goods: 5-15% difference, more stable pricing
- Dairy: 8-18% spread between brands and private labels
I've seen restaurants overlook this simple comparison - a mistake that costs the average restaurant EUR 200-400 per month in unnecessary expenses.
💡 Example total calculation:
Restaurant with €8,000 monthly purchases:
- Meat (€3,000): 15% savings = €450
- Vegetables (€2,000): 25% savings = €500
- Fish (€1,500): 20% savings = €300
- Dry goods (€1,500): 10% savings = €150
Total monthly savings: €1,400 (€16,800 per year)
Calculate cashflow impact
Beyond direct price savings, supplier changes affect your working capital:
- Payment terms: 14 days vs. 30 days impacts cash availability
- Minimum orders: Higher minimums tie up more inventory capital
- Delivery frequency: Daily vs. twice weekly affects stock levels
Calculate your average inventory value before and after switching. Reducing inventory by €2,000 frees up €2,000 in working capital.
Factor in switching costs
Don't ignore the one-time expenses of changing suppliers:
- Time invested in comparing and testing new suppliers
- Different package sizes may require recipe adjustments
- Staff training on new supplier procedures and products
- Potential contract termination penalties with current supplier
💡 Payback period:
If switching costs €500 and you save €800 monthly, you'll recover costs in 3 weeks. Everything after that is pure profit.
Using tools like KitchenNmbrs for supplier comparison
Food cost calculators let you record multiple suppliers per ingredient with their current prices. You'll instantly see the cost difference per dish when switching suppliers. The system automatically recalculates your new food cost percentages.
How do you calculate supplier savings? (step by step)
Make a list of your top 20 ingredients
Get your purchase overview from the last 3 months. Sort by amount and select the 20 most expensive ingredients. These usually account for 80% of your total purchases.
Request quotes from at least 2 new suppliers
Send your list to potential suppliers and ask for prices including delivery costs and payment terms. Compare the same quality and package sizes.
Calculate the savings per ingredient
Formula: (Old price - New price) × Monthly consumption in kg. Add up all savings for your total monthly savings.
Test with a small order before switching
Order a week's supply from the new supplier. Check quality, delivery time and trim loss. Adjust your calculation if quality differs.
Calculate payback period of switching costs
Divide one-time switching costs by monthly savings. If this is less than 2 months, the switch is financially attractive.
✨ Pro tip
Focus your comparison on the 5 most expensive ingredients you purchase weekly. A 12% savings on high-volume items within 30 days typically delivers more impact than 20% savings across minor ingredients.

Frequently asked questions
How often should I compare suppliers?
Review your main suppliers at least twice yearly. Prices fluctuate due to seasonality, inflation and market shifts. Set calendar reminders for March and September to stay on top of changes.
Can I split orders between multiple suppliers simultaneously?
Absolutely - many restaurants use 2-3 suppliers per product category. This gives you negotiating leverage and backup options if one supplier fails. Just monitor minimum order requirements for each supplier.
Should I factor in VAT when comparing prices?
No, always compare excluding VAT since you can typically reclaim it. Focus on the net cost impact to your actual food expenses.
