How small businesses can use AI on WhatsApp for automated customer service

Receiving a message at 11 p.m. asking about delivery times could result in an immediate automated response, without the customer having to wait until the next day. Combining WhatsApp with artificial intelligence allows customer service to go beyond traditional menus and understand questions written in natural language.

For micro and small businesses, this technology provides an opportunity to organize frequent requests and reduce repetitive tasks, but implementation requires planning: it is necessary to define the scope of responses, connect the appropriate channels, and establish limits to avoid incorrect information.

First steps to build the assistant

The first step is to choose a development approach. Visual automation platforms allow services to be integrated without having to build the entire structure from scratch, while custom solutions offer greater control, although they may require specialized technical knowledge.

One option for officially connecting a bot to WhatsApp is Meta’s WhatsApp Business Platform. The platform provides an API that enables the exchange of information between systems, allowing messages to be received and automatic responses to be sent.

The assistant can be linked to an artificial intelligence service responsible for interpreting customer questions and formulating responses. Before starting, it is also necessary to configure the business account, phone number, and permissions required for integration.

Configuring responses with AI

Before connecting the services, it is important to list the types of questions the assistant should be able to answer. Business hours, payment methods, exchange policies, and product information are examples of topics that can form the initial knowledge base.

The next step is to gather the correct answers in organized documents or sources. The AI should consult this specific information instead of relying solely on the general knowledge acquired during its training.

When configuring the system, it is important to establish clear instructions about the tone of voice, permitted topics, and situations in which the system should admit that it does not know the answer. A question about a specific order, for example, can only be answered accurately if there is integration with the system that stores the purchase data.

Afterward, it is recommended to test conversations with incomplete questions, typing errors, and requests outside the scope, to identify flaws before releasing the service to the public.

Evaluation before putting the bot into operation

Automation does not eliminate the need for human oversight. Sensitive complaints, payment issues, and exceptional situations should have an option to be forwarded to a real agent.

The company also needs to protect customers’ personal data, control who can access the information, and comply with applicable legislation, including the General Data Protection Law (LGPD)

Another important point is to calculate the costs involved. In addition to any charges from the AI tool and the automation platform, official WhatsApp integration may involve fees per message and services contracted from third parties.

Starting with a limited set of functions helps evaluate the quality of responses, response time, and customer satisfaction. With the results in hand, it becomes easier to decide which tasks can be automated and which need to remain under the team’s responsibility.
