AI sales agent

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.

Building 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.

The 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.

Level	Best for	What you get (short)
Reply	Pages drowning in “price?” messages and comments	Instant replies to messages and comments from your product information, in one Facebook page
Sell	Growing shops that take orders in the inbox	Everything in Reply, plus image and voice understanding, order capture, order management and a dashboard — on Facebook, Instagram and your website
Operate	Brands selling on every channel, or across several pages	Everything 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, Mejo Bhai and Boro Bhai plans, with Custom Bhai for multi-page setups.

See it live: what BotBhai includes

BotBhai is an AI sales agent we built and run for Bangladesh's 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.

Feature	What it does for the seller
Instant message reply	Answers price, size and stock questions the moment they arrive — the first reply goes out in about half a second.
Bangla and Banglish	Reads “দাম কত?”, “dam koto?” and “price?” as the same question, and replies in the customer's language.
Your brand's voice	Learns the tone you want — playful, polite or formal — so replies sound like your page, not a robot.
Comment reply	Answers “Price?” under your posts and continues the conversation in the inbox, so no lead from a boosted post is missed.
Image recognition	Identifies the product from a photo or screenshot the customer sends, and answers with the right details.
Voice message recognition	Understands voice notes — including sizes and addresses spoken quickly.
Order capture	Builds the order as the chat happens: product, variant, quantity, customer, address, total and payment.
Order management	Tracks, updates and manages orders in one place instead of in screenshots and notebooks.
Dashboard analytics	Shows orders, customers, payments and sales at a glance.
Human handover	When 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 stop	Step into any chat and reply yourself, or stop the agent with one click from the sidebar.
Selling rules	Delivers changes and payment rules (cash on delivery or bKash, for example) follow your shop's settings.
Channels	Facebook, Instagram, WhatsApp and your website, depending on the plan.
Official Meta API	Connects 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.
