Supplier Definition: What Makes a Good Supplier?

Jörg Schmidt Head of Vendormanagement

Supplier management is extremely important for entrepreneurs and industrial companies, as it has a direct influence on the costs, quality and reliability of their own products and services. Careful supplier evaluation helps to minimize risks and build long-term, stable business relationships.

A supplier is a company or person that provides goods or services and sells or delivers them to customers - mostly other companies or businesses. Suppliers play a central role in the value chain by providing the required materials, products or services on time and in the desired quality.

The role of the supplier in the supply chain

Suppliers are at the center of every supply chain: they provide the required goods or services and sell them to companies that need them for their own products and production processes. In doing so, they have a significant influence on quality, availability and costs along the entire value chain. A reliable supplier base contributes to improved planning security for your own business processes and enables on-time production. In addition, reliable service providers minimize delivery failures and provide business partners with a consistent quality of their goods and services - an essential prerequisite for the competitiveness and innovative strength of companies in global markets.

Difference between supplier and manufacturer

There are differences betweensuppliers and manufacturers. Suppliers can also be intermediaries, wholesalers or resellers, while manufacturers produce the goods themselves. Here are the most important differences between producers and suppliers:

Manufacturer:
Manufacturesthe goods itself

Has its own production facilities
Often develops its own goods
Has a direct influence on quality and production processes

Supplier:
Does not necessarily produce itself - can also be a dealer or intermediary
Obtains its products from the manufacturer or third parties
Focuses on logistics, sales and procurement
Often supplies or represents several manufacturers

A good supplier makes a significant contribution to the smooth running of business operations. Reliability is one of the most important criteria. On-time delivery and transparent communication are crucial in order to avoid production downtimes or bottlenecks. The quality of the goods or services supplied is just as important. It not only influences the end products of the customers, but also customer satisfaction and the image of the company.

The price-performance ratio of suppliers is of great importance. A suitable supplier sells goods and services at competitive prices - without compromising on quality or service.

How does the supplier search work?

The search for suppliers is extremely important for successful cooperation. The following methods will help you to make a reliable supplier selection.

Strategies for an effective supplier search

As a buyer, a checklist is helpful, which contributes to the detailed determination of requirements. What are the exact requirements in terms of products, quantities, quality and delivery times? As soon as the requirements have been determined, the performance, cost-effectiveness and reliability of suppliers can be objectively included in the evaluation using ABC analysis, utility value analysis or scoring models .

The six-R rule when selecting suppliers

Die Sechs-R-Regel bei der Auswahl von Lieferanten

The six-R rule helps companies to identify the right source of supply: A first-class supplier ensures that the right goods are delivered at the right time, in the right quantity, to the right place, in the right quality at the right price. These characteristics are the foundation for reliable, efficient delivery and prevent delivery failures.
