In Bangladesh most online orders start as a message: “dam koto?”, “size ache?”, a screenshot of a product, or a comment under a post. A chatbot for an online shop has one job — answer those questions correctly, fast, in the buyer's language, and turn the conversation into an order. This guide lists what that takes, the three kinds of chatbot you can choose from, and what each costs.
1What a shop chatbot should do
- Understand Bangla, Banglish and English, including spelling like “koto” and “ase”, and voice notes.
- Quote price, sizes and stock from your own catalog, never a guess, and say so when something is out of stock.
- Recognise a product from a screenshot or photo, because many buyers send a picture instead of a name.
- Take the cash-on-delivery order: name, phone, address, the delivery charge for that area, and a summary the buyer confirms.
- Work where buyers are: Messenger, comments under your posts, Instagram, WhatsApp and your website.
- Hand over to your team when a buyer complains or asks something it shouldn't answer, without the buyer starting again.
- Stay in step with your store, so a price change or a sold-out size on your website is what the chatbot says too.
2The three kinds of chatbot
| Kind | How it answers | Good for |
|---|---|---|
| Meta's free auto reply | One fixed message to everyone | A few messages a day |
| Keyword or flow bot | Fixed answers when a message contains a chosen word | Menus and campaigns you design |
| AI sales agent | Reads the question and your catalog, answers each buyer, takes the order | Shops with many products and daily questions |
Setting up Meta's free reply, step by step, is in our Facebook Page auto reply guide; ready-to-paste texts are in the message samples.
3What it costs compared with a moderator
A page moderator in Bangladesh costs about ৳12,000–18,000 a month and works one shift. OmniConva's free plan includes 100 AI credits a month; paid plans are ৳999, ৳2,499 and ৳4,999 a month, from 12 paisa per message, and answer around the clock. Put your own numbers into the moderator cost calculator to compare.
4Questions to ask before you choose
- Does it connect through Facebook login and Meta's official API, without asking for your password?
- Can I try it free on my own Page before paying?
- Can I pay in taka, by bKash or Nagad?
- What happens when the monthly replies run out — does it stop and pass chats to my team, or charge more?
- Can several people on my team use the same inbox?
- Are customer chats used to train AI models?
How the main tools answer these is in our comparisons and the ManyChat alternatives list.
5Setting up OmniConva on your shop
- Sign up with your phone number and create your store.
- Connect your Facebook Page, and Instagram or WhatsApp if you sell there, from Settings › Connection.
- Add your products: connect WooCommerce, Shopify, BitCommerz or your own website, or upload a CSV.
- Set your delivery charges, and write your shop's policies (exchange, delivery time) in the knowledge base, so the AI answers those too.
- Turn on AI replies and message your Page from another account to test it.
Questions people ask
Which chatbot is best for an online shop in Bangladesh?
It depends on how many messages you get. For a few a day, Meta's free auto reply is enough. For a shop with many products and daily questions, pick an AI agent that understands Bangla, answers from your catalog and takes the cash-on-delivery order.
Is there a free chatbot for a Facebook shop?
Yes. Meta's auto reply in Business Suite is free, and OmniConva has a free plan with 100 AI credits a month and 10 products, with no time limit.
Will a chatbot give wrong prices?
A well-built one answers only from your own product data. OmniConva quotes prices and stock from your catalog or connected store and passes the chat to your team when it isn't sure.
