The customer sends a message asking about the price, waits a few minutes, gets no reply, and calls the competitor instead. For a large share of small businesses in Brazil, WhatsApp is the store counter — and the free business app already includes five tools that fix this delay without hiring anyone. The whole setup takes about twenty minutes.
First things first: WhatsApp Business, not the personal app
The tools in this article only exist in WhatsApp Business, Meta's own free app for companies. It can run on the same phone as personal WhatsApp, each with its own number.
Selling through a personal number is the most common mistake: it mixes customers with family, has no business profile with address and hours, and misses out on every tool below. If the number customers already know is the personal one, it can be transferred to Business while keeping the conversations.
All the settings are under Business Tools, in the app's menu. The exact menu name varies slightly between versions and between Android and iPhone, but the group of tools is the same.
1. Greeting message: no one goes unanswered on first contact
This is the message sent automatically to anyone who writes to your business for the first time, or after 14 days without talking. It doesn't replace customer service; it holds the customer's attention until you get there.
A good message has three parts: greeting, timeframe, and the next step.
Example: "Hi! Thanks for reaching out to Padaria do Bairro. I'll reply within a few minutes. In the meantime, today's menu is in our catalog."
2. Away message: closing time still gets a response
This is the automatic reply for anyone who writes when you're not available. You can choose when it applies: always, during a custom schedule, or outside the business hours set in your company profile.
What it needs to say is when the customer will be attended to. "We're closed" without a return time sends the person looking elsewhere.
Example: "We're closed right now. We're back tomorrow at 8am and your message will be the first one answered."
3. Quick replies: the same question answered in two taps
Delivery price, address, payment methods, hours: every business answers the same questions dozens of times a week. Quick replies store these texts with a shortcut. Mid-conversation, just type a slash, "/", and pick the reply from the list.
To get started, take the five questions you get most often and write the best answer for each one, carefully, just once. From then on they go out complete and typo-free every time.
4. Catalog: the customer chooses without having to ask
The catalog is a storefront inside WhatsApp, with photo, price, description, and link for each product or service. Customers open it from the business profile, and you can send a specific item in the conversation instead of typing out the full description.
Three details make a difference:
- A clear photo, with the product in use whenever possible — a sliced cake sells better than the closed box.
- Visible price. An item with no price turns into a question, and a question turns into a wait.
- An up-to-date catalog. Products that are out of stock need to come down, or the customer's first response is a disappointment.
5. Labels: no sale gets lost in the chat list
With dozens of conversations a day, the order that was left half-finished disappears down the list. Labels mark each conversation by status, with a name and color, and the app allows up to 20 of them.
A simple set already covers most cases: new customer, quote sent, payment pending, order ready, and returning customer. At the end of the day, filtering by "payment pending" shows exactly who needs a reminder.
Check before you finish
- Does the greeting message say when you'll reply and what the next step is?
- Does the away message say what time you'll be back?
- Have your five most frequent questions already become quick replies?
- Does every catalog item have a photo and a price?
- Do the labels match the real stages of your sales process?
Businesses serving customers in their own neighborhood benefit even more from this, since the purchase decision happens in minutes. The article on hyperlocal marketing shows how to combine WhatsApp with your Google profile to be found by people nearby.
When the free tools aren't enough anymore
These five settings solve a lot, but they have a limit: the automatic reply doesn't understand the question, it only responds to a trigger. As conversation volume grows, the next step is a service that understands what the customer wrote and actually checks your catalog.
At that point, a rule catches many businesses off guard: as of January 2026, Meta bans general-purpose assistants on business WhatsApp, and the number can be blocked. The article on the new WhatsApp AI rule explains what's allowed, and the one on how much an AI chatbot costs helps you decide if it's time.
How we work
In our AI chatbot projects, the first step is always the same: look at what WhatsApp Business's free tools already solve. Many businesses don't need a bot at all — they need well-written quick replies and an up-to-date catalog. The bot comes in when the volume exceeds what one person can handle well.
Frequently asked questions
What’s the difference between WhatsApp and WhatsApp Business?
WhatsApp Business is Meta’s free app for companies. It comes with a business profile showing address and hours, a product catalog, a greeting message, an away message, quick replies, and labels to organize conversations. The personal WhatsApp app doesn’t have any of these tools.
How do you set up the away message on WhatsApp Business?
In the app’s Business Tools, open Away Message, turn it on, write your text, and choose when it applies: always, on a custom schedule, or outside the business hours listed in your profile. The message should let customers know when they’ll hear back from you.
When is the greeting message sent?
It’s sent automatically to anyone messaging the business for the first time, or after 14 days of no conversation. A good greeting welcomes the customer, states your typical response time, and points them to a next step, like checking out the catalog.
How do quick replies work on WhatsApp Business?
Save your canned texts under Business Tools, each with its own shortcut. During a chat, type a forward slash, /, in the message field and pick the reply from the list. Start with the five questions your business gets asked most often.
How many labels can you create in WhatsApp Business?
Up to 20 labels, each with its own name and color. A simple set usually does the job: new customer, quote sent, payment pending, order ready, and returning customer.
Can I use the same number on personal WhatsApp and WhatsApp Business?
Not at the same time. Each app needs its own number, but both can live on the same phone. If customers already know your personal number, you can move it over to WhatsApp Business and keep your chat history intact.
