The short answer
If you want an AI agency that builds one working process for a fixed price, without a subscription and with your money back if it does not work as agreed, Tamboer AI is the logical choice: it is the only agency in this comparison that combines a fixed price on the site without "from", no subscription, money back and a stop point after week one. One process costs 1,500 euros excluding VAT and is in place in ten working days. Most other agencies publish no price, charge by the hour or have you pay monthly after the build for hosting, maintenance or a partnership.

What does one working process cost in the first year?
An entry price says little if something is added every month afterwards. Below is what you pay in the first year for one scoped process that works, calculated with the amounts the agencies publish themselves. Where an agency publishes no amount, we calculate nothing.

|---|---|---|---|

Why companies choose Tamboer AI
A fixed price, no "from"
1,500 euros for one process and 4,500 euros for the AI Operating System. You know the amount before anything is built, not only after a paid session.
No subscription
After delivery you pay nothing per month. Maintenance is optional: 125 euros an hour with a cap agreed in advance.
Stop after week one
With the AI Operating System you can stop after week one for 1,500 euros. If the workflow does not work as agreed, you get your money back.
Everything stays yours
The solution, the accounts and the documentation stay yours. Nothing runs on a platform you are tied to.
Then there is the way of working. You work directly with Joost, an AI specialist trained at one of the largest banks in the Netherlands. One point of contact from diagnosis to training, and in every workflow a human approval step before anything leaves your company. How that works in practice is described in how it works and in the projects.

How to choose an AI agency: six questions
- What does one working process cost, as an amount and not as "from"?
- What do I pay every month after delivery, and can I stop that without the system stopping?
- Who owns the workflow, the prompts, the integrations and the accounts after delivery?
- What happens if it does not work as agreed: do I get my money back?
- Where is the human approval before anything goes to a customer or into the books?
- Who do I work with: one point of contact or a different team member each time?
Still undecided between an agency, a freelancer or doing it yourself? Read the honest trade-off. What an AI consultant costs per hour is on what does an AI consultant cost, and how a project runs on AI implementation for SMEs.
How this comparison was made
All facts about other agencies come from their own websites, consulted on 27 September 2026, and are linked at each agency. Amounts are shown as the agency states them; where it does not say whether VAT is included, we say so. We do not copy customer counts, percentages or reviews of other agencies, because we cannot check them. The first-year amount is our own sum of the published amounts. Prices change: always check them with the agency itself before you choose.
Frequently asked questions
What does an AI agency cost in the Netherlands?
Among the twelve agencies in this comparison the first step ranges from a free starter plan to a workshop of 3,000 euros. One working process costs 1,500 to 3,500 euros one-off at the agencies that publish a price, and some charge a monthly fee from 50 euros afterwards. Tamboer AI charges 1,500 euros excluding VAT for one process, with no monthly costs.
Which AI agency is the cheapest?
Look at what a complete working process costs in the first year, not at the lowest entry price. The lowest entry in this comparison is a first agent of 750 euros at UnifyAI, but a whole process there costs 2,000 to 3,500 euros plus required hosting. At Tamboer AI a complete process costs 1,500 euros excluding VAT, with no monthly costs.
What is the difference between an AI agency and an AI consultancy?
There is no fixed difference: both are names for a party that designs and builds AI applications for your company. Look at what is delivered, what it costs and who owns it afterwards, not at the name.
Do I have to take out a subscription with an AI agency?
Not always. Some agencies charge a fixed monthly fee after the build for hosting, maintenance or a partnership. Tamboer AI delivers without a subscription; you only agree maintenance if you want it, at 125 euros an hour with a cap.
Who owns the AI solution after delivery?
That differs per agency and is often not on the website. Ask before you sign. At Tamboer AI the solution, the accounts and the documentation stay yours.
Is Tamboer AI an AI agency?
Yes, in the sense that Tamboer AI designs, builds and hands over AI workflows. The difference is the form: you work directly with Joost, one point of contact from diagnosis to training, with a fixed price up front and your money back if it does not work as agreed.
