The owner of an administratiekantoor in Breda, doing the books and tax returns for about two hundred ZZP'ers and small companies, paid a telefoonservice every month and found the invoice climbing every spring, when the aangifte inkomstenbelasting season brought twice the usual calls. What the invoice did not show was the hour a day the owner and one assistant spent ringing clients back to answer the question the telefoonservice had written down.

Key takeaways
- Dutch telefoonservices usually charge a monthly bundle plus a per-call rate, so costs rise in the busiest months.
- An AI receptionist is usually a setup fee plus a monthly amount tied to volume, and it can answer many of the questions itself.
- The comparison that matters includes the time spent returning calls, which appears on neither invoice.
How telefoonservices charge
Most Dutch telefoonservices sell a monthly subscription that includes a number of calls, with each additional call charged separately, and extras for things like appointment booking or longer calls. For a small office the monthly bill is modest in a quiet month and noticeably higher during the tax season.
What the subscription buys is a friendly person answering in the company name and passing on a message, which is a reasonable service for the price and leaves the actual answer to the office.
How AI receptionist pricing works
An AI receptionist usually costs a one-time setup fee, which covers building the conversation and connecting the office's systems, plus a monthly amount linked to call volume. Once running, an extra call in April costs very little more than a call in August.
Setup cost depends mostly on integration. An agent that answers from the office's own information and books into Outlook is simpler than one that also reads client files in Exact Online or Twinfield and checks which documents a client has already uploaded.
The cost that appears on neither invoice
For the Breda office, the real expense was the callbacks. Clients ringing about deadlines, missing documents, or whether their aangifte had been submitted all needed an answer, and a message on a telefoonservice pad did not provide one.
An AI receptionist can answer many of those from the office's own systems, such as whether documents have arrived, what the deadline is, or when the appointment is, so the callbacks shrink to the questions that genuinely need an accountant.
Working out which one pays
The practical calculation starts with a month of call logs and the telefoonservice invoice. Count the calls, estimate how many needed a callback, and put an hourly value on the time spent returning them, then compare that total with the cost of an AI receptionist for the same volume.
For a small office with few calls and simple messages, a telefoonservice can remain the cheaper option, and we will say so. For an office whose callers mostly need an answer rather than a message, the numbers usually favour the agent.
Common questions
What does an AI receptionist cost compared with a telefoonservice?
A telefoonservice usually charges a monthly bundle plus per-call fees. An AI receptionist usually has a setup fee plus a monthly amount tied to volume. Which is cheaper depends on your call volume and how many calls need a callback.
Is an AI receptionist cheaper for a small office?
Not always. For low volumes and simple messages a telefoonservice can be cheaper. The AI tends to pay off when callers need answers from your own systems rather than a message.
Can it connect to Exact Online or Twinfield?
Yes, where the software allows it, so the agent can answer questions such as whether documents have been received.
