Most restaurant owners discover their supplier strategy is bleeding money only after reviewing their first quarterly reports. Each additional supplier creates hidden costs in administration, delivery fees, and quality control that can easily exceed €10,000 annually. Here's how to calculate what those extra suppliers actually cost your operation.
What are logistics overhead costs?
Logistics overhead costs represent all hidden expenses that stem from your purchasing structure. You're not just paying for ingredient prices - you're funding an entire operational framework:
- Time to place and follow up on orders
- Delivery costs (minimum orders, transport costs)
- Administration (invoices, payments, quality control)
- Inventory costs (more suppliers = more safety stock)
- Quality control at each delivery
Calculate your time costs per supplier
Time equals money, period. Each supplier demands weekly attention for ordering, receiving, and administrative tasks - and that's the kind of thing you only learn after closing your first month at a loss.
💡 Example time calculation:
Per supplier per week:
- Placing order: 15 minutes
- Checking delivery: 10 minutes
- Processing invoice: 5 minutes
- Contact/issues: 10 minutes
Total: 40 minutes per supplier per week
At €30 per hour (your worth as a business owner), each supplier costs €20 weekly in time. That's €1,040 annually per supplier.
Calculate delivery costs and minimum orders
Small suppliers typically impose higher minimum orders or delivery fees. This forces you to purchase beyond your actual needs.
💡 Example delivery costs:
Small fish supplier:
- Minimum order: €200
- You need €120 in fish
- You must buy €80 extra
- That sits in inventory for 1 extra week
At 2% interest per month = €1.60 extra cost per order
Run this calculation for every small supplier. Total up how much "excess" purchasing you're forced into weekly just to meet minimums.
Compare with large suppliers
Large suppliers benefit from economies of scale that directly reduce your logistics burden.
💡 Example large supplier:
Large wholesaler:
- Minimum order: €500, but broad assortment
- Free delivery from €300
- Online ordering system (5 min instead of 15 min)
- Less chance of out of stock/delays
Time savings: 20 minutes per week = €10
Calculate the full picture
Build a complete cost overview for each supplier structure:
10 small suppliers:
- Time costs: 10 × €1,040 = €10,400/year
- Extra inventory costs: €3,000/year
- Delivery costs/minimum orders: €2,500/year
- Total: €15,900/year
2 large suppliers:
- Time costs: 2 × €800 = €1,600/year
- Extra inventory costs: €800/year
- Delivery costs: €500/year
- Total: €2,900/year
⚠️ Note:
This represents pure logistics overhead. Small suppliers might offer superior quality or unique products. Factor that value into your final decision.
When many suppliers still make sense
Sometimes those extra costs deliver real value:
- Specialty restaurant: Unique ingredients that only small suppliers carry
- Quality difference: If a small supplier delivers noticeably better quality
- Seasonal products: Local farmers for fresh, seasonal ingredients
- Backup strategy: Spreading risk in case of supply problems
Then determine whether the quality or uniqueness advantage justifies the €13,000 overhead from our example.
Digital tools
Systems like tools like KitchenNmbrs centralize supplier information and pricing data. You'll instantly see which supplier offers the lowest cost per ingredient, including your logistics expenses.
How do you calculate logistics overhead? (step by step)
Measure your time per supplier
Track for 2 weeks how much time you spend on each supplier. Add up ordering, receiving, checking and administration. Multiply by your hourly rate.
Calculate extra inventory costs
Check your minimum orders versus actual needs. Calculate how much extra you buy and how long it sits in inventory. Calculate 2% interest per month on excess inventory.
Compare total costs per scenario
Add up time, inventory and delivery costs for your current situation. Do the same for a scenario with fewer suppliers. The difference is your logistics overhead.
✨ Pro tip
Track your actual ordering time for 3 weeks across all suppliers, then multiply by €30/hour to see your real labor costs. Most owners underestimate this by 40-60%.

Frequently asked questions
How do I calculate my own hourly rate?
Divide your desired annual income by 1,800 working hours (36 hours × 50 weeks). At €54,000 desired income that's €30/hour. Factor in employer taxes and benefits too.
What if small suppliers have cheaper purchase prices?
Offset the price difference against logistics overhead. If you save €2,000 annually on purchases but spend €5,000 more on logistics, you're losing €3,000. The math doesn't lie.
How often should I recalculate this analysis?
Review annually or whenever your supplier structure changes significantly. Prices shift and your hourly rate evolves, so the calculations need updating.
What are typical minimum orders in hospitality?
Large wholesalers: €300-500. Small suppliers: €150-300. Specialty suppliers: €100-200. Regional variations are common.
Can I negotiate minimum orders with suppliers?
Often yes, especially with established relationships. Request lower minimums in exchange for slightly higher unit prices, or coordinate orders with nearby restaurants.
Should I factor in food waste when comparing suppliers?
Absolutely. If minimum orders force you to overstock perishables, calculate spoilage costs at roughly 3-8% of excess inventory value. This can add hundreds to your annual overhead.
How do I handle suppliers who only accept cash payments?
Add administrative burden costs: bank trips (30 minutes weekly), cash handling time, and lost payment terms benefits. Cash-only suppliers typically cost an extra €15-25 weekly in hidden expenses.
