Comparison
Three products priced in three different units. Here they are on the same volume, in Australian dollars, with what the rate cards leave out.
All three of these get sold as the answer to the same sentence, which is that you cannot get to the phone. They are not the same product, they are not priced in the same unit, and comparing them without doing the conversion is how businesses end up paying for the wrong one.
01
One hundred missed calls in a month, all inside business hours, all from published Australian rate cards where an Australian rate card exists.
| Option | Published price | Works out at |
|---|---|---|
| Text-back, messages only | About $29 a month | About 29c a call, four SMS each |
| Text-back, all in | $79 to $179 a month | Messages plus a platform, and your time on the replies |
| Human, message taking | $200 a month for 100 calls | $2.00 a call |
| Human, receptionist and transfer | $345 a month for 100 calls | $3.45 a call |
| Human, appointment booking | $515 a month for 200 minutes | About $2.58 a minute |
| AI receptionist, packaged in Australia | $149 for 100 minutes to $499 for 700 | About $1.49 down to 71c a minute, plus setup |
| AI receptionist, built on a platform | From about 7c a minute, in US dollars | Plus telephony, plus somebody to build it |
Australian dollars excluding GST, from vendors' own published pricing pages in August 2026, except the platform row which publishes in US dollars. Per-call and per-minute figures are the published fee divided by the published inclusion.
Read that table twice, because the interesting comparison is not the one people make. Text-back against a human answering service is a factor of seven on the messages alone, and much less once you add the platform. AI against a human is closer than the marketing suggests once minutes are converted into calls: a three minute conversation on a packaged Australian AI plan lands between about $2.14 and $4.47, which is the same neighbourhood as a human receptionist taking the call.
02
This is the single most common error in these comparisons. Australian answering services charge extra outside roughly 8am to 6pm on weekdays and on public holidays: in the order of 60 cents a call on message taking, a dollar a call on the receptionist tiers, and 80 cents a minute on the booking tiers. If the reason you are shopping is that you miss calls at night, that surcharge applies to most of your volume, not a slice of it.
The very low per-minute figures come from developer platforms, and some of them are a platform fee with the speech recognition, the language model, the voice and the telephony passed through at cost on top. One platform is transparent about charging five cents a minute and billing everything else separately. Another quotes a range from seven to thirty-one cents a minute depending on which language model you choose, which is a fourfold swing decided by a dropdown. Australian packaged products bundle all of that and charge more, and one of them publishes a setup fee from $990.
The messages are cents. What text-back actually costs you is somebody watching the replies. If nobody does, you have automated the act of raising a customer's hopes. Budget the attention, not the SMS.
03
| Good at | Bad at | |
|---|---|---|
| Text-back | Volume, cost, keeping a lead warm, after hours | Anything urgent, anyone distressed, anyone who does not text |
| Human answering | Distress, nuance, complaints, complicated callers | Cost at volume, knowing your business, after-hours pricing |
| AI receptionist | Answering instantly at any hour, asking the same five questions, booking | Edge cases, accents in a noisy ute, anything it was not scripted for |
The honest summary is that a human answering service is the only one of the three that can handle a person who is upset, and an AI receptionist is the only one of the three that can answer instantly at 2am without a surcharge. Text-back is the cheapest of the three and does the least.
04
This part gets skipped entirely in overseas comparisons, and it matters because the three options sit under different Australian laws.
05
| If you are | Start with | Because |
|---|---|---|
| A sole trader tradie | Text-back | Low job value, high call volume, and you can read a text between jobs |
| A clinic with a full diary | AI or a booking service | The value is in the booking, and a message in an inbox is not one |
| An aged care or NDIS provider | Human answering | The caller is often distressed and the call is often about a person |
| A professional services firm | Human receptionist plus text-back | Few calls, high value, and the first impression is the product |
A starting point for the first conversation, not a rule. Plenty of businesses sensibly run two of the three.
06
We build the agent and the system it sits on: something that answers in under two minutes at any hour, asks your qualifying questions, books into a real diary, and hands over to a human the moment it should. It is part of a build from $2,100 plus GST as a one-off rather than a subscription with our name on it, and the accounts are in your name so you can leave with the lot.
We will also tell you not to buy it, and often do. If you miss five calls a week and each job is worth a couple of hundred dollars, an AI receptionist is an expensive answer to a cheap problem and text-back is the right call. If your callers are frightened or grieving, buy a human. And if the enquiries you already have are sitting unanswered in four different apps, fix that first, because none of these three will help if the answer still lands somewhere nobody looks.

Where these numbers come from
Every figure above is either the reader's own arithmetic or one of these. Where a range could not be verified against a primary source, the post says so in the sentence rather than pretending to a decimal place.

Websites
There is no official figure for what a website costs in Australia, only ranges published by people selling them. Here are the four bands, what moves the price inside each, the real ongoing costs, and what the ATO lets you deduct.
Hiring
Award rate, twelve per cent super, leave loading, workers comp, payroll tax and the cost of finding them. A part-time admin on $29.45 an hour works out closer to $40 for every hour actually worked, and here is the arithmetic.
Systems
Texting back a missed call costs about seven cents a message at Australian rates. The real cost is the platform, and the real risks are the Spam Act, the new SMS Sender ID Register, and the fact that most Australian landlines cannot send a text at all.
