What merchants think

Feedback submitted

Merchants recommend this app for reliably syncing inventory and orders between Shopify and Amazon, including multiple marketplaces. It reduces manual work even for large catalogs and simplifies listing, FBA/FBM setups, and switching fulfillment methods. Many highlight powerful, flexible settings and better value than alternatives. Onboarding is described as easy, and support as fast, friendly, and proactive, with long‑term merchants reporting smooth, stress‑free fulfillment.

We were having trouble managing our Shopify and Amazon integration using Marketplace Connect. We decided to switch to this app and have no regrets. The app does a great job of syncing our orders and our inventory between Shopify and Amazon. Their customer service team is very helpful and knowledgeable and assisted us with onboarding and troubleshooting issues.

Look elsewhere if you want an app you can rely on. We've seen signs of increased unreliability with strange behaviour and technical glitches for some time now. On Tuesday all order imports from and tracking updates pushed to Amazon failed completely, and the app interface would not load at all. We've not been able to get any meaningful response from customer service, and eventually had to help ourselves through reinstalling the app... which lost all settings and required us to set everything back up again from scratch. After this, however, the automatic order sync is still not working... and we have to manually check for new orders and trigger the imports. The complete lack of service/assistance during such a critical incident is simply unacceptable.

CS Amazon Sync has excellent customer service. I had an issue with my Amazon quantity sync, and their support team helped me quickly and professionally. They understood the problem, fixed the issue, and made sure everything was working properly. The app is very useful for managing Shopify and Amazon inventory, and their support gives extra confidence. Highly recommended for sellers who need reliable Amazon sync service.

dire pessima app è poco. Abbiamo testato i 14 giorni in free trial, all'installazione senza creare regole o settare nulla, ha modificato prezzi e giacenze nell'account amazon bloccando lo stesso e generando gravi problematiche, oltre a questo a richiesta di assistenza urgente sono passati 10 giorni e nessuno ha risposto a nulla, segnaleremo direttamente la app a shopify in quanto effettuati screen di tutte le conversazioni e degli errori che hanno generato senza intervenire e rimborsare i danni causati. Ovviamente è una azienda dall'altra parte del mondo e per 4000€ di danno il costo legale sarebbe maggiore ma stiamo capendo se vale la pena e addebitabili i costi internazionali del legale. App pessima e pessima assistenza.

Have gone through rough patches lately with support and product function, but after some debugging it appears to be running as intended - and then not... this program is a real crap shoot.

I cannot give it a higher rating until they work their system bugs. Very unstable and unreliable right now.

Support is very slow in advising on updates and/or fixes.

Will review over the coming weeks and revise if necessary.
