How can centralized purchasing be reconciled with local flexibility in multi-site catering?
April 29 2025For a long time, in multi-site catering, centralized purchasing was seen as a matter of course: economies of scale on volumes, nutritional harmonization, strict budget control, easier regulatory compliance.
However, the reality on the ground caught up with this model. Between local requirements (fresh supplies, expectations of short circuits), the specificities of establishments (diets, culinary cultures), CSR issues (carbon footprint, local supply chains), the rigidity of a single referencing system is now showing its limits.
The reality in the field has caught up with this model.

The challenge is therefore no longer to choose between centralization and local freedom, but to build a hybrid architecture, where rules are defined at the center, but agility is left to the sites. A new model of organization, demanding, but now unavoidable.
The structural limits of the 100% centralized purchasing model
Logistical tension
A single supplier can hardly guarantee consistent delivery times and conditions across an entire territory, particularly in rural, mountainous or outlying areas. As an example, an isolated EHPAD that receives its fruit in a single case rather than split delivery sees the freshness of its produce diminish, leading to waste and dissatisfied diners.
Tension over product suitability
A nationally referenced product may be unsuitable for certain sites: packaging too large, taste not adapted to regional expectations, or preparation complexity not compatible with the site's technical resources. The example of a dehydrated purée imposed on a top-of-the-range unit wishing to favor home-made products is sometimes revealing of these operational blockages.
Social and political tension
Societal expectations are evolving: local authorities, parents, associations are increasingly demanding local, organic, sustainable food. A purchasing policy that ignores this local dynamic risks coming into conflict with the communities it is supposed to serve.
The hybrid model: two-headed governance at the service of performance
Defining a clear national framework
It's essential to set national standards, such as minimum quality criteria, precise budget targets, or clear CSR expectations. This foundation makes it possible to unify practices while laying the groundwork for controlled flexibility.
Allowing controlled margins of autonomy
Sites must be able to adapt their sourcing within certain limits. Allowing establishments the ability to select certain products locally, as long as they meet the defined standards, is a major lever for combining efficiency and local roots. It may be appropriate to allocate a specific budget for these local purchases, or to provide for simplified validation of local suppliers.
Formalizing supply circuits
| Circuit | Description | Example |
|---|---|---|
| Centralized | Imposed product, single national supplier | Milks from a major industrialist |
| Semi-open | Standard products referenced framed local choice | Local fruit and vegetables validated |
| Local validated | Totally local products in addition to the national framework | Regional PDO cheeses in short circuits |
Meeting new challenges: short circuits, the EGAlim law and CSR
Short circuits and the EGAlim law
The EGAlim law requires 50% of food purchases to be sustainable or of high quality, including 20% from organic farming. This requirement obliges local producers to be included in procurement, or risk not being able to meet the new legal standards.
Flexibility in the face of CSR realities
Reducing carbon footprints can involve relocating food purchases. Working with local producers optimizes logistics, encourages sustainable agricultural practices, and meets the growing ecological expectations of consumers and communities.
Monitoring and control: reconciling freedom and the need for traceability
The essential tools
The success of a hybrid model relies on a purchasing IS capable of piloting both centralized and local circuits. Adoria enables this flexibility thanks to an integrated procurement platform, ensuring that all orders are tracked and consolidated.
Indicators to track
- Average basket compliance rate per site
- % of sustainable purchases and short circuits
- Supplier compliance rate
- Consolidated environmental impact
Reconciling centralization and local flexibility is no longer an option but a necessity. Tomorrow's multi-site collective catering will have to operate as an open platform, reconciling economic rigor, local adaptability, and societal demands.
