The real cost of an AI agent against hiring another person

An Agent Build is €4,000 to €6,000, fixed, paid once. A hire is a salary that arrives every month plus a ramp before it pays anything back. The agent is the right call when the work repeats and a person still approves each run. The hire is the right call when the work needs judgement.

The quick version:

• An Agent Build is a fixed €4,000 to €6,000, paid once against a fixed scope.
• A hire is a recurring cost, and we will not publish a fake average for it.
• Dutch market rates put that build at roughly five to eleven senior developer days.
• An agent owns no decisions, so a person on your team approves every run.
• The real question is which hours in your backlog deserve a person.

What the Dutch market charges for automation work

The Dutch market has published rates for most of this work, so start there rather than with anyone's quote. Our own prices come further down the page, and the one build we can show you publicly is the Slack content agent we run in production.

The hourly band comes from two Dutch sources. Knab reports what a self employed AI specialist charges at the low end, and Consultant.nl reports the AI consultant average at the high end. The build and retainer bands both come from the agency pricing collected by Arsum and Digital Agency Network.

The senior developer day rate is the one row with no named publisher behind it. It is the band we see quoted across the Dutch market, and we would rather say that plainly than attach a source it does not have.

What a hire costs that the salary line does not show

A hire costs a good deal more than the salary line, and this is the point where we stop handing you numbers. We are not going to publish an average cost of a Dutch employee.

The honest figure depends on your salary band, your contract type and your pension arrangement. A made up average would only make this post look more authoritative than it is.

What holds regardless of your own figure:

• a salary arrives every month whether or not the backlog does
• nobody is productive on day one, and during the ramp the new person produces less than the person training them
• a workflow that lives in one person's habits leaves when that person leaves
• the hiring itself takes weeks of attention you are already short of, before any of the work happens

All of that is an argument for costing a hire properly, instead of putting a build price beside a monthly salary and calling it a comparison. For the scope side of the same question, we wrote up what an agent can and cannot automate in a content team.

The arithmetic on a fixed price build

The arithmetic starts from one fixed number. An Agent Build is €4,000 to €6,000, with the price fixed against a written scope.

Set against the market anchors above, that price works out at roughly:

• 29 to 50 hours of freelance AI and automation specialist time
• five to eleven days of senior developer time
• the top of the small build band, or the bottom of the mid build band

The build price is a band because the jobs are not the same size. One workflow, one integration and one approval gate is not the same job as one that touches your CRM, your ticketing system and something a customer sees.

The hour and day figures spread wider still, because the market rates behind them are bands as well. Treat them as an order of magnitude, not a quote.

So the price is only fixed once the scope is, which is what the €1,500 Blueprint Sprint is for. A single number quoted before scoping is a guess, and the guess comes back later as a change request. If you want the cheapest version of that scoping step, read what happens inside the €500 Agent Audit.

What a hire buys that an agent does not

A hire buys judgement, and that is the honest gap. A person can look at an odd case, decide it is odd, and stop. An agent runs the process it was given, and it pauses for a human only where the design says to pause.

That is why every run in the build we have live stops at a human approval gate, and does not continue until someone answers. It keeps a named person accountable for anything that goes out under your company's name.

Someone also has to own the agent day to day: check it is behaving, adjust it when the process changes, notice when it stops earning its keep. That is a light commitment rather than a role, and any quote that leaves it out is pricing the demo instead of the system.

Running costs after the agent goes live

Running costs do not stop when the agent goes live: model usage, hosting, and the person tuning it. We are not going to invent your figure for that.

The one published band we have covers the agency side of that, not your model bill. Arsum and Digital Agency Network put ongoing SMB work at €460 to €4,600 per month. A spread that wide tells you how much it depends on what got built.

One internal workflow with one integration sits nowhere near the top of that band. Ask for the running cost in writing before you sign anything, including anything of ours.

FAQ

These are the questions founders ask us when they are holding a build quote and a job description at the same time.

Is an AI agent cheaper than hiring someone?

An AI agent is usually cheaper as a one time cost, because a build is paid once while a salary recurs every month. That comparison only holds when the work repeats enough for an agent to run it. For work that needs a judgement call on every case, the hire is cheaper over any real time horizon.

What does an Agent Build cost at Arrox?

An Agent Build costs €4,000 to €6,000, a fixed price against a fixed scope. The scope is written first, in the €1,500 Blueprint Sprint, so the number is not a guess. Running costs after go live are quoted separately.

Why will you not publish an average employee cost?

An average employee cost depends on your salary band, your contract type and your pension arrangement, so any single figure we published would be wrong for most of the people reading it. We would rather give you the market rates we can actually source and let you set your own salary number beside them.

Where does the senior developer day rate come from?

The senior developer day rate of €550 to €750 is the one figure in this post with no named publisher behind it. It is the band we see quoted across the Dutch market. We flag it as unsourced rather than attaching a publisher it does not have.

Does an agent need someone to look after it?

An agent needs someone to look after it: to check it is behaving, adjust it when the process changes, and switch it off when it stops earning its keep. That is a light ongoing commitment rather than a job. Any quote that leaves it out is pricing the demo.

What is the cheapest way to find out which one I need?

The cheapest way to find out is the €500 Agent Audit, which is ninety minutes plus a two page memo. It names the workflow worth building and the one that is not. Money back if the memo is not useful to you.

Deciding which hours deserve a person

The hours that deserve a person are the ones where someone has to weigh an odd case and carry the call. Everything else is assembly, and assembly is what a build is for.

A build is a one time cost against a workflow that runs indefinitely. A hire is a recurring cost against a role that grows. Most teams end up needing both, in that order, because the hire is worth more once the assembly work is off their desk.

If you want to know which of your workflows sits on the right side of that line, that is what the €500 Agent Audit is for. Ninety minutes and two pages, and you will know the number you are actually deciding about.
