Establishing partnerships with our suppliers

Our suppliers and partners, an essential link in the Group's chain

At STEF, partners and suppliers play a crucial role in the Group's shared success.

We are committed to working with genuine partners throughout Europe to provide the best quality of service to our customers and the best working conditions for our employees.

As a French group and European leader, we support and promote local suppliers. Whether they are start-ups, very small businesses, SMEs or major corporations, we are committed to driving innovation with all our partners.  

Our commitments to our suppliers 

  • Creating a balanced and lasting partnership, respecting the best purchasing conditions: cost, quality, deadlines and services.
  • Developing innovative solutions tailored to our business in partnership with our suppliers.  
  • Offering our partners a European market.  
  • Making supplier invoicing paperless to be part of a sustainable approach, but also to ensure that our invoices are paid on time. . 


Our purchasing team selects our suppliers and monitors their performance according to criticality and/or turnover thresholds defined by STEF. It works closely with them and implements progress plans to encourage continuous improvement.

Our suppliers' commitments 

STEF places sustainable development at the heart of its strategy and considers it to be a lever for creating value for the Group and its stakeholders.  

We ask our suppliers and subcontractors to sign up to our Responsible Purchasing Charter, inviting them to respect a series of commitments:  

  • Reducing the environmental impact of activities 
  • Promoting and deploying social and civic practices 
  • Deploying innovative, high-performance and sustainable solutions  
  • Compliance with ethical rules, particularly in the fight against corruption 

Selection criteria 

Relations with our suppliers are based on respect for the values of our Group, in accordance with this charter. Partners and suppliers must have a proven track record in terms of operational reliability and compliance with shared commitments. They are selected on the basis of three criteria:

  • Performance 
  • Know-how  
  • Technological innovations
