The app is convenient and easy to use. Customer support responds and resolves issues very quickly. Great experience—special thanks to Joline Chan. I will definitely recommend this app to others.

ottimo e buon servizio. una gran piattaforma per collegare tutti i marketplace. non ho collegato la gestione del inventario ne i pagamenti ne spedizioni. ho utilizzato solo la migrazione ed è super ottima.

We’ve been using 4SELLER for a few months now and it has drastically improved the way we manage our listings, orders, and inventory across platforms. Syncing products between Shopify and marketplaces like Amazon, eBay, Otto, and Kaufland is incredibly smooth. No more manual updates or overselling! The interface is clean and user-friendly, and the automation features save us hours every week. What really stands out is their support team—quick, knowledgeable, and always ready to help. Highly recommend 4SELLER if you’re serious about scaling your business across multiple channels without the usual headaches!

The system automatically syncs my inventory across platforms, so I never have to worry about overselling or stockouts. Thanks for Joline kind explanation.

I've been using 4Seller to manage products or inventory across my TikTok and Shopify stores. In the past, the time spent on manually listing products could now be entirely handled by one person, one system, and one click. Inventory deduction has always been a headache for sellers like us who operate across multiple platforms and stores. However, 4Seller's inventory synchronization rules can fully automate this process for me, ensuring that whenever an order is placed in one store, the corresponding inventory counts in other stores are synchronized and reduced accordingly. This eliminates the need for manually handling such complex processes anymore.

easy to use, setup for channels quick

Joline was very helpful - thank you
