The onsite IT support budget trajectory.
Why onsite IT support becomes the standout line item in CFO-reviewed IT budgets between 2026 and 2032 — modelled for Fortune 500 enterprises, cited from Gartner, MetricNet, and IDC.
For a Fortune 500 enterprise IT budget today, onsite IT support consumes around 8% of operational IT cost. As agentic AI compounds savings across the rest of the stack — ITSM workflows, infrastructure operations, software deployment, service desk Tier 1 — onsite support's share will rise to 12–15% by 2032.
The line doesn't rise because onsite gets more expensive. It rises because every other layer of IT gets cheaper while this one stays the same. AI cannot reach through a screen.
For an MSP or in-house IT operation, this trajectory makes onsite support the most visible cost-to-serve problem on the CFO's spreadsheet from 2027 onwards — and the one without a path to automation, unless the AI–physical bridge is solved.
What happens to onsite support as everything else gets cheaper?
Every IT leader is being asked the same question this year: how do we make AI translate into real cost reduction? The answer for most of the IT stack is being scrambled together — ServiceNow Now Assist, Microsoft Copilot for Service, agentic ITSM, network AIOps, software-deployment automation, Tier 1 chatbots. All of these compound. Each AI investment in 2026 pulls down operational cost in 2027, 2028, 2029.
But onsite physical IT support — laptop handovers, peripheral swaps, broken-device exchanges, new-starter kit-out, engineer truck-rolls — hasn't moved in 35 years. The moment a workflow needs a human to be physically present, AI cannot reach.
The question this note answers: if AI delivers on Gartner's forecasts for the rest of the stack, what happens to onsite IT support as a share of the operational IT budget? And at what point does it become the line item that CFOs cannot ignore?
Modelled for a representative Fortune 500 enterprise.
The trajectory in the full research note is calibrated against a representative Velocity Ideal Customer Profile — Fortune 500 enterprise, ServiceNow-standardised, multi-site, regulated-industry footprint. The percentages travel reasonably well across the Fortune 500 / Fortune 1000 range.
| Parameter | Value |
|---|---|
| Industry | Fortune 500 enterprise (pharma · aerospace · energy · financial services · higher ed) |
| Revenue | $10B |
| Employees | 30,000 |
| Sites | 25+ operational sites, multi-region |
| IT platform | ServiceNow-standardised |
| IT spend (% revenue) | ~3% = $300M total IT budget |
| Operational IT cost | ~60% of total = $180M (excludes new investments, AI infrastructure capex) |
| Onsite IT support today | $15M = 8.3% of operational IT cost |
