Two businesses call us in the same week. Both have about 80 employees, both are growing, both are frustrated with IT. One should buy fully managed services. The other should absolutely not — co-managed is the right answer. The difference between them comes down to a handful of questions.
If you're weighing the two models, here's the decision framework we actually use — including the two wrong choices we see Houston businesses make over and over.
The thirty-second recap
Fully managed IT: we are your IT department. Helpdesk, monitoring, security, strategy — everything, end to end, for a flat monthly fee. Built for businesses with no internal IT staff.
Co-managed IT: we partner with the IT staff you already have. Responsibilities are split under a written agreement — typically we take 24/7 monitoring, patching, security operations, and overflow, while your team keeps strategy, users, and the applications they know best. (New to the model? Start with our plain-English guide to co-managed IT.)
The five questions that decide it
1. Do you have internal IT staff worth building around?
This is the threshold question. No internal IT — or one reluctant “accidental IT person” who'd rather be doing their real job — points to fully managed. One or more actual IT professionals who know your business points to co-managed. The most expensive mistake in this decision is pretending an office manager with admin rights is an IT department.
2. Who should own IT strategy?
If you want a partner to own the roadmap, budget recommendations, and vendor decisions, that's fully managed with strategic reviews built in. If you have an IT manager who should own strategy — and just needs the operational load lifted so they can actually do it — that's the textbook co-managed case.
3. What happens at 2 a.m.?
Both models solve after-hours coverage. The question is what happens the next morning. In fully managed, our team handles the incident and the follow-up. In co-managed, your IT lead walks in to a resolved ticket and a clear log of what we did — instead of a voicemail and a fire.
4. Do you need skills nobody on staff has?
Security operations, cloud architecture, compliance evidence for auditors and cyber-insurance carriers. If the answer is “we need that, but can't hire it” — co-managed gets you the specialist bench while your generalists stay focused. If the answer is “we have nobody for any of this,” fully managed covers the whole surface.
5. How do you want the budget shaped?
Both are flat monthly fees. Fully managed scales mostly with headcount and devices. Co-managed scales with the responsibility split — you're buying coverage for specific functions, which usually makes it the smaller number when you already pay IT salaries. Either way, the unpredictable-repair-bill model is the one to leave behind.
Side by side
Your IT staff: fully managed — none required; co-managed — one to five people, and they stay central.
Who owns strategy: fully managed — provider recommends, you decide; co-managed — your IT lead, with our input.
Who talks to your users: fully managed — our helpdesk; co-managed — usually your team, with our overflow.
Tooling: identical — both get the full enterprise stack: monitoring, EDR, patching, backup.
Typical buyer: fully managed — 10–100 employees, no IT staff; co-managed — 25–250+ employees, IT team of 1–5.
Contract: both month-to-month with us. If a provider needs a three-year term to keep you, ask why.
The two expensive wrong choices
Wrong choice #1: buying fully managed when you have a good IT team. It happens when leadership is frustrated and wants the problem to just go away. The result: a demoralized IT staff working around the provider, two sources of truth, and quiet sabotage of the arrangement from people who feel replaced. If your IT people are good, build around them — don't pave over them.
Wrong choice #2: hiring another tech when the gap is coverage, not headcount. A second sysadmin gets you 40 more hours of the same generalist skills — for six figures fully loaded, after months of recruiting. If the actual gaps are after-hours coverage, security operations, and project capacity, a co-managed agreement fills all three for a fraction of the cost, starting in weeks instead of months. (We'll publish the full Houston salary math in a couple of weeks — the numbers are starker than most owners expect.)
Can you switch models later?
Yes, and businesses do — in both directions. A company hires its first real IT manager and steps down from fully managed to co-managed. An IT director retires and the company steps up to fully managed rather than replacing him. Because our agreements are month-to-month and the tooling is identical in both models, the switch is a conversation, not a migration.
That's also the honest answer to “what if we're not sure?” — pick the model that fits today. Switching costs you a meeting.
Frequently asked questions
Is co-managed cheaper than fully managed?
Usually, because you're buying a subset of functions — but you're also still paying IT salaries, so the total spend depends on your team. The right comparison is co-managed plus current payroll versus fully managed plus the hiring you'd otherwise need.
Can we co-manage with a one-person IT department?
Absolutely — solo IT managers are some of our happiest co-managed clients. They gain a bench, an escalation path, and the ability to take a vacation without their phone on the nightstand.
What if our IT person is the problem?
Then neither model fixes it, and you have a management decision to make first. We're happy to give an honest outside read of your environment as part of a discovery call — sometimes the answer is coaching and support, sometimes it isn't. We won't pretend a service contract solves a people problem.
The bottom line
The decision is simpler than the industry makes it sound: good internal IT staff → co-managed. No internal IT staff → fully managed. Everything else is detail you can adjust later, month to month.
