Single sourcing: definition & important aspects

As a strategic procurement approach, single sourcing enables a close partnership with a selected supplier and thus creates considerable competitive advantages. The following overview shows you how you can make the most of the potential of this procurement strategy for your purchasing department and avoid typical risks.

Single sourcing in a nutshell:

Single sourcing describes the strategic decision to purchase a specific item or group of goods exclusively from a single supplier. For purchasing, this enables closer supplier relationships, better conditions and simplified processes, but also entails increased dependency and default risks.

Example: An automobile manufacturer procures all control units for a vehicle series exclusively from a specialized electronics supplier and achieves a cost saving of 22% compared to a multi-sourcing strategy thanks to the bundled annual volume of 50,000 units.

What is single sourcing?

Single sourcing refers to the practice of using only one supplier for a specific product or service. In contrast to multi-sourcing, where several suppliers are used in parallel, single sourcing focuses on a close partnership and continuous cooperation with a selected supplier.

Advantages in detail:

  • Cost optimization: By concentrating orders with one supplier, volume discounts and more favorable payment terms can be negotiated, which reduces the overall cost of procurement.

  • Quality assurance: Close cooperation makes it possible to define precise quality standards and monitor them continuously, thereby improving product quality.

  • Simplified communication: Fewer suppliers mean fewer communication channels, which speeds up coordination and problem solving and increases efficiency.

Implementation steps:

  1. Supplier selectionCareful evaluation of potential suppliers based on criteria such as quality, reliability, costs and innovative ability.
  2. Contract managementConclusion of clear contracts that define delivery conditions, quality standards and exclusivity in order to avoid misunderstandings.
  3. Relationship management: building a relationship based on partnership through regular meetings, transparent communication and joint objectives.

Risks and challenges:

  • Supply bottlenecks: Dependence on a single supplier can be problematic if that supplier fails or has delivery problems.

  • Market changes: Changes in the market or suppliers can limit flexibility and require adjustments.

  • Negotiating power: Less competition can affect the ability to negotiate prices and enforce favorable conditions.

Best Practices:

  • Risk managementDevelopment of contingency plans and alternative procurement strategies in order to be able to react to unexpected supply bottlenecks.

  • Regular evaluation: Continuous review of supplier performance and adjustment of strategy as necessary to ensure efficiency and quality.

  • Technological support: Use of procurement software for better monitoring and control of the supply chain, which increases transparency and efficiency.

Single sourcing: from a traditional approach to digital single sourcing

Building on the concept of single sourcing, where a company chooses only one supplier management for a specific product or service, its practical implementation is becoming increasingly important in modern business. In traditional structures, single sourcing offered benefits such as procurement costs and quality improvements through close collaboration. However, the increasing complexity of global supply chains and the need for fast response times require this approach to evolve. The transformation to digitally integrated models addresses these challenges and enables more efficient, transparent processes.

Conclusion: Single sourcing as a strategic procurement method for sustainable success

Single sourcing offers buyers an effective way of optimizing procurement processes, reducing costs and ensuring the quality of the products or services purchased. By working closely with a selected supplier, long-term partnerships can be established that lead to sustainable business success. However, it is essential to carefully manage potential risks such as dependencies and supply bottlenecks. With the right strategies and proactive risk management, single sourcing can be a valuable addition to any buyer's toolbox and contribute significantly to the company's efficiency and competitiveness.
