 This is the story of how it went together — the architecture, the LLM wiring,
 and the bugs that ate an afternoon each.
 
+## Why a business needs a bot like this
+
+Before the architecture, the *why*. A support bot isn't a gimmick — it changes
+the economics of a small business:
+
+- **Saves money on staff.** Every routine question a bot answers is one your
+  team doesn't have to. Digi Kedai gets the equivalent of a round-the-clock
+  support agent for a fraction of the cost of hiring one.
+- **Answers instantly, 24/7.** Customers ask at midnight and on weekends. A bot
+  replies in seconds, in their language — no queues, no "we'll get back to you".
+- **Converts browsers into buyers.** The bot doesn't just answer — it *upsells*.
+  A "does this have a free trial?" question turns into a claimed trial account
+  in a couple of taps, with no human in the loop.
+- **Never forgets a customer.** Long-term memory means repeat customers are
+  greeted like regulars, not strangers.
+- **Scales with your catalogue.** Add a product and the bot already knows it —
+  no retraining, no new FAQ pages.
+
+For a one-person business like Digi Kedai, that's the difference between losing
+sales at 2 a.m. and closing them.

 这篇讲的是它是怎么搭起来的——架构、LLM 接线，以及那些各自吃掉我一整个下午的 bug。
 
+## 为什么企业需要一个这样的机器人
+
+讲架构之前，先说*为什么*。客服机器人不是噱头——它改变了小生意的经济学：
+
+- **省钱省人力。** 机器人每回答一个常规问题，你的团队就少答一个。Digi Kedai 用雇一个客服几分之一的成本，就得到了一个全天候的客服专员。
+- **全天候即时响应。** 顾客会在半夜和周末提问。机器人几秒钟内用他们的语言回复——没有排队，没有「我们稍后回复」。
+- **把浏览者变成买家。** 机器人不只是回答——它还会*向上销售*。一句「有免费试用吗？」几下点击就变成一个已领取的试用账号，全程无需人工。
+- **永远记得顾客。** 长期记忆让回头客被当作熟客问候，而不是陌生人。
+- **随商品目录扩展。** 加一个商品，机器人就已经认识它了——无需重新训练，无需新的 FAQ 页面。
+
+对 Digi Kedai 这样一个人的生意来说，这就是在凌晨两点丢单和成交之间的差别。

 如果你也在打造一个 LLM 驱动的 Telegram 机器人，教训其实很朴素：模型是最容易的部分。webhook 生命周期、payload 契约、以及开通流程的幂等性才是真正会出问题的地方——先设计好这些。
