Shopify Marketplace Connect

It's not quite as easy as the video makes it appertains to sync your listings however, with the fantastic support I received from Mark @ Codisto today, he helped me understand the importance of making sure you have rock solid UPC & SKU codes in order for the systems to all integrate properly. Thank you for the 6 star support!

Newest Final review update; 8:32 am CST 12-27-2019 This review is in regards to a work-around for use with Amazon Handmade. There are a growing number of indications that there is a good work-around for Handmade inventory and price sync when the product is loaded manually on Handmade. A guide is promised and I will probably be back to re-install once the guide is published. Straight product to product seems to work fine for syncing inventory and price; variant work remains in progress. I am leaving the app with solid 4 stars. Good work Codisto. And Thank you.
Final review: 7:27 am CST 12-15-19 This app was installed so I could see for myself about an off-label use with Amazon Handmade to sync inventory with Shopify; answers from Codisto about this had been inconsistent so I decided to check it out myself.

Overall app review is 3 stars, but I will be happy try this app again in future.
I did not test the app with regular Amazon. If this is your situation, I recommend trying the app!
Support gets 5 stars as they are knowledgeable, have responded and tried to help me.
Ebay part gets 5 stars; it seems to work pretty well and I did not loose any data when I tested an inventory sync with Shopify.
Amazon Handmade off-label work around gets 1 star. Not yet ready for prime time. The inventory sync seems to work but at an unacceptable cost; there is a good bit more chatter going back and forth between Shopify and Handmade than I understood. The chatter produces with some serious results like erasing product descriptions, changing production times, removing category assignments and removing listings from the Amazon catalog entirely. And once you have synced your Amazon Handmade, whatever you do, DO NOT disable the offer as it produces some of the above consequences, I was told.
I will be following Codisto in their facebook group to watch for updates and will hopefully try this app in future when work around bugs are worked out or a definitive connection is made with Handmade. And maybe even the addition of Etsy.

Update: 8:07 am CST 12-11-2019 5 stars for support with Noel. App is set up and seems to be working as advertised with a workaround for Amazon Handmade. The Amazon Handmade products (loaded manually on Amazon Handmade) have synced quantity with Shopify. The issue with Amazon Handmade seems to be the UPC which is not required on handmade goods. I will continue to update this review as the functions are tested. I really appreciate support working to help over the phone. This company clearly is interested in becoming a success.

Update: 7:09 pm CST 12-8-2019 Thanks to Noel, on the other side of the world, for helping with set up; 5 stars to Noel! There was a timing issue during set up which was explained well. And Noel was able to talk me through part of set up with Amazon which was most helpful. Codisto support is working with me at my own pace, since this app is way over my head. Situation is looking favorable for inventory sync with Amazon Handmade. And being able to talk on the phone with Noel is GREATLY appreciated. Now let's see how the app runs and works.
This will be a running review, updates at the top of the thread. App is installed, but not yet set up. 3 stars. Not for beginners. Information from support is conflicting at times, so am trying the app out to see for myself. My need is to be able to post all my handmade items for sale on all my channels and have the inventories synced back through Shopify so I don't oversell. Amazon Handmade is an Amazon outlier with respect to most apps. I have received info from one support person who says that if products are listed manually on Amazon Handmade, they will sync back to Shopify to keep inventory straight. This remains to be seen.
This morning I processed a return/refund on Amazon Handmade and then got a new identical paid order showing up on my Shopify hub coming from Codisto; pretty sure this is a glitch, as I cannot confirm the purchase on Amazon. Inquiry sent to support who has been responsive so far, though probably in a different time zone.

Me parece buena aplicacion, tal vez casi excelente, es una app super útil, solamente le hecho en falta Aliexprees Seller! estoy intentando buscar una app para subir productos masivamente

At First the app was not doing what I needed, after getting a hold of customer support I was able to walk though the steps needed to make the app work well. The app has a lot of moving parts for it all work well.

If you are doing eBay or Etsy this app is awesome! As others have said, connecting Amazon is a bear. In a perfect world, and once you get it working it should be just as easy as the other platforms. There are still a lot of bugs they have to work out as the field mappings are a guessing game and huge time sync as it is very slow to communicate with Amazon's API. Overall its still a great app.

Usata per connettere EBAY ed AMAZON. Facile da usare; super risposta da parte dell'assistenza per un piccolo problema, risolto in 5 minuti. Suggerita.

Ich hatte eine tolle Unterstützung durch Adrian, und bin sehr zuversichtlich alles gut hinzubekommen

Its been difficult to use this app

Seems to work but you will need to play around with it and likely contact support to get your first listing active. Four stars as the app itself some things are not intuitive but I would give the live chat support 5 stars for being so helpful.

Just converted from Codisto to this app for Amazon feed and there were some bugs in the app which weren't picked up during testing. Fortunately they were able to fix these quickly. It would have been better if they had found these out before launching the product, but their response to solving the problem was good.
