See every featureStop losing sales when customers switch devices. Our app automatically syncs carts for logged-in users, ensuring items added on mobile are ready on desktop instantly. This seamless journey removes friction, slashes abandonment, and boosts conversions. Whether they start on a phone or a laptop, their cart follows them. Professional, effortless, and designed to grow your revenue.
Shoppers browse on a phone and buy on a laptop. Cart Relay saves a signed-in customer's cart against their customer account and puts it back when they sign in on another device. No link to click, no code to enter. If the second device already has a cart, the two are combined: quantities of shared items add up and no line is dropped.
