IT support quotes throw these four terms around as if everyone agrees what they mean – then the contract turns out to cover something narrower than you assumed. This guide defines each mode, what it should cost, and how to pick the mix your business actually needs, without paying for cover you will never use.
Onsite IT support: when hands must touch hardware
Onsite support is a technician at your premises. It is the right – and only – answer when the problem is physical: swapping a failed drive or PSU, installing and cabling new workstations, racking a server or NAS, fixing Wi-Fi dead zones, setting up meeting-room AV, or recovering a network after a switch failure. It is also how offices get moved and new offices stood up – our office IT setup checklist is essentially a list of onsite work. The trade-off is time and cost: every visit carries travel, and in ad-hoc mode you are paying per trip.
Remote IT support: what gets fixed without a visit
Remote IT support resolves issues over a secure remote-access connection: password resets, software errors, email and Microsoft 365 problems, printer queues, slow PCs, permissions, patching and updates. In our experience running support desks, the large majority of everyday tickets close remotely – which is why response is measured in minutes, not travel time. Modern remote monitoring (RMM) agents shift this further: patches roll out and disks get health-checked before anyone raises a ticket at all. The rule of thumb: if the fix happens on a screen, it should be remote; if it happens with a screwdriver or a cable, it is onsite.
| Factor | Onsite | Remote |
|---|---|---|
| Best for | Hardware, cabling, new setups, Wi-Fi/AV | Software, accounts, email, updates |
| Speed | Travel + scheduling window | Minutes, on connection |
| Cost shape | Per visit (ad-hoc) or scheduled | Included in managed plans |
| Share of typical tickets | The minority | The large majority |
24×7 IT support: who actually needs round-the-clock cover
True 24×7 IT support means staffed cover through nights, weekends and public holidays – and it costs accordingly, because someone is awake for you at 3am. It earns its price when downtime at 3am costs real money: shift operations, logistics and F&B groups, e-commerce, regulated firms with uptime obligations, or teams serving overseas customers across time zones. A standard office that works 9-6 rarely needs it. The honest middle path most SMEs choose: business-hours support with monitored alerting and an on-call escalation for genuine emergencies – you pay for the safety net, not for a fully staffed night desk.
Emergency IT support: what counts as an emergency
Emergency IT support is the escalation lane, and a good contract defines it before you need it. Emergencies: the server or network is down for everyone, ransomware or a suspected breach, email dead company-wide, the point-of-sale offline during trading hours. Not emergencies: one laptop misbehaving, a printer queue, a password reset – those are normal tickets. Two SLA numbers matter and they are different things: response time (how fast a human engages) and resolution target (how fast it is fixed). Ask for both in writing, per severity level – a “15-minute response” that leads to a next-day fix is marketing, not cover.
How the models are priced
Ad-hoc onsite visits in Singapore typically run in the S$80-S$150+ range per trip before parts, which adds up fast once visits become regular. Managed IT support flips the model: a fixed monthly fee per user or device covers remote support, monitoring and agreed onsite time, with emergency response defined in the SLA. The crossover point arrives earlier than most owners expect – our IT support cost guide puts real numbers on both models, and the managed vs break-fix comparison explains why per-incident billing quietly rewards your provider for your problems.
Which mix does your business need?
- Count the cost of an hour down – for the whole team, not one PC. This sets how much cover is rational.
- Default to remote-first – it resolves the majority of issues fastest and cheapest.
- Schedule onsite, don’t ration it – a regular visit cadence for the physical work beats emergency-only trips.
- Buy the emergency lane, not the night desk – defined severity levels with response and resolution targets; add true 24×7 only if downtime at night costs real money.
- Put it all in the SLA – modes, hours, response and resolution per severity, and what counts as an emergency.
Frequently asked questions
What is onsite IT support?
Onsite IT support is a technician physically attending your premises to resolve issues that need hands on hardware – failed components, new workstation and server installations, network cabling, Wi-Fi coverage, meeting-room AV and office moves. It complements remote support, which handles software and account issues over a secure connection without a visit.
What is the difference between onsite and remote IT support?
Where the work happens. Remote support fixes screen-level problems – software, email, accounts, updates – over a secure connection within minutes. Onsite support handles physical work: hardware, cabling, installations. In practice the large majority of everyday tickets resolve remotely, so modern contracts are remote-first with onsite visits scheduled for the physical minority.
Do small businesses need 24/7 IT support?
Usually not in the fully-staffed sense. A 9-6 office needs business-hours support plus monitored alerting and an on-call emergency path – so a dead server on Sunday night is being worked before Monday standup. True 24×7 staffing is worth paying for when night-time downtime costs real revenue: shift operations, e-commerce, logistics, or regulated uptime obligations.
How fast should IT support respond?
Judge two numbers separately: response time (a human engages) and resolution target (it is fixed), defined per severity. Reasonable managed-support benchmarks: emergencies like a server down get response within 15-60 minutes; normal tickets same or next business day. Any SLA that quotes only response time and stays silent on resolution deserves questions.
How much does an onsite IT visit cost in Singapore?
Ad-hoc onsite visits typically run around S$80-S$150 or more per trip before parts and after-hours loading. Managed support plans usually fold agreed onsite time into a fixed monthly per-user fee, which becomes cheaper than per-visit billing once you need more than occasional trips – the crossover math is in our IT support cost guide.
What should I do in an IT emergency?
Use the escalation path in your support agreement – the emergency number, not the normal ticket queue – and describe the impact (how many people, which systems, since when), which sets the severity level. For suspected ransomware, disconnect affected machines from the network but do not switch them off or pay anything before your provider engages. If your current contract has no written emergency path, that is the gap to fix this week.
