Managed vs Co-Managed IT: Which Fits a Business With One IT Person?
Many small and medium businesses reach the same point. There's one IT person, sometimes an employee who took it on alongside another job, sometimes a capable full-time hire. They're stretched, they can't take a holiday without worrying, and there are projects nobody has time for. The question is whether to hand IT to an outside provider entirely, or bring one in to work alongside the person you have.
What the two models mean
Fully managed IT
An outside provider is your IT department. They handle support for your staff, devices, email and Microsoft 365 or Google Workspace, the network, security, backups and the vendors, and they plan ahead with you. Nobody inside the business needs to be technical.
Co-managed IT
Your IT person stays in charge, and an outside provider backs them up. The split is agreed up front: typically the provider takes projects, specialist work (firewalls, servers, security, migrations), overflow when things get busy, and cover for time off, while your IT person keeps the day-to-day relationship with staff.
A side-by-side view
| Question | Fully managed | Co-managed |
|---|---|---|
| Who staff go to first | The provider | Your IT person |
| Who sets priorities | You and the provider | Your IT person, with the provider |
| Specialist and project work | The provider | Usually the provider |
| Cover for holidays and sickness | Built in | The provider steps in |
| Knowledge of your business | Built up by the provider | Stays with your IT person, shared with the provider |
| Best when | No one inside does IT, or the owner has been doing it after hours | You have someone good who needs backup and depth |
Signs co-managed IT is the better fit
- Your IT person knows the business and the staff trust them. Replacing that would be a loss.
- They're good at the day to day but don't have time, or the specialist skills, for projects like a server replacement, a firewall upgrade or a move to the cloud.
- Everything stops when they're on holiday or off sick.
- They'd value someone to check their thinking before a big change.
Signs fully managed IT is the better fit
- IT is a side job for someone whose real role is elsewhere, and it's eating into that role.
- The owner or office manager is the help desk.
- Nobody is sure what the business owns, which accounts exist, or how the backups work.
- Your IT person is leaving, and you'd rather not rely on one person again.
What to agree before you sign anything
- Who does what. Write the split down: which tasks the provider owns, which stay inside, and how requests are passed between you. Most co-managed arrangements that go wrong had no written split.
- Support hours and response times. Agree them up front in the service agreement, including what happens after hours and in an emergency.
- Access and ownership. Admin accounts and passwords stay in the company's name, in a password manager the business controls. The provider gets its own accounts, not shared logins.
- Documentation. Who writes it, where it lives, and that it belongs to you.
- How you'll pay. A flat monthly fee, hourly, prepaid hours or fixed-price projects. Co-managed arrangements often start with a block of hours and a project or two.
- How you'd leave. A good provider makes it easy: everything is documented and the accounts are already yours.
It doesn't have to be permanent
The two models are a spectrum, not a one-time choice. Plenty of businesses start co-managed while their IT person is there and move to fully managed when that person leaves, or the reverse when they hire. The thing that makes switching painless is the same in both cases: everything written down, and every account in the company's name.
