How to Set Up WhatsApp Business: The Complete Guide (2026)

If customers are messaging you on WhatsApp, you should be on WhatsApp Business — the free, purpose-built version of WhatsApp with a business profile, catalog, and automated replies. Setting it up takes about ten minutes. This guide walks through how to set up WhatsApp Business from scratch, gets your profile looking professional, and shows where the free app stops and automation begins.

Before you start: choose your number

The one decision to make first is which phone number to use:

• A separate business number (recommended) — keeps work and personal life apart, can be shared by your team via linked devices, and looks professional. Get a second SIM or eSIM.
• Your personal number — works, but you'll have to migrate it (you can't run the same number on both the personal and Business apps at once), and it blurs the line between business and personal chats.

A number that isn't currently on a personal WhatsApp account is the cleanest start. Once you've decided, you're ready.

Step 1: Download and install

1. Get the WhatsApp Business app from the App Store (iPhone) or Google Play (Android). It's free and separate from the regular WhatsApp app.
2. Open it, agree to the terms, and enter your business phone number.
3. Verify the number with the SMS or call code WhatsApp sends.
4. If you're migrating a number that had personal WhatsApp, the app offers to move your chat history.

That's the account created. Now make it look like a real business.

Step 2: Build a professional business profile

Your profile is your storefront — customers judge you on it in seconds. Tap Settings → Business tools → Business profile and fill in everything:

• Business name — your real, recognisable name (you can't change it often, so get it right).
• Logo as the profile photo — clear and on-brand.
• Category — pick the closest fit.
• Description — a short, warm line on what you do.
• Address — so customers can find you (and get a map link).
• Hours — accurate opening times; these also power the away-message schedule.
• Website, email — and any booking link.

A complete profile builds instant trust — even before anyone messages you. Don't skip it.

Step 3: Add your catalog

If you sell products or services, add a catalog so customers can browse right inside WhatsApp. Go to Business tools → Catalog → Add item and add photos, prices, and descriptions. You can then send individual items in a chat, turning conversations into sales. We cover this in depth in our WhatsApp Business catalog guide.

Step 4: Set up auto-replies

Customers message at all hours — auto-replies make sure nobody's ignored:

• Greeting message — a warm welcome sent automatically to new customers.
• Away message — sent when you're closed or busy, on a schedule.

Set both under Business tools. For ready-to-use wording, see our auto-reply setup guide, greeting examples, and away message examples. These are your safety net so no message goes unanswered.

Step 5: Add quick replies and labels

Two small features that save real time:

• Quick replies — save your most-typed messages (address, price list, "thanks, we'll confirm shortly") and insert them with a shortcut.
• Labels — colour-code chats (New customer, Pending payment, Order complete) to stay organised.

Set these up under Business tools once you're taking regular messages.

Step 6: Get customers messaging you

Now make it easy for people to start a chat:

• Click-to-chat link — a wa.me link you can put anywhere (see how to create one).
• Website button — a floating WhatsApp button on your site (how to add one).
• QR code — for print, packaging, and your storefront (WhatsApp QR codes).

The easier you make it to reach you, the more conversations — and customers — you get.

Where the free app stops

The WhatsApp Business app is excellent for a solo owner or tiny team. But you'll hit its limits as you grow:

• Auto-replies are fixed text — they can't answer a question, quote a price, or take a booking.
• It runs from one phone (plus up to four linked devices), with no real team roles.
• No automation, chatbots, or integrations.
• No AI to handle the flood of repetitive questions.

When those limits start costing you time or customers, it's time to level up.

When to move to the API or an AI receptionist

Two upgrade paths, depending on your need:

• The WhatsApp Business API — for automation, chatbots, multi-agent teams, and scale. It's the engine behind everything advanced. See what the WhatsApp Business API is and how it compares to the app.
• An AI receptionist — the fastest way to actually answer customers 24/7. It plugs into your WhatsApp number and replies with real information from your business — prices, hours, bookings — in any language, even to voice notes. See how an AI WhatsApp assistant works.

Most businesses set up the free app first, then add an AI receptionist the moment missed and after-hours messages start costing them bookings.

The takeaway

Setting up WhatsApp Business is quick: pick a number, install the app, complete your profile, add a catalog and auto-replies, and make it easy for customers to reach you. That alone puts you ahead of businesses still using a personal number. When you're ready to stop just acknowledging customers and start answering them around the clock, add an AI receptionist.
