Daily purchasing or one large weekly delivery? This question keeps many restaurant owners up at night. Small deliveries cost more time, but large deliveries mean more inventory and spoilage risk.
Comparing the two purchasing strategies
There are two main strategies for purchasing: frequent small deliveries versus one large weekly delivery. Both have pros and cons that you can express in euros.
💡 Example comparison:
Restaurant with 150 covers per week:
- Daily purchasing: 6 deliveries per week
- Weekly delivery: 1 delivery per week
- Average order: €800 per delivery
Calculate the real costs per strategy
To make the right choice, you need to include all costs. Not just the purchase price, but also hidden costs like time, spoilage, and administration.
Costs of daily deliveries
- Time per delivery: 30 minutes checking, storing, administration
- Delivery costs: Often free above minimum order, otherwise €15-25 per delivery
- Administration: 6× invoice processing per week
- Inventory risk: Low (1-2 days inventory)
💡 Calculation daily deliveries:
- Time: 6 × 30 min = 3 hours per week × €25/hour = €75
- Delivery costs: 6 × €0 (above minimum) = €0
- Extra administration: 5 × 10 min × €25/hour = €20
- Spoilage: 2% of purchases = €96
Total extra costs: €191 per week
Costs of weekly delivery
- Time per delivery: 90 minutes for large delivery
- Delivery costs: Usually free with large orders
- Administration: 1× invoice per week
- Inventory risk: High (7 days inventory)
- Storage space: More cooling/freezer capacity needed
💡 Calculation weekly delivery:
- Time: 1 × 90 min = 1.5 hours × €25/hour = €38
- Delivery costs: €0 (above minimum)
- Spoilage: 8% of purchases = €384
- Extra cooling energy costs: €25
Total extra costs: €447 per week
⚠️ Note:
Spoilage is often the biggest cost item. With weekly delivery you have 7 days of inventory, which greatly increases the risk of spoilage and overproduction.
The formula for your situation
Use this formula to calculate which strategy is more cost-effective for your restaurant:
Daily costs = (Number of deliveries × Time per delivery × Hourly rate) + (Number of deliveries × Delivery costs) + (Weekly purchases × Low spoilage percentage)
Weekly costs = (Time for large delivery × Hourly rate) + Delivery costs + (Weekly purchases × High spoilage percentage) + Extra storage costs
Daily purchasing makes more sense if...
- You have limited storage space
- You sell many fresh products (fish, meat, vegetables)
- Your menu changes regularly
- Your supplier doesn't charge delivery costs for small orders
- Your team has time for daily checks
Weekly delivery works better for...
- You have sufficient cooling and freezer space
- You sell many shelf-stable products
- Your menu is stable
- Your supplier charges high delivery costs for small orders
- Your time is scarce for administration
💡 Hybrid approach:
Many restaurants combine both strategies. Dry goods and frozen weekly, fresh daily. This gives you the benefits of both systems while minimizing drawbacks - one of the most common blind spots in kitchen management is thinking it's an either/or decision.
Tools to keep track of this
A food cost calculator (like KitchenNmbrs) helps you track purchasing costs per supplier and analyze which strategy really works out cheapest. You'll see the difference in spoilage and total costs per week directly.
How do you calculate which purchasing strategy is more cost-effective?
Calculate your current costs per week
Add up: purchase amount + time × hourly rate + delivery costs + spoilage. Do this for at least 4 weeks to get an average.
Estimate the costs of the alternative strategy
Calculate how much time, delivery costs, and spoilage the other strategy would cost. Pay special attention to the difference in spoilage percentage.
Test the more cost-effective option for 2 weeks
Try the strategy that looks more cost-effective on paper. Track: actual time, spoilage, and any problems. Then make permanent adjustments.
✨ Pro tip
Track your actual spoilage percentages for 30 days before making the switch. Calculate delivery costs as (number of weekly deliveries × €20) if you're below minimum orders - this often tips the scales toward weekly purchasing.

Frequently asked questions
What's the average spoilage percentage with daily versus weekly purchasing?
With daily purchasing, spoilage usually falls between 2-5% of the purchase value. Weekly purchasing can see spoilage rise to 8-12% due to longer storage and more difficult planning. Fresh proteins and produce show the biggest difference.
Should I factor in delivery costs to my calculation?
Absolutely - delivery costs are crucial. Many suppliers charge €15-25 per delivery below a minimum order. With 6 deliveries per week this adds up to €600+ monthly.
How do I calculate the time purchasing costs me?
Budget 20-30 minutes per small delivery and 60-90 minutes per large delivery. This includes checking, storing, and administration. Multiply by your hourly rate or that of your chef to get true costs.
Can I combine different strategies per product group?
Yes, many restaurants do this successfully. Fresh products daily, dry goods and frozen weekly. This approach combines benefits of both systems while minimizing drawbacks.
Do seasonal fluctuations affect which strategy works better?
Definitely - summer months with higher fresh produce spoilage rates often favor daily deliveries. Winter might allow for more weekly purchasing due to longer shelf life and stable demand patterns.
Should I reconsider my purchasing strategy regularly?
Review your strategy with major changes: new suppliers, different menu, significant guest count shifts, or structural spoilage changes. Check this at least twice yearly to ensure you're optimizing costs.
