Sample delivery: definition and important aspects for buyers

Sample delivery enables early quality assurance and creates trust between supplier and customer through the practical testing of products before series production. This structured guide shows you as a buyer how to efficiently design the sample delivery process and thus minimize risks and shorten development times.

Sample delivery to the point:

A sample delivery is the free or chargeable provision of product samples by a supplier for quality and suitability testing prior to a possible main order. For purchasing, this enables a well-founded assessment of product quality, processing properties and supplier performance before major investments are made.

Example: An automotive supplier has three potential suppliers deliver 50 plastic parts each as samples and carries out quality tests over 4 weeks before deciding on a supplier with an annual volume of 250,000 parts.

Introduction to purchasing controlling: sample delivery

Sample delivery is an important process in the context of quality assurance and product development. It enables companies to test and evaluate products or materials before actual series production or bulk purchasing. Sample deliveries allow potential problems to be identified and rectified at an early stage, saving both time and money. In this guide, you will learn all the important aspects of sample deliveries, from the legal basis and the process to best practices and quality assurance measures.

What are sample deliveries?

Sample deliveries are samples or test deliveries of products that a supplier makes available to a potential customer. In the procurement process, they are used to evaluate the quality, functionality and suitability of the product before a larger order is placed. By testing the samples, it can be ensured that the product meets the requirements and potential risks are minimized.

Core elements of sample deliveries

  • Product evaluation: analysis of quality, materials and workmanship
  • Functional testing: testing the products under real conditions
  • Customization options: Review the possibility of individual customization
  • Cost control: assessment of economic efficiency and value for money
  • Importance of sample deliveries in purchasing

    In purchasing, sample deliveries are a key tool for quality assurance and supplier selection. They enable purchasers to evaluate potential suppliers and ensure that the products offered meet the specific requirements. This supports strategic decisions and helps to optimize the supply chain.

  • Risk minimization: avoidance of incorrect orders through pre-testing
  • Supplier selection: Identification of reliable and high-quality suppliers
  • Process optimization: Increased efficiency through early product validation
  • Guide: Sample delivery - step by step to successful processing

    Implementation of sample deliveries

    Sample deliveries allow purchasing professionals to test products extensively before placing a large order. By analyzing samples, quality, functionality and suitability can be checked to ensure that the product meets specific requirements and potential risks are minimized.

    Practical example

    A mechanical engineering company is looking for a new supplier for precision bearings. The buyer contacts several potential suppliers and requests sample deliveries of the bearings. These samples are tested in the company's own workshop under real operating conditions:1. Quality inspection: Checking the material quality and workmanship of the bearings.

    2. Functional test: Installation of the bearings in existing machines and test run under full load.

    3. Longevity test: Accelerated ageing tests to estimate the service life.

    4. Customizability: Evaluation of the ability to customize bearings to meet specific requirements.

    After successful testing, the company chooses the supplier whose samples have passed all the tests. The buyer then places a bulk order and establishes a long-term business relationship.

    Evaluation and strategic findings

    ✓ Critical success factors

    → Standardized test procedures: Development of standardized testing processes for consistent assessments

    → Documentation quality: Complete recording of all test results as a basis for decision-making

    → Supplier communication: Clear coordination of expectations and requirements for sample deliveries

    ⚠ Challenges and limits

    → Cost management: balancing the scope of testing and the resulting sample costs

    → Time factor: Sufficient test phases vs. quick procurement decisions

    → Representativeness: Ensuring that samples reflect the series quality

    Future trends:

    "The digital transformation enables new ways of evaluating and managing samples"

    → Digital twins for virtual product tests

    → AI-supported quality analyses of samples

    → Blockchain-based traceability of samples

    → Automated documentation and evaluation

    ◆ Strategic implications

    → Risk minimization: Well-founded supplier selection through comprehensive sample tests

    → Quality assurance: early detection of potential quality problems

    → Process optimization: integration of sample testing into digital procurement processes

    Conclusion on supplier evaluation

    Sample deliveries are an indispensable tool in the modern procurement process. They enable a well-founded quality check, minimize procurement risks and support strategic supplier selection. Standardized test procedures and digital innovations continuously improve the efficiency of sample evaluation. The systematic use of sample deliveries makes a significant contribution to optimizing the entire supply chain and ensures the long-term success of the company.
