Amazon MCF by ByteStand

We love this APP and let me tell you, customer service is so easy to work with, they helped me step by step check my setup. USA based and very helpful, answered immediately. I recommend this company if you are big or small.

Bytestand is awesome and the support is phenomenal! most useful app on shopify by far! The support is second to none, they really help out and resolve any issue any time I have one

App works great. Easy to install and sync. Cara was amazing, fast and great support received. She did a great video for me to follow and she also was able to fix issues within the same day the ticket was submitted.

In my years of working with online companies and services, it's rare to encounter the level of support that Cara from ByteStand provided. She truly went above and beyond to resolve the issue I faced. Not only did she address the problem promptly, but she also took the initiative to record short instructional videos, walking through each step of the process as she fixed the issue. This not only solved the immediate issue but also empowered me to learn and troubleshoot similar problems in the future. Cara's dedication and expertise were evident throughout, and I greatly appreciate her promptness and effectiveness in resolving the issue. She's truly exceptional at what she does.

Since the implementation of the latest update (known as FLEX, launched May 2024) our store has been broken - orders not being filled automatically, orders being marked as rejected in Shopify but actually processed in Amazon leading to duplicate orders, and our non-Amazon fulfilled orders no longer being fulfilled automatically. Staff I interacted with seemed nice and tried to be helpful, but in the end it's still broken and the result was "this is Shopify's fault, not ours, so nothing we can do about it. If you're a simple store shipping in one region and only using Amazon for fulfillment, then this may work for you. But if your business is slightly more complex, sells products in multiple countries using multiple third parties for fulfillment, then this product in its current state will not meet your needs and may interrupt the non-Amazon automations you have. We're exploring other options.
