The appointment was at nine. He didn't come, and the chair stood empty for an hour.
Threll calls your customers and reminds them of the appointment, the due date or the site visit. It confirms, books a new time if it doesn't suit, and takes the payment on the call. You set it up yourself in the console in an afternoon – with help from us if you want it.

The reminder nobody answered
A no-show is an hour you can't sell twice. It sits in the calendar as confirmed right up until nine, and by then it's too late to fill. The same goes for the invoice falling due on Friday: it doesn't get paid because an email about it exists.
The SMS gets read, not answered
It disappears between delivery notices and campaigns. And even when it is read, you still don't know whether the customer is coming.
The email lands at the bottom
The chaser is read a week late at best. Nobody gets to ask why the invoice hasn't been paid, or whether it arrived at all.
Calling round yourself takes all morning
Two hundred appointments a month is two hundred calls somebody in the office has to fit in around everything else. The important ones get called. The rest don't.
None of the three gives you the answer you actually need: are you coming?
Run the numbers with your own figures
It takes just three numbers. How many appointments and due dates you have in a month, how many of them fall through because nobody showed up or paid on time, and what one of them is worth.
You're losing roughly 75,000 kr a month across 30 appointments. Threll Start costs 699 kr.
We don't know your numbers. Plenty of firms know how many didn't turn up, but not how many of those would have said so if somebody had called – and that's the whole point. The test week gives you the actual figure, whether or not you pick us afterwards.
Live in a single afternoon
Five steps you do yourself in the console. You connect the calendar or upload the list, and need no integration to get going. If you get stuck, we help for free.
Full control of every call
Every call with summary, outcome and recording. You run it all yourself – see what your threll said, and close the gaps as you read.
What the agent actually does
Calls in real Norwegian – and 70 more languages
Natural Norwegian speech that handles dialect and interruptions. If the customer speaks English, Polish or Lithuanian, the agent switches mid-call – and back again.
Books a new time on the call
If the time doesn't suit, the agent offers the next free slots and moves the appointment there and then. The calendar is updated before the call ends.
Had forgotten the appointment. Moved to Thursday 14:00 with Kari. Paid the overdue invoice by Vipps on the call.
Transcript, summary and sentiment
The whole call in writing, a five-line summary, and a signal on whether the customer minded being called.
Sorts the outcome of every attempt
You define what happens next. Confirmed goes back into the calendar. No answer is retried. Wants to cancel goes to the office.
Calls the whole list, not just the important ones
Two hundred or two thousand reminders a month costs the same in time: none. The agent works through the list at the agreed moment and retries by your rules.
Captures what you need to know
Are you coming, does the time suit, did you get the invoice, do you need a new payment link. Fixed questions, the same every time – and the answers land structured in the log.
Transfers or notifies
If the customer wants to speak to someone, the agent transfers straight away within opening hours. Otherwise the office gets an SMS and an email with a summary.
Calls many at once
Tomorrow's entire list can be called in one window this afternoon. The agent takes them in parallel, not one after another.
Payment and authentication with Vipps
The agent sends a Vipps request during the call – the customer pays the overdue invoice while you're talking, instead of promising to do it later.
This is how it sounds the day before the appointment
A real call from a standard setup. Listen to it – or read it, if you're in the car with someone else.
Hello, this is an AI assistant calling from the dental clinic. I'm calling about your appointment tomorrow at nine – does that still work?
Oh, tomorrow at nine? I'd completely forgotten. No, I've got a meeting then.
We'll sort that out. I have Thursday at ten or Friday at half past one free, both with Kari.
Thursday at ten is fine.
Then I'll move you to Thursday at ten with Kari. Confirmation is coming by SMS now.
Good. And that bill from last time, I haven't paid it.
I can see it here, 2,480 kroner, due on Friday. Shall I send a Vipps request now so it's out of the way?
Yes, do that.
Sent. So you're down for Thursday at ten, and the bill is in Vipps. Have a good day.
Need help getting started?
Book a meeting with us and we will help you get going.

Built for the firms that lose money on an empty slot
Dental and GP practicesA no-show is an hour that can't be sold a second time.
Salons and beautySaturday is full long before it arrives. One drop-out costs the whole slot.
Physiotherapy and chiropracticTreatment courses fall away if nobody reminds people of the next session.
Vets and animal clinicsVaccinations and check-ups fall due on a date, and are forgotten on a date.
Car workshopsMOTs and drop-offs have to be confirmed, or the ramp stands idle.
Tradespeople and site visitsA wasted trip is two hours in the van because the customer wasn't home.
Accounting and collectionsA call before the due date gets more invoices paid than a chaser after it.
Lettings and propertyViewings, contract renewals and rent all fall due on fixed dates.
Courses and trainingPeople who register and don't turn up block seats somebody else wanted.

Self-serve setup
Create an account, configure the agent and set up forwarding yourself – in an afternoon. If you need help along the way, it costs nothing.
Create accountDo compare
A human answering service typically charges 25–50 NOK per answered call. A lost customer costs you the whole sale.
Run the numbersWhat your customer hears, and what you need to be able to answer
Five questions you will get – from a customer, a board chair or a procurement officer. The answers are the same on every plan.
The agent says it is an AI assistant
It happens in the first sentence. It is a requirement under the EU AI Act – and it is also what makes customers accept it.
Norwegian and European data storage
Call data is processed within the EEA. A data processing agreement is standard, not an add-on.
Telephony on Telenor SIP infrastructure
The same network as the rest of Norwegian business telephony. No detour across the public internet.
You own the data
Export or delete whenever you want. You set the retention period yourself.
On-prem and sovereign hosting exist
For those who must have it. Most firms in this segment don't need it – tell us if you do.
Yes, and they're told in the first sentence – the agent says so before it says what it's calling about. Our experience is that people accept it when the call is about their own appointment and they actually get it moved.
A reminder about an appointment the customer made themselves, or an invoice falling due, is not marketing – opt-outs from cold calling don't cover those calls. You control who is on the list, and the agent sells nothing unless you ask it to. If you do want it to sell, the ordinary rules apply and you have to check the do-not-call register as usual.
You set the number of attempts and when they happen. The default is one retry the next day, then an SMS with a link to confirm themselves. Every attempt sits in the log with its outcome.
Yes, once you connect it. The agent sees which slots are free, moves the appointment on the call and sends confirmation. Without a connection it notes the preferred time and sends it to the office.
Yes, with Vipps on the call. The customer gets the request while you're talking and pays before the call ends, instead of promising to do it later.
No. Outbound calls are placed from your own number, so the customer sees your firm on the display. You keep your number, your operator and your setup.
You do it yourself: connecting the calendar or uploading the list takes ten minutes, and writing what the agent should say and ask typically takes half an hour in the console. If you'd like one of us on a screen share, it costs nothing.
Nothing. You create the account yourself, let the agent call one week of appointments, and have your own figures afterwards.
