Meta has put an AI assistant inside the WhatsApp Business app, and since September it has been pushing it at Nigerian small businesses by name. That turns it into a social media management decision rather than a tech story. The chat where most of your orders actually close is about to have a second voice in it, and that voice has never seen your stockroom.
Meta announced the global rollout of Meta Business Agent on 3 June 2026 at its Conversations conference in London, after roughly two years of testing in markets including India and Mexico (TechCrunch). In September 2026 it ran a three-week campaign here called "Power Your Hustle with WhatsApp Business", featuring owners in Lagos, Ibadan and Abuja who all use the agent (The Guardian). If you sell on WhatsApp, someone is going to show you that toggle.
What Meta Business Agent actually does
It replies to your customers when you do not. Meta says the agent answers questions, recommends products, books appointments, qualifies leads and passes the conversation to a human when it cannot finish the job (TechCrunch). You turn it on from inside the WhatsApp Business app, with no developer and no setup fee.
It also works in Instagram DMs and Messenger, which is the part that matters if you are the one person answering all three.
What it knows is only what you wrote down
The agent reads your business profile and your catalog. That is the whole of its world.
It does not know that the grey duvet sold out on Friday, or that the price on the catalog is three weeks old because you were in the market. It will answer anyway, in a confident sentence, because that is what these models do when they are short of facts. One customer getting a wrong delivery fee is a refund argument, not a saved minute.
So the useful question is not whether the AI writes well. It writes fine. The question is whether what you have written down is current enough for a stranger to quote back at you.
What it would get wrong in a shop in Awka
Take a bedding shop off Zik Avenue in Awka. Call the owner Ngozi. She sells duvets and bedsheets, most orders start as a comment under a photo, and all of them finish in WhatsApp. Three questions make up the bulk of her chats: is the grey one available in six by seven, how much is delivery to Onitsha, and can you do ₦16,000 instead of ₦18,000.
An assistant reading her catalog handles the first question only if the catalog is honest about sizes and stock, which almost no small catalog is. It handles the second only if her delivery prices are written somewhere it can see. The third is the one to worry about. Nigerian selling is a negotiation, and a model that wants to be helpful is a soft negotiator. An agent that cheerfully agrees to ₦16,000 on an item she clears ₦2,500 on has not answered a question, it has cost her the sale she thought she made.
Ngozi's fix was boring and it worked. She spent one evening writing her twenty most-asked questions on one page with the exact answer she would give, including the ones she usually answers by voice note. Anything that depended on stock or price went on a second list, and those became the ones a human replies to. Her catalog got a half-hour clean-up in the same sitting. The assistant now handles sizes, fabric, wash instructions and opening hours, and she still sends every price herself.
Write the answer sheet before you touch the toggle
This is worth doing even if you never switch any AI on, because the sheet is the asset.
Scroll back through two weeks of customer chats and copy out every question a customer asked, not the ones you imagine they ask. The real list is usually shorter than you expect, and you have probably been retyping the same eight answers for months. Write the answer you would actually send under each. Then split the page in two: answers that are true no matter what happened in the shop today, and answers that depend on stock, price or delivery. Only the first half is safe to hand over.
Then test it like a customer. Take a second phone, message your own business, and ask the three questions you would least like to get wrong. If the reply is wrong once in ten tries, that is one customer a week in a shop doing seventy chats a week.
What it costs, and what Meta has not published
In the WhatsApp Business app, the agent starts free with a monthly allowance whose size Meta has not published. Extra capacity comes through Meta One plans from around $14.99 a month (Robylon). On the WhatsApp Business Platform, which is the API route most larger sellers use through a provider, token billing for agent conversations began on 1 August 2026 at $2.00 per million tokens, which third-party estimates put at roughly four to five US cents a conversation (Wati).
Treat those figures as a starting point rather than a bill. Sources disagree on the dates, the free allowance is not documented, and it all sits on top of the per-message charges Meta began applying to Platform replies on 1 October 2026, which we worked through in an earlier post. For a shop on the free app answering a few dozen chats a day, the cash cost is probably nothing. On the API with real volume, price it before you scale it.
When the answer is no
If your prices move weekly, if most of your margin comes from what you negotiate in the chat, or if you sell something where a wrong answer is a health or safety problem, leave it off. Food with allergens, medication, anything fitted, anything with a warranty. The saved minutes are not worth the one message you have to apologise for.
Leave it off too if you have not written the answer sheet. An AI pointed at an empty catalog is a faster way to be wrong.
Where software helps and where it does not
Replying is the smaller half of the problem for most Nigerian sellers. The bigger half is that there is nothing to reply to, because nobody posted for nine days. An assistant in the inbox does not fix an empty feed.
That is the gap Threadovo sits in. It is social media management software that also makes the content: it plans the week, writes the captions, makes the images and clips, and posts them on schedule. Its Engage side drafts replies to comments and DMs and flags complaints, but a person still presses send, which is a different choice from handing the conversation over, and a deliberate one. Pricing is in naira from ₦39,000 a month, with a 14-day trial and no card, on the pricing page. It will not negotiate your duvet price either, and it should not.
The lasting lesson from 2026 has nothing to do with which assistant you pick. Every one of these tools, Meta's included, is only as good as the written answers behind it. Write those down and the tool choice gets easy. Skip them and no tool saves you.
Questions people ask
Is Meta Business Agent free?
In the WhatsApp Business app it starts free with a monthly allowance that Meta has not published, and more capacity comes through paid Meta One plans from about $14.99 a month. On the API route, conversations handled by the agent have been billed by token usage since 1 August 2026.
Will the AI reply to customers without my permission?
No. You switch it on yourself in the WhatsApp Business app, and you can switch it off the same way. It is also limited to eligible businesses in selected countries, so you may be on a waitlist rather than facing a choice.
Can it handle Nigerian Pidgin or mixed English?
Meta has not published language support for it in Nigeria, so test it rather than trust it. Send yourself a few messages in the way your customers actually write, including Pidgin and the short forms people use for sizes, and read what comes back before you let it loose.
Does using an AI to reply hurt my reach?
No. How you reply in WhatsApp has nothing to do with how Instagram or Facebook rank your posts. A slow or wrong reply can still lose you the customer, but that is a sales problem rather than an algorithm one.
What should I do first if I only have one evening?
Write the twenty questions your customers actually asked in the last two weeks, with the answer you would send, and fix your catalog prices and sizes. That one page is what makes any assistant useful, and it is worth having even if you decide against one.
