The short answer
A do-it-yourself chatbot platform costs about R150 to R5,000 a month. An AI assistant built around your business costs from about R40,000 once, and then from a few hundred rand a month to run for a small business. The price depends mostly on how much it has to do.
Three ways to get one
There are three main routes. The figures are what South African providers publish, checked in October 2026.
| Route | Once-off | Every month |
|---|---|---|
| Set it up yourself on a chatbot platform | Your own time | About R150 to R5,000, plus WhatsApp's fees |
| Have an agency set one up | About R5,000 to R50,000 | About R1,500 to R8,000 |
| Have one built around your business | From about R40,000 | A few hundred rand to run, plus support from R4,000 a month if you want it |
Setting it up yourself
This is the cheapest way in, and it works well for menus and frequently asked questions. You build the flows yourself. Many platforms answer from buttons and keywords rather than reading what the customer actually asked, and the AI part is often an add-on at extra cost.
Having an agency set one up
Someone else builds the flows, usually on one of those same platforms. Prices vary a lot, and few South African agencies publish them, so get in writing what the monthly fee covers.
Having one built around your business
An assistant that answers from your own prices and policies, and checks with you when it isn't sure. It costs more up front. Custom builds we've seen priced in South Africa, ours included, start at about R40,000 and run well past R100,000 for bigger jobs. Ask who owns it, and whose accounts it runs on.
What you pay every month
An assistant has three running costs. With a platform or an agency, their monthly fee comes on top.
WhatsApp's own fees
Meta, which runs WhatsApp, charges per message. Since 1 October 2026, each business number gets 1,000 free replies a month inside the 24 hours after a customer messages you. After that, each reply costs about 16c. Messages you send first, like a booking confirmation, cost about 16c each, and promotions cost about 62c each.
Meta sets these in US dollars for South Africa, $0.0095 for a reply or a confirmation and $0.0379 for a promotion, and reviews them every quarter, so the rand figures move with the exchange rate. When a chat starts from a click-to-WhatsApp ad and you reply within 24 hours, its messages are free for up to 7 days.
The AI's fees
The AI is paid for the words it reads and writes. On our own WhatsApp assistant, each customer message costs about 10c to 55c in AI fees. The first message in a chat costs the most. A typical chat of four or five messages comes to about R1.
Hosting
The assistant needs somewhere to run. Ours runs on a cloud plan that costs about R80 a month ($5), and at the volumes in the calculator below you're unlikely to outgrow it.

What pushes the price up
- Connecting to your other systems. Answering from your price list is simple. Writing the quote into your accounting package as well is a bigger build.
- Anything to do with money. Discounts and refunds need your approval built in, and that takes building and testing.
- Volume. Past 1,000 replies a month, WhatsApp's fees start to count, and the AI's fees grow with every chat.
- Testing. An assistant that talks to your customers should be tested by someone trying to trick it before they meet it. Some quotes leave this out, and then the problems turn up with real customers.
What we charge
Our Starter build is from R40,000 once, for one channel or one job, like answering your WhatsApps from your price list and booking people in. It includes a sea trial, where we try hard to break it before your customers see it, along with training for your team and your first month of Watch.
The running costs sit on accounts in your name, so you pay WhatsApp, the AI provider and the hosting directly and can see every cent. After the first month, Watch is optional, from R4,000 a month. A job that runs across two or three of your systems is R65,000 to R80,000, and several assistants working together start from R100,000. See Build and Watch for the details.
Questions to ask anyone who quotes you
- Whose accounts does it run on? If the WhatsApp number, the AI and the hosting are in their name, leaving them gets hard.
- What does it do when it doesn't know? It should ask you. Some make something up instead, like a price.
- Are WhatsApp's fees included? Since October 2026, replies past 1,000 a month cost money.
- Has it been tested against people trying to trick it? Ask to see the results in writing.
- Where does your customers' information go? Under POPIA, you're responsible for it.
Fair questions
Is the free WhatsApp Business app enough?
For one person answering by hand, often yes, and it costs nothing. An AI assistant needs Meta's WhatsApp Business Platform instead, which charges per message once a number goes past 1,000 free replies a month.
Do I pay anything in a month when nobody messages?
Just the hosting, about R80 a month, and support if you have it. WhatsApp and the AI only charge when messages go back and forth.
Can it answer in Afrikaans or isiZulu?
Usually, yes. It replies in the language the customer writes in, and we test the languages your customers use, on real messages, before it goes live.
Where these figures come from
- WhatsApp's fees: Meta's pricing documentation and Meta's rate calculator for South Africa, checked 20 October 2026, at about R16.45 to the US dollar.
- The AI's fees: measured on our own WhatsApp assistant in October 2026.
- Platform and agency prices: South African providers' published price pages, checked October 2026. Few agencies publish prices, so treat those ranges as rough.
