Freelancer or In-House Developer: Which Should You Choose
A freelancer suits a one-off or variable need, with no long-term commitment, at a daily rate of 200 to 700€ depending on experience. An in-house employed developer generally costs between 4000 and 7000€ a month including charges depending on seniority, but is worth it once the development need becomes permanent and calls for deep, ongoing product knowledge. The choice mainly depends on how regular and how large the need is, not a default preference for one status over the other.
The real problem: anticipating a workload you don't yet know
The main difficulty with this choice is that it usually comes up before you have a clear picture of how much development is actually needed over time. Hiring a developer in-house too early, while the workload is still irregular, creates a significant fixed cost for an activity that doesn't yet justify it. Conversely, staying indefinitely on freelancers once the need has become permanent and structural for the product can end up costing more and weaken the project's continuity.
The right approach generally consists of observing the real regularity of the need before deciding, rather than acting on an initial gut feeling.
What a freelancer allows
A freelancer offers a flexibility that employment doesn't: you pay for time actually worked, with no commitment to a duration, and you can end the collaboration at the end of a project without a dismissal procedure. The daily rate, between 200 and 350€ for a junior profile and 350 to 700€ for a senior one, remains in absolute terms higher than an equivalent daily salary, but that difference reflects the absence of social charges, paid leave, and any long-term commitment for the hiring company.
This flexibility has a downside: a freelancer may not be immediately available for an urgent matter, and their knowledge of the product stays shallower than an employee who works on it day to day for months or years, at least at the start of the collaboration.
What in-house employment allows
An in-house employed developer generally costs between 4000 and 7000€ a month including charges depending on seniority, a fixed amount regardless of the actual volume of work available each month. In exchange, the company has a dedicated, full-time resource, available as a priority, who builds up over time a detailed knowledge of the product, past technical choices, and business context. This accumulated knowledge has real value for a product that keeps evolving over several years.
The trade-off is the risk of underuse: if the volume of development needed fluctuates significantly, the salary is still owed even during slow periods, unlike a freelancer who is only engaged when the need exists.
The regularity-of-need criterion
The most decisive factor remains how regular the workload is. A company with a constant development need, full-time or close to it, over several consecutive months, generally benefits from hiring in-house: the fixed monthly cost becomes competitive against a freelancer engaged continuously over the same period, and the accumulated product knowledge becomes an asset. A company with a one-off, variable need, or one limited to a few weeks or months a year, benefits from staying with freelancers, paying only for the time actually needed.
The hidden cost of hiring
Hiring a developer in-house involves costs that are often underestimated beyond the salary: the hiring time itself, generally several weeks to several months to find the right profile, the onboarding time before being fully operational, equipment and tools, and the risk if the role ultimately doesn't match the actual volume of work available over time. This risk weighs more heavily on a small structure, where a poorly sized hire has a proportionally bigger impact on the overall budget.
The hybrid solution
In practice, many companies combine both approaches: an in-house developer ensures continuity, product knowledge, and day-to-day availability, while one or more freelancers reinforce the team temporarily during workload peaks or for specific skills missing internally. This hybrid approach keeps a stable base while retaining flexibility for variable needs.
The dependency risk, in both directions
A project that relies entirely on a single freelancer over time is exposed to a continuity risk if that person becomes unavailable or stops working, without enough documentation for another developer to easily pick up the project. Conversely, a project that relies entirely on a single employed developer is exposed to the same risk if that person leaves, plus the added time and cost of a new hire. In both cases, solid technical documentation of the project greatly limits this risk, regardless of the status of the person developing.
The impact on company culture
An employed developer becomes part of the team day to day, takes part in product decisions, and develops an understanding of the business context that goes beyond the purely technical side. A freelancer, even an experienced and committed one, generally stays more peripheral to these internal dynamics, barring a very long-standing collaboration. For a company whose product evolves quickly and requires technical decisions permanently aligned with overall strategy, this integration has a value that goes beyond a simple hourly-cost calculation.
Freelancer vs in-house developer comparison
| Criterion | Freelancer | In-house employed developer |
|---|---|---|
| Monthly cost | Variable depending on time engaged | 4000 to 7000€/month including charges |
| Long-term commitment | None, can stop at any time | Employment contract, procedure if terminated |
| Availability | According to the freelancer's schedule | Priority, dedicated full-time |
| Product knowledge | Grows with the length of the collaboration | Deep and continuous |
| Flexibility in case of underuse | Total | None, salary owed regardless |
| Suited to | One-off or variable need | Permanent, structural need |
What to remember
- A freelancer suits a one-off or variable need, with no long-term commitment.
- An in-house employed developer is worth it once the development need becomes permanent and structural.
- The cost of an in-house employee (4000-7000€/month) becomes competitive against a freelancer engaged continuously over the same period.
- Hiring has a hidden cost: recruitment time, onboarding, risk of underuse.
- A hybrid approach, combining an in-house employee and occasional freelancers, remains a common and relevant solution.
Frequently asked questions
From what workload does it become better to hire a developer in-house? Once the need becomes permanent, full-time or close to it, over several consecutive months, the cost of an in-house employee often becomes competitive against a freelancer engaged continuously.
Does a freelancer know the product as well as an in-house developer? Not at the start, but a freelancer who works on the same project over the long term ends up acquiring comparable knowledge.
Can you combine a freelancer and an in-house developer? Yes, it's common: an in-house developer ensures continuity, freelancers reinforce the team temporarily during workload peaks or for specific skills.
What's the real hidden cost of an in-house hire? Hiring time, onboarding, equipment, and the risk if the role ultimately doesn't match the actual volume of work available.
In summary
The choice between a freelancer and an in-house developer depends above all on how regular the need is, not on a default preference. If you're unsure of the right sizing for your project, tailored support can help evaluate the best-suited solution.
Frequently asked questions
›From what workload does it become better to hire a developer in-house?
There's no universal threshold, but once the development need becomes permanent, full-time or close to it, over several consecutive months, the cost of an in-house employee (4000 to 7000€/month including charges) often becomes competitive against a freelancer engaged continuously over the same period.
›Does a freelancer know the product as well as an in-house developer?
Not at the same level at the start, but a freelancer who works on the same project over the long term ends up acquiring comparable knowledge. The real difference lies in long-term involvement in product decisions, where an in-house employee is generally more integrated.
›Can you combine a freelancer and an in-house developer?
Yes, it's a common practice: an in-house developer ensures continuity and product knowledge, while one or more freelancers reinforce the team temporarily during workload peaks or for specific skills missing internally.
›What's the real hidden cost of an in-house hire?
Beyond the salary, you need to count the hiring time (often several weeks to months), onboarding, equipment, tools, and the risk if the role ultimately doesn't match the actual volume of work available over time.
