How do I calculate the costs of quality control when receiving a supplier delivery?

📝 KitchenNmbrs · updated 13 Mar 2026

Quality control on deliveries costs time and money, but prevents much bigger problems. Many hospitality entrepreneurs check their deliveries superficially, which means bad products end up in the kitchen. In this article you'll learn exactly how to calculate what quality control costs and why it pays for itself.

What are the costs of quality control?

Quality control on deliveries has three cost components: staff time, space for inspection, and potential returns. Most entrepreneurs only see the time, but forget about the other costs.

💡 Example:

Restaurant with 3 deliveries per day, inspection by sous chef (€18/hour):

  • Time per inspection: 15 minutes
  • Total time per day: 45 minutes = €13.50
  • Per month: €405
  • Per year: €4,860

Total quality control costs: €4,860 per year

Calculate the time costs of inspection

The biggest cost item is your staff's time. Calculate using the actual hourly wage including employer contributions (roughly 130% of gross hourly wage).

Time cost formula:
Time costs = (Minutes per inspection ÷ 60) × Hourly wage × Number of deliveries × Working days

💡 Example calculation:

Café with daily vegetable and meat deliveries:

  • 2 deliveries per day × 6 days = 12 per week
  • 10 minutes per inspection
  • Chef earns €15/hour gross = €19.50 actual costs

Weekly costs: (10 ÷ 60) × €19.50 × 12 = €39

Annual costs: €39 × 52 = €2,028

Costs of bad products

Without inspection, bad products end up in your kitchen. These costs are often higher than the inspection costs themselves. Think of products you have to throw away, dishes you have to remake, and unhappy guests.

  • Spoiled products you have to throw away
  • Time to get replacement product
  • Dishes you have to prepare again
  • Guest complaints about quality

⚠️ Note:

One batch of spoiled fish worth €200 costs you more than a month of quality control. Add to that the time to get new product and remake dishes.

Include return costs

Products that don't meet standards need to be sent back. This costs extra time and sometimes money too. Some suppliers charge fees for returns.

💡 Example return costs:

Pizzeria with weekly returns of €50 in products:

  • Time to handle return: 30 minutes = €9.75
  • Possible supplier return fees: €5
  • Time to order new product: 15 minutes = €4.88

Total costs per return: €19.63

ROI of quality control

Quality control pays for itself through less waste and better products. Calculate how much you save by refusing bad products.

ROI formula:
ROI = (Savings from inspection - Inspection costs) ÷ Inspection costs × 100

  • On average you prevent 2-5% waste through good inspection
  • With €100,000 annual purchases = €2,000-€5,000 savings
  • Inspection costs: usually €2,000-€4,000 per year
  • Net savings: €0-€3,000 per year

Digital registration of inspections

Many kitchens register their delivery inspections on paper or not at all. Digital registration in an app like KitchenNmbrs makes it easier to spot patterns and hold suppliers accountable for quality.

⚠️ Note:

Don't just register what goes wrong, but also what goes right. That way you can prove a supplier has structural problems and negotiate better prices or service.

How do you calculate quality control costs? (step by step)

1

Measure the time per inspection

Time how long you spend inspecting one delivery. Count everything: unpacking, checking quality, measuring temperature, and possibly setting aside products. A thorough inspection typically takes 10-20 minutes.

2

Calculate the hourly costs of inspection

Multiply the gross hourly wage of the person inspecting by 1.3 for employer contributions. A chef earning €15/hour actually costs €19.50 per hour. Calculate: (minutes ÷ 60) × hourly wage × number of deliveries per day.

3

Add return and waste costs

Estimate how much you spend per month on bad products you have to throw away or return. Add the time for handling returns and ordering replacement product. These are often the real costs.

✨ Pro tip

Don't just check what goes wrong, but also register good deliveries. That way you can prove which suppliers consistently deliver good quality and make better agreements with them.

Frequently asked questions

How much time should I spend inspecting deliveries?

A thorough inspection takes 10-20 minutes per delivery. Check temperature, expiration dates, damage, and quantities. This seems like a lot, but it prevents much bigger problems later.

What does quality control cost on average per year?

For an average restaurant this is between €2,000-€5,000 per year in staff costs. This depends on the number of deliveries, the size, and who does the inspection.

Does quality control pay for itself?

Yes, usually it does. You prevent 2-5% waste by refusing bad products. With €100,000 annual purchases you save €2,000-€5,000, which covers the inspection costs.

Do I need to inspect everything or can I do spot checks?

Always fully inspect fresh products (meat, fish, dairy). For dry goods you can do spot checks, but always check the packaging for damage.

What's the best way to register my delivery inspections?

Digital registration in an app like KitchenNmbrs is more convenient than paper. You can spot patterns, compare suppliers, and quickly look back at what went wrong when there are problems.
