Kenyan businesses run on WhatsApp. That is not a marketing observation, it is just where the enquiries arrive. What is less well understood is that there are three different WhatsApp products, they cost different amounts, and most businesses are on the wrong one for their size.
The three products
WhatsApp Messenger is the personal app. One phone, one person, and no business features. A surprising number of Kenyan businesses still run on it, usually the founder's own number.
WhatsApp Business is the free app built for small businesses. It adds a catalogue, labels, quick replies and away messages. It is genuinely good, and for a business handling a handful of enquiries a day it is the correct answer. Anyone telling you otherwise at that volume is selling you something.
Its ceiling is real, though. It is still one phone and effectively one person. Automated replies are limited to canned text — there is no way to check stock, take a payment or look up an order. And broadcast lists are capped and get you reported if used enthusiastically.
The WhatsApp Business Platform, still widely called the API, is the third. It has no app of its own. It is a connection between WhatsApp and whatever systems you run, so that a reply can be generated rather than typed, several staff can work the same number, and messages can be sent programmatically through an approved channel.
What changes when you move to the API
Three things, and they are the only three worth moving for.
Replies can be computed, not just canned. An agent can check what is actually in stock, quote the current price, take an order, raise an M-Pesa prompt and confirm when the payment lands. That is a different category of thing from an away message.
More than one person can work the number. Enquiries can be assigned, a conversation has a history that survives someone leaving, and nobody has to hand over a physical phone.
Broadcasts stop being risky. Messages sent to people who have not messaged you first use pre-approved templates and go through the official path. On the free app, the same behaviour gets numbers reported and blocked, which is the single most expensive mistake a growing business makes on WhatsApp.
What it costs
There are two bills, and conflating them is where most quotes become misleading.
Meta's bill. WhatsApp charges per conversation, not per message, with rates that vary by conversation category and by country. Service conversations — the customer messaged you first — are cheaper than marketing conversations you initiate, and Meta has been shifting the pricing model periodically. This is billed to your own account, not to us, and we do not mark it up.
Because the rates change, we will not print a number here that will be wrong in six months. What we do instead, before you commit to anything, is take your actual monthly enquiry volume and produce an estimate against Meta's current published rates. If that number is uncomfortable at your volume, the honest answer is to stay on the free Business app for now, and we will say so.
The build. Setting up the API access, building the agent, connecting it to your stock or booking system, getting templates approved. That is our fee, and ours starts at KSh 80,000.
There may also be a third: some businesses reach the API through a Business Solution Provider who adds a platform fee. We set clients up directly on their own account where that is the better arrangement, and tell you when it is not.
Business verification
Meta requires your business to be verified before you get full sending access. In practice this means having your registration documents in order and a business presence that is checkable.
For a properly registered Kenyan company with a website and a matching phone number, this usually clears within a few days. It occasionally takes longer, and nobody — not us, not a solution provider — can compress Meta's review. We start it in week one and build the agent while it runs, so it rarely delays a launch.
The one thing that reliably causes trouble is inconsistency: a business name on the WhatsApp application that does not match the certificate, or a website that does not name the same company. Fix that before applying rather than after being rejected.
When you do not need it
Be suspicious of anyone who tells you every business needs the API.
If you handle fewer than roughly thirty enquiries a day, one person can genuinely keep up, and the free Business app with a good catalogue and well-written quick replies will serve you. The API's advantages — automation, multiple agents, safe broadcasting — all only pay off above a volume that makes the per-conversation cost worth it.
The signals that you have crossed the line are specific. Enquiries going unanswered overnight and customers saying so. One person unable to take leave without the business slowing down. A broadcast list you are nervous about using. Orders taken in chat that then have to be retyped into another system. Two of those and it is time; none of them and it is not.
What to ask a developer
If you are getting quotes, four questions separate a serious answer from a vague one.
Will the account be in our name, so we own the number and the history? What is Meta's estimated monthly cost at our specific volume? What happens when the agent does not know an answer — where does the conversation go? And what do we do if we want to stop using you?
A supplier who answers all four plainly is one worth talking to. Those are also, for what it is worth, the four things we put in writing before starting.
