AI receptionist vs telephone answering service
A comparison written by a vendor, including the cases where you should buy the human service instead of ours. If you have been searching for a virtual receptionist, this is the same decision under a different name.
Short answer. A telephone answering service employs people and usually charges per minute or per call, with out of hours costing more. An AI receptionist answers automatically at a flat monthly price, so nights and weekends cost the same as Tuesday afternoon. Humans win on judgement and difficult conversations. AI wins on availability, cost predictability and capturing details accurately every time.
How the two are actually priced
This is where most of the confusion sits. The two models are not comparable line for line, because one scales with minutes and the other does not.
| Telephone answering service | AI receptionist (Enquiry 360) | |
|---|---|---|
| Typical charging model | Monthly retainer plus per minute or per call | Flat monthly price for a call allowance |
| Cost of an out of hours call | Commonly charged at a premium | The same as any other call |
| Cost when you have a busy month | Rises with usage | Predictable until you exceed the tier |
| Published entry price | Varies, ask each provider | £99 + VAT a month, 100 answered calls |
| Other costs | Setup or contract minimums may apply | Your own Microsoft usage, billed to you by Microsoft |
We deliberately do not publish competitors' prices here. They change, they vary by contract, and quoting them would be unreliable. Ask each provider for their current rate per minute and their out of hours rate, then compare against a flat monthly figure at your real call volume.
What you actually receive after the call
This difference gets overlooked and it matters more than the price. An answering service gives you a message: who rang, roughly what about, and a number to ring back. Enquiry 360 gives you a structured record in a real business system, with each detail in its own field, which means it can be searched, reported on, routed by type, and counted.
If all you need is "someone rang, call them back", a message is fine. If you want to know how many enquiries came in last month, how many arrived out of hours, what they were about, and which ones never got followed up, you need records rather than messages.
What an AI answering service actually is
An AI answering service is software that answers your phone, on your own number, at any hour, and takes the enquiry the way a person would: asking your questions, in your order, and writing down what was said. The same thing is sold as an AI receptionist, an AI phone answering service and an AI call answering service, and the label tells you almost nothing. What separates one from another is whether you get back a message or a record, and whose system it lands in.
Is an AI receptionist the same as a virtual receptionist?
Same question, different vintage of the words, and Enquiry 360 is sold as both. A virtual receptionist has traditionally meant a person, off-site, answering in your name. An AI virtual receptionist answers the same calls without the person, and the same product is called a voicebot, a virtual agent or an AI phone answering service depending on who is selling it. The comparison below applies to all of them, because what you are really choosing between is a human taking a message and software running your process.
Where a human answering service genuinely wins
We would rather say this plainly than have you discover it later:
- Emotionally difficult calls. Bereavement, distress, safeguarding. A person should take those.
- Highly variable conversations that need judgement rather than accurate capture.
- Consultative selling on the phone, where the job is to persuade rather than to record.
- Callers who simply refuse to speak to a machine. Some do, and no amount of natural conversation changes that.
Where the AI wins
- It runs the process you already have. The same process your team follows when they answer is the one the phone follows when they cannot, and both land in the same record.
- Consistency. It asks question forty of your process exactly as written, on the thousandth call as on the first.
- Languages. 65+ of them, in a native voice, without hiring anybody.
- Never engaged, never queueing. Callers who ring at the same moment get separate conversations.
- Out of hours. No staffing cost per hour means three in the morning costs the same as three in the afternoon. Most missed calls arrive when nobody is there.
- Structured data instead of messages, in a system you own.
What about where the data goes?
Worth asking of any provider, human or AI, because both hold your callers' personal data. Most AI receptionists store it on their own platform. Enquiry 360 runs inside your own Microsoft tenant, on Power Apps and Microsoft Dataverse, so the records sit in your environment rather than a vendor's. We wrote that up separately: where your call data actually goes.
The quickest way to decide
Ring both. Ring an answering service and see how long it takes and what you get back. Then ring ours and do the same. It takes about four minutes and it will tell you more than any comparison page, including this one.

Frequently asked
Do AI receptionists work out of hours?
Yes, and it is usually the strongest argument for one. There is no staffing cost per hour, so nights and weekends cost the same as weekdays.
When is a human answering service the better choice?
When calls are emotionally difficult, highly variable, or need judgement and persuasion rather than accurate capture.
Can an AI receptionist transfer calls to a person?
Enquiry 360 can put a caller through to a number you set, and route different enquiry types to different destinations. It never claims a transfer it cannot make.
Will my callers know it is not a person?
Yes. It says so at the start of the call. We think that is both the legal and the decent thing to do.
Can I keep my existing number?
Yes. You keep your number and forward calls when you cannot answer: after hours, when you are on a job, or all the time.
What is the difference between an AI answering service and a phone answering service?
A phone answering service is people, and what you get is a message. Quality moves with who is on shift and how busy they are. An AI answering service runs your actual process: the same questions in the same order every time, validated as they are given, and written into your own system as a structured record rather than a note for somebody to retype later.
Is an AI answering service cheaper for a small business?
Usually, and the reason is the shape of the pricing rather than the headline. A human service charges for time, so a busy month costs more than a quiet one. This is a flat monthly cost from £99 plus VAT, so the hundredth call in a month costs what the first one did. Worth comparing on your busiest month rather than your average.
Is a virtual receptionist the same as an AI answering service?
Not quite. A virtual receptionist is usually a person working remotely, answering your calls alongside calls for other businesses. An AI answering service is software answering on your own number at any hour, on a flat monthly price with a call allowance rather than a charge per minute. Enquiry 360 is the second, and either way what matters is that the enquiry lands in your own system rather than on a platform somebody else owns.
