How much does an employee really cost in Belgium? Comparison with an AI agent
When an entrepreneur considers recruiting, he often thinks about gross salary. But the real cost of an employee in Belgium goes well beyond that. Employer charges, paid leave, training, equipment, risk of turnover... The final bill is systematically higher than expected. So what happens when we honestly compare it to a tailor-made AI agent?
The real cost of an employee in Belgium: the complete calculation
In Belgium, employer contributions represent approximately 25 to 33% of gross salary. But that's just the first layer. Here is what you actually pay for an employee at €35,000 gross annually:

An employee at €35,000 gross actually costs your company between €55,000 and €65,000. And this figure rises quickly with seniority and increases.
What an IA Partna agent costs: the pricing structure
A tailor-made agent system is based on two elements: a single implementation, the scale of which depends on the size of the company and the number of tools to be connected, and monthly monitoring which covers maintenance, security patches, ongoing optimizations and the addition of new skills. The scope and budget are established during the scoping audit, based on your actual processes — not a standard grid.

The comparison that changes everything
If we compare over 12 months (setup amortized over the first year), the difference is striking. For the same type of work (email management, team coordination, reporting, customer follow-up), here is what you spend:

What the AI agent does not replace (let's be honest)
An AI agent is not a silver bullet for everything. It excels in repetitive, structured and high-volume tasks: email processing, reporting, coordination of actions, lead tracking, calendar management, document synthesis. On the other hand, complex strategic decisions, high-value human relationships or deep creativity remain areas where humans retain the advantage.
The Partna approach
We are not building an agent to replace your team. We build an agent to absorb all the tasks that shouldn't be done by your team in the first place, and which currently cost a lot of time and concentration.
The question to ask yourself is not “how much does the agent cost?” but “how much does the work it could absorb cost me today?” Here is a 4-step method:
List your 5 most repetitive tasks
Review your week. Recurring emails, reporting, reminders, planning... Note all the tasks that you or your colleagues do in the same way, week after week.
Focus on tasks with clear logic and predictable rules. These are the best candidates for automation.
Estimate actual weekly time
For each task, how many hours per week are devoted to it? Be specific. Leaders systematically underestimate the time spent on administrative tasks by 40 to 60%.
Track your time for a full week. The total will almost always surprise you.
Calculate the busy hourly cost
Multiply the estimated time by the actual hourly cost of the person performing the task. For an employee earning €35,000 gross: around €32/hour charged. Example: 5h/week x €32/h x 52 weeks = €8,320/year for a single task.
If it's your own time, value it for what you could generate by working on growth.
Compare with the cost of an AI agent
Add up the actual annual cost of the tasks the system would take over, then compare it to the budget established during the audit. If the first greatly exceeds the second, the investment is justified; if not, we will tell you.
In practice the threshold sits around 7 to 8 hours a week of repetitive tasks across the whole team. Below that, an off-the-shelf tool will serve you better, for less.
Conclusion
To remember
The real question is not whether you can afford an agent system. It is whether the tasks it would take over already cost you more than it does. The scoping audit exists precisely to answer that, with figures.
