Platform / MRO Purchasing

Ask anyone what you spend on MRO. Watch what happens.

Most plants can tell you their material cost to the penny and their MRO spend to the nearest shrug. It is one line on the P&L, it is bigger than anyone thinks, and not one person in the building can tell you where it went.

It still runs on a pad of three-part forms

Someone needs a cutting insert, a case of gloves, a pump seal. They walk to the office, pull a carbonless pad out of a drawer and fill out a requisition by hand. White copy to purchasing, yellow to the requester, pink stays in the book. Half the time the form is skipped entirely and it is a shouted request in the aisle, or a text message, or a note left on a keyboard.

Nobody is being careless. The form is faster than the alternative, and the alternative is nothing. But look at what that pad cannot do: it cannot tell you whether the same part was ordered last week, it cannot stop a $900 request going out under a $200 sign-off, and it cannot tell you, later, which machine ate the money.

Nobody actually authorized it

Ask who approved a given MRO purchase and you will usually get a name, a shrug, and no evidence. Approval in most small plants is a conversation. It happened, probably, and the person who had it is on the other side of the building.

That is not a governance problem to be solved with a policy nobody reads. It is a routing problem. A request for abrasives at forty dollars should not need the same signature as a nine-hundred-dollar pump, and the person who has to sign for the pump should not have to be at a desk to do it. Set the thresholds once, by value and by category, and the right request reaches the right person in seconds — with a record that still exists in a year.

• Approval that fits the amount

  Thresholds by value and category, so routine consumables clear without ceremony and real money gets a real look. The approver sees what it is, what it is for and which asset it is going against, and clears it from a phone between meetings.

• A record that outlives the conversation

  Who asked, who approved, when, at what amount, against which machine. Not to catch anybody out — to make the question answerable at all. Most plants cannot currently reconstruct a single MRO purchase from six months ago.

• Consumables on pull, not on memory

  Inserts, gloves, abrasives, filters and coolant do not need a decision every time. A bin goes empty, the reorder raises itself. Nobody has to notice, and nobody has to walk to the office with a pad.

• Supplier performance that accrues

  On time, complete, at the quoted price — recorded every time you receive something rather than reconstructed once a year when somebody asks. By the time you are renegotiating, the scorecard already exists.

One bucket, or a line you can act on

This is the part that pays for the rest. Today MRO is a single number on a monthly statement — real money, invisible inside itself. Attribute each purchase where it honestly belongs — an asset, a cell, a cost center, plain shop supply — and within a year the same spend answers questions it could never answer before.

Not everything belongs to a machine

This is where attribution schemes usually overreach, so let's be plain about it. A good deal of MRO has no honest home on a single asset, and forcing it onto one produces numbers that look precise and are quietly wrong — which is worse than not having them, because people act on them.

A case of nitrile gloves is shop supply. Nobody should be asked which machine wore them out. Consumable tooling is the harder case: inserts, drills, end mills and abrasives get shared across several machines and a dozen jobs, and in most shops the honest answer to which job consumed this insert is that nobody knows, and the cost of finding out comfortably exceeds the value of knowing it.

So the level is yours to set, per category. Assign to the asset where the link is real — a PM part, a spindle rebuild, a dedicated fixture. Assign to a cell, a department or a cost center where the spend is genuinely shared but still worth separating. Leave it as plain shop supply where that is simply the truth. What matters is not that everything reaches an asset. It is that nothing falls into one undifferentiated bucket by default, and that whatever level you picked gets applied the same way every time, so the comparison still means something a year from now.

The shop-supply line in the chart above is not the system failing to attribute something. It is a deliberate bucket, and on most floors it ought to be a healthy size.

Which is where maintenance comes back in

Where the link to an asset is real, it gets made at the moment of receipt rather than reconstructed later — and maintenance parts are the clearest case there is. Once that is true, maintenance and purchasing stop being two systems and start being one answer.

A PM that calls for a belt raises its own requisition. The part is received against the machine. A year later the maintenance history and the spend history are the same history, and the question that no small plant can currently answer — is this machine worth keeping? — has an actual number behind it instead of a feeling that it is always broken.

It also works the other way. The machine quietly consuming inserts at twice the rate of its twin is not a purchasing anomaly, it is a maintenance symptom, and you find it in the spend before you find it in a breakdown.

This is all MRO, not just maintenance parts

Worth being clear, because MRO gets read narrowly. This covers everything that is not the material you quote: tooling and inserts, abrasives and coolant, gloves and shop supplies, filters and belts, calibration, outside services, the things that arrive on a credit card today because there is no better route. Maintenance parts are one category inside it, and the one with the clearest link back to an asset — but a shop that only fixed its maintenance purchasing would still be blind to most of the money.

Take the piece you need

Purchasing is a module. Turn it on by itself if the spend is the thing keeping you up, or beside maintenance if you want the asset history to build from day one. The rest are there when you want them and out of your way when you don't.

All of it comes out of running plants rather than reading about them, which is why it is sized and priced for a shop your size instead of being an enterprise system with the expensive parts switched off.
