If you are collecting quotes you will find figures from €29 to well over €900 a month, all described the same way. They are not the same thing: they are three different technologies. Here is what you pay for in each — including the part that argues against us.
When two offers are described identically and sit €800 apart, the first thought is that someone is padding the price. Sometimes they are. But what usually sits underneath is that they are selling different things under the same name.
| Tier | What it is | Per month | Setup |
|---|---|---|---|
| 1 | Drawn flows: if they tap this button, say this | €29 – €199 | €0 – €300 |
| 2 | Assistants that converse but do not execute | €150 – €500 | €0 – €1,000 |
| 3 | Systems that converse and execute against your calendar | €460 – €1,840 | €2,000 – €15,000 |
The border between tier 2 and tier 3 is a single verb: execute. A tier-2 assistant holds an excellent conversation and finishes with "a colleague will confirm your appointment". The customer had a good experience and your team has exactly the same work still waiting.
A hand-drawn diagram. You pay for the tool that lets you draw it and for the hosting. It is cheap because there is little to maintain: no language model burning usage, no integration with your calendar, nobody tuning anything.
When it is the right call: if all you need is to answer four common questions and you book nothing, this is plenty and it is the most sensible thing you can do with the money. We would say so either way.
Here there is genuine AI, and that costs: every reply consumes processing charged by usage. You are paying for natural-language understanding, not for the ability to act.
Everything in tier 2 plus the work of wiring the system to your real calendar and — this is what actually costs money — guaranteeing that what it does is correct: that it checks before promising, that it does not duplicate a booking when the customer insists, that it undoes its own work if an operation fails halfway, and that it does not fill in facts it does not have.
None of that work shows up in a demo. It shows up six months later, in the fact that you have not had to check what it says.
Ask them of any quote, ours included. If the person selling cannot answer them concretely, you are looking at tier 1 or 2 even when the price is tier 3:
An answer along the lines of "that's handled in the prompt" is not a yes. It means they have asked the model to behave, not that the behaviour is guaranteed. That is the difference between an instruction that can be skipped on an odd day and a check that runs every time.
It is the alternative most people consider, and it deserves an honest answer: for mechanical tasks — when this arrives, send that — automation tools are excellent and cheap.
The trouble starts when what is on the other end is a conversation. The data does not arrive tidy or complete: it arrives in pieces, with changes of mind and questions in between. And three costs are invisible at the start:
It adds up if you have someone to maintain it and your volume is low. It stops adding up the moment one mishandled booking costs you more than the price difference.
The usual question is "is it expensive?". The useful one is "compared to what?".
At a €200 average ticket and a 65% contribution margin:
| Monthly fee | Saved appointments/month that cover it |
|---|---|
| €149 | 2 |
| €390 | 3 |
| €690 | 6 |
| €990 | 8 |
Note that this counts margin, not revenue. A €200 appointment is not €200 of profit: it consumes product and consumables. Presenting gross revenue as "savings" is the most common error in these calculations and the first thing anyone who can read a set of accounts will spot.
You can run it on your own figures in the ROI calculator: it is built to tell you it does not pay for itself yet, and if that is the answer, it says so.
Before signing, check these five points in any offer:
For reference, here are our numbers: setup from €290 to €1,690 depending on plan — under two months of fee, and only if you continue — extra conversations at €0.25, extra minutes at €0.20, no lock-in and no service cut-off when you pass the limit. Full plans on the pricing section.
Because it is not the same thing. The €99 offer is usually a drawn flow that cannot check your calendar; the €690 one checks real availability and executes the booking. The question that separates them is not price, it is "does it check before promising a time?".
There are free tiers of flow-builder tools, and they are fine for answering four common questions. None of them book against your real calendar, because that requires an integration that costs money to maintain. If what you need is to inform, a free one may be enough.
In our case €290 to €1,690 depending on the plan, always under two months of fee. It is not a licence being switched on: someone loads your services, prices and durations, connects your number and your calendar, configures your real opening hours and trains your team. It is charged only if you continue after the trial, and waived if you pay a quarter up front.
On the open market, building a system that genuinely checks your calendar and executes bookings runs €2,000 to €15,000. With automation tools you can cut that initial figure a long way, but the real cost is not building it — it is maintaining it and covering the odd cases.
It should be one customer talking to you over 24 hours, not each message. If someone sends thirty messages in an afternoon, that is one conversation, not thirty. Worth asking explicitly, because it changes the real price by a factor of five or ten.
Then you need more saved appointments to cover the fee, and the larger plan may not pay for itself — or any of them may not. It is arithmetic, not an opinion: run it on your figures in the calculator. If it says it does not pay, it does not pay.
Put in your ticket, your appointments and your real no-show rate and see what comes out. And if you would rather watch it running on your own services and prices, the demo is 20 minutes and costs nothing.
