Shopify Marketplace Connect

To be honest, I thought it would be easy to sync listings to different marketplaces. So far I have been able to list my products on Etsy and eBay successfully, but I am struggling a lot with Amazon.

Syncing products to Amazon has been a pain, with syncing failing due to various different reasons and for the past few weeks the Marketplace Connect page in Shopify Admin has been either super-slow (30-60 seconds per page load) or not responding at all due to Codesto API responding slowly or with a FastCGI error codes

I am still trying to connect to the rest of the Amazon marketplaces internationally, but due to the page loading and sync issues it has been a painful experience so far

I tried to connect to our etsy store. That app is really hard to understand, I'd say impossible. Terrible interface. Random products were exported and I could not get to the bottom why these. Bulk editing does not work. Filtering products does not really work. All in all I had to delete the app cause it was making my life harder instead of easier.

My overall experience with the app isn't great as I'm not finding it very user friendly and guides on how to use it aren't visible. However I've just had a positive customer service experience with Lou via email- she was very helpful, answered all my questions and provided links to further information I need. Her responses were prompt too.

The app continued to push product to online marketplaces even after we archived Shopify listings and manually shut the links down. We had to cancel multiple orders because of it.

Worked great until Ebay started giving me errors today. Customer service was unhelpful. I don't have time to mess around so I just installed a different app for Ebay channel, which is really annoying because now I have to update all the listings and I'll lose followers.

Standard so-so, Shopify-built app that reminds me of Shopify Flow. It does some things but not the things you want. It does not integrate with useful new features that Shopify has introduced - like Metafields. You spend many, many hours figuring out that it does not do these things.

Do you use a metafield to hold your UPC data? You're out of luck.
Need to refresh a SKU that you've replaced with UPC data so that you can sell it on eBay? You're out of luck.
Need to reset a listing that has errored out? You're out of luck.

If you have a customized Shopify store you're not going to enjoy this.

I've used this on and off for years. Has been very buggy in the past and 'gotten us in trouble' with amazon because randomly stopped syncing. I see that they now are charging 1% of revenue of synced listings, on top of their app charges, which I find unbelievably greedy. This must be some kind of monopolistic advantage. Anyway, you can't just push your listings to Amazon and be done - AZ is super complex and the listings must be highly customized.
After 5-8 years we are going to find another app due to this greedy policy change.
I suspect they changed their name from Codisto in order to avoid their reputation of poor service in the past. For some reason this is Shopify's go to recommendation and I have no idea why.

This extension doesn’t work inside Shopify app or admin from browser, for iPads or iPhones.

the app has some restrictions with item specifics and compared to other optimisation software. however, the main issue i have had is, i recently had items listed on ebay but I wanted to modify the products in Shopify and add other variations. So i ended the eBay listings, made the modifications and tried to list the products again as new. however they don't list, they is some digital footprint that's blocking them from listing. i have modified hundreds of items so this is not just 1 or 2 products. After over 2 weeks of codisto looking into this, the resolution they have said, i need to change the spelling of the variation "Colour" so its spelt wrong and also change the SKU's (which is not an option as these control the stock levels from my suppliers)

This ridiculous fix has taken over 2 weeks, i generally get i message per day, and even if i reply immediately I generally don't get a response for 24 hours

Codisto has probably the worst customer service that I have ever encountered with. They just dont understand the problems that seller face day to day - as a result has zero empathy. Such a waste!
