CartSync ‑ Persistent Cart

Your customers' carts follow them — phone, laptop, or tablet. No lost carts, no re-adding items.

CartSync saves every logged-in customer's cart and restores it on any device — automatically. Set merge or replace mode, sync in the background on every cart change, and send automated emails for price drops, back-in-stock alerts, and idle carts. Connects to Klaviyo or your own SMTP. Works with any Shopify theme, no code required. Built with official Shopify APIs.
