Richpanel lets you manage live chat communication on your store with ease. Besides having chat agents responding to visitor queries, you can set up automated flows that will react to particular actions, give product recommendations, share discount coupons, etc. 

Apart from a live chat, you can manage conversations from Facebook, Instagram, and Amazon, as well as sync the data for email and SMS campaigns. Richpanel features 30+ integrations with other Shopify apps to help you collect feedback, manage subscriptions, assign loyalty points, and so on.  

The Richpanel app also lets you build a self-service widget. With it, your customers will be able to fill out return data, check order statuses, and access other valuable information. 

There’s a free version that includes a live chat with a multi-channel inbox but is limited to 100 conversations. Paid plans are Starter ($200 per month), Regular ($500), and Pro ($800). They will provide you with more conversations (1k, 2k, and 5k, respectively) and additional features: for instance, a basic help center in Starter, social media integrations and CSAT surveys in Regular, and multi-store / multi-language support in Pro.
