WhatsApp Chatbot for Online Sellers in Vietnam: Take Orders, Payment and Delivery in Vietnamese in the Chat
AeroChat is a WhatsApp chatbot that takes a Vietnamese seller’s order from first question to delivery. It answers stock, price and shipping questions in Vietnamese from your store or your Google Sheet. It takes the order, sends a payment link or confirms cash on delivery, detects the payment and books the shipment, all in the same chat. It runs on Messenger, Instagram, Telegram, TikTok Shop buyer chat and your web chat too.
Many Vietnamese sellers run a home business or a small brand through chat. Buyers find you on Facebook, TikTok, Instagram or a marketplace, then message you. The questions repeat all day: “Còn hàng không shop?” (still in stock?), “Giá bao nhiêu?” (how much?), “Ship mấy ngày?” (how many days to ship?), “Có COD không?” (cash on delivery?). Sellers answer by hand, check transfer screenshots and copy orders into a sheet. AeroChat answers from your real stock and prices and finishes the sale in the chat.
What AeroChat does for a Vietnamese online seller
- Answers from your real data. Products, prices and stock come from Shopify, WooCommerce or Wix, or from a Google Sheet if you don’t have a store yet.
- Replies in Vietnamese, politely. It replies in the customer’s language, addresses them as anh or chị, uses dạ and ạ, and reads messages typed without tone marks. See AI customer service in Vietnamese.
- Takes the order in the chat. It collects the items, the name, phone number and full address, and records the order.
- Takes payment. It sends a payment link and detects the payment automatically, so nobody checks a transfer screenshot. Airwallex is built in. If you already use 2C2P, it connects through its API. The payment methods the customer sees depend on what your account offers.
- Confirms cash on delivery orders before you pack them. See cash on delivery confirmation in Vietnam.
- Books the delivery with DHL eCommerce, or same-day with Lalamove or GrabExpress, and sends the tracking number.
- Understands voice notes. Voice notes are transcribed, so a spoken order works too.
- Passes the chat to you when it should. Anything outside your rules, such as a wholesale order or a complaint, goes to you with the details.

In your Google Sheet: a new order row is added with the coffee, the address and “COD 390.000đ”.
Copy this into AeroChat
When a customer wants to buy on WhatsApp, follow these steps.
- Check the product and stock in our Products sheet (example) and tell them the price in dong.
- Ask for their name, phone number and full address with house number, alley, ward and city or province, and read it back.
- Ask if they want to pay now or cash on delivery.
- If they pay now, add the order to our Orders sheet and send a payment link for the total. When the payment comes through, mark the order “Paid”.
- If they choose cash on delivery, add the order as “COD” and confirm the total and address with them before anything ships.
- When we mark the order packed, create the shipment with our courier, as COD with the total if it is unpaid, and send the tracking number.
- If they ask for wholesale prices or a large order, pass the chat to me.
Reply in the customer’s language. In Vietnamese, address the customer as anh or chị and use dạ and ạ.
Change the sheet names, prices, forms of address and courier to your own before you paste it.

Questions
Do I need a website to use it?
No. You can sell from a Google Sheet with your products and orders. When you outgrow it, connect Shopify, WooCommerce or Wix.
Does it work on Messenger and Zalo?
Messenger, Instagram, WhatsApp, Telegram and web chat run the same workflows from one dashboard today. Zalo is on AeroChat’s list of channels coming next.
What does each WhatsApp message cost?
Customer messages are free. Meta charges per delivered business message, and Vietnam falls under Meta’s “Rest of Asia Pacific” rate, as of November 2026. See WhatsApp pricing. AeroChat plans are on the pricing page.
Can it handle a livestream rush?
Yes. AeroChat answers every chat at once, so when a livestream or a Tết promotion brings a wave of “còn hàng không?” messages, each buyer gets the stock and price straight away.
Using a different system? If it has a public API, it connects to AeroChat the same way: describe what you want, paste in its key, and it runs.
