AMC and warranty coordination

What AMC and warranty coordination actually means

It is the job of knowing, at the moment a machine stops, who is liable to fix it — the vendor under annual maintenance contract, the OEM still inside warranty, or you. Get it right and the call goes to whoever owes you the repair. Get it wrong and you pay a bill you were never liable for, which is the everyday cost of running this on paper.

In most plants the answer lives in three places at once: a contract file in the accounts cabinet, a warranty card in the machine's original carton, and the memory of whoever bought it. When a machine stops at nine at night, none of those are available, so the supervisor calls the vendor who answers and the plant pays.

Where it goes wrong, and what each mistake costs

Four failures account for almost all of it:

• Paying for a covered repair. The commonest and the least visible. Nobody checks because checking takes twenty minutes, and the invoice looks ordinary when it arrives.
• Missing the renewal. Cover lapses on a Friday, the machine fails on a Monday, and the same vendor now quotes for the repair at commercial rates.
• Calling the wrong vendor. A plant running three AMC vendors across compressors, DG sets and material handling will eventually call the one who has the friendliest engineer rather than the one under contract.
• Losing the claim window. Many OEM warranties require the fault to be reported within days, with the serial number and the running hours. Report it late, in the wrong format, and the claim is refused on process rather than on merit.

None of these show up in a monthly review. They show up as a maintenance budget that is quietly ten to fifteen percent higher than it needs to be.

What good coordination looks like

It is four habits, not a department:

1. Coverage on the asset record, not in a file. Vendor, contract number, start and end dates, what is included, and what is expressly not.
2. The check happens automatically at the moment of the call. If the person raising the job has to look coverage up, they will not, at ten at night.
3. Renewals surface before they expire, not after. A warning window long enough to negotiate, not long enough to forget.
4. Every visit and every claim recorded against the contract. So at renewal you know what the vendor actually delivered, which is the only thing that gives you a position in the negotiation.

AMC and warranty are not the same thing

They get coordinated together and confused constantly.

Warranty comes with the machine, is paid for in the purchase price, and is the OEM's obligation. It is time-bound, often running-hours-bound, and usually excludes consumables, wear parts and anything the OEM can attribute to misuse or poor upkeep. It is the reason a PM record matters: the first question in a contested claim is whether you maintained it as specified.

An AMC, an annual maintenance contract, is something you buy separately, usually after warranty ends. Comprehensive AMCs include parts; non-comprehensive ones cover labour and visits while you pay for spares. The difference between those two is the single largest variable in an Indian plant's maintenance spend, and it is worth having written on the asset record rather than remembered.

A machine can be under both, neither, or a warranty extension that behaves like an AMC. Coordination means the plant knows which, per machine, today.

How AssetAI does it

The coverage lives on the asset, so the check happens where the work starts rather than in a file somebody has to remember to open.

• On the asset record — vendor, contract reference, cover type, start and end dates, what is included, running-hours limit where the OEM sets one.
• At the moment a job is raised — the work order shows the coverage state before anybody calls anyone. Under AMC, under warranty, or on us, with the vendor's name.
• On the bill — a repair invoice against a covered machine is flagged rather than approved quietly, which is where the money is actually saved.
• Before it lapses — expiry warnings with enough notice to negotiate the renewal or decide to let it go.
• At renewal — every visit, breakdown and claim against that contract in one place, so the conversation is about what was delivered, not about what each side remembers.

Getting the contract data in without a three-month project

The obstacle is never the software, it is that nobody has the current list. A practical sequence:

1. Start with the machines where a repair actually hurts: the bottleneck line, the DG sets, the compressors, anything imported.
2. For each, capture only five fields: vendor, contract number, cover type, end date, and whether spares are included. Everything else can follow.
3. Take renewals as they come. Any contract renewed after go-live gets entered properly at renewal, so the register completes itself within a year without a data-entry exercise.
4. Leave uncovered machines visibly uncovered. A blank is information: it says this machine is on us, which is exactly what the supervisor needs to know at nine at night.

What this does not do

It does not file your claims, chase your vendor, or negotiate your renewal. It does not tell you whether an AMC is worth buying, which is a judgement about criticality and spare availability, not a calculation. And it will not rescue a claim already refused.

What it does is make sure the plant knows the answer at the moment the question is asked, and that the answer is on a record rather than in somebody's memory.
