Back to original languageAbout Marc-Antoine
Twelve years of reading company accounts, twenty-five years in purchasing. This combination has taught me one thing: leaders who lose margin on their suppliers often don't see it coming — because no one looks at purchasing and results at the same time.
This is what I do.
I support industrial SMEs and mid-sized companies that want to regain control over what they buy: suppliers, contracts, costs, conditions. Not to reduce at all costs, but to buy better, with less risk and measurable results.
My starting point: looking at what really exists — what we buy, from whom, under what conditions. Identifying what can be changed and quantifying the potential. Then acting: renegotiations, competitive bidding, secured contracts.
I work across the entire scope — raw materials, packaging, energy, transport, maintenance, services. Short-term or shared time format, depending on your needs.
I don't take on assignments without a clearly committed contact person on the client side. Not as a matter of principle — because without that, the results don't hold.
