Sample day with two people on the phone. The red zone starts where your team is full. From there, Max answers in parallel.
Bosch Car Service Brenner in Mannheim had sharply rising call volumes, too little staff and a call center costing €1,800 a month. Today every call goes to Emma. In the video, authorized officer Jochen Schattke shows how this works in the workshop (in German).

“We used to miss calls when several customers called at the same time. With ScaleTalk, that has changed completely. Easy to use and quick to set up. Since then, no call goes unanswered.”

Three real test calls: Max books a tire change and a test drive from a listing, Marie answers a status question. Pick a conversation and play it back. On the right, you see what ends up as a finished case in your calendar and your system.
The recording is in German; the transcript is translated.
Press play and the transcript follows along live.
Play a customer who wants to switch to winter tires, or ask whether your car is ready. After you sign up, the number is shown so you can call right away. Two minutes on the phone show more than any feature list.
From conversations with workshops, dealerships and branch chains, with evidence. On the right, you see what Max changes about each one.
In October and around Easter, everyone wants an appointment at the same time. Whoever hits a busy signal calls the next shop.
“What really overwhelms us are the tire change appointments.”
Remedy
Max answers every call in parallel and books the change directly into the workshop calendar.
A customer is standing at the front with keys in hand while the phone rings. One of them has to wait. And staff is scarce.
Occupations in automotive technology are on the shortage list, among the ten largest shortage occupations at skilled-worker level by employment.
Remedy
Max takes over appointments and standard questions. Your team stays with the customer on site.
Every customer whose car is in the workshop wants to know when they can pick it up. The answer is in the system, but someone has to look it up.
At Bosch Car Service Brenner, about 850 calls a month run through the AI, and not a single one is missed.
Remedy
Max finds the order via the license plate and tells the customer right away whether the car is ready.
Prospects call in the evening and on weekends, when the listing is fresh. By the time someone gets back to them, the customer is often already at the next dealer.
It takes an average of 4.4 hours for salespeople to respond to an inquiry via the dealer website, versus 1.1 hours for inquiries by phone.
Remedy
Max checks the inventory, books the test drive and asks about the trade-in right away.
Max recognizes from the first sentence what it is about and sees the case through. Under each case, you see where the result lands.
Checks whether the wheels are in storage, books a waiting or drop-off appointment and sends the confirmation by SMS.
Workshop calendar, wheel storage
Asks for mileage and loaner car, books the appointment with service reception.
Workshop planner in the DMS
Finds the order via the license plate, gives the status and notes the pickup time.
Order status from the DMS
Checks the inventory, books the test drive and asks about a car for trade-in.
Lead in the CRM, salesperson's calendar
Takes down the desired rate and term. Sales does the math; Max doesn't quote any figures of his own.
Callback for sales
Takes down the part and license plate to make sure it fits. The parts department gets back with price and delivery date.
Case for the parts department
Stays calm, gives the most important safety advice and connects immediately to your breakdown service.
Directly at the breakdown service
Takes the frustration seriously, promises nothing and creates the case with the responsible service advisor.
Personal callback
Max works with the systems your dealership already uses: dealer management, workshop planners, vehicle marketplaces and CRM. He knows customer, vehicle and order and enters every appointment where your team works.
Recognize the customer
Even before Max says “Good day”, he looks up in the DMS, based on the phone number, who is calling and which vehicle belongs to them.
→ GET /customers?phone=…
← Customer with vehicle MA-KL-1234
Know the order and inventory
Max sees the order status in the workshop, the stored wheels and whether the car from the listing is still in stock.
→ GET /workshop/orders?plate=…
← Order complete, invoice at the cashier
Enter the appointment
The appointment goes into the workshop planner, the test drive into the salesperson's calendar, the lead into the CRM. The customer gets an SMS.

If your DMS or workshop planner has an interface, we connect Max directly. Through n8n, Make or Zapier, we link several systems in one workflow, for example entering an appointment in the workshop planner and notifying service reception in Teams at the same time.
Listed are systems with a documented or officially offered interface. Brand names belong to their respective owners. We set up the integration for your setup in the needs analysis.
Tire season simulator
“In July and August the call rate is fairly manageable,” a branch chain told us. Not in October. Pick a month, enter your calls and your people on the phone and play back the day. You see when your lines are full and how many calls hit a busy signal without Max.
1. Choose a month
Rule of thumb “from O to O”: winter tires from October to Easter.
2. Enter your numbers
The defaults are sample values, not industry figures. Enter the numbers from your phone system and the model calculates with your business.
3. A peak-season day in October

On average, about 24 of 157 calls (15%) hit a busy line on a day like this. In a week with five opening days, that is about 118. With Max, none of them is turned away, because he handles any number of calls at the same time.
Model calculationHow the model works: opening hours 7 am to 6 pm, calls randomly distributed with somewhat more traffic in the morning, call duration varies around your average, average of 30 simulated days. Anyone who hits a busy line counts as not answered, even though some try again later. No measured data from car dealerships, only your inputs.
License plates are a delicate spot for any voice AI: short letter sequences, dialects, workshop noise in the background. That is why Max checks the format, reads every plate back in the spelling alphabet and only writes it to the log once the customer has said yes.
Type in a license plate, feel free to make it incomplete on purpose or leave out the spaces. Then you see when Max asks instead of guessing.
MA KL 1234
Let me repeat to be sure: MA as in Mannheim. Then K as in Kaufmann, L as in Ludwig. And the number one, two, three, four. Is that correct?
Simplified simulation in the browser. In a real call it works the same way: check the format, read it back in the spelling alphabet, have it confirmed. Only then does the license plate go into the log.
Outbound calls are the biggest lever for full workshop days and the most sensitive part. Tap an occasion, and the traffic light shows the classification.

How customers book their workshop appointment: by phone
DAT Report, cited by AUTOHAUS: “Workshop appointments preferably by phone, hardly any add-on business”, 10/07/2025
What workshop customers who see room for improvement want
shorter wait for appointments
easier way to reach the workshop
more convenient opening hours
And: only a quarter of car owners can imagine digital appointment booking and aftercare. The rest want contact with people. One more reason not to replace the phone with a form, but to staff it better.
DAT Report 2026, short report, Deutsche Automobil Treuhand. Survey of 2,068 car owners, October 2025. Shares relate to customers who see room for improvement (52% for brand workshops, 49% for independent workshops).
From €99 per month. Costs depend on your call volume, not on headcount. This is what it looks like for a workshop that previously paid for a call center.

For context
An extra person just for the phone is quickly in demand during the season and hardly busy in summer. Automotive sales professionals earn a median of €4,238 gross per month full-time, skilled automotive technicians €3,755.
Max doesn't replace anyone at reception. He makes sure your team stays with the customer while the phone still gets answered.

Art. 50 EU AI Act
Since August 2, 2026, an AI that talks directly with people must say so. With Max it sounds like this, and then it is immediately about the request:
Greeting
“Good day, this is Max, the digital assistant at Autohaus Muster. How can I help you?”
Anyone who prefers to talk to a person is transferred or called back, with everything already captured.
GDPR
Customer data such as name, license plate and phone number is processed on servers in Frankfurt and stays in the EU. You get a data processing agreement under Art. 28 GDPR.
Section 201 StGB
Unauthorized recording of the non-publicly spoken word is a criminal offense. That is why Max only records if the caller consents. Otherwise you get a summary with fixed fields.
Sections 7 and 7a UWG
Advertising calls to consumers only with prior express consent, which is documented and kept for five years. Order-related calls and requested callbacks are the core.
General information, not legal advice.
From conversations with workshops, branch chains and partners, anonymized. Where Max has a limit, we say so.
“… who have to remember names, license plates and so on … that gets dull over time.”
A fair concern. Max checks the German license plate format, reads every plate back in the spelling alphabet and only writes it to the log after the customer says yes. Try it above in the license plate test.
“Then the hit rate is somewhere around 50 percent.”
Max only passes on what you store: services, prices, opening hours. Which oil, which part, which repair is for your workshop to decide. For technical questions, Max connects or creates the question as a case for a callback.
“… that I'm now basically creating extra work for myself with a phone thing … that wouldn't be an option.”
Max books appointments directly into your Google or Outlook calendar and answers standard questions himself. A callback is only created when a human is really needed.
“… and the customer then stands at the counter on Monday and says, they promised me that.”
Every booked appointment is sent to the customer by SMS, plus there is a call log. What was promised is in black and white.
“… things like that need to be visible fairly quickly and briefly.”
Fixed fields instead of a novel: request, license plate, preferred appointment, callback number. You only get the transcript if you want it.
“… one, two, three or four, five, six, just normal like on a hotline.”
Instead of reading out six menu items, Max asks once what it is about and assigns the request to your fixed categories: tire change, inspection, service, remaining work, complaint.
“… with our seasonal approach it's really not that easy to calculate with a model like that.”
Entry is at €99 per month. How the model fits your spring and autumn peaks, we calculate in the needs analysis with your real call numbers.
“… forwarding 70 different lines to 70 different destination numbers.”
Every location keeps its number. Max knows which branch was called and forwards to the right reception. Simultaneous calls are not limited.
Roughly three kinds: AI phone assistants that answer calls and make calls themselves, chatbots on the website, and AI features in dealer management and workshop systems. In service, most decisions are made on the phone: according to the DAT Report, 66% of customers of brand workshops and 63% of customers of independent workshops book their appointments by phone.
ScaleTalk is an AI phone assistant for exactly these calls, inbound and outbound, on your existing number.
ScaleTalk starts at €99 per month. Costs depend on your call volume, not on the number of employees. For comparison: Bosch Car Service Brenner now pays about €250 a month for roughly 850 calls; before that, the call center cost €1,800.
Yes. Max understands freely spoken sentences, asks follow-up questions and books appointments during the call, with no keypad menu. At the start he says that he is an AI, as Article 50 of the EU AI Act has required since August 2, 2026. The fastest way to convince yourself is the test number on this page.
For a dealership and workshop, the one that can reliably do four things: read back license plates and have them confirmed, book appointments directly into the calendar, warm-transfer to service reception or sales, and make outbound calls only where they are allowed. Check exactly that in a test call before you decide.
No, there is no fixed date. Germany has a situational requirement: in case of black ice, snow-covered roads, slush, ice or frost, you may only drive with suitable tires (Section 2 (3a) StVO). “From O to O”, meaning October to Easter, is only a rule of thumb.
This is exactly the question customers ask constantly in season. Max answers it from your knowledge base and books the appointment right away.
On the inspection sticker on the rear license plate: the number at the top shows the month, the number in the middle the year. The date is also in the vehicle registration document (Zulassungsbescheinigung Teil I). Cars must go to their first general inspection after 36 months, then every 24 months (Section 29 StVZO with Annex VIII).
Max can handle this for your customers: those who have consented get a call before it expires and an appointment right away.
In many businesses, the service advisor receives the vehicles, discusses repairs, creates work orders and estimates, and hands the car back. The service assistant organizes everything around that: phone, appointments, invoices, loaner cars.
Max takes over the phone part: appointments, standard questions, callbacks. Advice at the vehicle stays with a human.
Under Section 7 (2) No. 1 UWG (German Unfair Competition Act), advertising by phone to consumers without prior express consent is an unreasonable nuisance, and to businesses without at least presumed consent. Consent must be documented and the proof kept for five years (Section 7a UWG).
Calls about an ongoing order, such as “Your car is ready”, and callbacks the customer asked for themselves are different. This is a general classification, not legal advice.
For an AI phone assistant, the GDPR applies as it does to any service provider that processes customer data. With ScaleTalk, the data is stored on servers in Frankfurt and stays in the EU, you get a data processing agreement under Art. 28 GDPR, and calls are only recorded with consent. In addition, there is the disclosure obligation from Article 50 of the AI Act.
Yes. Everything runs via call forwarding on your number. You decide when Max takes over: always, as soon as all lines are busy, when nobody picks up after a few rings, or after hours.
Yes, if your system has an interface. This applies, for example, to Keyloop, Loco-Soft, WERBAS, incadea and VaudisX, plus workshop planners like 1-wtp and repareo. Max then recognizes customer and vehicle, sees the order status and enters appointments directly. Without an integration, appointments land in your Google or Outlook calendar and call logs arrive by email. Which route fits your setup, we clarify in the needs analysis.
Yes. Each location keeps its number, Max knows which branch was called and warm-transfers to service reception, sales or parts. Warm means: he briefly summarizes the request and only then connects. There is no limit on how many calls can run at the same time.
