What an AI sales agent for Facebook, Instagram and WhatsApp includes in Bangladesh, where its answers come from, what it costs to run, and what we learned building BotBhai, a live Bangla-first sales agent.

§ 01Building an AI Sales Agent for Facebook Commerce in Bangladesh: Features and Lessons from BotBhai

Picture a fashion page in Mirpur at two in the morning. A boosted post went out at nine. The owner answered messages until midnight, then fell asleep with the phone on the pillow. By morning there are dozens of unread chats: "দাম কত?", “dam koto?”, a screenshot with no text, a voice note with an address in it. Some of those customers have already bought the same dress from another page.

That gap is the business opportunity. In Bangladesh, much of online selling happens inside Facebook, Instagram and WhatsApp conversations rather than on checkout pages. The customer asks, someone answers, and the order is pieced together from the chat. An AI sales agent does the answering — and the piecing together — around the clock, in the language the customer actually typed.

Shop owners, social-commerce teams and growing brands all want something slightly different from one. The owner wants every message answered. The team wants orders that arrive complete. The brand wants replies that sound like the brand. This guide covers what an AI sales agent includes, what makes one harder to build than a simple auto-reply, where its answers come from, what it costs to run, and what we learned building BotBhai.

§ 02The short answer: three levels of automation

We group AI sales agents into three levels: Reply, Sell and Operate. Each level builds on the one before it.

LevelBest forWhat you get (short)
ReplyPages drowning in “price?” messages and commentsInstant replies to messages and comments from your product information, on one Facebook page
SellGrowing shops that take orders in the inboxEverything in Reply, plus image and voice understanding, order capture, order management and a dashboard — on Facebook, Instagram and your website
OperateBrands selling on every channel, or across several pagesEverything in Sell, plus WhatsApp and higher message volume — and, on a custom plan, multiple pages and custom integrations

On BotBhai these levels map to the Choto Bhai, Mejho Bhai and Boro Bhai plans, with Custom Bhai for multi-page setups.

§ 03See it live: what BotBhai includes

BotBhai is an AI sales agent we built and run for Bangladeshi social-commerce businesses. It is live at botbhai.net. Here is what it does, feature by feature, and why each one matters to a seller.

FeatureWhat it does for the seller
Instant message replyAnswers price, size and stock questions the moment they arrive — the first reply goes out in about half a second.
Bangla and BanglishReads "দাম কত?", “dam koto?” and “price?” as the same question, and replies in the customer’s language.
Your brand’s voiceLearns the tone you want — playful, polite or formal — so replies sound like your page, not a robot.
Comment replyAnswers “Price?” under your posts and continues the conversation in the inbox, so no lead from a boosted post is missed.
Image recognitionIdentifies the product from a photo or screenshot the customer sends, and answers with the right details.
Voice message recognitionUnderstands voice notes — including sizes and addresses spoken quickly.
Order captureBuilds the order as the chat happens: product, variant, quantity, customer, address, total and payment. A typical message-to-order flow takes about 50 seconds.
Order managementTracks, updates and manages orders in one place instead of in screenshots and notebooks.
Dashboard analyticsShows orders, customers, payments and sales at a glance.
Human handoverWhen it does not know — a wholesale discount, an unusual request — it says it will check with the owner and sends the chat to you.
Take over or stopStep into any chat and reply yourself, or stop the agent with one click from the sidebar.
Selling rulesDelivery charges and payment rules (cash on delivery or bKash, for example) follow your shop’s settings.
ChannelsFacebook, Instagram, WhatsApp and your website, depending on the plan.
Official Meta APIConnects with “Login with Facebook” and the permissions you grant — no password, and access you can remove at any time.

Feature names follow the live product. Some features depend on the plan — see the next section.

§ 04What each level includes

These lists show what BotBhai includes at each level, with the plan and monthly price listed on botbhai.net at the time of writing.

  • Reply — Choto Bhai · ৳3,000/month
  • Automatic message replies
  • Comment replies
  • 5,000 messages a month
  • One Facebook page
  • Your brand in the replies — no BotBhai labelling
  • Extra messages when you need them

This is enough to stop losing first replies — the most common leak — without changing how you take orders.

§ 05Sell — Mejho Bhai · ৳5,000/month

Everything in Reply, plus:

  • 10,000 messages a month
  • Image recognition
  • Voice message recognition
  • Order management
  • Dashboard analytics
  • Facebook, Instagram and your website

Image and voice understanding are where an agent stops being an auto-reply and starts taking orders. Most shops that sell in the inbox will want at least this level.

§ 06Operate — Boro Bhai · ৳8,000/month · Custom Bhai

Everything in Sell, plus:

  • 20,000 messages a month
  • WhatsApp, alongside Facebook, Instagram and your website
  • Multiple pages (Custom Bhai)
  • Custom integrations (Custom Bhai)
  • Enterprise SLA (Custom Bhai)

This is for brands where conversations arrive on every channel at once, or where several pages share one team.

Before you pick a plan: Every plan starts with a three-day free trial and no card. Setup help and support are included, and yearly billing adds a month free. Prices are as listed on botbhai.net in November 2026 — check the site for current pricing.

§ 07What makes an AI sales agent harder to build

Two agents with the same chat window can differ enormously in effort. The difference sits in a handful of capabilities.

FeatureWhy it is harder than it looksEffort
Bangla and Banglish understandingThere is no fixed spelling. The same word is typed five ways, and one message can mix Bangla script, Latin script and English.High
Image recognitionScreenshots arrive cropped, compressed and covered in stickers or price tags — and must be matched to your catalog, not to the internet.High
Voice messagesBackground noise, regional accents and addresses spoken fast, often in a mix of languages.High
Order capture across messagesDetails arrive out of order and spread across many messages. The agent has to assemble one clean, confirmed order.High
Not inventing answersLanguage models are fluent by default. Keeping every price and promise tied to your data — and stopping when the data runs out — takes deliberate design.High
Comment-to-inbox flowA public reply and a private follow-up, timed well and within Meta’s platform rules.Medium
Human handoverA person has to be able to step in cleanly, without the agent and the person talking over each other.Medium
Delivery and payment rulesCharges differ by area, some shops want an advance, and payment confirmations need checking before an order moves.Medium

§ 08Where the answers come from

An AI sales agent should not be clever about facts. Every price, size and delivery charge it quotes has to come from somewhere you control. In BotBhai, answers come from three places:

Your product list — names, photos, prices, variants and stock, edited in the dashboard.

Your shop rules — delivery charges, payment rules and the tone you want, set in the agent’s configuration.

The conversation itself — what this customer has already said, so they are never asked twice.

The model’s job is to understand the customer and match the question to your data. It is not allowed to invent a price. When it does not know, it says so politely and sends the chat to you.

An agent that guesses is worse than an agent that waits.

The page itself connects through Meta’s official API, with permissions you grant. There is no password to hand over, and you can remove access from your page settings at any time.

§ 09Running costs people forget

The subscription is the obvious cost. These are the others worth budgeting for.

CostWhat it coversPaid to
SubscriptionThe agent, the dashboard and the monthly message allowanceBotBhai
Extra messagesVolume above your plan during campaigns and Eid salesBotBhai
Catalog upkeepUpdating prices, stock and new collections so answers stay rightYour team’s time
Handover timeComplaints, wholesale enquiries and special requestsYour team’s time
Ad spendBoosted posts and ads that bring the messages inMeta
Delivery and payment feesCourier charges, and mobile wallet or bank fees on each orderCourier and payment providers

For comparison, BotBhai’s own estimate puts one human moderator at ৳10,000–12,000 a month for a single shift, against ৳3,000 for its entry plan running around the clock. The real saving depends on how many shifts you cover today and how much handover your products need.

§ 10The agent has to match the operation

An agent that takes orders faster than the warehouse can pack them only moves the queue. Before switching one on, decide who does what after the chat ends.

  • Who confirms advance payments, and how quickly?
  • Who picks up a chat the agent hands over — and during which hours?
  • What delivery time is the agent allowed to promise?
  • What happens to an order the customer cancels after confirming?

BotBhai keeps the owner in control for exactly this reason. You can step into any conversation and reply yourself, stop the agent with one click, and change the selling rules or product information from the dashboard.

§ 11Keyword auto-reply or AI sales agent?

Keyword auto-reply toolAI sales agent
Setup speedFastFast — about two minutes to connect a page
Bangla and BanglishFixed keywords onlyFree-form messages in either
Photos and voice notesIgnoredUnderstood (Sell and Operate)

When it doesn’t knowSends the keyword reply anywayHands the chat to a person
Page accessSome tools ask for your passwordOfficial Meta API, no password
Monthly costLowerHigher than a keyword bot, lower than a moderator

A keyword tool is fine if every customer asks the same question the same way. In Bangladesh they rarely do.

§ 12How OddBirds built BotBhai

We built BotBhai the way we build client products: understand the work first, define the scope, design the experience, then build and review as we go. A few decisions shaped almost everything else.

Answer only from the seller’s data. The agent quotes what the shop has entered — nothing more. That rule limits what it can say, and that is the point.

Hand over instead of guessing. When a question falls outside the data, the chat goes to a person with a polite holding reply, not a confident wrong answer.

Build the order during the chat. Product, variant, quantity, customer, address, total and payment fill in as the conversation happens, so nothing is re-typed afterwards.

Keep the owner in control. Take over any chat, stop the agent with one click, and change the rules or catalog without asking us.

Use the official Meta platform. Connecting through Meta’s API means no shared passwords, and access the owner can revoke at any time.

If you are planning your own AI product — a sales agent or something odder — the same order of work applies. Talk to us about it.

  • Frequently asked questions
  • What is an AI sales agent?

Software that answers customer messages and comments on channels like Facebook, Instagram and WhatsApp, understands what each customer wants, and takes the order — using your product data and shop rules.

§ 13Can BotBhai reply in Bangla?

Yes. It understands and replies in Bangla and Banglish, and it can match the tone you choose for your brand.

§ 14Will my Facebook page get banned?

BotBhai connects through Meta’s official API and follows Facebook’s policies. It never asks for your password, and you can remove its access from your page settings at any time.

§ 15How long does setup take?

Connecting a page takes about two minutes: log in with Facebook and choose the page. The BotBhai team helps with setup at no extra cost.

§ 16Does the bot give wrong answers?

It does not make up prices or information. It answers from what you give it, and when it doesn’t know, it notifies you and hands the chat over.

§ 17Can I connect more than one page?

Yes, on the Custom Bhai plan.

§ 18Is the free trial really free?

Yes. Three days, no card and no hidden charges.

§ 19How do I pay for BotBhai?

bKash, Nagad, Rocket and bank transfer are all accepted.
