Lead qualification · Germany

How does an AI agent qualify leads for a business in Germany?

It asks the questions you write into its prompt, in German, on the phone or on WhatsApp, then books a visit, schedules a callback or hands the lead to a person. Below are three conversations from Dresden, Munich and Hamburg, the questions that matter when buying and renovating in Germany, and the strict rules for following up a lead by phone.

Example 1 · Inbound call

Can the agent qualify a homeowner who rings about a rooftop solar system?

Yes. The caller owns a house, has an east-west roof and wants to know whether a battery is worth it. The agent asks the questions an installer needs before a visit and books a survey slot. The call is held in German and shown here in English.

  • Name: Jens Albrecht
  • Need: Rooftop solar with battery, house in Dresden-Klotzsche
  • Owner: Yes
  • Roof: Tiled, about 20 years, east-west
  • Use: About 4,500 kWh a year, car next spring
  • Timing: Before the end of the year
Solar installer · Dresden Inbound call
CallerGood morning. I would like a solar system for our house in Dresden-Klotzsche. Do you do that?
AgentGood morning, yes. I'm the automated assistant of Sonnenwerk Elbtal. Is the house yours, and how old is the roof?
CallerWe own it. The roof is tiled, about twenty years old, east and west sides.
AgentThank you. Roughly how much electricity do you use a year, and do you charge a car at home or plan to?
CallerAbout 4,500 kilowatt hours. An electric car is coming next spring.
AgentGood. Would you like a battery included in the quote? And do you want to start this year or next?
CallerWith a battery. Ideally before the end of the year.
AgentThen a survey is the next step. Can the technician come on Thursday at 16:00 or Friday at 10:00?
Qualified · hot · roof survey booked Thursday 16:00
Private school · Munich Outbound follow-up call
AgentGood evening, this is the automated assistant of the Isar International School, calling for Ms Hartmann. On our website you asked us to call you about admission. Is now a good moment? You can ask me to stop calling at any time.
LeadYes, I have a few minutes.
AgentThank you. Which year would your child start, and in which grade?
LeadNext September, grade 5. But we only decide after the half-year report, in February.
AgentI understand. Many families do. Would you like to book a visit evening before then, so you can compare?
LeadNot yet. Please call again in February.
AgentOf course. I'll call on Tuesday 9 February at 17:30. If you would rather not be called, tell me now and I will remove your number.
LeadThat's fine, thank you.
Not ready yet · warm · callback scheduled Tuesday 9 February, 17:30

Example 2 · Outbound follow-up call

Can the agent follow up a parent who ticked "please call me" and accept a "not now"?

Yes. The parent filled in the school's form and ticked a separate box asking for a phone call about admission. The agent says who is calling and why, offers to stop, asks what the admission team needs and, when told the family decides in February, schedules a callback instead of pushing.

  • Parent: Ms Hartmann
  • Child: Grade 5, start next September
  • Decision: After the half-year report, in February
  • Consent: Ticked the box asking for a phone call on the form
  • Contact: Phone, evenings

Example 3 · WhatsApp

Can the agent qualify a renovation quote request on WhatsApp?

Yes. The customer wrote first from the firm's website button, so the agent can reply in the open conversation. It asks about the flat, ownership, the landlord's consent and the date, then books a site visit. The chat is in German and shown here in English.

  • Need: New bathroom, old building, Eimsbüttel
  • Owner: Yes; owners' association not yet asked
  • Floor: Second, no lift, built around 1910
  • Budget: About 25,000 euros
  • Start: Spring
Bathroom renovation firm · Hamburg-Eimsbüttel WhatsApp
CustomerHello, I would like a quote for a new bathroom in an old building in Eimsbüttel.
AgentHello, I'm the assistant of Badbau Nord. Happy to help. Do you own the flat, or do you rent it?
CustomerI own it. Second floor, no lift, built around 1910.
AgentThank you. For a building like that the owners' association may need to agree to some work. Is there one, and have you asked?
CustomerYes, there is one. Not asked yet, it's about the pipes in the wall.
AgentOur technician will explain what needs approval. Roughly what budget do you have, and when would you like to start?
CustomerAbout 25,000 euros. Spring.
AgentUnderstood. Can he visit on Monday 9 November at 17:00, or Wednesday 11 at 8:30? Photos of the bathroom sent here before then will help.

Questions to ask

What should the agent ask a lead in Germany?

You write these into the agent's prompt, in your own words and in your customers' language.

QuestionWhy it matters here
Do you own the property, and is there an owners' association (WEG) or a landlord who has to agree?In Germany, work on a flat in a shared building can need the owners' association, and a tenant needs the landlord. Asking early avoids a site visit for a job that cannot go ahead.
Which postcode or district, and what kind of building?Travel time decides what a Handwerksbetrieb can take on, and an old building (Altbau) is a different job from a new one. A lead outside your area should be told so early.
How large is the job, and what budget range do you have in mind?A range is enough to band the lead. German customers often compare several offers, so the budget and the date tell you how quickly to move.
When do you want to start, and is there a fixed date such as the end of the year or the start of a school year?Many trades have waiting lists of weeks or months, so a lead who needs work soon belongs at the top and one who plans for spring can be given a later visit.
Who else decides: a partner, the landlord, the property manager or the school board?In German households and housing associations decisions are often shared. Knowing who decides tells you whether to book a visit now or send material first.
May we contact you by phone or WhatsApp about this, and when is best?Advertising calls need prior express consent in Germany, so a separate, dated yes to a phone call or a message is part of the qualification, not an extra.

Reading the outcome

Hot, warm or cold: what happens next.

The bands are the ones you describe in the prompt, then read off each call's outcome and transcript.

BandWhat it meansWhat you do next
HotOwner or authorised, budget and date fit, and they accepted a survey, visit or admission talk.Confirm the slot by message, send the address, and brief the person who will meet them. The bands are what you write into the agent's prompt, not a built-in score.
WarmReal interest but not ready: waiting for the owners' association, a school report, financing or a second offer.Let the agent schedule the callback the lead chose, and send a short message with what you offer meanwhile. Do not call before the agreed date.
ColdOutside your area or budget range, only browsing, or asked not to be contacted.Close politely with the information they asked for, add anyone who objected to your do-not-contact list at once, and do not contact them again.

The rules

What the rules say about following up a lead in Germany.

Consent, do-not-call lists, calling hours and recording are set by local law, and you are responsible for them.

Calling someone who filled in a web form

Section 7(2) no. 1 of the Unfair Competition Act (UWG) treats an advertising call to a consumer without their prior express consent, or to another market participant without at least their presumed consent, as an unreasonable nuisance in every case; no. 2 requires prior express consent for advertising with an automatic calling machine. Section 7a requires you to document a consumer's consent at the time it is given and keep the proof for five years from the consent and after each use, and the Bundesnetzagentur can fine an unlawful advertising call to a consumer up to 300,000 euros (section 20). The Bundesnetzagentur adds that consent is needed even for existing customers, can be withdrawn at any time, and counts in pre-printed terms only if it is clear which advertising and which company it covers; callers must show their number. A form with a separate, ticked box asking for a phone call is the strongest footing; keep the wording and the date. We could not verify whether a voice agent counts as an automatic calling machine, so plan on the stricter view. The product does not collect or check consent; it gives you a do-not-contact list you keep. Read the official text; not legal advice.

Following up on WhatsApp

Section 7(2) no. 2 UWG requires prior express consent for advertising by electronic mail, and the IHK guidance we read treats SMS and WhatsApp messages as covered by that term; section 7(3) has a narrow exception for e-mail to your own customers about similar products, with a clear way to object. We found no court ruling on WhatsApp specifically, so ask your adviser whether a given message counts as advertising. A lead who writes to you first can be answered in that conversation. Writing first to someone who only filled in a form is different: ask on the form whether they want WhatsApp, and outside the 24-hour window use an approved template. Read the official text; not legal advice.

Recording, hours and data

Section 201 of the Criminal Code punishes recording another person's non-public spoken word without authorisation with up to three years' imprisonment or a fine, so if you record, tell the person at the start and let them object. Recording is a per-agent switch, off by default, and the opening line is yours to write. The platform sets no calling window of its own; you set hours for each campaign on the called person's clock, and we found no statutory calling-hours rule in the texts we read, so ask your adviser. We support region deployments for enterprise customers. Calls are also processed partly in other countries under transfer safeguards. Read the official text; not legal advice.

Local notes

What is different in Germany.

  • Languages: voice agents speak German, English in American, British, Australian, Indian and other accents, and Turkish, Polish, Russian and many more. We claim German, not a regional variety, so we make no promise about an Austrian or Swiss accent. Choose a formal "Sie" in the instructions unless your brand is deliberately informal.
  • Channel: chat and WhatsApp replies run in 37 languages, German, English and Turkish among them. We found no reliable national figure for how many customers prefer WhatsApp for business, so ask your own customers which they like.
  • Timing: set calling hours on the called person's clock. Early evening suits parents and homeowners who work, and Sundays and public holidays differ by federal state, so check the calendar of the state you call. These are customs, not legal rules.
  • Numbers: use your own German number, imported from a Twilio, Telnyx or Plivo account you hold; we do not sell German numbers, and Telnyx needs Germany switched on for outbound calls.

Questions

Common questions.

Can the agent call a lead who filled in my web form straight away?

+
Only if the form asked for it. Advertising calls to consumers need prior express consent under section 7 UWG, which you must document and keep for five years. A ticked box asking for a call is the safest case. Read the official text; not legal advice.

Is a voice agent an automatic calling machine under the UWG?

+
We could not verify it. If it is, prior express consent is needed even for business calls, so plan on that stricter view.

Can the agent qualify leads in Turkish or English?

+
Yes, on the phone and in chat. Voice agents speak German, English and Turkish, and chat and WhatsApp replies cover all three. Have a native speaker listen before you use a voice with customers.

Are there fixed calling hours in Germany?

+
We did not find a statutory calling-hours rule in the texts we read. The platform sets no window; you set hours for each campaign on the called person's clock.

Does the agent score the lead for me?

+
No. The bands are what you write into the agent's prompt, and you read them off the outcome. It captures the answers and a transcript, books a slot or schedules a callback.
