Note: This article covers LINE, a messaging platform overwhelmingly popular in Japan but with limited use elsewhere, and related integrations. The information below will not be directly relevant if your customer base does not use LINE.
"RuffRuff 予約販売" helps reduce the lost sales opportunities that arise when items are out of stock, ahead of a new product launch, or awaiting restock.
You can implement pre-orders on your own Shopify store with remarkable ease, registering unlimited pre-order products and accepting unlimited pre-orders. It can also prevent customers from ordering pre-order and regular items together in the same order, and can send back-in-stock notifications when the restock date is unknown.
It also has many unique features not found in other pre-order apps, such as a "deferred payment" function that lets you collect payment before the product ships.
Many Shopify merchants are considering using LINE to strengthen customer communication and boost sales.
In this article, we'll give a comprehensive overview — from the basics of LINE Official Accounts, to real-world use cases, to apps that help you integrate LINE with Shopify.
What Is a LINE Official Account?
A LINE Official Account is a service that lets businesses and stores create an account on LINE and send information directly to users who add them as a friend.
Currently, over 300,000 (*1) businesses and stores use LINE Official Accounts.
On Shopify stores, they're commonly used for handling customer inquiries and sending out coupons and new product announcements.

Types of LINE Official Accounts

There are three types of LINE business accounts available.
- Premium Account
- Verified Account
- Unverified Account
Here's a closer look at each.
Premium Account
A Premium Account carries a green account badge.
Passing LINE Corporation's review process qualifies an account for Premium status, which also makes it more discoverable in in-app search results and expands access to certain features and payment methods.
Verified Account
A Verified Account carries a blue account badge.
As with Premium Accounts, passing LINE Corporation's review process qualifies an account as Verified, which also makes it more discoverable in in-app search results and expands access to certain features and payment methods.
Unverified Account
An Unverified Account carries a gray account badge.
Anyone can obtain this type of account. Its core features are the same as a Verified Account, and it can still be upgraded to a paid plan or purchase a premium ID.
Benefits of Using LINE
The benefits of using LINE include the following.
- Reach a broad range of age groups
- Send many different types of messages
- Collect many different types of data
- Streamline customer support
- Enable 1-on-1 communication
- Broadcast announcements and coupons all at once
Let's look at each in detail.
Reach a broad range of age groups

LINE has 93 million monthly users (as of the end of March 2022), spanning a broad range of age groups from teens through people in their 60s and older.
Instagram skews toward female users, TikTok toward younger users, and Facebook toward middle-aged and older users. If you want to reach a specific audience, other social channels may be a better fit, but since over 70% of people in Japan use LINE, it lets you reach a broad audience without narrowing your target.
Send many different types of messages
The messaging feature of a LINE Official Account lets you send many different types of messages, including video messages, voice messages, and card-format messages.
By connecting your Shopify store with LINE, you can do things like distribute coupons only to users who purchased a specific product, send after-sales follow-up messages such as usage instructions, send catalogs of new products, or use surveys to understand customer needs — it's useful across a wide range of scenarios.
Collect many different types of data
The dashboard feature of a LINE Official Account lets you check a wide range of data, including changes in your friend count, block count, number of messages sent, number of messages sent/received, timeline post views, coupon and shop card usage, and survey results.
By connecting your Shopify store with LINE, you can access data that Shopify's customer management features alone can't provide.
Streamline customer support
A LINE Official Account lets you use a chatbot feature to set up automated responses to questions. By setting up auto-responses in advance for frequently asked questions, you can reduce the time spent handling inquiries.
It's also a good idea to add a link to your LINE Official Account on your Shopify store, consolidating your inquiry channel into LINE.
Using a Shopify app such as Channel Talk lets you centrally manage inquiries that come in through your LINE Official Account and respond to questions individually.
Enable 1-on-1 communication
One strength of a physical store is 1-on-1 customer service. If you run an apparel store, you probably know from experience that 1-on-1 service can dramatically increase purchase rates.
Using a LINE Official Account lets you offer that same kind of 1-on-1 customer service through chat.
Broadcast announcements and coupons all at once
A LINE Official Account has a broadcast messaging feature that lets you send announcements, coupons, sale information, and more all at once to your registered users.
Segmented messaging is also possible, letting you send only to customers who purchased a specific product, or only to female customers, for example.
Alongside LINE, email newsletters are another effective way to broadcast announcements and coupons to customers. The article below covers the benefits of email marketing on Shopify and recommends apps for sending newsletters. Take a look.
Drawbacks of Using LINE
The drawbacks of using LINE include the following
- Cost
- Being blocked by friends
Let's look at each in detail.
Cost
A LINE Official Account can be started for free, but costs are incurred once your monthly message volume exceeds a certain threshold. If you use a Shopify app or external service to connect with your Shopify store, you'll also incur the monthly fee for that app or service.
Being blocked by friends
LINE makes it easy for users to block a friend. Once blocked, you can no longer deliver messages to them. Sending messages too frequently increases the risk of being blocked, so it's worth optimizing your send frequency, using segmented messaging, and otherwise keeping your messaging to the necessary minimum.
LINE Use Cases at E-Commerce Stores
Video messaging tripled sales of an original product
Video has the advantage of conveying more information and having more impact than a still image, making it easier to spark users' interest in a product. As Mr. Matayoshi puts it, "video pairs well with LINE's immediacy" — and indeed, after distributing a promotional video for an original mattress through their LINE Official Account, the number of units sold per month rose to three times what it was before the video was sent.
Inquiries up 20% year over year on average
As more people use overseas shopping sites, some feel anxious about purchasing and paying in an environment that doesn't support Japanese. This business accepts requests and consultations for import-proxy services through LINE chat to address that concern. To reach more people, they used a discount coupon to encourage friend adds on their LINE Official Account. After opening the account, inquiries increased by about 20% year over year on average.

Recommended Features for Using LINE with Shopify
Buy Button
The Buy Button is a native Shopify feature that lets you publish products you manage in Shopify not just on your Shopify store, but anywhere on the web, so they can be purchased from any page.
The Buy Button is free to use. Copy the embed code it generates and embed it in a LINE message, and users will be able to add the product to their cart directly from that message.
It's a great option if you want to try out LINE without spending anything.
