You need IT capacity, but in which form? Do you take someone on permanently, or hire flexibly via a freelancer or intermediary? It is a choice with major consequences for your costs, your risks and your agility. What is smarter for your situation?
In this article I place permanent contract and flexible hiring honestly side by side: what does it cost, which risks do you run, and when does which form fit? No plea for one side, but a sober comparison so you make a substantiated choice.
This blog is for clients: IT managers, HR and decision-makers torn between hiring permanently and hiring flexibly.
Honest disclosure: I place IT freelancers, so I have an interest in flexible hiring. That is why I also honestly name when a permanent contract is the better choice. My concern is what fits your situation, not what suits me.
What is the core difference between permanent and flexible?
A permanent contract binds someone to your organisation long-term, with security for both sides but also obligations. Flexible hiring brings in expertise for as long as you need it, with more agility but without the binding. The core is a trade-off between security and flexibility.
Neither is better by definition; it depends on your need. If you structurally and long-term need the same capacity, the balance leans towards permanent. If you temporarily need specialist expertise or fluctuating capacity, flexible is often smarter. Below the comparison on the points that matter.
What does permanent versus flexible cost?
At first sight, a permanent employee seems cheaper per hour than a hired freelancer. But a permanent contract adds employer costs: social contributions, pension, continued pay during illness, holiday pay and development costs. Those make the actual cost of a permanent worker higher than the bare salary.
Flexible hiring has a higher hourly rate, but you pay only for the hours you need, without fixed costs and without risk during idle time. Which form works out cheaper depends on how structurally you need the capacity. Want to know which costs often stay hidden in hiring? Read our blog on the hidden costs of IT hiring.
Which risks do you run with each form?
With a permanent contract, the risk is in the binding: if you take someone on and your need changes, you are stuck with continued pay and dismissal rules. You also carry the risk of illness and underutilisation. A wrong permanent hire is expensive and hard to reverse.
With flexible hiring, the risk is mainly in continuity and compliance: a hired worker can leave, and you must arrange the Dutch DBA Act well to avoid disguised employment. An intermediary can reduce both risks by arranging replacement and safeguarding compliance. Both forms thus have risks, but of a different type.
What about the Dutch DBA Act with flexible hiring?
That is an important point of attention. Since 2025, the Dutch DBA Act is actively enforced. If you hire a freelancer long-term and embedded as if an employee, you risk the relationship being seen as disguised employment, with a back-tax assessment as a result. Flexible hiring thus requires care.
Well arranged, this is no obstacle. Steer on a defined result, avoid embedding, and for long-running assignments possibly choose the intermediary construction, where the risk is covered while the IT professional stays independent.

When do you choose permanent, and when flexible?
The rule of thumb: choose permanent for structural, long-term capacity that touches the core of your organisation, and flexible for temporary, specialist or fluctuating need. Many organisations combine both: a permanent core, supplemented with flexible hiring for peaks and specialisms.
A few situations and what usually fits:
- Structural, long-term, core activity → leans towards permanent contract
- Temporary project or peak → flexible hiring
- Scarce, specialist expertise you rarely need → flexible hiring
- Quickly scalable capacity needed → flexible hiring
- Knowledge you want to keep permanently in house → permanent contract
The best choice is often not either-or but both-and: build a permanent core and use flexible hiring for what does not fit in it. That way you combine security with agility, and do not pay for permanent capacity you do not structurally use.
Frequently asked questions about permanent versus flexible hiring
Is flexible hiring more expensive than taking someone on permanently?
Per hour usually yes, but you pay only for the hours you need, without employer costs and without risk during idle time. A permanent worker costs more than the bare salary due to contributions, pension and continued pay. What is cheaper depends on how structurally you need the capacity.
What is the biggest risk of a permanent contract?
The binding. If your need changes after you have taken someone on, you are stuck with continued pay and dismissal rules. A wrong permanent hire is expensive and hard to reverse. Flexible hiring gives more agility on that point, at a higher hourly rate.
Do I run Dutch DBA Act risk with flexible hiring?
Only if you arrange it sloppily. If you hire a freelancer long-term and embedded as an employee, that can count as disguised employment. Well arranged, with a defined result and without embedding, flexible hiring is fine. For long-running assignments, the intermediary construction can cover the risk.
Can I combine permanent and flexible?
Yes, and that is often the smartest approach. Build a permanent core for structural knowledge and capacity, and supplement with flexible hiring for peaks, projects and scarce specialisms. That way you combine security with agility and do not pay for permanent capacity you do not always use.
What is smarter for scarce expertise?
Usually flexible hiring. Scarce, specialist expertise you often do not need permanently, and taking such a person on permanently is expensive and awkward if the need fluctuates. Hiring flexibly gives you access to that expertise exactly when you need it, without structural obligation.
Conclusion: choose on your need, not on the hype
Permanent contract or flexible hiring is not a matter of which is better, but of what fits. Permanent pays off for structural, long-term core capacity; flexible for temporary, specialist or fluctuating need. Calculate the actual costs and risks of both honestly, and choose on your situation.
For whom is flexible hiring most suitable? For those seeking agility, scarce expertise or temporary capacity. For whom less? For those wanting to build structural, permanent knowledge in the core of the organisation; then permanent is often better.
My advice: think not in either-or but in both-and. A permanent core supplemented with flexible hiring gives most organisations the best balance between security and agility. Determine per need which form fits.
