WhatsApp AI sales agent.
Answer, show products and take orders on your own number.

Most sales on WhatsApp start with a question: the price, a size, a photo, whether you deliver. A buyer who waits an hour for the answer has often bought somewhere else. A sales agent answers every one of those questions straight away, at night and on weekends too, from the information you give it.

Wapzen links the WhatsApp number you already use as a device, so your phone keeps working and you can still reply yourself. There’s no Meta API key and no card, and the AI is included.

It suits online stores, Instagram sellers, shops, boutiques and service businesses with a price list. To see how it works behind the scenes, read what a WhatsApp chatbot is.

A menu bot still works for one narrow job, such as “press 1 for tracking”. But buyers rarely ask in menu shape. They write “do you have this in blue, and can it come by Friday?”, and an agent can answer both parts at once.

The agent answers only from what you give it. If a product, price or offer isn’t in its information, it says so instead of guessing, so keep your list up to date.

• The price list is what it reads. Names, sizes or variants, prices, offers and delivery rules. A clear list gives better answers than a designed brochure.
• Images & Files is what it sends. Photos go as WhatsApp photos and PDFs as documents, when the buyer’s message matches the note you wrote.
• Your website is a backup. The agent reads pages on your own site. Pages that only appear after a lot of JavaScript loads may not be readable, so check its answers.
• It doesn’t read the catalog inside the WhatsApp Business app. Put the same products in its price list instead.
• Scanned PDFs can’t be read. Use a file with selectable text, or type the products in.

Here’s how a sale could go at a made-up clothing store:

Add a number under Order alerts on WhatsApp and each new or changed order is sent there, so whoever packs orders sees it without opening the dashboard. For more on this flow, read the WhatsApp order-taking chatbot guide.

On the official WhatsApp Business API, a business can reply freely within 24 hours of the customer’s last message. After that, it can only send a pre-approved template, and Meta charges for it. That’s how API platforms send automatic follow-ups, and why they usually cap them: MaviBot, for example, allows at most two per conversation.

With Wapzen, follow-up works like this:

1. Check who didn’t buy. On the Conversations page, open the chats that ended with a question or a price and no order.
2. Send one short follow-up yourself, from the dashboard or your phone, with a reason to reply.
3. Let the agent take it from there. When the buyer answers, the agent replies with the whole conversation in mind and can take the order.

Follow-up messages that get answers are short, personal and give a reason:

• “Hi Priya, the white linen shirt you asked about is back in size L. Shall I put one aside for you?”
• “Hi Sam, did the price list come through? Happy to help you choose the sofa size.”
• “Hi Ana, the two-for-$70 offer ends on Sunday. Would you like me to put your order together?”

WhatsApp’s Business Messaging Policy asks businesses to message only people who gave them their number and agreed to hear from them. Follow up with buyers who wrote to you, once or twice at most, and stop if they say no.

Pick the three or four questions your best salesperson always asks. For a furniture store, they might be:

• Which room and what size of space?
• Budget range?
• Delivery city or area?
• When do you need it?

Then add a rule such as: “When you have all four answers, recommend up to three products from the list and say a team member will contact them with a quote.” You can also have Take Order record each qualified enquiry as an order with those details, so they appear on your Orders page. Test that from another phone before relying on it.

• Write the hand-over rules in its instructions, so it tells the buyer a person will reply instead of improvising.
• Agree who checks the chats, and how often, during business hours.
• Your own replies stay in the conversation. When you switch the AI back on, it knows what you said.

These instructions are for a made-up clothing store. Change them to yours:

You are the virtual assistant of Demo Threads, an online clothing store.
Say in your first message that you are a virtual assistant.
Reply in the customer's language. Use two or three short sentences and ask one question at a time.
Use only the products, sizes, prices, offers and delivery rules you were given. If something isn't listed, say so. Never invent prices, discounts, stock or delivery dates.
When a customer isn't sure what to buy, ask what it's for and their size or budget, then suggest two or three products from the list with their prices.
When a customer wants to see a product, send its photo from your files.
You may suggest one matching item once per conversation, and only from the list.
Offer only the discounts listed. If a customer asks for a bigger discount, say a team member will reply.
To take an order: ask for the items, sizes and quantities, the delivery address and the payment method. Repeat the order with each price, the delivery charge and the total, and place it only after the customer confirms.
After placing an order, share the payment link. Never say a payment has been received: say our team will confirm it.
For complaints, returns, wholesale orders and anything you can't answer, say a team member will reply on this chat.

• One suggestion, not a hard sell. An agent told to upsell on every message annoys buyers. One matching item, once, is plenty.
• Name the discounts. If an offer isn’t written down, the agent won’t give it, which is what you want.
• Test it like a difficult buyer. Ask for a bigger discount, send a voice note, change your mind about the size, and check each answer.

• A link that starts the conversation. Make one free with our WhatsApp link generator, with a message such as “Hi, I’d like to see the new collection”.
• A QR code on receipts, packaging and your counter, from our WhatsApp QR code generator.
• Prices up front. Buyers on WhatsApp ask the price first. An agent that answers with the price and a photo keeps them talking.
• Fewer choices. Two or three picks that match what the buyer said sell better than sending the whole catalog.
• Close in the chat. Confirm the order and send the payment link in the same conversation, instead of sending the buyer to a website.
• Follow up once, with a reason, as in the examples above.

Choose an API platform if you need a green tick, marketing campaigns or automated follow-up sequences, and are ready for the API setup and per-message costs. Try Meta Business Agent if it’s available for your account. Choose Wapzen if you want an agent on your current number today that answers, shows products and takes orders. Our guide to Meta Business Agent covers it in detail.

• Meta Business Agent in the app: free to start; Meta has said businesses will reach it through paid subscriptions.
• Meta Business Agent Platform on the API: $2.00 per million tokens since 1 August 2026.
• API platforms: a plan, AI credits or an AI add-on, and Meta’s charges. Since 1 October 2026, Meta also charges for service replies beyond the first 1,000 a month per number.
• Wapzen: free to start. It doesn’t use the API, so there are no Meta per-message charges.

Meta changes its rates every quarter, so check its pricing page before you compare bills.

Some buyers would rather call than type, especially for bigger purchases. The voice agent can answer questions about your products, prices and delivery, and the chat agent then takes the order in writing, where it’s confirmed and saved.

1. Write your instructions first. The agent starts answering as soon as the number is linked.
2. Sign up free. No card and no API key.
3. Link the number. In WhatsApp: Linked devices › Link a device › Link with phone number instead, and enter the code. On a computer you can scan the QR code.
4. Add your products: the price list in the Knowledge Base, photos and PDFs in Images & Files, and your website on the Web Search card.
5. Switch on Take Order, write your order instructions and add the number for order alerts.
6. Test it as a buyer from another number: ask for a photo, send a voice note, ask for a discount, place an order and change it.

• Live stock or order tracking: if your store software has a public API, an API tool can look things up during the chat. That needs someone technical.
• It works on your current number, personal or WhatsApp Business, as a linked device.
• Wapzen is an independent product, not made by Meta or WhatsApp.
