How do I calculate the benefits of an annual contract with a supplier?

📝 KitchenNmbrs · updated 13 Mar 2026

An annual contract with your supplier can save you thousands of euros. Many restaurant owners miss out on discounts by paying per order. In this article you'll learn exactly how to calculate what an annual contract will bring you.

What are the benefits of an annual contract?

An annual contract with suppliers usually offers three major benefits: discounts on purchase prices, fixed prices throughout the contract, and priority during busy periods.

  • Volume discount: 3-8% discount on your total purchases
  • Price certainty: No surprises from seasonal fluctuations
  • Delivery guarantee: Priority during shortages
  • Better payment terms: Often 30 days instead of immediate payment

Calculate your current annual purchases per supplier

For a good calculation you need your purchase data from the past year. Check your administration or POS system for the exact amounts per supplier.

💡 Example:

Restaurant 'The Taste' purchases annually from supplier ABC:

  • Meat: €45,000
  • Fish: €18,000
  • Vegetables: €22,000
  • Dairy: €12,000

Total annual purchases: €97,000

Calculate the potential savings

Most suppliers offer 3-8% discount on an annual contract, depending on your purchase volume. Larger restaurants often get more discount.

💡 Savings calculation:

At €97,000 annual purchases and 5% discount:

  • Annual savings: €97,000 × 0.05 = €4,850
  • Monthly savings: €4,850 ÷ 12 = €404
  • Weekly savings: €4,850 ÷ 52 = €93

That's almost €100 per week in purchase cost savings!

Factor in the risks too

An annual contract also has disadvantages that you need to include in your calculation. You're locked in with one supplier and can't benefit from temporary offers from others.

⚠️ Watch out:

Check if your contract has an exit clause for poor delivery or quality issues. Without an exit clause you're locked in for a year, even if service deteriorates.

Compare with your current situation

Add the 'hidden costs' to your current purchase costs: time spent on multiple orders, administration for different suppliers, and missed discounts.

  • Time savings: 1-2 hours per week less ordering
  • Administration: Fewer invoices and payments
  • Inventory optimization: Better planning possible

💡 Calculate total savings:

Example of total annual savings:

  • Volume discount: €4,850
  • Time savings (2h/week × €25/hour × 52 weeks): €2,600
  • Reduced administration costs: €500

Total savings: €7,950 per year

Negotiate the terms

Use your calculation as a negotiating tool. Show what you purchase annually and ask for the best terms. Many suppliers have room to negotiate.

Ask specifically about discount percentages per product group. Sometimes you get more discount on meat than on vegetables, depending on their margins.

How do you calculate the benefits of an annual contract? (step by step)

1

Gather your annual purchases per supplier

Check your administration for the total purchases from the past year per supplier. Add up all invoices and break them down by product group (meat, fish, vegetables, etc.).

2

Request quotes for annual contracts

Contact your current suppliers and ask about their annual contract terms. Ask specifically about discount percentages, price guarantees and delivery conditions.

3

Calculate the total savings per year

Multiply your annual purchases by the discount percentage. Add the time savings and administration benefits for the complete picture.

✨ Pro tip

Don't just negotiate on discount, but also on payment terms. 30 days payment terms instead of immediate payment can significantly improve your cash flow.

Frequently asked questions

What is a realistic discount percentage on an annual contract?

Most suppliers offer 3-8% discount on annual contracts. Large restaurants with high volumes can sometimes get 10-12% discount. It depends on your purchase volume and product group.

Can I exit an annual contract if the supplier performs poorly?

That depends on your contract. Always make sure you have an exit clause for poor delivery, wrong products or quality issues. Without an exit clause you're locked in for a year.

Do I need to put all my suppliers on annual contracts?

Not necessarily. Focus first on your largest suppliers where you spend the most. For small suppliers (less than €10,000/year) the savings are often too small to justify the inflexibility.

What about seasonal products in an annual contract?

Many suppliers use seasonal pricing, even in annual contracts. Check if your contract has fixed prices or seasonal adjustments. Fixed prices give more certainty for your cost price calculations.

Can I still get special offers with an annual contract?

That varies by supplier. Some give extra discounts on top of your annual contract, others don't. Ask about this explicitly during negotiations.
