In short: An AI voice agent answers the calls at a car dealership or auto workshop that nobody at the service desk has time for: service appointments, "Is my car ready?", test drives, tyre changes, questions about a recall. It books into the connected calendar, takes down the registration number and the issue, and puts the caller through to a service adviser when a person is needed. With EchoCall this starts at €75 a month for 250 call minutes, with no setup fee. There is no ready-made connection to a dealer management system (DMS). It is connected via webhook, Zapier or Make.
Why the phone becomes the bottleneck at a car dealership
According to its central association ZDK, the German motor trade has around 40,000 businesses with 468,000 employees. [1] In most of them, the workshop business depends on a handful of people at the service desk. They check cars in, explain invoices and call customers about extra work. And the phone keeps ringing.
The DAT Report 2026 shows why every call counts. In Germany, a service cost an average of €542 in 2025 and a repair €604. That is 27 and 30 per cent more than in 2020. At the same time, owners commissioned fewer jobs per car. Almost 60 per cent of car owners have changed their behaviour because of the cost, and many look specifically for workshops that do the repair for less. [2] People who compare prices call several workshops. The job often goes to whoever picks up.
Customers say so themselves. Just over half of franchised-workshop customers see room for improvement at their workshop. Half of those want faster appointments, 35 per cent name getting in touch with the workshop and 32 per cent the opening hours. Customers of independent workshops answer in a similar way. [2]
One figure from the same study is worth knowing before you start. Only for booking appointments and for aftercare can a quarter of respondents imagine a digital process. For every other step, customers want contact with workshop staff. [2] So an AI voice agent does not replace the service desk. It answers the call, books the appointment and hands everything else over cleanly to a person.
Six types of calls and what the agent does with each
| Call | What the caller wants | What the AI voice agent does |
|---|---|---|
| Service appointment | inspection, MOT-style check, tyres, repair | asks for registration, model, mileage and issue, books into the time slots you release |
| "Is my car ready?" | status and pick-up time | gives the status if your system provides it via an interface, otherwise takes a callback request |
| Test drive and vehicle enquiry | model, availability, appointment | takes model, preferred date and contact details, books into the sales calendar or creates a lead in the CRM |
| Recall | Does this affect my car, how long will it take? | answers what is in the knowledge base and books the appointment |
| Breakdown or accident | help, towing, courtesy car | transfers straight to the service adviser or the emergency number, refers to 112 if anyone is injured |
| Parts and accessories | Is the part in stock, what does it cost? | takes the vehicle identification number and the request and passes it to the parts desk |
The difference from voicemail: the customer hangs up with an appointment, not with the hope of a callback. And in the morning, the service desk does not find voice messages but name, registration, issue and booked slot as text in the dashboard.
How a call for a service appointment works
- Greeting with AI notice. "Berger Motors, service desk. You are speaking to our digital assistant. How can I help?"
- Clarify the request. Inspection, the statutory roadworthiness test (HU in Germany), tyre change, a noise, a warning light.
- Take the vehicle details. Registration, model, approximate mileage. For a warning light, the agent asks whether the car can still be driven. If it cannot, it transfers to the service adviser.
- Book the appointment. The agent offers free slots from the calendar, asks about a courtesy car or collection and delivery if you offer them, and repeats the date and time.
- Give guide prices if you want it to. For example for an oil change, tyre change or tyre storage. Everything else waits for the quote after inspection.
- Summary. The conversation lands as text in the dashboard. If you like, a message also goes to Slack or Microsoft Teams, or an email to the service desk.
What missed calls cost your workshop: the calculation with your numbers
We found no reliable industry figures on how many calls go unanswered at dealerships. Your own figure is easy to get. Most phone systems show unanswered calls per day. Count them for a week, and only count the calls that nobody returned later.
Then calculate:
missed calls per week × share of appointment requests × share who book elsewhere × average job value
An example with assumptions, not measurements:
| Assumption | Value |
|---|---|
| missed calls per week, not returned | 20 |
| of which appointment requests | 40 % |
| share who book at another workshop without a callback | 25 % |
| average job value (DAT average for a service) | €542 |
| lost revenue per week | €1,084 |
| lost revenue per month (× 4.3) | about €4,660 |
Put in your own numbers. Even if your result is only a tenth of that, it is still more than the plan you need for these calls. The full method is in the post Missed Calls Cost Revenue.
What an AI voice agent costs for a dealership
With EchoCall you pay for call minutes, about €0.30 per minute, with no setup fee. [3]
| Plan | Minutes per month | Price per month |
|---|---|---|
| Starter | 250 | €75 |
| Basic | 500 | €150 |
| Professional | 1,500 | €450 |
| Business | from 5,000 | from €1,500 |
Phone number and telephony are not included in the plan price. Work out your need like this: calls per day handled by the agent × minutes per call × working days per month. Two examples with assumptions:
- An independent workshop only forwards the calls it does not answer, say four a day at three minutes each over 21 working days. That is 252 minutes, so the Basic plan with 500 minutes leaves room.
- A dealership routes all service calls through the agent at peak times, around 20 a day. At three minutes per call that is 1,260 minutes a month, which fits the Professional plan.
If you also use a chat agent on your website for test drive and appointment requests, it starts at €40 a month for 100 conversations. Each agent has its own knowledge base. Give both the same documents and phone and chat will give the same answers.
Connecting calendar, CRM and DMS
The most common question from dealerships: does the agent book straight into our DMS? The honest answer depends on where your workshop planning lives today.
- Calendar in Google, Outlook, Cal.com or Calendly. The agent books there directly, and only into the appointment types and time slots you release. For small independent workshops this is often the simplest route.
- CRM for sales. The agent creates test drive requests in HubSpot or Salesforce, with model, preferred date and whether the caller wants to part-exchange a car.
- DMS or workshop planning with an interface. EchoCall offers no ready-made connection to a specific DMS. If your system has an interface for appointments or job status, the agent can be connected via your own webhook, Zapier or Make. Ask your DMS provider which data it exposes. Developers can also use the REST API, described in The EchoHub API Guide 2026.
- No interface. The agent takes down the appointment request with a time window, and the service desk enters it. That does not sound like much. But it takes the call out of the morning rush.
Setup in six steps
- Try it without signing up. In the live demo you enter your website address. The demo builds an agent from your public pages in about 20 seconds, which you can call in the browser or write to.
- Create an account. In the EchoHub with 30 voice minutes and 30 chat conversations for 14 days, with no credit card required.
- Fill the knowledge base. Opening hours of service, sales and parts, brands and services, guide prices, courtesy cars and collection, notes on current recalls. You can upload PDF, TXT, Markdown, CSV and JSON, plus single pages or the whole website, which is re-read at a fixed interval.
- Connect the calendar and set transfers. Which appointment types does the agent book itself? Where does it transfer for breakdowns, complaints and warranty cases? Transfer to a phone number is a built-in tool of the agent.
- Book a number and set up call forwarding. Your familiar number stays. In your phone system you decide when calls are forwarded, for example after 20 seconds without an answer, when busy or outside opening hours. The codes for mobile phones are in the post Answering the Phone in the Trades 2026.
- Test. Call it yourself: two inspection appointments, a tyre change, a test drive, a breakdown, a question about an invoice. Wherever the agent struggles, something is missing from the knowledge base.
Outbound calls: recalls, inspection reminders and competition law
In Germany, for recalls over serious risks or non-compliance, manufacturers must use the keeper addresses from the central vehicle register of the Federal Motor Transport Authority (KBA). Keepers who do not respond are contacted again in follow-up campaigns. [4] So keepers receive a letter and then call the dealership. Those are exactly the calls the agent is built for. Put the manufacturer's information on the recall into the knowledge base and it will answer the usual questions and book the appointment. Keepers can also check the KBA recall database to see whether a vehicle type is affected. [4]
It is different when you make the call. Under German competition law, telephone advertising to consumers is only allowed with their prior express consent (§ 7(2) no. 1 UWG). [5] You must document the consent and keep it for five years (§ 7a UWG). [6] Reminders about inspections, the roadworthiness test or tyre changes are meant to bring in a job. So expect them to count as advertising. The easiest way is to ask for consent when the car is checked in. Which occasions work without advertising consent, and how to set up a call list, is covered in the post AI Batch Calling 2026.
Where the agent reaches its limits
- Remote diagnosis. The agent records symptoms, noises and warning lights like a good service desk, not like a master mechanic. The workshop finds out what is broken.
- Quotes. It gives guide prices for standard jobs if you release them. It does not quote for a repair without an inspection.
- Part-exchange. It takes model, year and mileage. It does not give a value, that is for your sales staff.
- Complaints and warranty. An angry customer wants the service manager. The agent records the issue in full and transfers the call or arranges a callback.
- Customers who want a person. Anyone who says "I'd like to speak to someone" is put through as soon as someone is free. That matches what customers expect from their workshop according to the DAT Report. [2]
Data protection and AI disclosure
Since 2 August 2026, callers in the EU must be told that they are talking to an AI (Article 50 AI Act). [7] For phone agents, you write the notice into the agent's first sentence yourself. The editor in the EchoHub reminds you with an info box, and the help centre has example sentences. More on this in EU AI Act 2026: What the AI Disclosure Duty Means for Voice and Chat Systems.
Registration, name and phone number are personal data. Only let the agent ask for what the workshop needs for the appointment. EchoCall's servers are in data centres in Frankfurt and Karlsruhe. You will find the data processing agreement at echocall.de/avv, and the technical and organisational measures and list of subprocessors in the Trust Center.
Frequently asked questions
Can the AI voice agent book service appointments straight into our DMS?
Not through a ready-made connection. The agent books directly into Google Calendar, Outlook, Cal.com or Calendly. If your DMS or workshop planning has an interface, it can be connected via your own webhook, Zapier or Make. Without an interface, it takes down the appointment request and the service desk enters it.
What does an AI voice agent cost for a dealership or workshop?
With EchoCall from €75 a month for 250 call minutes, about €0.30 per minute, with no setup fee. Phone number and telephony come on top. A workshop that only forwards missed calls usually manages with 250 to 500 minutes.
Does the agent replace the service desk?
No. It answers calls when nobody is free, books appointments and sorts the rest. Vehicle check-in, quotes, complaints and the conversation about extra work stay with your service advisers.
Can the agent tell a customer whether their car is ready?
Yes, if your workshop planning provides the job status through an interface and the agent accesses it via webhook. Without that connection, it records the question as a callback request.
Can the agent call customers about inspections or the roadworthiness test?
For private customers only with their prior express consent, because such reminders can easily count as telephone advertising (§ 7 UWG). Ask for consent when the car is checked in and document it. Incoming calls, for example after a manufacturer's recall letter, are not affected.
Does the agent also talk to customers who do not speak German?
Yes. The agent speaks more than 30 languages and can detect the caller's language automatically. Automatic detection can be switched off for each agent.
Do customers notice that they are talking to an AI?
Yes. The AI Act has required the notice since August 2026, and the agent says so in its first sentence. Anyone who would rather speak to a person is transferred or called back.
