AMC renewals: how service businesses lose money already earned

Four quiet ways a service firm loses AMC income, the register that shows every contract and visit, and a renewal routine that starts 60 days early.

4 min read · 25 Sept 2026

You serviced the machine well for a year, the AMC ended in March, and nobody called the customer. In July your technician attended a breakdown there free of charge, because "they are our AMC customer". That is earned money, lost for want of one date in one list.

Four quiet leaks

  1. Renewals nobody asked for. The end date is in a file. The contract lapses without a single call.
  2. Free service after expiry. The technician does not know the contract has ended, so the visit is not billed.
  3. Visits promised and not made. The AMC includes four visits. Two were done. At renewal the customer says, "You never came."
  4. Warranty ending without an offer. A good time to offer the first AMC is just before the warranty ends. Someone has to know that date.

AMC register format: one row per contract

Column What to write Why it matters
Customer and site Name, address, contact person, phone Who to call, where to go
Equipment Make, model, serial number, installation date The contract covers a machine, not a customer
Cover Warranty, comprehensive AMC (with parts) or non-comprehensive AMC (labour only) Decides what is free and what is billed
Start and end date Both dates Every reminder counts back from the end date
Amount and invoice AMC value, invoice number, paid or pending Renewed but unpaid is not renewed
Visits promised How many, and in which months The promise you made
Visits done A count, with the dates in the service log Your proof at renewal time
Breakdown calls A count, with the details in the service log Shows what the customer got for the money
Renewal status Not due, quote sent, renewed, lost with reason Your follow-up list
Next action date A date A contract without one is forgotten

Keep a second sheet as the service log: one row per visit or breakdown call, with the date, the contract, the technician, the service report number and the parts used.

An AMC renewal routine that starts 60 days early

  1. Every Monday: filter the register for contracts and warranties ending in the next 60 days, and do the step that is due for each.
  2. 60 days before: check the visits. If a promised visit is pending, do it now.
  3. 45 days before: send the renewal quote with a short service summary.
  4. 30 days before: call. Ask for a decision date and write it down.
  5. 15 days before: send a reminder with the date the cover ends.
  6. On the end date: mark the contract expired. Tell the service desk, and tell the customer politely that visits are chargeable from now.
  7. 15 days after: one last call. Then mark it lost, with the reason.

The service summary is what sells the renewal:

Namaste Mr Khanna. The AMC for your 10 kVA inverter (serial ending 4471) ends on 31 March. This year we made 4 service visits and attended 2 breakdown calls. The renewal quote is attached. Shall we continue from 1 April?

One check before every service call

When a complaint comes, the service desk looks at the register first: in warranty, in AMC, or expired. If the cover has expired, the customer is told the visit charge before the technician is sent. This one habit closes the free-service leak, and it can start the renewal talk as well.

Do not forget the invoice

A renewal agreed on the phone is not complete until the invoice is raised and paid. Put AMC invoices into the same routine as your other dues: see payment follow-up without spoiling relations.

Sheet or system?

An Excel register sorted by end date, opened every Monday, is enough for a few dozen contracts and one coordinator. It strains when contracts run into hundreds, when visits must be planned across several technicians, and when service reports come from the site as photos on WhatsApp. That is when we set up a Service & AMC Manager that keeps service calls, visits and renewal dates in one place.
