Buena aplicación, facil de usar. Aparecen todos los pedidos de todas las plataformas en una misma pagina con lo que hace que todo sea mas rapido y facil de gestionar. La atención al usuario es muy buena, son muy amables y te ayudan con todo. Recomendado al 100%

4Seller has been a great solution for managing our multichannel business. The integration with Shopify and Amazon FBA works very well and saves us a huge amount of time every day. The interface is clear, synchronization is fast, and the support team is responsive and helpful whenever needed. We especially appreciate the automation features for orders, inventory, and marketplace management. A very powerful tool for scaling an e-commerce business efficiently. Highly recommended!

Vikta has been an absolute pleasure guiding me through this App. Thank you for all the help!

Really impressed

I’ve had a great experience using 4Seller for my e-commerce business. This app is not only useful for Shopify, but also for managing marketplace integrations across different sales channels. It is a powerful all-in-one solution for product listings, inventory synchronization, order management, and keeping everything organized in one place. In my opinion, 4Seller can easily replace many of the paid tools available for marketplace integration and multi-channel selling. It offers strong functionality, saves time, and helps simplify operations without needing to rely on multiple separate apps or services. What stands out the most is the support team. Setup and integrations can sometimes be complicated with e-commerce tools, but 4Seller makes the process much easier thanks to their responsive and knowledgeable support. Special shout out to Vikta for her professionalism, patience, and excellent assistance. She was very helpful, clear, and attentive throughout the process, making sure everything was handled properly and that my questions were answered. Overall, 4Seller is a powerful and reliable app for any online seller looking to streamline marketplace integrations, manage inventory, simplify orders, and save time. Highly recommended.

★★★★★ We’ve had an excellent experience with 4Seller from day one. The onboarding was handled through a dedicated one-to-one Zoom session, which made the setup process clear, efficient, and tailored to our business model. Having direct access to a knowledgeable specialist meant we could get everything configured correctly without the usual trial-and-error you see with other platforms. As a global Amazon brand, we rely heavily on accurate inventory and fulfilment workflows, and 4Seller has enabled us to seamlessly integrate TikTok Shop with our Amazon MCF stock, as well as connect Shopify for multi-channel fulfilment. The synchronisation is reliable and has significantly reduced manual intervention across regions. We are now also exploring Temu integration due to the additional functionality available within the platform, which shows how scalable the system is as we expand into new marketplaces. Overall, it’s a powerful solution backed by responsive customer service and a team that understands cross-border e-commerce. An amazing product that genuinely simplifies multi-channel operations.

This is by far one of the best ERP systems I have used! Syncs data across channels seamlessly and has lots shipping integrations (as well as the marketplace options, which can be purchased directly in 4 seller). It's always a big job setting up an ERP to work across all channels but I had 4 seller up and running in 48 hours and Lydia in the support team helped at every step and made sure everything was working as expected. Great App!!!

Essential for multi-platform sellers! This app makes managing listings across different marketplaces effortless. Syncing is fast, bulk edits save time, and the interface is super easy to use. A real productivity boost—highly recommended! Joline Chan help me in the process
