What an AI receptionist, a part-time receptionist and voicemail actually cost
By André Bergan, 2026-10-07
There are really three ways to handle the calls you can't get to on site: let them ring out, pay someone to answer, or get an AI receptionist to do it for you. People usually assume the order of cost runs voicemail, then a part-time receptionist, then an AI receptionist, cheapest to most expensive. When you actually do the sums it doesn't hold up. Here's what each one really costs a small South African business every month.
Doing nothing costs nothing, until it doesn't
Letting the phone ring out or go to voicemail has no invoice attached to it, so it feels free. It isn't. Every call that rings out and doesn't call back is an enquiry you already spent time or marketing money getting, gone to the next business that picked up.
I worked through the actual maths on this in an earlier post: a small business missing five calls a week, closing a quarter of the ones it does answer, on jobs worth R3,000 each, is quietly giving up close to R16,000 a month. That number moves a lot depending on your job value, so if you want your own figure rather than mine, our missed call calculator takes about a minute.
The point for this post is simpler: "free" only means free of an invoice. It is almost never free of lost work.
A part-time receptionist is cheaper than people think, and narrower than people think
Say you bring someone on for four hours a day, five days a week, just to answer the phone and take messages. At R70 an hour, that's roughly 87 hours a month, so about R6,000 before UIF, before the odd day they're sick or on leave, and before the time it takes you to train them on your prices, your service areas and which jobs you actually want to take. That's a rough number to illustrate the shape of it, not a market survey, your area and your rate will move it.
What that R6,000 buys you is business hours, Monday to Friday. It doesn't buy you evenings, it doesn't buy you Saturday mornings, and those are exactly the times homeowners have a spare minute to deal with a leaking geyser or a quote they've been putting off. It also doesn't buy you someone who already knows every job you've got on the go, unless you spend time keeping them updated.
A full-time receptionist fixes the hours problem and costs a lot more for it. Most small trades businesses I talk to aren't at the size where those sums work yet.
An AI receptionist, and what the invoice actually says
Hannah costs R1,999 a month for 100 included minutes, VAT excluded, no contract, cancel anytime. That's about R66 a day, whatever day of the week it is, because she doesn't take weekends or evenings off. If you go over your minutes, it's R6 a minute after that, rounded up, and you're never cut off mid-call because of it. It just shows up on the next invoice.
For context, a typical enquiry call, where Hannah asks what the job is, where it is and takes your caller's number, runs a few minutes. So 100 minutes covers a fair number of enquiries. If you're a high-volume business, look at your own call log before you assume it covers you.
What's included in the R1,999 that isn't in the part-time receptionist's R6,000: every hour of every day, no sick leave, and a website if you need one, built into the same price rather than a second quote. Instead of training someone, you fill in a setup form once with your services, your areas and your hours. If you're not happy within 30 days of your first payment, that first month is refunded in full, so trying it costs you a month rather than a decision you're stuck with.
Side by side
- Voicemail: no monthly cost, but you're carrying the full cost of every missed job, which is usually far more than any receptionist.
- Part-time receptionist: around R6,000 a month for business hours only, plus training time, plus whatever you lose outside those hours.
- AI receptionist: R1,999 a month for 100 minutes, covering every hour, with a website included and the first month refundable if it isn't working for you.
What surprised me when I first did these sums is the hours, more than the price. The AI receptionist is the only one of the three that covers evenings and weekends, which is when a lot of homeowners finally get round to phoning.
