How to create a WhatsApp Business account: a practical guide

A customer messages you “are you open right now?” while you’re at the counter with ten other people. With a WhatsApp Business account that message instantly gets an automatic reply with your hours, and you reply for real when you can. It’s the first reason it’s worth spending ten minutes setting it up well, once. This guide walks you through it step by step, from registering the number to a complete business profile, all the way to the tools that save you time every day.

What WhatsApp Business is and how it differs from regular WhatsApp

WhatsApp Business is Meta’s free app designed for businesses, separate from the WhatsApp app you use to message friends. It’s installed separately and uses a different phone number: the idea is to keep the personal separate from the professional, so work conversations don’t mix with private ones. Beyond the normal chat, it adds a public business profile, automatic-reply tools, and simple conversation organization. It’s free, works on a single phone, and is perfect for those who handle messages by hand. The basic features are identical to the ones you already know: what changes is the work-oriented frame around them.

The concrete differences you’ll notice right away

• The business profile: address, hours, website, business category, visible to the customer before they even write
• The automatic greeting message for those who contact you for the first time
• The away message that goes out when you’re closed or off-hours
• Quick replies: saved phrases you call up with a slash, like “/hours” or “/shipping”
• Labels to organize customers, for example new, to follow up, order paid

What you need before you start

You need three things: a smartphone (Android or iPhone), an internet connection, and a phone number WhatsApp can verify by SMS or call. The number can be the business number you already use, but mind one point: a number can be associated with only one WhatsApp account at a time. If that number is already on regular WhatsApp, you’ll have to choose whether to migrate it or use a second number — another SIM or a landline — dedicated to the business. Keep your logo, address, and hours handy: you’ll need them to fill in the profile without interruptions. A few minutes of preparation save you from going back several times.

Step 1 — Download the app and register the number

Search for “WhatsApp Business” on the Play Store or App Store and install it: it’s free and takes little space. On opening, you accept the terms, enter the business phone number, and wait for the verification code that arrives by SMS. If the number was already on regular WhatsApp, the app offers to transfer the account: in a few taps you move chats and contacts without losing them, and from that point the number lives on the business app. If instead you use a new number, you start fresh with a clean contact list. Verification takes a minute and doesn’t need to be repeated.

Step 2 — Fill in the business profile

This is the part that makes the difference in the customer’s eyes, because it’s what they see before deciding whether to message you. Go to the business settings and fill in every field: business name (the one people search for you by, not an abbreviation), category, a short description of what you do, the address with the map, opening hours, email, and website or social profiles. Upload a sharp logo as the profile picture: an account with a photo and complete details conveys credibility, helps people find you, and reduces trivial questions, because many answers are already there. Take care over it: you fill it in once and it works for you for a long time.

Mistakes to avoid in the profile

• Leaving the description empty: it’s the space to say in one line what you sell and why to choose you
• Getting the hours wrong: the away message is triggered based on exactly these
• Using a low-resolution profile photo or a generic image instead of the logo
• Forgetting the address if you have a physical store: it’s what many customers look for first
• Not adding the website or socials: they’re the links that build credibility and go deeper

Step 3 — Set up the first automatic tools

Still in the business settings you’ll find the messaging tools, and this is where the app stops being a chat and becomes a little assistant. Set up a greeting message that goes out automatically on first contact: “Hi, thanks for messaging us. We reply within an hour during opening hours.” Configure the away message for when you’re closed, so no one is left without a reply in the middle of the night. Finally, create two or three quick replies for the questions you always get — hours, shipping costs, how to get there — and you’ll call them up with a few taps instead of rewriting them every time from scratch. It’s five minutes that save you hours in the weeks that follow.

When the free app is no longer enough

The WhatsApp Business app is great to get started, but it has three precise limits to know from the outset. First: it runs on a single phone, so only one person at a time really replies. Second: sending to multiple people goes through broadcast lists, limited to 256 contacts at a time and designed for manual use. Third: everything is manual, with no real automation beyond the basic messages. When you start getting too many messages for one person, want a team that replies together, or aim to send campaigns to thousands of contacts, you need another level. This is where platforms built on top of WhatsApp come in, adding power without making you change numbers.

With SendApp you connect the number you just registered and manage everything from the computer: multiple operators on the same number, campaigns, and automatic replies with AI. You can start by connecting your number via QR code with Cloud, or move to Meta’s official API with Official when volumes grow — on the same platform, with no markups on the cost of messages.

Good practices for the first few days

• Add the WhatsApp number everywhere: website, business cards, storefront, social profiles, email signature
• Create a QR code or a wa.me link so customers can message you with a single tap
• Reply quickly: on WhatsApp messages are read right away and speed is expected
• Use labels from day one: finding “who needs to pay” or “order shipped” will save you hours
• Don’t write first to people who haven’t contacted you without consent: it’s the golden rule to avoid getting blocked
• Update your hours before closures and holidays, so the automatic messages stay accurate
