Amplius Customer Fields vs Persistent Cart ‑ Sync Devicesfor Shopify (2026)
Amplius Customer Fields and Persistent Cart ‑ Sync Devices, while both categorized under 'Customer Loyalty', serve fundamentally different purposes. Amplius Customer Fields focuses on enhancing customer data collection and personalization by enabling merchants to add custom fields to registration and account pages, storing the data directly in metafields. This caters to merchants needing specific customer information for personalized experiences, marketing segmentation, or operational requirements. Persistent Cart, on the other hand, concentrates on improving the shopping experience and reducing cart abandonment by ensuring carts are synced across multiple devices, eliminating the frustration of lost carts when customers switch between devices. It targets merchants aiming to increase conversions, order value, and customer retention through a seamless shopping experience. Both apps offer distinct value propositions within the broader customer loyalty spectrum.
