LINE OA
LINE OA (LINE Official Account) is a business account on LINE. A company uses it to chat with customers, send messages and offer services inside LINE. With custom development, it connects to your own systems and data.
What we build on LINE OA
Member and loyalty systems
Link each LINE account to your member or staff record, then run points, coupons, rewards and campaigns inside LINE. Pruksa's Well Living Club is one we built.
AI agent in LINE OA
An AI agent that answers from your company's data and does real tasks: it finds, checks and books, with the customer's tap to confirm. Complex cases go to your staff at once.
LIFF apps
Web apps that open inside LINE for member cards, bookings and payments by credit card or transfer slip. Customers stay in the chat they already use.
Verified member groups
Members confirm who they are by OTP, or against your SAP, HR portal or member list, before the menu and AI agent open up. Access ends the moment someone leaves.
1:1 notifications
Personal messages for each customer, sent from your own systems, such as reminders and status updates.
Links to your systems
Middleware that connects LINE OA to CRM, ERP, payment gateways, core banking, insurance systems and HIS through APIs and webhooks.

How we build your LINE OA
Systems we connect LINE OA to
CRM | ERP | SAP | HR portal | Core Banking | Insurance core systems | HIS | Payment Gateway | Credit card payment | Transfer slip check
Map the goal and the flow
We start from the business goal, then design the chat flow and the system architecture.
Build and connect
We build the AI agent, LIFF apps and middleware that link LINE OA to your systems.
Test, then go live
We test security and performance before Go-live.
Data stays on your side
Customer data is stored in your organisation's systems, with role-based access and encryption in transit and at rest, in line with PDPA.
Look after it under an SLA
After Go-live we fix, improve and support the system under an agreed SLA, through MA and CR.
How pricing works
Each LINE OA we build fits one organisation, so the price depends on the scope and on how many systems we connect. After a call, we send a free assessment and quotation. A first version takes a few weeks, and larger integrations go live in phases.
Fixed scope
One price for an agreed scope, set after Discovery. It suits a first version with clear features.
Monthly team
A dedicated team at a monthly fee, with support included. It suits a LINE OA that adds campaigns and features every month.
MA and CR after Go-live
After Go-live, MA keeps the system healthy under an agreed SLA and covers fixes to what we delivered. New features are change requests (CR), quoted one by one.
Technology we use
LIFF | Next.js | React | Node.js | NestJS | PostgreSQL | Large language models (LLM) | AWS | Google Cloud | Microsoft Azure
LINE OA questions
What can a LINE OA do for an organisation?
A LINE OA can chat with customers, send 1:1 messages, run member and loyalty programmes and open LIFF apps for bookings or payments. With middleware, it works with your CRM, ERP or core systems.
Does LINE OA cost money?
Opening a LINE OA account is free. LINE charges for extras such as a Premium ID or more messages per month. Our fee covers the system we build and is quoted separately.
Can it connect to our member system or CRM?
Yes. We build middleware that links LINE OA to CRM, ERP, core banking, HIS and other internal systems through APIs and webhooks.
Can we add an AI agent to our LINE OA?
Yes. Our AI agent in LINE OA answers from your own data and knowledge base. It does tasks such as finding, checking and booking, with the customer's tap to confirm. It reads slips and documents, and passes complex cases to your staff.
How do you keep customer data safe under PDPA?
Customer data is stored in your organisation's systems. We design for PDPA, with consent records, data-subject rights, role-based access and encryption.
How long does a LINE OA project take?
A first version takes a few weeks. Complex integrations are planned in phases with your team.
