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.
The installation is where a sale becomes a working machine at the customer site. Here is how to run installation jobs from sales order to signed handover, warranty and AMC.

For a company that sells machines, analysers, panels or plant equipment, the sale is not complete when the purchase order arrives. It is complete when the equipment is installed, working and accepted by the customer. Yet in many Indian equipment companies, installation runs on phone calls between the sales rep, the dispatch team and an engineer, with the details living in WhatsApp chats and paper job sheets. Good installation management turns that handover into a tracked job with an owner, a date, a checklist and a signed report, and it sets up everything that follows: warranty, preventive maintenance and the annual contract.
Installation sits between two teams that rarely share a system. Sales knows what was promised. Service knows how to install. The gaps appear in between:
The installation job should start from the sales order, not from a phone call. When the order is confirmed, the following should travel with it automatically to the service or projects team:
For simple products, one installation job per order is enough. For larger orders, such as a complete lab setup, a production line or a multi-site rollout, treat the installation as a small project with tasks, dependencies and milestones: civil work, electrical work, delivery, mechanical installation, commissioning, trial run and training. Each task has an owner and nothing starts before it can.
A wasted visit costs a full engineer day plus travel. A site readiness check prevents most of them. Send the customer a short pre-installation checklist when the order is confirmed and get it confirmed before scheduling.
| Check | What to confirm |
|---|---|
| Space and access | Floor space, door width, lift or crane access for the equipment |
| Utilities | Power supply and earthing, water, compressed air, drainage or ventilation as required |
| Civil work | Foundation, platform or mounting ready and cured |
| Environment | Temperature, dust and humidity conditions as per the equipment specification |
| Materials | Equipment delivered, unpacked only in the engineer’s presence if required, consumables available |
| People | Site contact, operators for training and an authorised person to sign the report |
If the site is not ready, record it on the job with the reason.
Scheduling an installation is more than picking a free date. Consider:
Give the engineer everything on mobile before they leave: the order details, site contact, readiness status and the installation checklist for that model.
The serial number is the link between the installation and every service event that follows. Capture it on site, ideally by scanning the barcode, and record it against the customer, the site and the order. If the equipment has major sub-assemblies with their own serial numbers, such as a compressor, a controller or a detector, capture those too.
Once linked, the service desk can see on any future call which unit it is, when it was installed and whether it is under warranty.
Every model should have a standard installation checklist. It keeps quality consistent across engineers and makes training new engineers easier. A typical checklist covers:
The installation report should record the checklist results, serial numbers, any pending points, the engineer’s notes and photos if your process uses them. The customer’s authorised person signs it on the engineer’s phone. Unlike a carbon copy, it reaches the customer and the office immediately.
Decide your policy clearly: does warranty start from invoice date, dispatch date or installation date? Many equipment companies use the installation date, or the earlier of installation and a fixed period after dispatch, so that a delayed installation does not eat into the customer’s warranty unfairly or extend it indefinitely. Whatever the policy, the signed installation report is the evidence for the start date.
Most avoidable service calls come from operators who were never properly trained. Make training a checklist item, note who was trained, and leave a simple operating guide. If the customer’s operators change later, a refresher can be offered as part of an AMC visit.
The day of installation is when the next twelve months of service become predictable. From the installation date and the warranty terms, you already know when the warranty visits and the first preventive maintenance visit are due. Put them on the schedule now, not when the customer calls. Our guide to building a preventive maintenance schedule covers how to set PM frequencies by equipment type.
The installation is also the right moment to start the AMC conversation. The customer has just seen the engineer’s work, and the warranty end date is known. Record it, set a reminder well before expiry and let the sales or service team propose the contract in time.
Effezient connects the sales order, the installation and after-sales service. In order management, every unit is tracked by barcode and serial number from order to dispatch, and serials carry through to warranty and service calls. For larger jobs, Projects & Tasks can create the installation project automatically when an opportunity flagged for a project is won, using templates per division, with task dependencies, milestones and reminders to task owners on mobile.
In Field Service, contracts, SLA terms, installation and parts sit in one place. Engineers close jobs with digital reports that carry notes and the customer’s signature, warranty service calls are generated automatically and tracked to closure, and preventive maintenance visits are scheduled with checklists. Companies in industrial manufacturing and equipment use this to carry each machine from enquiry to installation and AMC.
Sales should own the commitment and the handover; service should own the installation itself. What matters most is that the handover happens in the system, with complete details, as soon as the order is confirmed.
That is a policy decision for your company, set out in your warranty terms. Many equipment companies prefer the installation date because it reflects when the customer actually starts using the equipment. Either way, record the date on the installation report.
Ideally, yes, at least for each product family. A common base checklist with a few model-specific steps is easy to maintain and keeps installations consistent across engineers.
It gives you a clean record of every installed unit, its warranty end date and its service history. That makes it easy to approach customers before warranty expires, and a well-run installation makes them more willing to sign.
