How to set up a WhatsApp chatbot for your business in Bangladesh

2 November 2026 · 2 min read

In Bangladesh, a lot of selling and support happens in chat. Customers ask the price, the delivery time, whether something is in stock, and they expect an answer quickly. A WhatsApp chatbot or AI assistant can answer the routine questions around the clock so your team deals only with what needs a person.

What a good chatbot should do

  • Answer the questions you hear every day: prices, opening hours, delivery areas, how to order.
  • Collect the details for an order or booking: name, phone, address, what they want.
  • Know when it does not know, and pass the conversation to a human with the context attached.
  • Speak the customer's language, in Bangla or English.

Rule-based bot or AI assistant?

A rule-based bot shows menus and fixed replies. It is predictable and cheap, but customers get stuck the moment they type something unexpected. An AI assistant understands free-form messages and answers from your own information, so it feels natural. Many businesses combine the two: menus for the simple paths, AI for everything else.

Steps to plan one that works

  1. List the top 20 questions your team answers. These become the bot's knowledge.
  2. Write the answers once, correctly, in one place: prices, policies, delivery rules.
  3. Decide the handover rule: when should it stop and call a person? Angry customers, payments and special requests are good triggers.
  4. Connect it to your tools, such as your order sheet or booking system, so it can act and not only reply.
  5. Test with real past conversations before going live, then review the chats weekly and fix gaps.

Mistakes to avoid

  • Letting the bot guess prices or policies it was never given.
  • No easy way to reach a human.
  • Launching to everyone at once instead of testing on a small group first.
