The plumber is under a sink when the phone rings at 11:30. It goes to voicemail. The caller hears the beep, decides this can wait, and rings the next company on the list instead. When the plumber checks voicemail in the afternoon, there is no message. Just a missed call from an unknown number.
Voicemail did exactly what it is meant to do. It just wasn't what the customer needed.
What sets them apart
Voicemail records. It cannot ask, answer or judge. Nothing happens until someone listens to the message and calls back – if there is a message, and a number to call.
An AI answering service picks up instead, with a voice agent that holds a real conversation:
- It asks what the call is about. The address, what happened, how urgent it is. The caller doesn't need to know what is important to mention.
- It answers what it can. Opening hours, prices, whether you take jobs in a particular area.
- It judges urgency by your rules. A burst pipe on a Saturday evening shouldn't wait until Monday. The agent can alert whoever is on call.
- It books. If you have a calendar, the caller can get a slot during the call.
- It summarises. Instead of an audio clip to listen to, you get a written summary with name, number and the matter at hand.
The difference isn't that one is modern and the other old. It is that the caller gets an answer while they are still on the phone.
Count your own voicemail first
Before you change anything, spend a week counting. How many missed calls did you get, and how many messages were left? Many people who reach voicemail hang up without saying a word. The gap between those two numbers is the customers you don't know you've lost.
Then do a rough calculation:
- Missed calls without a message per month. From your own call log.
- The share of those that would have become a job. Be careful here. Not every call is a new customer.
- What a job is worth on average. What you invoice, not just the margin.
As a worked example, not a statistic: say you miss 40 calls a month without a message, one in ten would have become a job, and a job is worth NOK 4,000 on average. That is NOK 16,000 a month going to someone else. Compare that with what an AI answering service costs for the same volume – at Threll it starts at NOK 699 a month plus NOK 4 a minute, and 40 three-minute calls come to 120 minutes. Swap in your own numbers.
