In markets like Bangladesh, customers often prefer to ask questions and confirm orders on WhatsApp. Used well, it increases trust and reduces failed cash-on-delivery orders.
From my own work: I build WhatsApp automations for stores, including COD confirmation flows. Confirming each COD order before dispatch is one of the simplest ways to cut returned parcels.
1. Set up a proper business profile
Use the WhatsApp Business app with your logo, address, hours, website and a short description. Add away messages and a greeting.
2. Add a catalog
List products with photos, prices and links so customers can browse without leaving the chat.
3. Quick replies and labels
- Save replies for price, delivery charge, payment methods and return policy.
- Label chats: New order, Confirmed, Paid, Delivered, Follow up.
4. Confirm cash-on-delivery orders
Send each new COD order a summary and ask the customer to confirm before shipping. Unconfirmed orders get a call.
5. Automate with the Cloud API
When volume grows, the Cloud API lets you send approved template messages (order confirmations, delivery updates), connect a CRM and build bots. Tools like n8n can connect it to WooCommerce.
6. Follow the rules
- Message people who opted in; respect opt-outs.
- Use approved templates for business-initiated messages outside the customer service window.
- Follow the messaging policy and avoid spam.

FAQ
Is WhatsApp Business free?
The app is free; the Cloud API charges per conversation or message type according to Meta’s pricing.
Can I send bulk messages on WhatsApp?
Only to opted-in customers using approved templates through the API; bulk spam can get numbers banned.
Can WhatsApp replace my website?
It complements a website; a site still matters for search, payments and trust.
