Glossary / Break-fix
Break-fix
A reactive IT service model where a technician is called (and billed) only after something breaks, in contrast to managed services' flat-fee, proactive-monitoring model.
Break-fix is the older model IT support ran on before managed services became standard: a client calls when a server goes down or a laptop won't boot, a technician is dispatched or remotes in, the problem gets fixed, and an invoice goes out for the time and materials. There's no ongoing monitoring and no proactive maintenance — the relationship activates only when something is already broken.
The economics are the key difference from managed services. A break-fix provider is paid more when things fail more often and take longer to fix — the incentive doesn't reward prevention. An MSP paid a flat recurring fee per device or user has the opposite incentive: fewer incidents and faster fixes both improve margin, which is why proactive monitoring, patching, and maintenance became central to the managed model rather than optional extras.
Break-fix hasn't disappeared — it still fits specific situations well, like a business with very simple, low-risk IT needs, or an MSP relationship that layers project work on top of a base managed contract. But for anything where downtime or a breach carries real cost, the misaligned incentive of pure break-fix is the main reason the industry shifted toward recurring managed contracts.
How Nexus handles this
Nexus is built for the managed-services side of that divide — proactive monitoring, patching, and ticketing live in the same platform an MSP runs its recurring contracts on, rather than tooling built around one-off, reactive dispatches.
More terms
MSP (Managed Service Provider)
A company that remotely manages a client's IT infrastructure and end-user systems on an ongoing, proactive basis — usually a flat-fee contract, not break-fix billing.
RMM (Remote Monitoring and Management)
Software that lets an MSP monitor device health and perform remote management tasks — patching, scripting, remote control — across every client site from one console.
PSA (Professional Services Automation)
Software that runs the business side of MSP operations — ticketing, SLAs, billing, contracts, and client records — the system of record most MSP work flows through.
