WhatsApp Business Web & Desktop: Use It on a PC

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. How many devices you may link at once, and how long they keep working while the phone is offline, are rules Meta sets and changes — so check them at the source rather than trusting any blog post, including this one: About linked devices on the WhatsApp Business app (WhatsApp Help Center).

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.

The difference is easiest to see side by side. A proper team inbox gives every conversation an owner, a status and a filter — see how the Keaz inbox is laid out and what a single conversation view holds. We covered the wider question in how small teams share one WhatsApp number.

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. That is what Keaz flows, newsletters and the team inbox are built on, without the app’s device limits.

Two neighbouring questions come up constantly, and we answered both separately: running WhatsApp Business with multiple users and the difference between WhatsApp and WhatsApp Business.

Yes. WhatsApp Web and the Desktop app are free — they are part of the free Business app. Costs only start with the Business API, where you pay your provider plus Meta’s own message fees.

Those fees are charged per delivered message, by recipient market and template category — Meta replaced the older conversation-based model on 1 July 2025. Current rates are published in Meta’s WhatsApp Business Platform pricing documentation (retrieved 24 August 2026); we deliberately do not restate the numbers here, because they change quarterly.

Most of the trouble with WhatsApp Business on a computer comes from expecting it to be something it is not. Four patterns come up again and again:

• Treating web and desktop as a team inbox. Every linked device shows the same chats, with no owner, no status and no assignment. Two people on the same screen will answer the same customer twice.
• Leaving the primary phone out of the plan. Web and desktop mirror one handset. If it is lost, replaced or wiped, the mirrors go with it — decide who holds that phone before the shop depends on it.
• Expecting marketing features on a bigger screen. Newsletters, automated flows and Shopify triggers are not in the free app at all. They arrive with the API — see what the platform adds.
• Planning around device limits read once in a blog post. How many devices you may link, and how long they run while the phone is offline, are Meta’s rules and Meta changes them. Check the WhatsApp Help Center on the day you need the figure.

All four are cheap to avoid up front and expensive to unpick once a team has built habits around the wrong tool.
