WhatsApp Business App for a Small Business: Setup and Cost

A customer asks, "Can I WhatsApp you?" and you say yes, then answer from your personal number at ten at night between your own family's messages. It works until a message gets buried, a customer sees your private photo, or you start wondering whether "free" really means free. The WhatsApp Business app is built for exactly this situation. It is a separate app, free to download, that gives you a business profile, a catalog, quick replies and automatic greeting and away messages. It is also easy to confuse with two other things that share the name, personal WhatsApp and the paid WhatsApp Business Platform, and mixing them up is where owners lose time and money. Getting the right one first saves you a restart later. You can set up the app yourself in about an hour, and most of that is typing your own business details.

Which WhatsApp do I actually need for my business?

There are three, and the names are close enough that it is easy to download the wrong one. WhatsApp's own About WhatsApp Business page separates them, and the differences matter for cost and setup.

The app is the one to start with. It handles a professional profile, saved answers and automatic replies without any developer. The Platform uses approved message templates and Meta's pricing, which varies by recipient market, message category and the current rate card. So, if you ever look at it, check Meta's current pricing page for your country, because a single dollar figure would be wrong for most readers. The app does not need the Platform to work, and you do not need the Platform to look professional.

How do I set up the app without mixing it with my personal account?

Start with the number, because it is the hard step to undo. A phone number can run either personal WhatsApp or the Business app, not both at once. If you use your personal number, your existing account can be moved to the Business app, and you should look at your backup options first so your chats come with it. A dedicated business number keeps customer chats away from your personal ones, which is the cleaner choice if you can get one.

Then follow the steps in WhatsApp's Help Center, current as of October 2026. The exact button names may shift, so look for the closest match in your app.

1. Download the app: Get the WhatsApp Business app from Google Play or the Apple App Store, following WhatsApp's download instructions.
2. Verify your number: Accept the terms, verify the number and restore a backup if one is available.
3. Build the profile: Add your business name, category, description, address, hours, email, website and a profile image. WhatsApp's page on editing your business profile covers each field.
4. Add a small catalog: In Tools, create a catalog with item names, images, descriptions, prices where available, links and item codes. Items may need WhatsApp approval before customers see them, and price display varies by country. WhatsApp explains how in its catalog guide.
5. Turn on a greeting and an away message: The greeting message welcomes first-time or inactive contacts. The away message goes out on a schedule you choose, to recipients you choose.

Start the catalog with three accurate services or products. A short, current list serves a customer better than fifty items nobody maintains.

What can I stop typing by hand every day?

Quick replies are saved messages for questions you answer again and again. You type a short shortcut, and the full reply appears. Good first ones are your hours, how to get a quote and your location. They are starting points, not a chatbot, so change each reply to fit the person you are talking to rather than sending the same block of text to everyone.

Labels help you sort chats so nothing sits unanswered. Simple ones work well, such as New lead, Waiting for quote, Paid and Follow-up. A label takes a second to add and saves you scrolling back through a week of messages.

Test the whole setup before a customer does. Send a message to your business number from another phone, and check that your profile, greeting and away message show up the way you meant. An away message set to the wrong schedule or recipients will not reach people, and you will only learn that from a customer who was left waiting.

How do I know my profile is ready in ten minutes?

Use this check on a single phone with a second phone nearby.

1. Decide whether the number is dedicated to the business or moved from a personal account.
2. Install the Business app, verify the number and restore a backup if one is available.
3. Fill in your business name, category, description, hours, address, email, website and image.
4. Create three quick replies, such as `/hours`, `/quote` and `/location`.
5. Turn on a greeting message for new or inactive conversations.
6. Set an away message for the hours you are closed.
7. Message the business from another phone and read what a customer sees.

Add the catalog after this works. Do not start with mass messaging, automation or the Platform unless your basic way of answering customers is already clear.

Fixes are usually small jobs. A wrong or missing profile detail takes under an hour. A greeting or away message that does not send is a settings check. A rejected or outdated catalog item means replacing it or adding the missing fields. Moving between numbers, or sorting out what happens to an existing personal account, deserves a slower look at your backup first.

How do I message customers without losing the account?

Your replies are free-form, but anything you start yourself needs permission. WhatsApp's Business Messaging Policy requires a customer's mobile number and explicit permission before you send subsequent messages. Your opt-in should clearly name your business and say the person agrees to receive WhatsApp messages. Honor any request to stop, block or opt out. Having a customer's number saved in your phone is not permission.

The same policy bars spam and misleading or surprising messages. WhatsApp may limit or remove access after policy violations, heavy negative feedback or unauthorized large-scale messaging. In practice, that means a short, useful reply to someone who just wrote to you is safe ground, and a blast to everyone in your contacts is not.

On the Platform, one more rule applies. A business can start a conversation only with an approved message template. It can reply without one during the 24-hour customer service window that opens after the customer's latest message, and outside that window a template is required again. Automated replies are allowed during the window, but the business must give a clear way to reach a person, such as a phone number, email or support form.

Other laws can apply as well, and WhatsApp's policy does not replace them. In the United States, the FCC explains the Telephone Consumer Protection Act, and the FTC's CAN-SPAM guide covers commercial email. Rules differ by country and by the kind of message, so check with a lawyer if you plan to send marketing messages.

When is the free app no longer enough?

The app fits one or two people answering customer-started chats by hand, with a simple catalog and saved replies. Move up when the work outgrows one phone. That means several staff need one shared inbox, you want WhatsApp tied to your website or customer records, you need appointment or order automation, or you want proactive notifications at a larger volume. Meta Business Suite can bring Facebook Messenger, Instagram and WhatsApp messages into one inbox when the business accounts are connected and eligible, and Meta's Inbox help page explains the setup. WhatsApp's own policies still apply to the WhatsApp side.

At that point the Platform's costs and the work to connect it become part of the decision, not an afterthought. If you want to understand what an automated assistant would and would not do for a small business, our post on whether a website chatbot is worth it covers the same trade-off.

You can set up the app yourself and run it for as long as it fits. Paying someone helps when the channel becomes part of how the business runs, such as choosing the number, protecting a migration, connecting systems, documenting permission and deciding when Platform costs are worth paying. It does not help to pay for the download, which is free.

Frequently Asked Questions About whatsapp business app

Is the WhatsApp Business app free?

Do I need the Platform or an API to make a catalog?

No. The WhatsApp Business app supports a business profile and a catalog.

What are quick replies?

Saved messages for questions you answer often. They are not a chatbot, so adjust them to each customer.

Do customers have to opt in?

Yes. WhatsApp requires a phone number and explicit permission before you send subsequent messages.

What is the 24-hour customer service window?

On the Platform, a business can reply without a template during 24 hours after the customer's latest message. Outside that window, an approved template is required.

Moving Forward

WhatsApp, the WhatsApp Business app and the WhatsApp Business Platform are three different things. The app is free to download and covers a profile, a catalog, labels, quick replies, a greeting and an away message. The Platform is for larger teams and automation. Choose the number first, test your setup from another phone, and ask permission before you send anything a customer did not ask for.

Once the app is set up, customers can find your hours, see what you offer and get a quick answer, even when you are with someone else. Check your profile whenever hours or services change so it stays accurate.

If you want help beyond the app, Web Leveling can plan how WhatsApp fits with your website and your other channels. Our social media marketing work covers the setup and the habits that keep it working, and our chatbot work applies once you need shared inboxes or automated replies. If the free app is enough for you, we will say so. We work with small and medium businesses across the country and overseas.
