How a Bus Terminal Automated 92% of Customer Service and Opened a New Sales Channel on WhatsApp

Rodoviária de Porto Alegre is one of the busiest bus terminals in southern Brazil. Passenger service volume is high and constant — schedules, prices, cancellations, refunds, boarding information.

For years, this service worked like most terminals across the country: staff at the counters, phone lines, and an informal WhatsApp presence that depended on available agents and business hours. The result was predictable: a backlog of messages, unanswered requests outside business hours, lost sales, and an expensive operation to maintain.

The Challenge: Serving More Without Growing the Team

The main bottleneck was not a lack of demand — it was a lack of service capacity at the right scale. Today’s passenger doesn’t call. They send a message. And when they don’t get a fast response, they look for the ticket through another channel — or give up on the trip altogether.

The team had to handle a growing volume of repetitive messages: what time is the bus to Florianópolis, can I cancel my ticket, how do I reschedule. Simple questions that consumed the time of agents who could have been focused on situations that truly require human judgment.

The solution needed to solve two problems at once: reduce the operational load of customer service and open a sales channel that worked autonomously, 24 hours a day.

The Solution: WhatsApp as the Official Sales and Service Channel

TeaserMe’s implementation turned Rodoviária de Porto Alegre’s WhatsApp into two products in one:

Autonomous service channel: AI began answering frequently asked questions about schedules, prices, cancellation policies, and boarding without human intervention. In cases where the passenger needs personalized support, the conversation is escalated to a human agent with the full conversation history available.

Ticket sales channel: integrated directly with the terminal’s management system, WhatsApp now lets passengers check schedules, choose their trip, select a seat, and complete payment — all within the conversation, without leaving the app.

How the Passenger Journey Changed

Before, buying a ticket through WhatsApp meant sending a message and waiting for an available agent to type out the options, send a payment link, and manually confirm the purchase. The process depended on staff availability and business hours.

With the solution in place, the passenger starts a conversation on the terminal’s official WhatsApp, the AI identifies their intent, presents options in real time, the passenger chooses the schedule and seat, pays via PIX or card inside the conversation itself, and receives the electronic ticket automatically in the chat. All of this without human intervention, at any hour of the day or night.

The Results

The most telling number: 92% of interactions are now resolved autonomously by AI, with no need for human intervention. This led to a significant reduction in the size of the team dedicated to WhatsApp service.

The second key result was the opening of a new revenue channel. WhatsApp began generating ticket sales from a customer base that previously didn’t buy through the traditional website — passengers who prefer the convenience of the app they already use every day.

Why the Model Works in the Transportation Sector

Repetitive, standardized requests — most passenger questions follow predictable patterns, making AI automation highly effective.
Low-complexity purchase decisions — the passenger knows what they want and just needs an easy channel to buy.
A customer base that already uses WhatsApp — in Brazil, 99% of phones have the app installed.
24-hour operation — with AI operating autonomously, the channel works outside business hours.

The Role of Integration with the Management System

The difference between a bot that only answers questions and a true autonomous sales solution lies in integration with the management system. In the case of Rodoviária de Porto Alegre, TeaserMe integrated with the terminal’s operating system, allowing WhatsApp to check availability, prices, and schedules in real time and process the sale directly in the system, generating the electronic ticket with no manual steps.

Conclusion

What the numbers show is that the combination of conversational AI, integration with the management system, and the official WhatsApp API creates an operation that is both more efficient and more profitable. For bus terminals and transportation companies that still operate WhatsApp manually, the path forward is already proven.
