Shopify Marketplace Connect

I only used this app for a Walmart.com listing. I'm not sure how it performs for other marketplaces.

Here were my issues with Walmart:
1) The listing on Walmart was never the same as the product information on Shopify. I tried multiple times and ways to edit something as basic as the title showing up for the Walmart listing and even after chatting with support multiple times, I was unable to change the Walmart listing title or edit the description completely. The description was pretty much always a bit off
2) Marketplace Connect should see from my Shopify account that I'm shipping all my orders through Amazon MCF. It turns out that Walmart does not allow competitor carriers to be used so Marketplace Connect kept sending Walmart my shipping information and Walmart ignored it. Then they cancelled all my orders after all the products had already been delivered to customers and gave customers their money back. Marketplace Connect should have been able to warn me that the carrier I was using was not compatible with Walmart as Walmart has a list of carriers they can easily compare against.

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

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.

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!

It's a good app when it works. But poor support and multiple months of downtime, technical errors, and unresponsiveness make it hard to recommend. Further, they continue to charge during their downtime. Customer service is quick to respond and is great for general inquiries but very slow to fix any bugs or problems. Unfortunately, you will also be ignored by their support team if you ask any difficult questions (i.e when will the app work again, ETA's on technical bugs). If you have a large catalog and your business is heavily dependent on the communication between Shopify and Amazon I would not recommend this app, it is not reliable enough.

This app keeps having issues with ebay and Amazon, Looks like we will be looking for a new provider. customer service and support inst high on the list of things for this company.
