Walk through any Lagos market conversation about a purchase and it ends the same way. Send me a message on WhatsApp. For a huge number of Nigerian businesses this is not a support channel, it is the shop, the checkout and the customer service desk at once.
Which makes it strange how many are running it from a personal account with a profile photo of somebody’s children, no business name, no catalogue, and no reply until whenever the owner next picks up the phone.
WhatsApp Business is free, takes about an hour to set up properly, and is almost certainly the highest return hour available to a small Nigerian business that already sells this way.
Business or personal, and why it matters
WhatsApp Business is a separate free app. It looks nearly identical to the one you already use, and it adds the things a business needs: a profile with your address and hours, a product catalogue, automatic replies, labels for organising conversations, and short replies you can fire off without retyping.
You can run it on the same phone as your personal WhatsApp if the two use different numbers. Most people should. Mixing customer orders into the same thread as family messages is how orders get missed, and it means you can never hand the account to somebody else without handing over your private life with it.
If you are already trading on a personal account, the app will offer to migrate your existing chats when you switch. Do that rather than starting empty, so your conversation history and your existing customers come with you.
The profile, which is the part most people leave blank
Your business profile is what somebody sees before they decide whether you are real. Fill in all of it.
Business name. Your actual trading name, spelled the way it is spelled everywhere else. Not your name plus a list of what you sell.
Category. Pick the closest one. It is coarse, and it still helps.
Description. One or two sentences saying what you sell and where you are. This is the field people read when deciding whether they have the right number.
Address. If customers can visit you, put it in. If you deliver only, say the areas you cover.
Hours. Real ones. A business showing as open at eleven at night, that then does not reply, has told the customer something about itself.
Website and email. Both, if you have them. This is one of the links that helps a search engine connect your WhatsApp presence to the rest of your business.
Profile photo. Your logo or your shopfront. Not a personal photo, and not a stock image of a handshake.
The catalogue, which is the actual selling tool
The catalogue turns WhatsApp from a chat app into a shop, and it is the feature most businesses never touch.
Each item takes a photograph, a name, a price, a description and optionally a link and a product code. Once it exists, a customer asking what do you have can be sent the whole catalogue in one tap, or a single item as a card with the price attached.
A few things that make the difference between a catalogue that sells and one that sits there. Photograph items on a plain background in daylight, because a bright clear photo of an ordinary product beats a dark photo of a beautiful one. Put the real price in the price field rather than writing "DM for price", because hiding the price adds a step and loses the buyers who were only browsing. Write descriptions that answer the question the customer would otherwise have to ask, which is usually size, colour options, material, or how long delivery takes.
And keep it current. A catalogue full of things you no longer stock generates conversations that end in disappointment.
Automatic messages, used carefully
Two settings worth turning on and one worth thinking about.
The away message fires when somebody writes outside your business hours. Use it to say when you will reply, not to apologise. "Thanks for your message. We reply between 9am and 6pm, Monday to Saturday" sets an expectation the customer can live with.
The greeting message fires the first time a new person writes. Keep it short and make it do work: say what you sell, and ask the one question that speeds everything up, which is usually what they are looking for.
Quick replies are saved answers you trigger with a keyword. Set them up for the five questions you answer every single day. Delivery areas and cost. Payment details. Opening hours. How long a custom order takes. Your location with a pin. That is twenty minutes of setup that saves an hour a week forever.
What not to do is automate the actual conversation. Nigerian buyers can tell, and the whole advantage of WhatsApp over a website is that there is a person at the other end.
Labels, so nothing gets lost
Labels are WhatsApp’s version of a sales pipeline and they cost nothing. New enquiry, awaiting payment, paid, to deliver, delivered, follow up. Apply one to every conversation as it moves.
The reason to bother is that the most expensive thing that happens on WhatsApp is not a lost sale, it is a conversation that went quiet at the payment stage and was never chased because it scrolled off the screen.
Getting found, which is the part nobody sets up
A WhatsApp account that only your existing customers know about is a service channel. To make it a growth channel it has to be findable.
Create your click to chat link. It is your number in international format with no plus sign and no spaces, on the end of wa.me. For a Nigerian number starting 0803, drop the zero and use 234, so it becomes wa.me/234803... Test it from a phone that has never messaged you.
Put that link everywhere. Your website, your Instagram bio, your Facebook page, your Google Business Profile, your email signature, your invoices. Every place it appears is one fewer step between interest and a conversation.
Add it to your Google Business Profile if you have one, so somebody finding you on Maps can message you directly. If you have not claimed that yet, that is a separate job worth doing first.
Keep the number consistent. The same number on the website, the listings and the social bios. Different numbers in different places is the single most common reason a customer decides a business looks unreliable.
The mistakes that cost the most
Replying slowly. WhatsApp sets an expectation of minutes, not days, and a business that takes two days to answer has effectively told the customer to buy elsewhere.
Broadcasting to everyone. Sending unsolicited promotional blasts to your whole contact list gets accounts reported and eventually blocked, and it annoys the customers you already have.
Taking orders and payment entirely in chat with no record anywhere else. It works until there is a dispute, and then nobody can prove what was agreed.
And treating it as separate from everything else. WhatsApp is usually the last step of a journey that started on Google or Instagram. If the earlier steps do not exist, a perfect WhatsApp setup just serves the few people who already knew about you.
That last one is the whole argument for looking at the full picture rather than one channel, which is what our free deep digital audit does. It checks everything a customer meets on the way to you, from the outside, and tells you which part is actually broken.
