Only genuinely available slots are shown, so whatever they pick, they get. One reminder the day before and one before the start; customers can cancel to reschedule and the slot goes straight back into the pool. The whole flow runs inside the chat— no redirects, no switching interfaces.
Bookings get negotiated one LINE message at a time. Miss a reply while you're busy and the customer books elsewhere.
You're paying monthly for a booking system, but it can't handle your flow — you need birth details up front, different practitioners, a deposit — so you patch the gaps by hand.
Two customers land on the same slot and you have to call one of them to apologise. That can't happen twice.
We built and run a complete LINE booking system as a live demo. Not a video, not screenshots — add it as a friend right now and walk the whole flow.
Four practitioners, each with their own specialities and schedules. Customers pick a practitioner and a slot, and someone has to open the session when the time comes.
See for yourself Add on LINE @832hjmkt: one free reading → pick a practitioner → see only genuinely open slots → get a pre-session reminder → the practitioner opens the session on time. All without ever leaving LINE.
Rental enquiries were scattered across LINE and phone calls. Customers asked, then disappeared, with no record to follow up on.
Result Bookings push straight to the owner's phone, the admin panel shows orders and customer lists, and closing a job updates the status automatically.
Off-the-shelf LINE booking SaaS (HotCake, SimplyBook and similar) runs a few hundred to a couple of thousand NT dollars a month. If you're in the left-hand column, go use them — you don't need us.
Every item below works on the FATE demo — go verify it yourself.
Dates and times both use LINE's native pickers, and only genuinely open slots are listed. Whatever they pick, they get — no "sorry, that's already booked" after submitting.
The slot is locked at the database level first, and only the winner is written in. This is where booking systems most often break — not in the interface.
One the night before, one before the start. Customers cancel themselves to reschedule, and the slot returns to the pool automatically. No manual support required.
When customers skip the buttons and type "any openings Friday night?", the system still parses it into a booking intent. Available slots are still queried from the database by code — the AI won't invent a time that doesn't exist.
Booking lists, schedules (weekly templates that roll forward automatically) and full conversation logs. Day-to-day content is yours to edit — no need to come back to us.
When a customer asks for a human, the bot locks itself out and the message goes straight to your Telegram, where you reply directly. Hand it back to the bot when you're done.
Priced by number of services, staff and venues, and whether existing systems need connecting. Once confirmed, no additional hours are billed.
Booking data is shared across both, so customers get the same system whether they arrive via the website or LINE. Websites from NT$18,000, quoted on overall scope when built together.
ECPay or MyCard payment integration, so deposits are taken at the moment of booking and no-shows drop. Priced separately depending on the payment provider's plan.
Write bookings back into your current CRM, POS or membership database. Priced separately depending on whether that system has an API — we need to look at it before quoting.
Walk us through how you take bookings today. This step decides whether you should be using a monthly system at all — if you should, we'll say so rather than take the job.
We map every step and every branch (fully booked, cancellation, rescheduling, human handoff) into a diagram for you to approve. Skip the alignment here and there's guaranteed rework later.
You get a test LINE account first and walk through it as a customer a few times. We only switch to the live account once it genuinely flows.
Admin accounts, source code, database and documentation all handed over to you. Schedules and services are yours to edit from then on.
From NT$45,000, live in 3–4 weeks, including LINE Official Account setup, booking flow, reminder push and admin panel.
The final quote depends on the number of services, staff and venues, and whether existing systems need connecting. Once confirmed, the quote is the total — no hourly billing.
A monthly systemfits your flow into its framework; a custom buildshapes the system around your flow。
If your flow is standard (pick a service, pick a time, confirm), a monthly system at a few hundred to a couple of thousand NT dollars is far better value — and we'll tell you to go use one. Custom pays off when your flow isn't standard, you need to connect existing systems, customer data has to stay in your hands, or five years of subscription fees already exceed a one-off build.
LINE only is fine. The whole flow completes inside the chat — no jumping out to fill in a form.
If you want a website as well, both share the same booking data. Websites from NT$18,000, quoted on overall scope when built together.
No. Slots useatomic locking: the database locks the slot first and only the winner's booking is written in. The other customer is told on the spot that the slot has just been taken and picks again.
This is the most common failure in booking systems. You can verify the behaviour yourself on the FATE demo.
That's paiddirectly to LINE and is separate from development. Official Accounts have a free plan; you only need to upgrade if outbound push exceeds the free allowance.
Replies to customer messages use the Reply API and don't count toward the push allowance — only reminder pushes do. The account is registered in your name; we don't hold it for you.
3–4 weeks. What you need to prepare: your services and how long each takes, opening hours and closing days, whether you want deposits, and how far in advance reminders should go out.
Missing materials are the most common cause of delay, not development speed. We'll give you a checklist at the first meeting.
Adjustments within 30 days of launch aren't billed separately. After that, day-to-day content like services, slots and schedules isyours to edit in the admin panel— no need to come to us.
Changing the flow itself (adding a payment step, for example) counts as new development work.
You do. Both the database and source code are handed over, so you can export at any time or switch maintainers. We don't hold your customer data for you.
Same question, different answers — it comes down to how standard your flow is and whether the data has to stay with you.
Breaking down the quote: which parts you have to pay for, and which can wait.
Same name, three completely different sets of requirements.
