Online ErhvervAI for tradespeople who would rather be on site
The AI takes the calls you can’t get to, drafts quotes from your own prices and reads your receipts. You approve quotes and invoices before they reach the customer. Jobs, hours and payroll sit in the same app, and the invoice is booked in e-conomic, Dinero or Billy.

Several trades in one firm? Software for tradespeople with many kinds of jobs
What the AI does for you
The AI does the groundwork across the app. It never sends a quote or an invoice by itself. You see it first, edit it and press send.
The phone gets answered, even when you’re up a ladder
Calls you can’t take go to the AI phone. It answers in Danish with your company name, writes down what the customer wants and texts them a booking link. You get a short summary, and if it’s urgent, you get an SMS straight away.
- Your number
- You keep it and forward the calls you don’t take
- Price
- Add-on at 500 DKK/mo with 100 calls a month.
- The trial
- Try the AI phone with 25 free calls during the trial.
Draft quotes from speech, text or a photo
Say the job, write it, or take a photo. The AI suggests lines, materials and prices based on your earlier quotes and your item prices. You adjust it, and the customer signs on their phone.
- Your prices
- The draft is based on your own quotes and your item catalogue
- You decide
- Nothing is sent before you have seen it
- Signature
- The customer approves the quote on their phone
Receipts are read for you
Take a photo of the receipt, or let the wholesaler’s invoice arrive by email. Invoice number, date, VAT and item lines are read, and the lines land on the job, so they end up on the invoice.
- Photo or email
- Both routes end up in the same place
- On the job
- Materials count towards the job’s contribution margin
Suggested replies to your reviews
When a customer writes a review on Google, you get a suggested reply that you can edit before you send it.
- You reply
- The suggestion is only sent once you have approved it
The prices you usually charge
The app remembers what you usually charge for a material, so you don’t end up undercutting yourself.
- Before you send
- If a price is lower than you usually charge, the app tells you. You can always send anyway
Weekly report
A short summary of revenue and customers every week.
- Monday morning
- New jobs, accepted quotes and what was invoiced last week, in an email
The AI is a help, not an autopilot. You approve quotes and invoices before they go to the customer.
The whole app, from the call to the bookkeeping
The AI is part of one app that covers the whole workflow of a trades business.
- Quotes and customersQuotes with e-signature, change orders and customer records
- Jobs and calendarBoard, calendar, map, projects and rota

Figures from RenoByg
RenoByg is Lucass’s building firm. He is also a co-founder of Online Erhverv.
How the figures are measured
RenoByg is owned by Lucass, who is also a co-founder of Online Erhverv. The figures are RenoByg’s own from just over 5 months in the app (May to October 2026): 25 of 30 decided quotes won (decided = the customer has said yes or no; quotes that are still open don’t count) and a median of 1 day from quote sent to accepted. Quotes the customer said yes to outside the app are included.
What tradespeople ask
If your question isn’t here, call 93 94 12 06.
Does Online Erhverv work for my trade?
Yes, if you are a tradesperson. The app is made for carpenters, plumbers, electricians, painters, bricklayers, roofers, drainage contractors, landscapers, smiths, glaziers, joiners, floor layers, sheet metal workers, heat pump installers and pavers, and for firms with several trades. It is only for tradespeople.
Does the AI replace me on the phone?
No, it is your backup. You take the calls you can. The ones you can’t get to go to the AI phone: it answers with your company name, takes a message and texts the customer a booking link. You get a short summary, and for urgent jobs you get an SMS straight away.
Can I use my own accounting system?
The invoice is booked in e-conomic, Dinero or Billy once you have approved it. We are not an accounting program ourselves, so your accounts and your accountant carry on as today.
How long does it take to get started?
You can sign up and get going straight away. The AI can find your services in your earlier quotes, and customers, jobs and open quotes can be imported from a file. If you’d rather have help, you can book a call.
What does it cost?
500 DKK a month for the company and 250 DKK per extra person. Apprentices and young workers are free (up to 2 per company). Everything is included, the employee app, hours and payroll too. The AI phone is an add-on at 500 DKK a month. All prices are excl. VAT, there is no lock-in, and the first 90 days are free with no payment card. Try the AI phone with 25 free calls during the trial.
Can my crew use it too?
Yes. Your crew get their own app with the day’s jobs, hours, photos and messages, even without signal. You decide what each employee can see, and only approved hours go on to payroll.
