Shopify Marketplace Connect

I would consider myself a heavy user, this app in the beginning really shot me to a new level in revenue. However, with recent Amazon API changes, nothing seems to work and support (while kind of helpful) can't seem to fix the issue. I haven't been able to successfully list a product in months. Images seem to break, errors left and right that nobody seem to know how to fix. I hate to write a bad review from these guys because of how good things once were but as of recently, I can't recommend this to anyone who relies on Amazon. eBay and Etsy tend to post product just fine

The app simply does not work anymore. Since their latest update none of my listings from shopify can be listed on Amazon. None of the settings or mapped fields have changed. Just an endless list of error codes. I have contacted support who suggest I manually import all my listings on seller central which is exactly what I am trying to avoid. They admit that the app won't upload products, say they are working on it but cannot give any timescale for a solution. The support staff are very helpful, although that doesn't do much good if the product doesn't work.

The most annoying thing is it worked perfectly before the 'update'

After a call with support I was assured daily updates, unsurprisingly that hasn't materialised and I am left chasing for any update at all.

In short the support staff are great, the product seems to be useless

Avoid like your business depends on it.

I don't like leaving negative reviews, ever, but this app has been nothing but trouble.

It didn't sync my products with eBay properly, which was sorted after dealing with their support team. But then, without warning or a notification, it overrode my shipping information TWICE, even after I added them to the app AND eBay, leading to customers getting free delivery for large parcels where they shouldn't have (with my business covering the costs and therefore losing money on the sales). When speaking to support, they essentially blamed me, saying I didn't input info correctly - not sure why I'd manually select ~20 of 250 products to have shipping costs, rather than ticking "select all"...

They oversold one of my products, (it was out of stock on my website, but it was sold on eBay anyway) which I had to source with no notice so I didn't let down a new customer.

The fees are not clear and certain members of the support team were rude and extremely unhelpful, when I tried to resolve the issues and move forwards.

Worst of all, they refused to reimburse any of the additional costs I'd incurred and blamed me for the issues I faced.

I've spent so long on this app and these issues, it would have been easier, less stress & less cost to my small business if I'd manually uploaded everything to eBay - which I will be doing from now on.

Avoid.

The app worked really well for us initially, but we ran into a major issue when all of our Etsy listings were suddenly deactivated without warning. It took four days of back-and-forth with support to finally be told it was due to a SKU-to-Etsy ID mapping issue — something we had never changed or touched ourselves.

While the support team were polite and tried to help, the issue should have been escalated much sooner. We lost valuable time and sales while waiting for a proper explanation. In the end, we had to uninstall and reinstall the app just to get our listings live again.

This experience was frustrating and stressful, especially for a small business relying on consistent visibility. If you're using the app, keep an eye on your listings and be aware that any sudden change might be related to hidden mapping settings or renewal of the app. A quicker response and clearer guidance would have made a big difference.

**UPDATE #2**
Their customer support is diabolical. At this point i don't know if they're trolling customers or hire infants. They will contradict, they'll make you wait forever between responses and most replies will infuriate you with its lack of understanding the matter or their own app functionality. I WISH WE COULD RATE THEM -10.

**UPDATE #1**
Your app gets worse and worse day by day. Live-chat support takes hours to say a simple "hello" and the app is so littered w/ bugs it is scary. We are starting to regret using your app and migrating to another app is a large undertaking when dealing with 35K skus. You're owned by Shopify — why isn't Shopify fixing these issues?

**ORIGINAL REVIEW**
You'll be told that their connections working fine until you start facing show-stopper errors. You'll also be told that you'll always have 24/7 live-agent chat support until you do NOT. Here we are 2 days in a row trying their live-chat and there are NO live agents at all. And they aren't responding on the 'submit message' emails for now two days. We did not expect such unprofessional treatment from Shopify.

As others have noted in their reviews, this app's functionality has significantly declined since Shopify acquired Codisto. The app overrides your existing eBay or Etsy data, which can damage your store and even lead to policy violations that may result in a suspension.

The support and development teams work closely together in the same office, yet they present themselves as if they operate from multiple locations and departments. This creates a false impression that resolving issues will take a long time.

The support team consistently refuses to acknowledge problems with their application, instead blaming platforms like Etsy, Amazon, or eBay for any issues. We also use other apps without experiencing problems, which we find depend on our clients’ preferences and budgets.

Lastly, I would advise caution when believing everything they say. There are online threads that highlight deceptive tactics they use to discourage users from uninstalling the app or leaving negative reviews.

PS: Nikki, your gaslighting stating other users have not left disappointing reviews is laughable. Your review rate is 4.3 and that means roughly 16% of users who left a review are not satisfied with the application.

This app stopped sending tracking information to Amazon. In response, Amazon dezactivated all our listings for poor FBM shipping.

didnt work for my listings as they were customized. I did say that in the beginning and was assured it would work. Then when i linked the listings it erased data from my etsy store, I had to remove the app and now my etsy listings are not allowing me to edit them. extremely disappointed, and potentially ruined my etsy store.

This app team has the most ignorant support team I have ever experienced in 8 years of ecommerce. Not only do they not listen, they constantly cause issues and ignore bugs on their own accord. It's not surprising that this app is cheap, because nobody in their right mind would pay for this level of service.

This app works and then doesn’t. It kept flipping my FBA listings to MCF and they couldn’t figure out why where all the settings were fine. Not good.
