AMC Management: Contracts, Coverage, Renewals and Billing
Annual maintenance contracts are steady revenue, but only if you know which machine is covered, for what, and until when. A practical guide to running AMCs without leaks.
When a customer's machine stops, every hour counts. Here is how to log, prioritise, assign and close breakdown calls within SLA, and stop the same calls coming back.

A breakdown call is the moment your customer judges your company. Their machine, analyser or plant has stopped, their own work is held up and they want to know one thing: when will your engineer be there? In many Indian service organisations, the answer depends on who picked up the phone, whether they wrote it down and which engineer happened to be free. Strong breakdown call management replaces that luck with a process: every call logged, prioritised, assigned, tracked against its SLA and closed with a report, so customers get a dependable response and managers can see problems before customers complain.
Most service heads will recognise these failure points:
Each of these can be fixed with clear rules and a system that applies them consistently.
The first rule of breakdown call management is simple: if it is not logged, it does not exist. Customers will reach you through several channels, and all of them must lead to one call record.
At logging, capture the customer, site, equipment serial number, the problem as described, a contact person and how the equipment is affected (fully down, partly working, or a warning). The serial number is what lets the desk pull up the installation date, warranty or contract status and past service history straight away.
Not every breakdown is equally urgent. A short, written priority matrix keeps decisions consistent across the desk.
| Priority | Typical situation | Example commitment |
|---|---|---|
| Critical | Equipment fully down, customer operations stopped or patient care affected | Fastest response in your contract terms |
| High | Equipment working with major limitation or frequent failure | Response within the same or next working day |
| Normal | Minor fault, workaround available | Scheduled visit within the agreed window |
| Low | Query, cosmetic issue or advice | Phone support or next planned visit |
Before sending anyone, try a short remote diagnosis. A few questions or a guided reset can solve a share of calls and tells the engineer which parts to carry for the rest.
An SLA has two clocks: response time (how soon an engineer reaches the site or starts work) and resolution time (how soon the equipment is working again). Both should be defined per priority and per contract type, because a customer on a comprehensive AMC is usually promised more than a customer paying per visit. Our guide to AMC management covers how to set those contract terms.
Decide in advance how you treat working hours, holidays, waiting time for customer access and parts on order, so the SLA clock is fair to both sides and nobody argues about it later.
Assignment should balance three things: distance, skill and workload. The nearest engineer is often the right choice for a critical call, but only if they are trained on that equipment and not halfway through another urgent job. A supervisor with a live view of where engineers are and how many open calls each one has can make this decision in a minute rather than after a round of phone calls.
Once assigned, the engineer should receive the full call on mobile: customer, site, contact, equipment history and the problem description. The customer should be told who is coming and roughly when.
Escalation that happens after a breach is just reporting. Useful escalation happens while there is still time to act. Set escalation points as a share of the SLA time elapsed, for example a warning to the supervisor partway through and an alert to the service head nearer the deadline. The exact points are your choice; the principle is to give someone with authority enough time to reassign the call, send a senior engineer or arrange a part.
Unassigned calls deserve special attention. A call sitting without an owner is the most likely to breach, so the supervisor’s view should highlight them at the top.
Many repeat visits happen because the engineer did not have the part. Reduce them by:
Close every call with a service report: the fault found, the work done, parts used, time spent and any pending action, signed by the customer on the engineer’s phone. The signed report is the proof of resolution, the basis for any charges and the record the next engineer will read.
Once calls are recorded consistently, patterns appear. Review them monthly:
Ask engineers to record a cause code, not just the action taken. A simple, short list of cause codes is enough to make this analysis possible.
In Effezient Field Service, service calls are created, assigned and tracked with full history and warranty data. Customers can raise tickets in their own app and follow them to resolution, while engineers and managers have apps of their own. The supervisor console shows workload, SLA status and escalations across multiple service centres, unassigned calls are highlighted, and live location shows which engineer is nearest.
Calls at risk are calculated from SLA progress and escalated in time. Replacements, charges, collections and deposits are tracked in the call lifecycle, and engineers close calls with digital reports carrying notes and the customer’s signature. Serial numbers from order management carry through to every service call, which is especially useful for medical diagnostics and device companies.
Response time measures how quickly an engineer attends to the call, on site or remotely. Resolution time measures how quickly the equipment is working again. Customers care about both, so define and track both.
Yes. A customer app or portal means calls are logged accurately, with no dependence on someone answering the phone, and customers can check progress without calling repeatedly.
Record a cause code and parts used on every call, review repeat calls on the same serial number every month, and fix the underlying cause, whether that is a part, an installation issue, operator training or the PM schedule.
No. Even a team of a few engineers benefits from logging every call, setting priorities and tracking SLAs. The habits matter more than the size of the team.
