LINE Bot Development in Osaka — Official Account Automation & LIFF Builds
A LINE Official Account lets customers make bookings and send inquiries around the clock, inside an app they already use every day. Sugureru handles everything end to end with the Messaging API — booking management, automated inquiry responses, and LIFF (mini apps inside LINE).
LINE Bot development sized to a small-business budget — from ¥300,000 (excl. tax). Rich menus, Flex Messages, scenario branching, CRM integration — we build only the features your business actually needs, no more.
Do any of these challenges sound familiar?
- ▸"We set up a LINE Official Account, but sending messages by hand is wearing us out."
- ▸"We want to take bookings and inquiries via LINE, but staffing it 24 hours a day is physically impossible."
- ▸"We hear terms like Messaging API, LIFF, and WebHook, but have no idea what they mean."
- ▸"Quotes from LINE Bot development vendors run over ¥1,000,000–2,000,000 and just don't fit our budget."
- ▸"We want to build an 'AI customer-service LINE Bot' combined with generative AI."
Three reasons clients choose Sugureru
1. A "start minimal, then expand" approach from ¥300,000
Start with a minimal setup of "automated responses + a rich menu" (¥300,000, 2–3 weeks, excl. tax). As you see results, expand step by step into CRM integration, AI chat, and LIFF apps. Rather than committing a large budget up front, you start small and grow step by step.
2. Designed around how your industry works — restaurants, beauty, professional services, e-commerce
Restaurant bookings and reminders, salon repeat-visit prompts, inquiry routing for professional firms, delivery-status notifications for e-commerce — what a LINE Bot needs to do differs by industry. We learn your industry and workflow first, then propose the features you need, in order of priority.
3. "AI customer service" is possible too, via generative AI integration
Beyond simple automated responses, we can build AI customer-service bots that combine a generative AI API to answer customers' natural-language questions intelligently. You can run a hybrid model: FAQ-based first responses, with handoff to a human operator only when needed.
What a LINE Bot can do
Automated bookings and cancellations
For restaurants, salons, clinics, and more — everything from checking open slots to completing a booking, sending automatic reminders, and accepting cancellations is handled entirely within LINE.
24-hour automated FAQ responses
Instant automatic answers to common questions (business hours, parking, menu, prices, and so on). The bot gives the first response to routine inquiries, escalating only the difficult cases to an operator.
Rich menu design
We optimize the persistent menu at the bottom of the chat screen. Frequently used features are placed a single tap away. We can also switch the menu by day of the week or time of day.
LIFF mini app development
Using the LINE Front-end Framework, we build stamp cards, point programs, membership cards, order forms, surveys, and more as web apps that run entirely inside LINE. No download required, so adoption rates are high.

Frequently asked questions
I haven't even created a LINE Official Account yet. Can you build just the bot?
We support you from the very start, including opening the Official Account. Talk to us about obtaining LINE's verification, enabling the Messaging API, and choosing between the Free, Light, and Standard plans.
Are there separate message delivery costs?
Yes. The monthly message delivery fees for your LINE Official Account (paid to LINE) are charged separately. For example, the Light plan is ¥5,000/month (tax excluded) for up to 5,000 messages; we'll recommend the right option for your delivery volume.
Can you combine it with AI such as generative AI?
Yes. We can build a LINE Bot that responds in natural language by integrating a generative AI API. It's ideal for automated FAQ responses and handling first-line customer support.
Can you integrate with our existing booking system or e-commerce site?
Yes. In most cases we can integrate with services that offer a public API, including major services such as STORES Reservations, RESERVA, Shopify, Square POS, and kintone. We confirm whether, and how far, integration is possible during the hearing.
Who handles operation and message updates after launch?
You can update rich menus and template messages yourself from the admin panel. Scenario changes and additional features can be handled either through a monthly maintenance plan (¥30,000–100,000/month) or on a per-request basis.
Can you measure performance?
We can build a dashboard that visualizes block rate, message open rate, rich menu clicks, and the completion rate of each scenario. We also support integration with BI tools such as Looker Studio.
