Responsible purchasing charter: Heppner strengthens its commitments

Committed to a voluntary CSR approach, Heppner aligns its CSR ambitions with the sustainable development goals of the Global Compact and the principles of ISO 26000, and has begun to act ahead of the requirements of the French Climate and Resilience Act. To encourage suppliers and subcontractors to move in the same direction, the Group’s responsible purchasing charter has been revised in 2023. It sets out the framework for Heppner’s purchasing function and is an integral part of every contract awarded by the Group. It specifies Heppner’s commitments and expectations vis-à-vis its suppliers and subcontractors.

Stéphanie BERTHET, Purchasing Director, Heppner

We want our business relationships to  be consistent with our CSR strategy. Accordingly, we ask our  suppliers to undertake to abide by it and apply practices in their work that align with it and comply with current regulations and ethical principles. By signing our CSR Charter, the supplier engages both itself and  its subcontractors.”


Heppner has signed the responsible purchasing and supplier relations charter (RFAR)
Through 10 undertakings, this label issued by the French Ministry of Economy and Finance helps build a balanced, sustainable relationship between signatory companies and their suppliers. This voluntary, transparent future-looking initiative led by the Heppner Group is further proof of its determination to work towards more responsible, ethical and sustainable practices in its value chain. To meet this charter’s expectations, Heppner has appointed an internal mediator to resolve any conflicts that may arise between the company and its suppliers.

Heppner uses the Esker accounting solution
Rolled out in 2023, this 100% online solution will enable more efficient and responsible purchasing control and accounting. It will enable the Group to meet its payment deadlines, as well as streamlining exchanges between head office, the regional branches, and the subsidiaries.

Optimising and measuring the supplier experience

The supplier experience is a new strategic pillar defined by the Group in 2022. It is essential for establishing long-term partnerships that are beneficial to both parties. To achieve this, Heppner has committed to 6 pillars:

  • Administrative efficiency: simpler processes and visibility for its suppliers
  • Operational performance: operations optimisation to reduce production constraints
  • Recognition and consideration
  • Fluidity: smoother interactions with suppliers through a powerful management interface
  • Support: a long-term commitment to its suppliers, particularly in their transformation
  • Measurement: regular assessment of the supplier experience

In 2023, Heppner conducted its first NPS barometer among its suppliers
With nearly 1,400 respondents out of more than 18,000 suppliers (charterers, contractors) approached, this means that 6% of the suppliers expressed their views. The results were very positive, with an average NPS (Net Promoter Score) of 8.4/10 for the question “Would you recommend Heppner to a friend or business associate?”

Overall, 95% of respondents say they are satisfied with their professional relationship with Heppner.
This assessment process, with actions to improve the supplier experience, will continue in 2024.

Implementation of a supplier risk map

In order to assist buyers in assessing the suppliers and subcontractors used by Heppner, the Group has put in place an environmental, social and economic risk map. Structured as a criticality matrix (rated from 1 to 9) by type of purchase (transport subcontracting, vehicle purchase, IT purchase, telephone purchase, etc.) and complemented with the principles of product life cycle analysis, this risk assessment helps clarify decision-making.
