Can You Manage Clients on LINE? How Sales Reps Use LINE With Customers, and Where to Draw the Line

LINE is good for chatting with clients and bad for managing them. For readers outside Asia: LINE is the messaging app most people in Taiwan use every day, and it is the channel Taiwanese sales reps rely on most to reach clients. Quotes go out over LINE, sample photos go out over LINE, meetings get scheduled on LINE. After a while it feels natural to think, "All my clients are in my LINE. Why would I need another system?" This article explains where relying on LINE alone breaks down, and how to split the work between LINE and customer management.

Where Managing Clients Only on LINE Goes Wrong

The biggest problem is that the data doesn't belong to the company.

When a rep adds clients as friends on a personal account, the chat history is stored in that rep's account and phone. On the day the rep resigns, those conversations walk out the door too. Whoever takes over gets a client list but has no idea what was quoted last time, which delivery date was promised, or what the client was unhappy about. They have to ask everything again from scratch.

The second problem is that chats disappear. Switch phones without backing up your chats, and the old conversations are gone for good. Files and photos in group chats can also expire and stop opening if they sit too long. Reps themselves often can't remember which quote was the final version.

The third problem is that you can't find things. LINE search only matches keywords. It can't answer the questions a rep actually needs answered:

• Which clients are due for a follow-up this month?
• Of the deals in progress, which ones have reached the quoting stage?
• Which of our clients are in the food industry?
• Who haven't we visited in more than three months?

Answering those takes fixed fields for every client: industry, stage, last contact date, next follow-up date. A chat history is one long stream of text with no fields at all.

B2B reps also deal with group chats a lot. One project gets one LINE group, with purchasing, engineering, and management on the client side and sales and engineers on ours, and dozens of messages a day. Three months later, finding the spec you agreed on means scrolling up and up. Groups carry another risk: if the rep is the only person from your company in the group, the company loses all visibility into that project the moment they leave. When you open a group, put at least two colleagues in it, and name the group after the client company and the project so it's easy to search later.

The fourth problem is that managers can't see anything. A sales manager who wants to know what deals the team is working on can't go through everyone's LINE. So the weekly meeting turns into one verbal report after another, and nothing gets recorded afterwards.

Personal Accounts vs. Official Accounts

For company-to-client communication, use a LINE Official Account (LINE's business account type) rather than reps' personal accounts.

Comparison	Personal account	Official Account
Who owns the account	The individual rep	The company
When the rep leaves	Conversations leave with them	Conversations stay with the company
Multiple managers	Not possible	Multiple admins can be assigned
Client categorization	Memory only	Chats can be tagged
Broadcast messages	Not suitable	Possible, with message limits

An Official Account belongs to the company, and several colleagues can manage it together. When the rep on an account changes, you just transfer access to the new person, and all the old conversations are still there. Chats can be tagged, for example "Quoting" or "Food industry", which beats having everything mixed together.

Official Accounts have a cost too. Clients have to add a separate account as a friend, and some long-time clients feel closer chatting with the rep personally. Broadcast messages come with a monthly free quota, and anything beyond it is paid. For specifics, go by the plans LINE currently publishes.

In practice, many companies use both. New clients always start on the Official Account. Long-standing clients who have used a rep's personal account for years aren't forced to switch, but important exchanges still get recorded in the company's system.

Dividing the Work Between LINE and a CRM

Treat LINE as the phone and the CRM as the client file.

When you hang up a call, you don't expect the call itself to become a record. You write in the client file: "Confirmed delivery date today; need to send the quote by next Wednesday." LINE works the same way. After the conversation, record the conclusion in the CRM and leave the conversation itself in LINE.

You're not logging the full chat. You're logging four things:

• What was concluded this time
• What the client cares about or the conditions they raised
• What needs to happen next
• When to follow up

One or two minutes each time is enough. Once it's in the CRM, the system can remind you when the follow-up date arrives, and managers can see each deal's progress directly without going around the table at the weekly meeting. For setting up follow-up reminders, see CRM Automation for Beginners.

Store the client's LINE ID or the Official Account chat link as a contact field in the client record, just like a phone number or email. That way, even when the rep changes, the new person knows which channel to use.

Many people searching for "LINE CRM" are looking for a customer management tool that connects directly to LINE. These tools use the interface LINE Official Accounts provide to pull chat history or friend lists into the system. If that's what you need, check two things before buying: whether it connects to Official Accounts or personal accounts (personal accounts usually can't be connected), and whether chat history actually gets saved into the client record.

What You Can Start Doing Tomorrow

You don't have to move every client at once. Start by getting new clients right.

Step one: have the company open a LINE Official Account and add new clients there. At trade shows or client visits you can show the Official Account's QR code directly, and you can print it on business cards. For exchanging contact details on LINE, see How to Make a LINE Digital Business Card.

Step two: every time a conversation with a client reaches a conclusion, record it in the CRM that same day and fill in the next follow-up date. At first it feels like an extra chore. Two or three weeks in, you'll notice that no longer digging through LINE for "where did we leave off?" saves more time than it costs.

Step three: when a rep resigns or moves to another role, add an item to the handover checklist covering the transfer of Official Account admin access and the latest status of every client in the CRM.
