What's the real financial impact of switching your supplier strategy? Loose suppliers charge higher prices but offer flexibility, while fixed suppliers provide discounts in exchange for commitment. You need to calculate exactly what this switch means for your bottom line.
Why supplier choice affects your margin
Your supplier strategy directly controls your food cost percentage. Loose suppliers give you freedom but charge premium prices. Fixed suppliers slash costs but demand commitment.
? Example:
Restaurant with €40,000 monthly revenue, 30% food cost:
- Current purchasing: €12,000/month
- Fixed supplier offers 8% discount
- Savings: €12,000 × 0.08 = €960/month
Annual savings: €11,520
The hidden costs of loose suppliers
Loose suppliers appear flexible, but they're expensive in ways you might not realize:
- Premium pricing: Usually 10-20% higher than contract rates
- Delivery fees: No free shipping below minimum orders
- Administrative burden: Constant calling and price comparison
- Inconsistent quality: Products vary between orders
The advantages of fixed suppliers
Fixed suppliers deliver measurable benefits:
- Volume discounts: Typically 5-15% below market prices
- Free shipping: Once you hit minimum order thresholds
- Extended terms: 14-30 day payment windows
- Quality consistency: Standardized products and service
⚠️ Note:
Fixed suppliers typically require minimum purchases. Verify you'll actually use this volume, or you'll increase waste instead of saving money.
Step 1: Calculate your current purchasing costs
Build a breakdown of your monthly spend by product category:
- Meat and fish
- Vegetables and fruit
- Dairy and eggs
- Dry goods
- Beverages
? Example calculation:
Monthly purchases per category:
- Meat/fish: €4,500
- Vegetables: €2,800
- Dairy: €1,200
- Dry goods: €1,800
- Beverages: €1,700
Total: €12,000/month
Step 2: Compare contract prices
Get quotes from at least 3 fixed suppliers. Focus on these factors:
- Net pricing: Compare prices excluding VAT
- Order minimums: Per item and per total order
- Delivery schedule: How frequently can you order?
- Payment terms: Days until payment is due
Calculate the margin impact
Apply this formula to determine the financial effect:
Monthly impact = (Current purchasing costs - New purchasing costs) - Additional expenses
? Complete calculation:
Scenario: €12,000 monthly purchases, fixed supplier 10% cheaper:
- Purchasing savings: €12,000 × 0.10 = €1,200
- Extra storage costs (increased inventory): €200
- Net savings: €1,200 - €200 = €1,000/month
Margin improvement: €1,000 / €40,000 revenue = 2.5 percentage point reduction in food cost
Include cashflow impact
Factor in the cashflow implications:
- Payment terms: 30-day terms vs. immediate payment improves cashflow
- Inventory investment: Larger orders tie up more working capital
- Storage requirements: Adequate refrigeration and dry storage space needed
From years of working in professional kitchens, I've seen restaurants underestimate storage costs and end up with spoiled inventory that wipes out their supplier savings.
Scenarios where loose suppliers work better
Stick with loose suppliers in these situations:
- Seasonal operations with variable volume
- Testing new menu items and ingredients
- Constrained storage capacity
- Tight cashflow situations
How do you calculate the margin impact? (step by step)
Inventory your current purchasing costs
Create an overview of your monthly purchases per product category. Add up all receipts and invoices from loose suppliers. Also note extra costs such as delivery costs and administrative time.
Compare contract prices
Request quotes from at least 3 fixed suppliers. Pay attention to net prices, minimum purchases, delivery frequency and payment terms. Calculate what your total monthly purchases would cost with each supplier.
Calculate net impact on margin
Subtract new purchasing costs from old purchasing costs. Add extra costs (storage, administration). Divide the difference by your monthly revenue to see the impact on your margin.
✨ Pro tip
Test your margin calculations with a 90-day trial contract before committing long-term. Track your actual food cost percentage weekly during this period to verify the projected 2-3% margin improvement.
