Strategic and Operational Consulting for Purchasing


During a first free purchasing audit we determine a diagnosic, recommendation and action plan.

In operational support, a consultant deploys part or all of the Purchasing process with our Customers (research, rating and qualification of a new supplier, preparation and launch of a call for tenders, negotiation and implementation of contracts, management of dispute). As an illustration, for the modernization of a plant of a petrochemical consortium, FlexBuy Concept took over the responsibility for the investments for a budget of 30 M€ with gains of 1.3 M€.

In strategic development, a performance expert is at your side to boost your added value and increase your results. For example, in an Alsatian mechanical SME, our action increased their net income by 27%.

FlexBuy Concept also offers transition management solutions in Purchasing during a vacant position or ad hoc support.

On request, we also provide you with various standard documents (calls for tenders, evaluation of offers, qualification of suppliers, framework contracts).

We can also support you in the search for candidates in your future recruitments.
