CRM PLUS on LINE vs Singleton | Verify Customersfor Shopify (2026)
CRM PLUS on LINE and Singleton | Verify Customers are both 5-star rated apps in the Accounts and login category on the Shopify app store, but they serve very different purposes. CRM PLUS on LINE focuses on enhancing customer engagement through LINE messaging automation. Its strength lies in its ability to leverage customer data, like tags and purchase history, to personalize and automate LINE communication. Singleton | Verify Customers, on the other hand, centers on access control and customer validation. It empowers merchants to filter access to pricing and purchasing features based on approval status, offering enhanced control over who can view and interact with their products. CRM PLUS on LINE is ideal for merchants looking to improve customer retention and drive sales through targeted LINE campaigns, particularly in regions where LINE is a dominant communication platform.

Our Verdict
If your priority is leveraging LINE for customer engagement and automated messaging, CRM PLUS on LINE is the clear choice, especially if your target audience heavily uses the LINE platform. The integration with Shopify Flow and initial setup support makes it appealing. However, if your business model hinges on controlling access to pricing and products, validating customers, and creating custom registration forms, Singleton | Verify Customers is the superior solution. It gives you fine-grained control over who can see what in your store, which is crucial for wholesale, membership, or regulated product businesses.
While both apps have excellent ratings, the feature set and description of each app strongly indicates which specific needs each one would meet. A merchant would not replace one with the other, since they satisfy different requirements.
