CartSync ‑ Persistent Cart

CartSync automatically saves and restores shopping carts for logged-in customers across all devices — phone, laptop, or tablet. No more lost carts or customers re-adding items. The app syncs carts in the background with every cart change and lets you choose between merge or replace mode when restoring. Send automated emails for price drops, back-in-stock alerts, low inventory notifications, and idle carts to recover sales. Connect through Klaviyo or your own SMTP for email delivery. Track recovered revenue and conversion data with built-in analytics. Works with any Shopify theme using official Shopify APIs — no coding required.
