This is what you know as a sheet-metal worker

Emergency jobs lost on the roof
You can't answer the phone up on the roof

With both hands on the gutter and four metres up, the phone is the last thing you reach for. The emergency leak calls — which are pure revenue — ring on to the next contractor.

6-9 hours/week saved
Quoting roofing and zinc work takes time

Flashings, gutters and zinc roofs have to be measured and priced on both metal and hours. You measure by day and price by night. The AI builds the draft from your notes.

Metal prices swing — you price it wrong

Zinc and copper move in price, and it's easy to sell too cheaply. The AI's pricing brain remembers your typical prices and suggests the materials from the job.

The AI phone — your backup

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 sheet-metal workers 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

How Online Erhverv helps sheet-metal workers

An AI phone that triages emergency vs. planned

The customer calls, the AI answers in Danish, works out whether it's a leaking gutter that can't wait or a planned zinc job, and either calls you straight away or books a time.

Photo documentation on the job

Take before/during/after photos up on the roof — they're collected on the job, ready for the customer, the site manager or the insurer.

Quotes and invoices follow the job

The AI drafts the quote from your measuring notes, with metal and hours. On acceptance it becomes an invoice with VAT and your account number.

FAQ

Frequently asked questions

The questions sheet-metal workers ask most before getting started. Missing yours? Call or write — you’ll talk to a real person who knows the trade.

Still unsure?

Frederik will happily show you what it would look like for your business — free, no sales talk.

Can the AI phone understand sheet-metal terms like flashing, valley gutter and steel roof?

Yes. The AI is trained on Danish sheet-metal and roofing language and can note the metal type (zinc, copper, steel), the type of job and the measurements, and ask whether it's urgent (a leak) or planned.

Can the AI handle emergency leak calls while I'm on the roof?

Yes. When you can't take it yourself, the AI judges whether it's urgent — for instance a leaking gutter in the rain — and calls you straight away. Planned jobs it books into the calendar.

Does the system help with documentation for insurers and site management?

Yes. Before/during/after photos and notes are collected on the job, and QA reports can be signed digitally. You have the documentation ready whenever you're asked for it.

Does the system help me avoid selling too cheaply when metal prices swing?

The AI's pricing brain learns your sales prices from accepted quotes and suggests the price next time. You see the contribution margin per job in real time and get a warning if the margin drops too low.

Can you send invoices to Dinero, Billy or e-conomic?

Yes, via a direct API — entries are posted once you approve them. If you use a system without a public API, we send the document by email. We are not an accounting system ourselves.

Do I keep my phone number?

Yes. We set up call forwarding so calls go to the AI when you're on the roof, and straight to you when you're free.

What does it cost for a sheet-metal worker?

The Solo plan (995 DKK/month) covers booking, quotes, invoicing and 200 SMS/month. The AI phone is an add-on at +149 DKK/month (50 calls) — particularly relevant given the emergency calls from up high. Firms with employees choose Pro (1,995 DKK/month) with the AI phone included. 90 days free.
