Managed IT vs In-House IT
A balanced way to decide who should run your IT: an external provider, your own staff, or both.
In short
Managed, in-house or co-managed — the short answer
Managed IT means an external provider takes responsibility for agreed IT work under a written scope; in-house IT means employing your own staff; co-managed splits the work between both. None is cheaper or better in every case. The right fit depends on your users, sites and applications, the skills and cover you need, how much onsite work is required and who is accountable when something goes wrong.
- Size the workload first: users, devices, sites, applications and how often things change.
- Weigh skills, leave cover and the risk of relying on one person.
- Compare full cost categories, not just a salary against a monthly fee.
- Larger and co-managed environments need an individually agreed scope.
Workload
Start by sizing the IT workload
Before comparing options, describe what actually needs looking after. The answers shape every option below.
Users and devices
How many people need support, how many laptops and desktops they use, and how many shared or special-purpose devices exist.
Sites
One office, several branches or many people working from home. Each site adds network equipment and potential onsite visits.
Applications
Microsoft 365, accounting or line-of-business software, and who supports each one today — staff, a vendor or nobody in particular.
Rate of change
Frequent joiners and leavers, office moves and new systems all add work that is easy to underestimate.
Onsite needs
How often problems genuinely need someone physically present, such as hardware swaps, cabling or printer faults.
Risk and recovery
What would stop the business if it failed — email, files, a key application — and how it would be recovered.
People
Skills, cover and accountability
IT work spans more skills than one person usually has. Consider each of these honestly.
- Breadth of skills
- Helpdesk, security tooling, Microsoft 365, networks and servers are different specialities. Few individuals cover all of them well.
- Leave and sick cover
- A single in-house person cannot be available every working day. Plan who covers annual leave, illness and resignations.
- Knowledge held by one person
- If passwords and how things are set up live in one person's head, the business carries a risk whichever model it picks.
- Local business knowledge
- Internal staff know your people and processes. A provider needs good documentation and onboarding to build the same picture.
- Accountability
- Decide who answers for outcomes: an employee under a job description, or a provider under a written agreement with defined scope.
- Strategic input
- Budgeting, planning and choosing systems still need a decision-maker inside the business, regardless of who does the technical work.
Responsibility matrix
Who typically does what
A starting point for discussion. In practice, every agreement should define these lines in writing.
| Task | Managed IT | In-house IT | Co-managed |
|---|---|---|---|
| Day-to-day user support | Provider, within agreed scope | Internal staff | Usually the provider, with local escalation |
| Patching and monitoring | Provider, using its tools | Internal staff and tools | Agreed split, often the provider |
| Endpoint security tooling | Provider, on managed devices | Internal staff and purchased tools | Agreed split, written down |
| Microsoft 365 administration | Provider where that module is chosen | Internal staff | Agreed split; shared admin access documented |
| Business application ownership | Software vendor; provider coordinates | Internal staff with vendor | Internal staff with vendor |
| Onsite hardware work | Arranged and charged as needed | Internal staff | Internal staff or arranged provider visits |
| Projects and purchasing | Quoted separately | Internal staff and budget | Agreed per project |
| IT strategy and budget decisions | Business decides, provider advises | Business decides | Business decides |
Decide
Decision checklist
- We know how many users, devices, servers and sites need support.
- We know which applications we rely on and who supports each one.
- We have a plan for leave, illness and staff turnover.
- We know where passwords and admin accounts are held.
- We have listed how often we really need someone on site.
- We have compared full costs, not just a salary against a fee.
- We know who is accountable for security and backup.
- If co-managed, we have a written split of responsibilities.
Cost
Full cost categories to compare
Outsourcing is not automatically cheaper. List every cost on both sides before deciding.
Employing IT staff
Salary, benefits, recruitment, training and the management time spent supervising technical work.
Tools and software
Monitoring, patching, remote-support and security tools that an internal team needs to buy and maintain.
Cover and continuity
Extra people or contractors to cover leave, illness and handovers when staff move on.
Managed service fees
The monthly per-user fee, chosen modules such as Microsoft 365 management or backup, and any minimum monthly charge.
Once-off and variable costs
Onboarding, remediation of inherited problems, projects, onsite visits and travel under a managed agreement.
Costs that exist either way
Microsoft licences, hardware replacement, internet connectivity and specialist application support.

FAQs
Frequently asked questions
Is managed IT cheaper than employing an IT person?
Not always. It depends on how many users and sites you have, the skills you need and how much onsite work is required. Compare the full cost of each option — salary and benefits, tools, training and leave cover on one side; monthly fees, modules, onboarding, onsite work and projects on the other.
Can we keep our IT person and add a managed service?
Yes. In a co-managed arrangement, your internal person keeps the work that needs local knowledge while the provider handles agreed routine tasks, tooling or cover. Write down who does what, who holds admin access and how escalations work.
Who is accountable when IT is co-managed?
Whoever the written split says. Accountability gaps appear when two parties both assume the other is handling something, such as patching servers or checking backups. A responsibility matrix agreed at the start avoids this.
What size business suits SureTel's Managed IT?
SureTel's Managed IT is aimed at Gauteng businesses with roughly 15–50 users. Smaller agreements below the normal R7,500 monthly base minimum need management approval, and larger or co-managed environments are scoped individually.
Do we lose onsite help with a managed service?
Managed IT is usually remote-first, with onsite visits arranged when a problem needs hands on site. With SureTel, onsite work is R450 per hour with a one-hour minimum, plus R4.95 per km return travel, with no separate travel-time charge and no guaranteed arrival time.
What happens when our in-house IT person is on leave?
That is one of the main questions to answer. Options include a second internal person, an agreed external provider for cover, or a co-managed arrangement where routine work continues regardless of who is away.
