Cross-selling in purchasing: definition and important aspects for procurement specialists

Cross-selling opens up new opportunities for purchasing to generate additional savings and strengthen supplier relationships by cleverly bundling requirements. This structured overview shows you how you can systematically identify and successfully implement cross-selling potential in purchasing.

Cross-selling in a nutshell:

Cross-selling describes the strategy of purchasing additional, complementary products or services from a supplier that go beyond the original core business. For purchasing, this enables the use of existing supplier relationships to generate synergies and improved conditions through higher overall volumes.

Example: An automobile manufacturer expands its cooperation with an electronics supplier from pure control modules to display components, thereby achieving an additional volume discount of 7% on the total volume of EUR 2.5 million per year.

Introduction to cross-selling in purchasing

Cross-selling in purchasing is a strategic approach that is becoming increasingly important in modern procurement. It describes the practice of using existing supplier relationships to source additional products or services in order to achieve synergy effects. While cross-selling is traditionally known as a sales strategy, it also offers considerable potential for process optimization and cost savings in purchasing. In this guide, you will learn how cross-selling can be successfully implemented in purchasing and what benefits it can bring to your company.

What is cross-selling in purchasing?

Cross-selling in purchasing describes the strategy of purchasing additional, complementary goods or services from the same supplier in addition to the originally planned product. The aim is to increase the overall value of the business relationship and exploit synergies. By identifying requirements that can be covered by the supplier's extended range, companies benefit from more efficient procurement processes and potential cost savings.

Core elements of cross-selling in purchasing

  • Expansion of the product portfolio: purchase of additional articles that match the main product.
  • Bundling of suppliers: Reducing the number of suppliers by broadening the range offered by a single partner.
  • Intensive supplier relationship: building a strategic partnership for long-term cooperation.
  • Cost optimization: use of volume discounts and more efficient ordering processes.
  • Importance of cross-selling for purchasing

    Cross-selling offers considerable advantages for purchasing. By expanding the purchasing volume with a supplier, better conditions and discounts can be negotiated. In addition, the administrative effort is reduced due to fewer ordering and handling processes. Close cooperation with suppliers also promotes innovation and enables faster reactions to market changes.

  • Increased efficiency: Simplified processes thanks to reduced supplier diversity.
  • Strategic advantages: Stronger negotiating position and closer supplier loyalty.
  • Risk minimization: Secure supply through proven partnerships.
  • Practical guide: Successfully implementing cross-selling in purchasing

    Implementation of cross-selling in purchasing

    By identifying additional requirements and using the extended product range of existing suppliers, purchasing processes can be optimized and costs saved. Strategic cooperation with suppliers makes it possible to procure supplementary products or services and thus increase the overall value of the business relationship.

    Case study: Optimization through cross-selling of industrial components

    A mechanical engineering company regularly buys hydraulic cylinders from supplier X. The purchaser recognizes that Supplier X also has suitable hydraulic hoses and pumps in its range. Instead of purchasing these components from different suppliers, the purchaser negotiates with Supplier X to purchase all the required hydraulic components:

    1. requirements analysis: the purchaser checks the internal requirements for hydraulic components and identifies additional items required.

    2. supplier evaluation: checking whether supplier X can supply the additional products in the required quality and quantity.

    3rd negotiation: The buyer negotiates bundled prices and quantity discounts for the extended product range.

    4th implementation: Conclusion of a framework agreement for the supply of all hydraulic components by Supplier X.

    Result: Through cross-selling, the company achieves better conditions, reduces administrative costs and strengthens the relationship with supplier X. In addition, the supply chain is simplified and synergies are created in warehousing and logistics.
