What Does 24/7 IT Support Cost? Pricing Models and SLAs Explained

"What does it cost?" is the question that opens almost every conversation about IT support. The honest answer: it depends on three parameters that have to be spelled out before anyone quotes a figure. Without them, any price list is fiction.

Three parameters that set the price

Scope — what exactly is covered: servers and network only, or also workstations, printers, low-voltage systems, automation? Response time — one hour, four hours, next business day? Every step down that ladder means genuinely maintained readiness of people and spare parts. Coverage window — 8/5, 12/5 or full 24/7? The difference between "support until 4 p.m." and real round-the-clock readiness is not a surcharge; it is a different way of organising work on the provider's side.

Three pricing models

Monthly flat fee — a fixed charge for a defined scope. Predictable budget, and the provider's incentives point the right way: they earn when nothing breaks, so prevention pays off for them. This is the model for companies where IT is critical.

Hourly billing — you pay for actual interventions. It looks cheap while nothing happens; with a serious failure the bill can exceed a year of flat fees. Sensible only for non-critical infrastructure.

Hybrid — a low retainer for monitoring and readiness plus rates for work outside the package. In practice the most common compromise.

A rule that rarely fails: if a 24/7 offer is suspiciously cheap, someone has not priced in the cost of night shifts — and the first customer with a 2 a.m. failure will find that out.
