Managed IT AMC vs break-fix support.

Break-fix and AMC (annual maintenance contract) support are often compared purely on price, but the more important difference is what each one actually optimises for.

Break-fix: pay when something breaks

Break-fix support means calling for help only when an issue occurs, and paying per visit or per incident. It can suit a very small setup with few devices and low complexity, where the cost of occasional downtime is genuinely low. Its weakness is that nothing is preventing the next failure — maintenance, monitoring and lifecycle planning are not part of the arrangement.

AMC: pay for prevention and predictability

An AMC covers a defined scope — devices, response times, preventive maintenance, and often monitoring — for a predictable recurring cost. The value is not just faster response when something breaks; it is fewer things breaking in the first place, because patching, health checks and asset lifecycle are managed proactively.

What actually decides which fits

• Device and user count. More devices generally means more value from preventive maintenance and monitoring.
• Cost of downtime. If an outage stops revenue-generating work, the predictability of AMC usually outweighs its cost.
• Internal IT capacity. A business with no internal IT resource benefits more from AMC’s defined ownership than one with an in-house administrator handling day-to-day issues.

Neither model is universally correct — the right one depends on how much an hour of downtime actually costs your business, and whether that cost is worth insuring against with a defined support agreement.
