Sooner or later every growing company asks the same question: should we outsource IT, or keep it in-house? It usually comes up at a particular moment. The person who looks after IT is overloaded or leaving, a new office opens, or a backup or security worry has been postponed once too often.
No answer is right for every company. This guide gives you a way to decide: what each option involves, a fair comparison that includes the cases where in-house is the better choice, the costs people tend to forget, the risks to check whichever way you go, and a checklist to work through with your colleagues. BlueNova IT is an IT provider, so you should weigh this guide with that in mind. If you already know you want to hand work over and need to define it, our IT outsourcing page describes how we agree scope in writing.
The three options in plain terms
- In-house IT. You employ the people who run IT: one generalist, a small team or a full department. They work for you, know your business and answer directly to your management.
- Outsourced IT. An external provider takes responsibility for defined IT work under a written agreement, from everyday user support and maintenance to a single project. Our managed IT services are one form of this.
- Co-managed IT. Your own IT people and an external team share the work, with each task assigned to one side. We offer co-managed IT alongside your own team. We describe it in our guide to co-managed IT vs managed IT vs break-fix.
Outsourcing is not all or nothing. Handing over the whole IT department is one end of a range; many companies keep the decisions in-house and outsource only some tasks, and the split changes as the company grows.
In-house, outsourced and co-managed side by side
| What to compare | In-house | Outsourced | Co-managed |
|---|---|---|---|
| Day-to-day accountability | Your employees, managed by you | The provider, for the agreed scope | Shared, task by task, in writing |
| Knowledge of your business | Deepest, built up over years | Starts shallow and grows with time and documentation | Strong on your side, topped up from outside |
| Cover for absence or departure | Depends on team size; one person is a single point of failure | Often a team, within the agreed hours | Your team plus an external backup |
| Range of skills | Limited to the people you hire | Wider, used as needed | Your team’s skills plus specialists for gaps |
| Time to start | Recruitment and onboarding take time | Can be quicker once scope and access are agreed | Quicker than hiring, but needs a clear split first |
| Cost shape | Salaries, employment costs, training and tools; mostly fixed | Fees tied to the agreed scope, which can follow users and devices | Internal salaries plus a smaller external scope |
| Control and access | Full day-to-day control | You keep ownership but rely on the provider’s discipline and records | You stay in charge; access agreed in writing |
| Flexibility when needs change | Changes mean hiring, training or reorganising | Scope can be widened or narrowed at a review | The mix can be shifted either way |
| Main risk | Dependence on one or two people | Vague scope, weak handover, distance from your business | An unclear split of responsibility |
Read the table as tendencies, not rules: a particular team or provider can differ, and none of the three wins on every row.
When in-house is the right answer
Outsourcing is not always the better route. In-house IT tends to be the stronger choice when:
- IT is part of your product or operations. If your staff build, tune or run systems specific to your business all day, outside people will always be one step removed.
- There is enough steady work for dedicated people. When requests, projects and maintenance regularly fill a full working week, a salaried person can give better value than buying the same hours from outside.
- Your rules require it. Some contracts, customers or regulated activities restrict who may touch certain systems or data. Check the wording before assuming either way.
- You need hands on the premises every day. A single site with many physical devices and constant hands-on needs favours someone who works there, although a provider’s on-site visits can cover part of it.
- You already have a capable, stable team. If it copes, documents its work and has cover for absences, changing the arrangement for its own sake adds risk.
Even then, an outside party can help occasionally with a project, a security review or holiday cover. That is where the co-managed model fits.
Should you outsource IT? Signs that it fits
For a small business or a midsize company, outsourcing tends to fit better when:
- Nobody owns IT. It falls to whoever is most technical, next to their real job.
- Knowledge sits with one person. If that person leaves or is ill, nobody knows where things are.
- You operate in several countries or offices. You want one support route in the languages your teams use; ours are English and Spanish.
- The workload is uneven. Projects create peaks and quiet weeks follow, so a full-time hire would be hard to keep busy.
- Maintenance keeps slipping. Updates, backup checks and account clean-ups happen only after something breaks.
- You need a skill you rarely use. A security review or a migration does not justify a permanent role.
If you recognise only one or two of these, the answer may be a smaller step than full outsourcing, such as covering holidays or one specialist task.
What the cost comparison should include
We do not quote prices here, because they depend on users, devices, locations, hours and scope, and a figure without those would mislead. What you can do is make the comparison complete, because the two sides are usually priced on different bases.
Costs people forget on the in-house side
- Recruitment time, and the weeks a position stays empty.
- Employment costs beyond the salary.
- Training to keep skills current, and the tools and licences the person needs.
- Cover for holidays and sickness.
- Management time spent supervising and setting priorities.
Costs people forget on the outsourced side
- Your own time to raise, approve and review requests.
- The effort of onboarding and handover at the start.
- Work outside the agreed scope, which may be charged separately.
- The effort of switching later if the relationship ends.
Ask every candidate, internal or external, to price the same written list of tasks, not a general "IT support" line. Then set the result against what an hour without email, files or your main business system costs you, because that figure often matters more than the difference between the options.
Risks to check whichever way you go
- Single points of failure. In-house, it is one person. Outsourced, it can be one account manager, one tool or one set of credentials. Ask who covers each.
- Ownership and access. Accounts, licences, domains and data should be in your company’s name, and you should be able to see who holds administrator rights and remove them.
- Supplier oversight. A provider with access to your systems becomes part of your supply chain. The UK National Cyber Security Centre’s guidance on establishing control of your supply chain, for example, suggests setting minimum security requirements for suppliers and watching for over-reliance on a single one.
- Personal data. If a provider handles personal data on your behalf, the European Data Protection Board’s guidelines on controllers and processors state that the processing must be governed by a written, binding contract. Your legal adviser can confirm what applies to you.
- Handover and exit. Whoever runs IT, the documentation should let someone else take over: account list, network overview, backup arrangements, supplier contacts. Ask any provider how handover works on the first day and on the last. If you are switching, changing IT provider and what to collect first sets out the order.
A decision checklist
Work through these questions with the people who raise IT requests as well as with management. Write the answers down instead of discussing them in general terms.
- Is there a named person who owns IT today, with time for prevention as well as requests?
- If that person were away for two weeks, who would act, and could they find what they need?
- Does the workload fill a full working week for one or more people, month after month?
- Which tasks are repeatable and can be documented, and which depend on knowing your business closely?
- Do you need support in more than one language, time zone or site?
- Do any contracts, customers or regulations limit who may access certain systems or data?
- Which skills do you need only occasionally, such as security, cloud or networking?
- Are accounts, licences and administrator access documented and held in your company’s name?
- How much management time can you realistically spend supervising either option?
- How quickly could you reverse the decision if it did not work?
Reading the answers: a named owner with real cover (1, 2), steady full-time work (3) and rules that restrict access (6) point towards in-house. No owner and no cover point towards outsourcing. A capable person who is overloaded or lacks occasional specialist skills (4, 7) points towards co-managed. The checklist informs the decision; it does not make it.
How to test the choice before committing
- List the work. Use your request history, or note every IT request for two weeks, with who handled it and how long it took.
- Sort it into three piles. Keep, hand over, and share. Decisions and anything tied to how your business works usually go in the first pile.
- Ask for the scope in writing. From any provider, ask what is included and excluded, who holds administrator access, which hours and languages apply, and how handover and exit work. See what to put in writing in an outsourcing agreement for the points to settle.
- Start narrow and review. Agree a limited first scope and a review date, then widen or narrow it based on what you see.
