If you run your business on WhatsApp Business, you already have a link even if you never made one: the app ships with it. It sits in a menu few people open, and it comes with a couple of limits worth knowing before you print it on anything.
The app and the platform are not the same thing
Two different products share the name “WhatsApp Business”, and mixing them up sends you looking in the wrong place:
- The WhatsApp Business app: free, downloaded like any other app, built for businesses answering from a phone. That is the one this guide is about.
- The business platform (the API integration): built for large volumes, contracted through providers and billed per conversation. There, links are managed from the provider’s side.
For 95% of small businesses, the app is plenty.
Your Business number already works with wa.me
First thing worth knowing: there is no special format for Business accounts. The link is the same as for any number:
https://wa.me/5215512345678Country code and number, no +, no spaces, no dashes. If yours doesn’t open, it is nearly always that: the format. It is broken down country by country in the guide to creating a WhatsApp link.
The short link the app gives you
The Business app generates its own and hands it to you ready to share. Depending on your version, the path is:
- Open WhatsApp Business and go to settings.
- Find Business tools.
- Open Short link.
There you get your link, the option to write a pre-filled message that appears typed when someone opens it, a downloadable QR code, and buttons to share it straight to social networks.
It is free, it is official, and to start with it is fine. If all you need is a link in your Instagram profile, you are done.
What that link can’t do
The limits show up as soon as the business grows a little:
- There is only one. The same link for the shop window, the bio, your ads and your cards. When someone writes, you have no idea which one they came through.
- It can’t be redirected. The number lives inside it. Change lines and everything published points at a number nobody answers — printed material included.
- It doesn’t count clicks. You know how many conversations you have, not how many people opened it and never wrote.
- You can’t choose the address. No alias: it is your number, and a number is neither easy to dictate nor to remember.
- One message for everything. The same opening text no matter where the person came from.
That is where your own link comes in: you can create one free with a readable alias, an editable destination and a different link per channel.
Your catalogue link
If you have loaded products into the app’s catalogue, it has a link of its own and shares just like the chat one. You’ll find it inside the catalogue, under the share option.
It earns its keep when the question you get over and over is “what do you have?” or “how much is it?”: instead of retyping the list, you send the catalogue and the conversation starts at a specific product.
The opening message does half the work
A link that opens an empty chat leaves the customer wondering what to write, and a share of them leave without writing anything. With a pre-filled message the conversation starts itself, and it reaches you with context.
The interesting part is changing it depending on where the person came from: “Hi, I saw the Facebook ad”, “Hi, I’d like to book a table”, “Hi, I scanned the QR at the counter”. Each message tells you the source without you having to ask. There are ready-made templates in the pre-filled message guide.
Don’t confuse it with the app’s greeting message, which is a different thing: that one you send automatically when someone writes to you for the first time. The two work well together — one opens the conversation, the other replies instantly even when you’re busy.
From link to QR code
The same link, printed, covers everything that happens offline: counter, table, shop window, packaging, vehicle. You can generate the QR free, and the QR code guide has the size it needs for the reading distance and how to stop it from failing to scan.
When more than one person answers
The Business app is designed around one phone. As soon as two or three people are answering, the trouble starts: somebody has to carry the company mobile, messages get answered twice or not at all.
If that sounds familiar, what is missing isn’t another link but a split: a team link sends each conversation to a different agent, and analytics tells you how many come in through each channel.
Common mistakes
- Testing the link on the same phone that holds the account. It always looks fine there. Test from another one.
- Publishing the number without the country code because “everyone here is local”. It breaks the moment somebody writes from abroad.
- Printing the app’s link on something expensive and changing numbers six months later.
- Leaving the opening message as “Hi”: that throws away the only free clue about where people came from.
- Trying to run the personal and Business accounts on one number: only one of them can use it.
Frequently asked questions
Do I lose my chats moving from regular WhatsApp to Business?
The app offers to migrate your history when you switch, keeping the same number. Take a backup first, just in case.
Can I have two numbers on one phone?
Yes: one in regular WhatsApp and another in WhatsApp Business, as long as they are different numbers. It is the usual way to keep personal and business apart.
Do I need a landline or a company number?
No, an ordinary mobile works. What matters is that you can receive the verification code.
Does the customer need WhatsApp Business too?
No. They write from their usual WhatsApp; the difference is only on your side.
Summary
- Your Business number works with
wa.melike any other. - The app has a short link with a message and a QR under Business tools.
- That link is a single one, can’t be redirected and counts nothing.
- One link per channel, each with its own message, tells you where customers come from.
- If more than one person answers, the next step is splitting, not adding links.
