LINE Official Account on autopilot:
a rich menu that routes, replies that answer
LINE is where a large share of customers in Thailand and Japan actually message a business, and a LINE Official Account with a flat rich menu and no real auto-replies wastes that channel. We build a rich menu that routes customers to the right flow and an agent that answers real questions, the setup we run live for a sports nutrition brand on LINE today.
The process today
A LINE Official Account with only the default flat menu and no real auto-reply logic puts the full weight of every incoming message on a manager, who has to type the same answer to the same FAQ questions dozens of times a day. Outside working hours the account goes quiet, and a customer in a time zone that is awake while the team sleeps gets no answer until the next morning, if they bother to wait.
The second cost is routing: a customer who wants an order status, a customer who wants to buy, and a customer with a complaint all land in the same undifferentiated inbox, and sorting them by hand is slow and inconsistent depending on who reads the message first.
The third is the rich menu itself sitting unused as a static image instead of an actual navigation tool, because wiring it to real flows takes developer time that a non-technical team usually does not have on hand.
What the agent does
The agent answers real questions, pricing, product details, order status, FAQ, drawing on your actual product and policy information rather than a generic script, and does it within the first minute regardless of time of day. The rich menu is wired to real flows: browse, track an order, talk to a person, each one landing the customer in the right automated or human path instead of a dead end.
For a customer who drops off mid-conversation, a well-timed follow-up brings them back once before the thread is marked cold. Anything that reads as a complaint, a negotiation, or a question outside the script hands off to a manager with the full conversation attached, the same multi-channel approach we run live on LINE for a real sports nutrition brand today, with per-channel send limits to stay inside LINE’s own rules.
Typical setup: LINE Messaging API, your product and FAQ data, and your existing CRM or order system for status lookups.
Rollout follows the same sequence across every automation we build: map the real process together with the people doing the work today, including the exceptions and the real volume, not just the clean-path version; build and test against a sample of your real data rather than a demo dataset; run a dry run against live activity before anything is allowed to act on its own; then hand over the logs, the kill switch and a short written guide so your team can run it without us in the room. The 30-day tuning window that follows launch is treated as real work, not a formality: thresholds, wording and edge cases get adjusted against what the first weeks of real usage actually show, not against what looked right before launch.
What stays with humans
Closing a sale that needs negotiation, resolving a genuine complaint, and any policy exception stay with a person. The agent answers what the script and your data actually support; it does not invent product claims, and anything ambiguous is routed to a manager with context attached rather than guessed at.
Guards
Every conversation is logged, and send frequency per customer and per broadcast is capped inside LINE’s account limits to avoid a flag or a temporary block. The agent runs in a monitored mode against real incoming messages before full auto-reply goes live, and a kill switch turns off automated replies in one message if something looks wrong.

FAQ
How much does LINE OA automation cost?
From $700 for a rich menu plus auto-replies for your core FAQ and order questions, live in 4 to 8 days. Running LINE alongside other channels on one agent sits closer to our multi-channel package, which we have live in production.
Does this replace our LINE OA managers?
No, it answers the repeatable questions fast so managers spend their time on the conversations that actually need a person: negotiations, complaints, anything outside the script.
Can the rich menu change based on what the customer is doing?
Yes, the menu can branch by customer state, a new lead sees a different menu than a returning customer checking an order, instead of one static menu for everyone.
How does it avoid getting the account limited?
Send volume and broadcast frequency are kept inside LINE's published limits for your account tier, with automatic slowdown if anything looks off, the same anti-ban discipline we run on our own live LINE channel.
Is our customer data in LINE kept private?
Conversation data stays inside your LINE OA and your own systems; we do not export it anywhere outside what you authorise, and every automated reply is logged for review.
