Chat Commerce: What It Is, Why It Is Growing, and How to Sell 100% Through WhatsApp
What chat commerce is, why it is growing in Brazil, and how to turn WhatsApp into a complete sales channel without redirecting the customer.
Consumer behavior has changed. They no longer want to open a website, browse categories, create an account, add to cart, and only then complete the purchase. They want to resolve everything from where they already are, and where they already are, most of the time, is WhatsApp.
This is the context in which chat commerce emerges: the sales model where the entire purchase journey happens inside a conversation, with no redirects, no apps, and no friction.
In this article, we explain what chat commerce is, why it is growing in Brazil and worldwide, and how companies are already using this approach to increase conversion and reduce operational cost.
What Is Chat Commerce
Chat commerce is the e-commerce model performed entirely within messaging platforms (such as WhatsApp, Telegram, or Instagram Direct) without the customer needing to leave the chat to complete a purchase.
In practice, this means that in a single conversation the customer can:
- Discover a product or service
- Get answers with AI-powered automated service
- Check prices, availability, and conditions
- Choose what they want
- Pay via PIX, bank slip, or card
- Receive confirmation and order updates
All without opening a browser, downloading an app, or creating an account on a new website.
Why Chat Commerce Is Growing
WhatsApp is Brazil’s highest-engagement channel
Brazil has more than 170 million active WhatsApp users. The app is installed on 99% of Brazilian smartphones and is checked, on average, more than 30 times a day by each user. No other digital channel (not email, not websites, not apps) has this level of presence and frequency of use.
Consumers do not want to download more apps
Research shows that more than 70% of users abandon the purchase process when they are required to download an app. App commerce had its peak, but the reality is that consumers are tired of installations. WhatsApp is already on the phone, and chat commerce takes advantage of exactly that.
Email has lost relevance
Email marketing open rates have fallen to less than 20% on average. WhatsApp, on the other hand, has message open rates above 90%. For companies that need to communicate with customers efficiently, the comparison is stark.
AI made service scalable
Until recently, chat commerce had an obvious limitation: it required human agents to respond to messages. With the evolution of artificial intelligence models, that changed. Today it is possible to automate 90% or more of interactions (answers to frequently asked questions, product presentation, order data collection, payment processing) without human intervention, 24 hours a day, 7 days a week.
Native checkout eliminates abandonment
One of the biggest problems in traditional e-commerce is cart abandonment, which reaches 70% on average. Much of this abandonment happens at the moment of redirect to checkout. In chat commerce, payment happens inside the conversation, with no context switch. Purchase completion rates are significantly higher.
Chat Commerce Worldwide
Chat commerce is not a trend exclusive to Brazil. In China, the model has been established for years: platforms such as WeChat Pay process trillions of dollars in transactions inside the chat. In India and Southeast Asia, the WhatsApp Business API is turning informal retail into structured digital operations.
In Brazil, the movement is accelerating. Companies across different segments (retail, transportation, industry, events) are migrating part or all of their commercial operation to WhatsApp.
How Chat Commerce Works in Practice
1. The customer initiates contact
The customer sends a message to the company’s number, whether through a QR Code, direct link, button on the website, or ad on Instagram and Facebook.
2. AI takes over service
An AI-powered chatbot receives the message and responds immediately, identifying the customer’s intent and directing them to the appropriate flow: purchase, question, support, order inquiry.
3. The customer browses the catalog
Inside the chat, the customer can view products, check prices, see availability, and compare options, all interactively, without leaving the conversation.
4. The order is placed
The customer chooses what they want. The system automatically collects the necessary information (address, quantity, variations) and confirms the order.
5. Payment happens in the chat
A payment link or native form is sent inside WhatsApp. The customer pays via PIX, card, or bank slip without opening another app.
6. ERP integration processes the order
Automatically, the order is registered in the company’s management system (ERP, CRM, inventory system) without manual intervention.
7. The customer receives updates
Payment confirmation, delivery estimate, invoice: everything arrives through the same channel, automatically.
Which Segments Already Use Chat Commerce in Brazil
Transportation and mobility
Bus terminals and transportation companies were among the first segments to adopt chat commerce in Brazil in a structured way. Ticket sales through WhatsApp, integrated with ticketing systems, allow passengers to check schedules, choose seats, and pay, all in the chat.
TeaserMe case: at Rodoviária de Porto Alegre, sales through WhatsApp became the leading channel compared to the website. Customer service was automated at 92%, and the service team was reduced from 12 to 4 people.
Retail
Stores across different segments (fashion, electronics, food, pet shops) are using chat commerce to close sales that were previously lost to cart abandonment in traditional e-commerce.
Events
Ticket sales, credentialing, programming, and support during the event: all through WhatsApp, with no app and no queue.
Industry and B2B
Industrial companies are using chat commerce for replenishment orders, inventory inquiries, duplicate invoice requests, and supplier service, reducing phone calls and unanswered emails.
Chat Commerce vs Traditional E-Commerce
| Criterion | Traditional e-commerce | Chat commerce |
|---|---|---|
| Channel | Website or app | |
| Registration required | Yes | No |
| Abandonment rate | ~70% | Much lower |
| Service | Asynchronous (email/external chat) | Immediate and integrated |
| ERP integration | Via platform | Via real-time API |
| Personalization | Limited | High (individual conversation) |
| Channel acquisition cost | High (SEO, ads) | Lower (WhatsApp already installed) |
What Is Needed to Implement Chat Commerce
To implement chat commerce professionally and at scale, your company needs:
1. Official WhatsApp Business API Real chat commerce is not possible with the WhatsApp Business App (the free phone version). The official API is the only path to automation, integration, and scale.
2. A Meta Tech Provider API access requires a partner approved by Meta. This partner provides infrastructure, integration, and technical support.
3. Automation and AI platform The heart of chat commerce is intelligent automation: a system that understands customer intent, conducts the conversation, and processes the order without human intervention.
4. Integration with management systems For an order placed on WhatsApp to be processed automatically in the ERP, CRM, or inventory system, API integration is required.
5. Integrated payment gateway Checkout inside the chat requires a payment gateway that supports integration with the chat commerce platform.
Why TeaserMe Is a Pioneer in Chat Commerce in Brazil
TeaserMe was created with a single goal: to perform 100% of sales and service operations inside the chat. While the market was still debating whether WhatsApp could be a sales channel, TeaserMe was already building the infrastructure to make it happen.
In 24 months of operation, the company has accumulated more than 200 delivered projects, serving clients such as Mercado Livre, Hyva, Expresso Embaixador, Rodoviária de Porto Alegre, and CIC de Bento Gonçalves.
As an official Meta Tech Provider, TeaserMe has direct access to the WhatsApp API and native integration with the main ERPs on the market (SAP, TOTVS, Oracle) and payment gateways such as Asaas, Cielo, and PagSeguro.
The result for clients is direct: more sales, lower operational cost, and a purchase experience that consumers prefer.
Conclusion
Chat commerce is not the future: it is the present. Companies that still treat WhatsApp as a support channel are leaving revenue on the table and losing to competitors that already sell, serve, and retain customers 100% inside the chat.
The technology is available, the consumer is ready, and the market is moving. The question is no longer “if” chat commerce will consolidate, but “when” your company will be part of it.
