See every featureBest sellers get buried when collections sort by date — costing you conversions every day. Best Seller Sync automates merchandising with real paid order data: units, revenue, orders, or GA4 engagement. Schedule pins, exclude products, push sold-out down, and auto-sync across multiple collections. Grade products A, B, or C. Set a custom look-back window, apply sort rules, track rank trends.
Automated returns and exchanges from start to finish. Customers submit requests through a branded portal that validates orders and queues them in your inbox. Approve in one click and the refund, courier pickup, and customer notifications fire automatically. What used to take 15 minutes per return takes 30 seconds. Built for stores that want returns out of email threads, spreadsheets, and 5 separate dashboards.
