Guarantee agreement: definition and important aspects for buyers

A guarantee agreement protects companies from unexpected costs and strengthens the business relationship between supplier and buyer through clearly defined responsibilities. This structured guide shows you as a buyer how to draft legally compliant guarantee agreements and optimally safeguard your company's interests.

Guarantee agreement in a nutshell:

A warranty agreement is a legally binding contract in which the supplier voluntarily undertakes to guarantee certain properties or the functionality of a product for a specified period of time. For purchasing, this is an important tool for quality assurance and risk minimization, which has a positive impact on total cost of ownership.

Example: A machine manufacturer grants a 36-month warranty on all moving parts of a production system and contractually undertakes to send a technician on site within 24 hours of a fault being reported and to replace defective components free of charge.

Guarantee agreements: An introduction

The guarantee agreement is an important legal instrument in business transactions that is of great importance for both companies and consumers. It represents a voluntary assurance by the seller or manufacturer that goes beyond the statutory warranty. In today's world, where quality and customer satisfaction are key success factors, guarantee agreements are becoming increasingly important. They not only offer the buyer additional security, but can also serve as an important marketing tool. In this guide, you will learn all the important aspects of guarantee agreements, their legal basis as well as practical applications and structuring options.

What is a guarantee agreement?

A warranty agreement is a contractual agreement between the buyer and supplier in which the supplier provides certain guarantees regarding the quality, functionality or durability of the delivered goods or services. It serves as a guarantee for the buyer that the purchased product meets the agreed specifications and that any defects will be rectified within a defined period of time.

Core elements of a guarantee agreement

  • Warranty period: The specified period during which the warranty applies
  • Warranty services: Scope of the warranted services such as repair, replacement or refund
  • Conditions and exclusions: Specific conditions for eligibility and exclusion clauses
  • Procedure in the event of a warranty claim: Procedure for reporting and processing warranty claims
  • Significance for purchasing

    Warranty agreements play a crucial role in the procurement process to ensure the quality and reliability of the products or services supplied. They offer additional security to the purchasing department and minimize the risk of follow-up costs due to defective deliveries. Clear warranty conditions allow companies to better manage their suppliers and build long-term business relationships.

  • Quality assurance: ensuring that products meet requirements
  • Risk minimization: Reduction of financial risks through protection against defects
  • Supplier management: promoting responsibility and reliability on the part of suppliers
  • Sample template: Legally compliant guarantee agreement for your company

    Implementation of an effective guarantee agreement

    By including a clear guarantee agreement in the supplier contract, purchasing departments ensure the quality of the products purchased and minimize risks in the event of defects or failures.

    Practical example: Warranty for electronics deliveries

    A technology company procures 500 special chips for its products. In order to protect itself, the following warranty agreement is made with the supplier: Warranty period: 18 months from the date of delivery.

    Warranty services: Free replacement or repair of defective chips within 14 days.

    Conditions and exclusions: Valid for defects due to faulty materials or workmanship; excluded for damage due to improper storage or handling by the buyer.

    Procedure in the event of a warranty claim:
    • Report the defect with serial number and error description by e-mail within 5 working days of discovery.
    • Supplier will provide a return label within 2 working days.
    • After receipt and inspection, the supplier shall return replacement or repaired goods within 7 working days.
