Hire in-house, or outsource?
The honest comparison, including the cases where hiring is clearly the better answer.
Hiring gives you permanent capability and full control, at the cost of three to six months to recruit and the overhead of employing people. Outsourcing starts in weeks and scales down when the work ends. Most companies eventually need both.

Short answer
Hire for anything core, permanent and central to your business. Outsource for a defined project, a temporary peak, or a skill you need occasionally. Outsourcing something core and ongoing is usually an expensive way to avoid recruiting.
The comparison people make is cost per hour. The comparison that matters is what happens when the work changes.
An outsourced developer looks more expensive per hour than a salary divided by working days. That comparison is almost always wrong, because it counts the salary and nothing else — not recruitment fees, equipment, taxes, benefits, holiday, the two to three months before someone is productive, or the cost of a hire that does not work out.
But the honest case for hiring is not cost. It is continuity and investment. Someone employed by you accumulates knowledge of your product over years, sits in the room when decisions are made, and cares about the codebase in a way that is genuinely harder to buy.
The real decision is about the shape of the work. Permanent, core and central work belongs in-house — outsourcing it puts your least replaceable knowledge outside the company and creates a dependency that is expensive to unwind. Defined projects, temporary peaks and occasional specialisms are what outsourcing is actually good at.
Most companies end up doing both, and the sensible arrangement is a small permanent team owning the core with outsourced capacity around it. The arrangement that goes wrong is the inverse: outsourcing the core and hiring for the periphery.
Side by side.
| In-house | Outsourced | |
|---|---|---|
| Time to start | 3–6 months to hire | 2–4 weeks |
| Cost | Salary, taxes, equipment, benefits | One monthly invoice |
| If the work ends | Redundancy process | Stop with notice |
| If it is not working out | Slow and difficult | Replace, or stop |
| Knowledge retention | Stays — while they stay | Needs documenting deliberately |
| Holiday and sickness | Your problem | Covered |
| Cultural fit and loyalty | Stronger | Weaker, honestly |
| Right for | Core, permanent, central | Projects, peaks, occasional skills |
Hire in-house when
- The work is core and will not end
- Deep product knowledge compounds over years
- You need someone in the room for decisions daily
- You can wait three to six months and afford the overhead
Outsource when
- The work has a defined end, or is a temporary peak
- You need a skill occasionally rather than constantly
- Hiring locally is slow, expensive or genuinely difficult
- You want to move now rather than in six months
What people get wrong.
Comparing hourly rate to salary alone
Recruitment, equipment, taxes, benefits, holiday, ramp-up time and bad-hire risk are all real costs that never appear in the comparison.
Outsourcing the core to save money
It works until you want to change direction quickly, or the supplier relationship ends. Your most important knowledge should not sit outside the company.
Assuming knowledge transfers automatically
It does not. Documentation written throughout, code in your repository from day one, and a real handover — none of that happens unless it is designed in.
Hiring for a temporary peak
Three to six months to recruit, then the peak passes and you are overstaffed with a redundancy process ahead. This is precisely what outsourcing is for.
Four questions that settle it.
The first one resolves most cases on its own.
Will this work still exist in two years?
If yes and it is central to the business, hire. If it has a defined end, outsource — you should not be running a redundancy process for a project.
Can you wait three to six months to start?
That is a realistic hiring timeline including notice periods. If the answer is no, outsourcing is the only route that starts in weeks.
Do you need this skill constantly or occasionally?
A security specialist you need twice a year should not be an employee. A product engineer you need every day probably should be.
Could you describe how you would leave your supplier?
Ask them directly. If they cannot answer clearly, your knowledge is not safe and the cost comparison is irrelevant.
What people ask next.
Usually per hour, and not always overall. What is often missed on the in-house side is the full cost — recruitment fees, equipment, taxes, benefits, holiday, the months before someone is productive, and the risk of a bad hire. What is missed on the outsourced side is the coordination overhead and the knowledge that leaves when the engagement ends. Compare fully or the comparison misleads you.
There is no inherent one, in either direction. There are excellent outsourced teams and poor in-house ones, and vice versa. What genuinely differs is incentive and continuity: an employee is invested in the codebase for years, while an outsourced team is invested in the engagement. That is manageable with the right arrangement and worth being clear-eyed about.
It leaves unless you make it stay, and this is the real risk rather than cost. Documentation written throughout rather than in the final week, code in your repository from day one, and a handover with whoever takes over. If a supplier cannot describe how you would leave them, that is the answer to whether your knowledge is safe.
Most companies eventually do, and it is usually the right shape. A small permanent team owning the core product, with outsourced capacity for peaks, specialist work or a second workstream. What does not work well is outsourcing the core and hiring for the periphery — that puts your least replaceable knowledge outside the company.
