Sales on WhatsApp

AI agent for sales: answers, asks what's missing and follows up with whoever vanished

Quick answer

What does an AI agent for sales do?

An AI agent for sales answers whoever arrives on WhatsApp, asks what the person needs, explains the service and the price and follows up with whoever stopped replying. Each prospect becomes a deal in the CRM pipeline. The close that depends on negotiation stays with you, and you receive the conversation ready.

Most of the sales lost on WhatsApp are lost in silence: the customer asks the price, nobody continues the conversation and they disappear. The agent answers, asks what's missing and re-engages whoever stopped.

Where the sale is lost, and what the agent does

Four moments when the prospect disappears, and how each is handled.

01

Unanswered question

The prospect writes on Sunday night. The agent answers right away, and they don't need to look for someone else.

02

Price with no conversation

After the price comes a question, to keep the conversation going: what the person needs, by when, for how many.

03

Customer who vanished

Follow-up goes out on its own to whoever stopped replying, at the interval you set.

04

Sale with no record

Each prospect becomes a deal in the pipeline, with the stage they're at and the next task.

How to put the agent to sell

What they need to know is what you already answer every day.

  1. Teach the business to the Brain

    Services, prices, hours, rules and what you would rather nobody answer. The Brain is the knowledge base that makes the agent answer like your company, and not like a generic robot.

  2. Connect the number you already use

    By QR code or through Meta's official signup. CertuAI is a Tech Provider of the Meta WhatsApp Business Platform, and the number stays yours: the plan gives you the connection slot, not a new number.

  3. Follow along in the CRM and take over whenever you want

    Each conversation shows up in the dashboard with a contact, a deal and a task. You step into the same conversation at any time, and the agent hands the topic back to you when it falls outside what it learned.

What the agent does in the sale and where it stops

It handles the start and middle of the conversation. The end is yours.

Sell more without answering more messages

The agent works with people who already sought out your company: the person who clicked the ad, found the number on Google or was referred. It doesn't blast messages to a list of strangers.

The pipeline stages are yours. You set the names, and the conversation moves from one to the next as it progresses. If the company has departments, each with its own person in charge, the agent identifies the topic and notifies the right person.

Frequently asked questions

Does the AI agent close the sale on its own?

It takes the conversation up to the point of closing: it answers, asks what's missing and books a time when the sale goes through a visit or appointment. Price negotiation and terms outside the rules stay with you.

Does the agent do customer prospecting?

Not on a cold list. It answers and re-engages people who have already contacted your company. Follow-up is for those who talked and stopped replying.

How does automatic follow-up work?

When the customer stops replying, the agent sends a new message after the interval you set, up to the limit you choose. If the person replies, the conversation continues normally.

Can the agent give discounts?

Only what is written in the company's information. Beyond that it promises nothing and hands the conversation to you.

How much does an AI agent for sales cost?

At CertuAI, from US$ 75 per month on Start, with 1,600 AI replies, automatic follow-up and CRM.
