WhatsApp Business is ideal for keeping work and private life separate. Where you mainly use WhatsApp Messenger for friends and family, WhatsApp Business is made for companies. This helps companies communicate better with their customers. And many business owners prefer to work on their computer. They can type faster and find customer details easily. They can also switch between channels simply. That is why there is a desktop version too. In this article you learn step by step how to use WhatsApp Business on your computer. This can be done through the browser, the app or the API.
WhatsApp Business on desktop via your browser
The quickest way is WhatsApp Web. This lets you easily link your phone to your computer and get straight to work with web whatsapp business.
Go to web.whatsapp.com
Open WhatsApp Business on your phone and go to Settings → Linked devices
Click on Link a device
Scan the QR code in your browser
You can find a full video about it here. From now on you can do customer service through your computer. It works in all browsers: Chrome, Safari and Firefox.
⚠️ Note: you can only use one telephone number per browser. If you have several numbers, you have to open a separate browser for each one. That makes it harder to manage several whatsapp business account profiles at the same time.

WhatsApp Business Desktop app for Windows & Mac
Besides the browser option there is also a WhatsApp Desktop app. Big advantage: you do not have to log in again and again. You miss no conversations if you accidentally close a tab.
This is how you install the app:
Download the WhatsApp Desktop app for Windows or Mac from the official website or the Microsoft Store or the WhatsApp website.
Open the app on your computer
In WhatsApp Business on your phone, go to Settings → Linked devices
Click on Link a device
Scan the QR code in the desktop app
From now on you also receive notifications on your computer when new messages arrive. This makes the whatsapp web business experience simpler and more stable.
WhatsApp Business API: for multiple users and numbers
Do you use whatsapp for business with several staff members or telephone numbers? Then you soon run into limitations in the browser and the app. The solution is the WhatsApp Business API.
With the API you can connect WhatsApp to your:
CRM system
Customer service software
Central dashboard with all your customer channels
That way several users can respond at the same time and you also manage other channels (Facebook Messenger and email, for instance) from a single overview.

Frequently asked questions about WhatsApp Business Desktop
Can I use WhatsApp Business Desktop with several numbers?
Not directly. You need a separate browser for each number, or the API.
Is there a separate app for WhatsApp Business Desktop?
No, there is one desktop app that you link to both WhatsApp Messenger and WhatsApp Business.
What is the advantage of the API?
You can connect several users, build CRM integrations and combine WhatsApp with other channels.
Can I manage group chats with WhatsApp Business Desktop too?
Yes, you can. With WhatsApp Business Desktop you can start and manage group conversations just as in the mobile app. You can add customers or colleagues to a group, send messages and share files. Do bear in mind that group chats become less manageable as the number of participants grows. For companies holding many conversations at once, the WhatsApp Business API is handier, because it lets you connect several users and manage conversations centrally.
