Phone answering services have been around for decades. You pay a call centre to answer calls in your business's name, take a message, and pass it on. It's a real service that solves a real problem — and it's worth comparing honestly to what AI receptionists do, because they're not the same thing.
What a phone answering service actually gives you
A phone answering service provides a human on the other end of the line when a customer calls. They answer using your business name, follow a script, take a message or handle basic queries, and either patch calls through or send you a notification.
For businesses where phone calls are the primary inbound channel — and where the customer expects to speak to a person — this can be valuable. The human element matters in certain contexts.
The limitations are practical. Answering services work on phone calls. They don't handle website enquiries, after-hours chat conversations, or the growing share of customers who would rather message than call. They also charge per call or per minute, so costs scale with volume in a way that can become difficult to predict.
What an AI receptionist actually gives you
An AI receptionist handles enquiries that come through your website — chat conversations that start when someone visits your site and has a question. It's available at all hours, responds instantly, and scales to as many simultaneous conversations as needed without additional cost per interaction.
It handles the research and pre-booking phase of the customer journey well: "Do you cover my area?", "What's your pricing?", "How long does it take?", "Can I book for next Saturday?" These are the questions that precede a booking decision, and they're the ones that most commonly arrive when no one is available to answer them.
The actual difference in customer behaviour
Younger customers — and an increasing proportion of all customers — don't call first. They check your website. If the website can answer their questions, they book. If it can't, they look at the next option on Google.
A phone answering service doesn't help this customer at all. If they never pick up the phone, having someone to answer it doesn't change the outcome.
An AI receptionist doesn't help the customer who picks up the phone expecting to speak to a human. If your inbound is primarily calls, an AI chat widget on your site won't capture them.
Most local service businesses get enquiries through both channels. The question is where your gap is.
Cost comparison
Phone answering services typically charge a monthly base fee plus per-call or per-minute rates. Costs vary considerably depending on the provider and call volume, but for a business receiving a moderate number of calls, monthly fees can add up quickly — especially during busy periods.
AI receptionists generally charge a flat monthly subscription. Costs don't increase with enquiry volume, which makes budgeting predictable and makes high-volume periods less expensive to manage.
The handoff question
One area where phone answering services have a clear advantage: complex or sensitive calls. A trained operator can navigate a difficult conversation, sense distress, and escalate appropriately. A well-configured AI receptionist will recognise when it can't help and prompt the customer to call or leave details for a callback — but it doesn't have the emotional range a human does.
For businesses that routinely handle sensitive calls — mental health, legal matters, emergency services — a human answering service is the appropriate tool. For businesses where enquiries are primarily logistical — "can you fit me in Thursday?", "do you do X?" — the AI does the job faster and at lower cost.
Can you use both?
Yes, and some businesses do. An AI receptionist handles website chat around the clock. A phone answering service handles inbound calls during hours when the team is occupied. They serve different channels without overlapping.
Whether both are justified depends on your call volume and the share of enquiries that arrive through each channel. For a lot of local businesses, the website enquiry channel is under-served and the phone channel is already handled adequately — meaning the AI receptionist addresses the actual gap.
The honest summary
Phone answering services and AI receptionists solve different problems. One handles phone calls with a human voice. The other handles website conversations instantly and at scale. Neither is universally better — the right answer depends on how your customers actually try to reach you.
If your website enquiries are being lost after hours because no one's available to respond, an AI receptionist addresses that directly. If your phones are going unanswered, an answering service is the fix. If both are true, the order to address them in usually comes down to where you're losing the most business.
