What does an AI agent do on your business WhatsApp?
It answers your customers instantly, at any hour, with your business information: products, prices, hours and policies. It recommends, sends photos, takes orders or books appointments, understands voice notes and saves each customer's details. When a person is needed, it hands the chat to your team with a summary. All on your same number, through the official WhatsApp API.
- Replies in seconds, day and night, weekends included.
- Sells: knows your catalog and current prices and sends the product photo.
- Takes orders, books appointments and qualifies every customer for you.
- Hands the chat to a person when the conditions you set are met.

What businesses ask for most
- Reply instantly at any hour. No customer waits until tomorrow or leaves for a competitor because nobody answered.
- Sell with your catalog. It searches your products or services, gives the current price, recommends options and sends the photo. Change a price and it uses the new one from the next message.
- Take orders and book appointments. It collects what the customer wants, their details and address, or books the appointment, so nobody on your team has to copy anything by hand.
- Understand voice notes and photos. Many customers send voice messages or a picture of what they want: the agent understands them and replies.
- Hand the chat to your team. You decide when: a complaint, a big sale, a sensitive topic. The agent pauses and your rep gets a summary so they don't ask everything again.
- Save details and qualify the customer. It records name, city, interest and what the customer says, tags them and moves them through your sales pipeline so you know who to call first.
How does it know the answers?
It answers with the information you give it: your catalog, documents (even long PDFs such as manuals or price lists) and the pages of your website. It's set up not to make up prices, hours or terms: if something isn't in your information, it says so or hands the chat to a person.
It also keeps the conversation on topic. If someone tries to use it for something else, it steers back to what your business offers.
What you control
- You see every conversation and can reply yourself from the shared inbox, with your team.
- You choose the tone: friendly or formal, with short or more detailed answers.
- You set a monthly AI spending cap, so the cost never runs away.
- The agent improves over time: real conversations are reviewed to find the questions it couldn't answer and fix them.
- It can reply in Spanish, English or Portuguese.
Menu chatbot or AI agent: the difference
| Menu chatbot | AI agent | |
|---|---|---|
| How the customer talks | Picks options: "type 1, 2 or 3" | Types or sends a voice note as they would to a person |
| Questions outside the menu | Doesn't understand them | Answers them with your information |
| Selling | Shows a fixed list | Recommends based on what the customer wants and gives the price |
| Orders and appointments | Step-by-step form | Collects it in the conversation and leaves everything ready |
| When it hands off to a person | When the customer picks "agent" | When the conditions you set are met |
An AI agent can also use WhatsApp buttons and forms when it helps, for example to pick an appointment time.
Examples by type of business
- Online stores and retail: answers about sizes, colors, shipping and payment methods, and sends the product photo.
- Restaurants and delivery: takes the order with the address and leaves it ready for the kitchen.
- Clinics, aesthetics, dental and barbershops: answers questions about services and prices and books the appointment.
- Real estate: asks what the client is looking for, budget and area, and passes serious leads to an agent.
- Education and professional services: explains programs or services, qualifies each lead and books the call.

What it doesn't do (worth knowing)
- It doesn't send bulk messages to people who didn't give permission: to message first, Meta-approved templates are used.
- It doesn't replace your whole team: it handles the repetitive work and passes on what needs human judgment.
- It isn't a "ChatGPT on WhatsApp" for any topic: it's your business's service and sales agent, which is what Meta allows.
- It isn't perfect on day one: it's tuned with your real conversations during the first weeks.
Does Meta allow AI on WhatsApp Business?
Yes, to serve your business's customers. Since January 15, 2026, Meta's terms prevent an AI provider from offering its assistant as the main product on the WhatsApp API (the typical "ChatGPT on WhatsApp"), but they allow a business to hire an AI provider to serve its own customers. This is general information, not legal advice.

What is a WhatsApp AI agent?
It's an artificial intelligence assistant connected to your business WhatsApp that talks with your customers the way a person would: it answers questions with your information, recommends products, takes orders or books appointments, and hands the chat to your team when needed.
Can an AI agent sell on WhatsApp?
Yes. It searches your catalog, gives the current price, recommends options based on what the customer asks, sends the product photo and leaves the order or appointment ready. Your team closes whatever needs a human touch.
Does it understand voice notes?
Yes. It understands the voice notes and photos your customers send and replies in writing.
Can it make up prices or information?
It's set up to answer only with your information: catalog, documents and website. If something isn't there, it says so or hands the chat to a person. And you see every conversation to fix whatever needs fixing.
Do I have to change my number?
It isn't required: with coexistence you can connect your same number and stay on the WhatsApp Business app. But we recommend a number for the API only, without coexistence, because it lowers the risk of a ban.
How much does a WhatsApp AI agent cost?
With AivaChat, implementation by our team starts at USD 500 as a one-time payment plus the USD 49 a month platform. WhatsApp messages are billed separately by Meta, depending on the country. The final price is set on a free discovery call.
