AMC pricing transparency — why 6-10% of installed value is the right band

AMC pricing is the most opaque line in a premium integration scope. The contract sits at the bottom of the BOQ, often added late in the negotiation, and its price is rarely audited line-by-line — the buyer either accepts the integrator's standard percentage or pushes for a discount without examining what the percentage actually buys. Six months later, when a controller fails outside the response SLA or a spare is not on hand, the conversation reopens at a much worse moment.

Below is what we charge for AMC, why the percentage band is where it is, and what specifically gets quietly excluded when an integrator offers an AMC at half the rate of the market.

## Why 6-10% — four cost drivers built up

An AMC on a premium integrated system has four cost drivers, each consuming a percentage of installed value annually. The drivers compound to 6-10% of installed value for a serious AMC programme; integrators who price below 4% are almost always running at zero margin or have silently excluded at least one driver.

### Cost driver 1 — preventive visits (~1.5-2.5%)

Quarterly to semi-annual preventive visits, with a written checklist, calibration checks, firmware audit, configuration backup, and a deliverable visit report. The labour cost is straightforward — engineering days, travel, on-site documentation. For a 2,800-sq-ft villa with Rako, multi-room audio, CCTV and access control, this is two engineers for one day quarterly — 8 engineering-days per year. At ~₹6,000 fully-loaded engineer day-rate, this line alone is ₹48,000 — roughly 1.5% of a ₹32 L installed value. Larger systems with more disciplines and more sites scale up; smaller systems with fewer visits scale down.

### Cost driver 2 — response SLA capacity (~1.0-1.5%)

An SLA that promises 24-hour response on standard tickets and 4-hour response on critical tickets is not free — it requires the integrator to hold engineering capacity in reserve, ready to dispatch. The cost is the engineering bench's idle hours, allocated across the AMC portfolio. For our standard Silver tier (24h standard, 8h critical, on-call extended hours), this allocates roughly 0.8-1.2 engineering-days per AMC per year of standby capacity. At our day-rate that is another ₹40-65k per ₹32 L installed value — roughly 1.0-1.5%.

### Cost driver 3 — parts pool and obsolescence reserve (~1.5-2.5%)

This is the line most commonly excluded by cheap AMC offers. A serious parts pool holds active spares against every controller, every PSU, every panel and every camera class deployed at the AMC customer's site — typically 5-8% of installed device count as ready inventory at our Lachit Nagar office. The pool also carries an obsolescence reserve: a sinking fund against the inevitable replacement of devices whose original manufacturer has discontinued support. On a 7-year average system life, the obsolescence reserve runs at ~1.5-2.5% of installed value per year. AMCs that exclude the parts pool send the engineer on site with no spare; the site visit becomes a diagnosis, and the actual fix waits 2-4 weeks for parts to ship.

### Cost driver 4 — configuration discipline and lifecycle planning (~1.0-1.5%)

The configuration baseline (every controller's programme, every device's firmware version, every patch panel's port assignment) needs to be retained offline, version-controlled and accessible to the engineer dispatched on a ticket. The discipline costs labour — configuration backups after every change, documented version control, retention against device replacement. The lifecycle planning layer maps each device's end-of-support against the building's refresh cycle and flags the year-three pre-emptive replacements before they fail. This is the line that separates a serious AMC from a reactive maintenance contract.

## What buyers most commonly get when an AMC is priced below 4%

Three patterns recur. First, the parts pool is excluded entirely — any replacement device is billed separately at list price plus markup, with shipping time and customs delays as additional risk. Second, the SLA is published but not capacity-backed — the integrator promises 24-hour response but holds no idle engineering, so the response actually happens 'next available' which on a busy month is 4-7 days. Third, the configuration baseline is not retained — every change is logged on the engineer's machine, and any device replacement is a re-programme rather than a restore.

Each of these surfaces as a real cost six months later, but it surfaces as an emergency call rather than as a contract dispute — and the building's operations team eats the cost out of a different budget line.

## The right question to ask an AMC quoter

Three questions separate a serious AMC from a thin one. First: *what specifically is on the parts pool list, and where are those spares held physically?* Ask for the actual SKU list and the address of the warehouse. Second: *what is the SLA capacity backing — how many engineers are on call for the AMC portfolio at any moment?* Ask for the engineering-bench size and the ratio of bench-engineers to active AMC contracts. Third: *show me the configuration backup discipline.* Ask for the version-control system, the retention policy, and the last backup date for an existing AMC customer (anonymised).

An integrator who answers all three crisply is offering a serious AMC. An integrator who hedges on any of the three is offering a contract that will reveal its exclusions six months in.

## Our AMC tier structure

We publish four tiers — Bronze (standard preventive, 48h response, parts-on-quote), Silver (Bronze plus 24h response, 36-month spares pool), Gold (Silver plus 8h response, full obsolescence reserve, quarterly executive review), and Mission-Critical (24/7 on-call, 4h response, on-site stocked spares, configuration discipline at SOC2-class). The four tiers price at 4.5% / 6.5% / 8% / 10-12% of installed value respectively, with Silver and Gold being the most common selections on premium residential and commercial work.

The tier choice is not a status decision. It is an operations decision — Bronze suits buildings where downtime is irritating but not consequential, Mission-Critical suits hospitals and broadcast facilities where downtime is unacceptable. Most premium residential lands at Silver; most commercial integrated estates land at Gold.
