A LINE integration app from Japan that connects Shopify customer data and LINE
CRM PLUS on LINE is a Shopify app from SocialPLUS Inc. in Tokyo. It links Shopify customers with friends of your LINE official account (ID linking) and enables LINE messaging based on Shopify customer and purchase data. It makes possible sends that are hard with a LINE official account alone, such as "only to people who bought" or "to people who left items in their cart".
It has been on the Shopify App Store since 2020, and was announced to be running on more than 2,500 Shopify stores as of the end of December 2025. Its App Store rating is 5.0 (39 reviews as of November 2, 2026).

CRM PLUS on LINE's key features
ID linking (on the thank-you page and account page)

Encourage LINE linking and friend adds right after purchase and on the account page
You can add blocks encouraging LINE linking and friend adds to the order thank-you page and the account page. They can show the benefits of linking, such as "get shipping updates on LINE", and are set up without code. Once customers link, you can send them LINE messages based on Shopify customer data.
Abandoned cart and checkout reminders

Notify customers on LINE when they leave items behind
Reminders for customers who left during checkout are available from the free plan, and reminders for customers who left items in their cart from the Standard plan. LINE is noticed more readily than email, which helps reduce missed purchases.
Other key features
- Segmented messages: Send LINE to customers filtered by Shopify customer tags or segments
- Step messages: Automatically send a sequence triggered by shipping or ID linking
- Shopify Flow integration: Combine with Shopify's free workflow app for flexible automation
- Restock alerts: Notify customers on LINE in combination with the restock app "Back in Stock"
- Tabbed rich menus: Customers can switch between multiple rich menus
- Social login and membership cards: Six social login providers including LINE, and a LINE mini app membership card (for Shopify Plus)
It also forwards LINE webhook URLs, so it is easy to use alongside other LINE tools you already have.

| Entry | $10 | Up to 300 | Same as Free |

| Advanced | From $200 | Unlimited (usage-based) | For Shopify Plus; social login, LINE mini app membership card and more |
Paid options are also available, such as a "research and acquisition package" bundling pop-ups and friend-add source analysis ($150/month) and "LINE notification messages", which deliver order and shipping confirmations by phone number ($300/month). Plans are never upgraded automatically; you change them from the dashboard.
To send LINE messages, LINE official account fees and message charges are billed separately by LY Corporation.

Caveats to know before using CRM PLUS on LINE
The channel is LINE only
CRM PLUS on LINE is dedicated to LINE messaging. To also reach customers by email, you combine it with an email app, which splits tools and sends across two places.
Advanced features come with higher plans or options
Abandoned cart reminders need Standard or above, and LINE notification messages are a paid option. Which plan you need depends on the campaigns you want to run, so check before adopting it.
Shopify Plus features require the Advanced plan (from $200/month)
Features for Shopify Plus, such as social login and the LINE mini app membership card, require the Advanced plan (from $200/month, usage-based). Even while you have few ID-linked users, using these features means paying at least $200 a month.
Knowing Shopify Flow helps with automation
Detailed automation is set up in combination with Shopify Flow. Creating richly designed messages may also require knowledge of Flex Message, so it takes some familiarity to make full use of it.
Stores CRM PLUS on LINE suits
- Stores that focus their customer contact on LINE and want to go deep on LINE features
- Shopify Plus stores that want social login or a LINE mini app membership card
- Stores that want a shared membership card for physical stores and ecommerce
- Stores that want to develop their use of LINE with support in Japanese
Summary
CRM PLUS on LINE is dedicated to connecting Shopify and LINE, with everything needed for LINE — from ID linking to rich menus and social login. You can try it for free and support in Japanese is strong, making it a strong choice for stores that want to connect with customers mainly through LINE.
On the other hand, its channel is limited to LINE, and some campaigns require higher plans or paid options — points to check before adopting it.
If you want email and LINE in one tool: StoreCRM as an option
If you want to run email as well as LINE in the same tool, StoreCRM, which sends email and LINE from one dashboard, is another option. StoreCRM is a CRM app for Shopify stores in Japan that also includes back-in-stock alerts and wishlists.
| CRM PLUS on LINE | StoreCRM | |
|---|---|---|
| Channels | LINE | Email, LINE |
| Free tier | Up to 100 linked users | Up to 300 |
| Setting up automation | Combined with Shopify Flow | Flow editor in the app |
