WhatsApp Business Web & Desktop: The Complete Guide

Yes. The WhatsApp Business app can be used on a computer in two ways: via WhatsApp Web (in the browser at web.whatsapp.com) and via the installed Desktop app (Windows/macOS). Both work as "linked devices": you pair them once with your Business account, then you see the same chats on the big screen.

The phone number stays tied to your primary device — web and desktop are mirrors, not a separate account.

In three steps:

1. On the phone, open the WhatsApp Business app → Settings → "Linked devices".
2. On the PC open web.whatsapp.com or launch the Desktop app — a QR code appears.
3. Scan the QR code with the phone → your chats appear on the computer.

In practice it takes under two minutes. [[VERIFY: confirm the current linking flow and device limit with Meta]]

Functionally they're almost identical — both mirror the same inbox. WhatsApp Web runs in the browser (nothing to install, handy for quick checks). The Desktop app is installed, gives more reliable notifications and feels like its own program. For working at the PC all day, the Desktop app is usually nicer.

Web and desktop are convenient, but it stays a one-account tool:

• Everyone sees the same inbox — no roles, no chat assignment.
• No real multi-agent work without people overlapping.
• No marketing automation (newsletters, flows) and no store integration.

Once several people work it, or you want WhatsApp as a revenue channel, that's the point for the API.

If you need multiple agents with roles, a shared team inbox, automation (cart recovery, shipping updates) or newsletters, the path is the WhatsApp Business API — at Keaz incl. a team inbox and flows, without the app's device limits. More in our articles on WhatsApp Business with multiple users and the difference between WhatsApp and WhatsApp Business.

Yes. WhatsApp Web and the Desktop app are free — they're part of the free Business app. Costs only start with the Business API (provider fee + conversation-based Meta fees), which you need for team operation and marketing.

Does the phone need to be online for WhatsApp Business Web to work?

Via linked devices, web/desktop works for a while even when the phone is offline — but you should keep the primary device online long-term. [[VERIFY: current behavior with Meta]]

Can several staff work over WhatsApp Web at the same time?

Only in the same shared inbox without roles — for real team work with assignment you need the Business API and a team inbox.

Is there a WhatsApp Business desktop app for Windows and Mac?

Yes, for both. Alternatively it runs in the browser via WhatsApp Web.
