This is what you know as a plumbing & heating installer
A plumber gets 15–25 calls a day — from "small drip" to "water rising in the basement". The AI triages: urgent → calls you straight away. Routine → books a time itself.
You have 50 customers with an annual boiler service. Who are we visiting in April? The list lives in your head — and some customers move to the competitor because you forget to call.
You arrive at a faulty circulation pump — the pump isn't in the van. Half an hour of extra driving. The AI gathers the material needs from the call and sends the order to Sanistål or Solar.
Hear what happens when you can’t pick up the phone yourself
You take the calls you can. But when your hands are full, the AI takes over: it answers in Danish, understands what plumbing & heating installers get called about, books the time and sends you a summary. You stay in control — it’s your backup, not your replacement.
- Urgent cases are forwarded to you straight away
- Books directly in your calendar — only in free slots
- You get a summary by SMS, so you always know what was agreed
“There’s water in my basement — it’s pouring out under the cistern!”
You get it all as a summary — and can always take over yourself.
How Online Erhverv helps plumbing & heating installers
When the customer says "water in the basement", the AI understands it's urgent and calls you. When it's "the boiler's a bit noisy", it books a planned time. You sleep soundly at night.
Load your existing service customers. The system sends the message itself: "Hi Hansen, it's about time for your annual boiler service — book a slot here." Repeat-visit rates climb 30–50%.
The AI gathers material needs from site visits — pumps, valves, pipes, fittings. The order can be sent straight to Sanistål, Solar or Brødrene Dahl with one click.
What the day looks like as a plumbing & heating installer — before and after
- An emergency call at 11pm goes to voicemail — the customer calls someone else
- You drive 7 service visits and write every invoice on Sunday night
- Parts from the van never make it onto the invoice — that's your margin gone

- You have no idea whether Tuesday's basement job actually made a profit
- The AI triages emergency calls and rings you if it's urgent — you lose none
- The per-visit invoice is ready with hours and parts the moment the job closes
- You snap the receipt at the till — it's posted before you're back in the van
- Service contracts generate the annual service automatically and book a time
- You see the contribution margin on every visit — even the small urgent ones

Frederik will happily show you what it would look like for your business — free, no sales talk.
Can the AI tell the difference between urgent and routine plumbing jobs?
Yes. The AI is trained on Danish plumbing scenarios and understands that "water in the basement", "no heating in winter" or "no hot water" is urgent and calls you directly. While "small drip" or "the boiler's scaling up" is booked as planned.
Can you send orders to Sanistål, Solar or Brødrene Dahl?
Yes. The AI gathers materials from site visits and your notes, and you can send the order with one click. We have deep links to Sanistål, Solar, Brødrene Dahl and Brink VVS.
How does the system handle service contracts for district heating and natural gas?
We create a contract template per customer type (district heating, natural gas, ground-source heating, heat pump). The AI automatically messages the customer 30 days before the annual service is due and lets them book it themselves.
Can I integrate with Minuba or Ordrestyring?
Yes. We offer both CSV export and direct integration with Minuba, Ordrestyring and Smartday. You can also use our own system if you want everything in one place.
What happens if a customer calls from a site crew that doesn't know the AI?
The AI always introduces itself as "the AI receptionist at {your company name}". If the customer wants to speak to you directly, it transfers the call. If you're busy, the AI takes a message and texts you.
What does a plan cost for a plumbing business with 4 journeymen?
The Pro plan (1,995 DKK/month) covers 5 users, unlimited bookings, 200 AI calls/month and the full service-contract module. Most plumbing firms with 3–8 journeymen choose Pro.
Do I get the AI phone 24/7 or only on working days?
The AI answers 24/7 in Danish. You set the rules yourself — e.g. "urgent → call me 06–22, routine → book for the next day, weekend → emergency calls only". We set it up with you during onboarding.
