Operations and supply chain
We work on the factory floor, not in the boardroom.
Plinth is a business consulting firm of 34 people who fix delivery times, stock levels and margin for manufacturers and distributors between 50 and 500 million euro. Two weeks of looking before anyone says the word strategy.

Two weeks of looking before a single recommendation.
01
Two weeks of looking
We take your data and talk to twenty people, from the loading bay to the board. No recommendations in this phase, on purpose. Fixed price, whatever the size of the company.

02
A written diagnosis
One document: what is wrong, what it costs you a year, and what to start with. You own it whether or not you carry on with us.
One document, one session
03
Eight to twelve weeks of doing
Two of our people on site with your people. Changes are made in the operation, not in a slide deck, and they are measured while we are still there.
From €9,500 a week
04
A handover that holds
The numbers, the method and a named person on your side who can run it. We come back six months later for half a day, at no charge.
Free review at six months
How we charge
The fee is on the website, before you call.
Two weeks of looking has a price. So does a full engagement, and so does the month after it, when we are on the floor making sure the change held. No proposal theatre, no rate card you have to ask for.
Three numbers, and nothing hidden under them.
Prices in euro, excluding VAT. Travel at cost with receipts and no handling fee. We do not charge for proposals or for the first conversation.

Five things clients say after the first month.
Week one is on the floor, not in a meeting room.
One document, one session.
The diagnosis is a written document and a meeting, not a slide deck and a follow-up.
The two people you meet do the work.
No bait and switch to a junior team once the contract is signed.
Measured on the same line, six months later.
Stop any week.
Two weeks of notice, and we invoice only what has been done.
Three engagements, with the numbers the client signed off.
Where the work happens.
Six engagements from the last two years. The people in these photographs are the ones who run the line, not the ones who sign the contract.

The report always arrives after the decision
Why we do the looking before the writing, and what it costs a client when it is the other way round.

Count it. The system is lying to you.
In eleven of our last twelve inventory engagements, the physical count differed from the system by more than ten percent.

Read the contract before you change the carrier
Late deliveries are blamed on logistics. They are usually a clause nobody enforced.
