WhatsApp chatbot for online store: automate sales, orders, and follow-ups

Someone messages your store on WhatsApp asking if a product is available in their size. It's 11pm. You're asleep. By morning they've already ordered from someone else.

This happens constantly for store owners who rely on WhatsApp to sell but still handle every message by hand. The channel works. The volume doesn't.

A WhatsApp chatbot fixes this. MaviBot answers product questions, takes the order, and processes payment, all inside WhatsApp, without you touching the conversation. Sales happen while you sleep. Follow-ups go out automatically.

Below is what a WhatsApp store chatbot actually does and how to set one up with MaviBot in five steps.

Why WhatsApp works for online stores

Email newsletters get opened 20% of the time on a good day. WhatsApp messages get opened 98% of the time, usually within minutes. For stores that already have customers on WhatsApp, this isn't a new channel. It's a better version of the one they're already using.

The limitation has always been capacity. One person can handle 20 WhatsApp conversations a day. At 200, something breaks: response times slip, questions get missed, sales fall through.

A WhatsApp chatbot handles the volume without adding staff:

• Instant replies at any hour, so no lead goes cold because it arrived at midnight
• Consistent product information, meaning every customer gets the same accurate answer about specs, pricing, and availability
• Payment inside the chat, with no redirect to a website and no abandoned checkout waiting for a payment link
• Automatic follow-ups for cart abandonment, shipping updates, and re-engagement

Stores using MaviBot report handling 5-10x more customer conversations without adding staff, and closing more sales because response time drops from hours to seconds.

What your WhatsApp store bot handles automatically

Product questions and catalogue browsing

Customers ask the same questions before every purchase: Is this available in blue? Does it come in XL? What are the dimensions? Is it in stock?

MaviBot's RAG AI Assistant answers every product question automatically, based on the information you upload. Add your catalogue, descriptions, and specifications once. The AI handles every question accurately, in the customer's language, around the clock. Customers get the answer they need. You don't get interrupted.

For stores with structured catalogues, MaviBot can present products as interactive message cards (image, name, price, short description) so customers browse and select without leaving WhatsApp.

Order taking inside the chat

When a customer is ready to buy, the entire order process happens in the same WhatsApp conversation. They select the product, choose variants (size, colour, quantity), and confirm their delivery details through a guided chatbot flow.

No website visit required. No form to fill out in a browser. The order lands in MaviBot's CRM with the customer's full details, product selection, and delivery address, ready to fulfil.

Payment processing without leaving WhatsApp

MaviBot supports 20+ payment gateways: Stripe, PayPal, Mercado Pago, PayTabs, Fondy, and others, each available as a payment button inside a WhatsApp message. The customer taps the button, pays on a secure gateway-hosted page, and the confirmation comes back into the chat automatically.

For markets across Latin America, the Middle East, and Africa, where WhatsApp is already the primary commerce channel, this means completing the full purchase cycle without ever leaving the app. Accepting payments in a chatbot is one of the most direct conversion improvements an online store can make.

Abandoned cart recovery

A customer browses your products, asks questions, starts the order flow, then goes quiet. Without automation, that sale is gone.

MaviBot sends an automatic follow-up after a set interval: a reminder of what they were looking at, a gentle nudge, sometimes a limited-time offer. Abandoned cart recovery on WhatsApp outperforms email because the message lands in a channel the customer actually checks.

Order confirmations and shipping updates

The moment an order is placed and paid, MaviBot sends a confirmation with the order details. When the order ships, another message goes out with tracking information. When delivery is confirmed, a follow-up asks for a review or surfaces a related product.

Every post-purchase touchpoint runs automatically. The customer feels looked after, and you never had to send a single manual message.

How to set up a WhatsApp chatbot for your online store

The full setup takes under an hour. No developer, no code.

Step 1: Connect your WhatsApp Business account

In MaviBot, go to Channels and connect your WhatsApp Business account via the WhatsApp Business API. This is the official Meta integration. Your number stays yours, and you get access to broadcast messaging, chatbot automation, and the full API feature set.

If you don't yet have a WhatsApp Business API number, MaviBot walks you through the setup process. The connection takes about 10 minutes.

Step 2: Build your product flow

In MaviBot's chatbot builder, create your product discovery flow. This is the conversation a customer has when they first message your store.

Two approaches, depending on your catalogue size:

For smaller catalogues, build a structured menu: categories, products, variants. The customer taps through options, selects what they want, and the bot moves them to checkout automatically.

For larger catalogues, use MaviBot's RAG AI Assistant. Upload your product catalogue as a document or connect your product data. The AI answers any product question naturally ("Do you have leather wallets under $50?") and surfaces the right product without the customer navigating a rigid menu.

Both approaches store the customer's selection as variables in the CRM (product name, variant, quantity) ready to pass into the order flow.

Step 3: Connect your payment gateway

In MaviBot's Acquiring settings, connect the gateway you use. MaviBot supports:

• Stripe for global stores
• PayPal for international customers
• Mercado Pago for Brazil, Argentina, Mexico, Colombia, and other Latin American markets
• PayTabs for the Middle East and North Africa
• Fondy and others for Europe and CIS markets

Once connected, add a payment button to your checkout step in the chatbot builder. When a customer reaches that step, they tap the button, pay, and confirmation returns to the chat automatically.

Step 4: Set up post-purchase automation

In MaviBot's chatbot builder, configure what happens after payment:

• Confirmation message sent immediately with order summary and expected delivery
• Shipping update triggered when you mark the order as shipped in the CRM
• Delivery follow-up sent 1-2 days after expected delivery, asking for feedback or offering a related product
• Re-engagement sent 30 days after purchase to customers who haven't ordered again

Configure each message once. From that point, every order triggers the sequence automatically for every customer, every time.

Step 5: Activate broadcast for new products and promotions

MaviBot's Campaigns feature lets you send WhatsApp broadcasts to your customer list: new product announcements, flash sales, restocked items, seasonal offers.

Unlike email, WhatsApp broadcasts land in the app your customers check most. Segment your list by purchase history, product category, or location and send targeted messages that are actually relevant. WhatsApp broadcast consistently outperforms email for open rates, click rates, and conversion on promotional messages.

WhatsApp store chatbots by business type

Fashion and clothing: size guides, availability checks, styling suggestions. The AI handles the "does this run small?" questions that slow down every sale. New collection launches go out as broadcasts to your full customer list.

Food and beverage: menu browsing, order taking, delivery time estimates, and payment in one conversation. For restaurants and meal prep services, the WhatsApp chatbot replaces manual order management entirely.

Beauty and cosmetics: shade matching, ingredient questions, routine recommendations. The RAG AI answers detailed product questions accurately, cutting returns and building confidence at the point of purchase.

Digital products and courses: the full purchase and delivery cycle happens in one WhatsApp conversation. The customer pays, receives the download link or course access automatically, with no manual work required.

Handmade and custom products: a qualification flow captures the customer's requirements (size, material, personalisation), confirms the order details, and takes a deposit, all before any human gets involved.

Frequently asked questions about WhatsApp chatbots for online stores

Can the chatbot handle orders for a store with hundreds of products?

Yes. MaviBot's RAG AI Assistant is built for exactly this. Upload your full product catalogue once and the AI can answer any question about any product: availability, variants, pricing, specifications, comparisons. Customers don't navigate a menu; they ask naturally and get accurate answers. The AI handles follow-up questions in the same conversation too.

Which payment methods can customers use inside WhatsApp?

Any method your connected gateway supports. Stripe covers cards, Apple Pay, and Google Pay. Mercado Pago covers local payment methods across Latin America including Pix (Brazil), PSE (Colombia), and OXXO (Mexico). PayTabs covers cards and local methods across the Middle East. The customer taps the payment button in WhatsApp and completes the transaction on the gateway's secure page, with no account or app installation required.

What happens if a customer asks something the bot can't answer?

MaviBot escalates to a human automatically. The conversation gets flagged in MaviBot's unified inbox, where you or a team member can step in and reply directly. The customer gets a message that a team member will be with them shortly. You set the escalation threshold yourself, so routine questions stay with the AI and only genuinely complex requests reach your team.

Can I use the chatbot on Instagram and my website as well as WhatsApp?

Yes. MaviBot connects WhatsApp, Instagram, Facebook Messenger, Telegram, and a website chat widget from the same platform. Build your product flow once and it runs across every channel. Orders, customer data, and conversation history all flow into the same CRM, managed from one dashboard.

Do customers need to install anything to shop via the WhatsApp chatbot?

No. The entire experience happens in the WhatsApp app the customer already has on their phone. Nothing to download, no account to create, no website to navigate. Your store is already on your customer's phone.

Your store, running 24/7

Every message your store receives is a potential sale. Whether you close it usually comes down to response speed.
