Shopify Marketplace Connect

I do not recommend this add on, when it works its great but when it doesn't work you end up with overselling items and listings not syncing. I have been a user for a long time but for the past month there have been breaking issues and when you reach out to support they say "there is a large backlog sorry"

This is my opinion only. My opinion is formed after evaluating it for 2 weeks along with competing products. Regarding my experience with it over the past few days. I totally agree. This is an absolutely senseless app , and with regard to being intuitive (like the many , many other similiar apps I use daily) This mess gets a zero regarding being intuitive, and the process flow ..... I wouldn;'t even call it that, because no process flow exists. Stay away.

For a core Shopify app this is not well supported. Be warned it will only match the first 100 product variants in a family, the rest won't sync. Support doesn't seem willing to upgrade their systems to support the now 2,000 variants you can have. The fact that Shopify promotes that you can sell on Marketplaces but doesn't give you a fully function app feels like misleading advertising to me.

Marketplace Connect used to be a useful app, but at the moment it simply cannot be relied on to run an eBay store.

I am experiencing serious syncing problems with eBay. Images are not updating correctly, inventory is failing to sync properly, and I have now had a main product sell out on eBay without the stock being correctly updated. This creates a genuine risk of overselling and damage to an established eBay listing.

The most frustrating part is that this does not appear to be an isolated problem. Other merchants are reporting very similar issues, yet there seems to be no clear explanation of what is happening or when it will be properly resolved.

When an app is responsible for syncing listings, images and stock between Shopify and eBay, reliability is absolutely essential. These aren’t minor glitches — they directly affect sales and seller performance.

Marketplace Connect is a great idea when it works, but in its current state I simply cannot trust it with my inventory or eBay listings.

I hope Shopify treats the current problems seriously and gets the app back to being something merchants can depend on.

I have been using this app since it was Codisto and it was wonderful at that time. I'm not sure what happened but now it's absolutely horrible. Everything is just error errors errors. Pictures dont sync inventory doesn't sync pricing doesn't sync.

Now items are overselling on eBay, that have been out of stock for days on Shopify caused me to have to cancel Ebay orders putting my Ebay account at Jeopardy.

Support just keeps giving excuse after excuse that they're working on it, but nothing ever gets fixed absolutely horrible. I will be uninstalling this app and looking for a better solution.

Avoid this app at all costs! I have been using it since it was Codisto, and I never knew how bad it was at everything until I was forced to find another app. I never liked using it, but what pushed me over the edge was when it pretty much stopped syncing photos to eBay two weeks ago. Maybe 10% of my new listings actually got published, some of which took 2 or 3 days to publish.

I set up demo meetings to evaluate 3 other apps, hoping I could find one that would work. This morning I started playing with LitCommerce, and it is honestly so good that I canceled my other two meetings. It is so well designed and intuitive that all I needed was a 5 minute setup video. By this afternoon I had all of my templates set up, all 346 of my items synced to the new app and published on eBay (with only a couple of errors), and THIS crappy app uninstalled!

No telling how much money Marketplace Connect cost me in wasted time and lost sales over the last couple of weeks!

Same problems as Emma Jean's review of August 17, 2026. Over the last year I have had REPEATED problems of pictures not syncing properly with eBay. Marketplace Connect would eventually fix them, but would tell me that the issue was on eBay's end and they are trying to resolve it. Now, in the last 30 days, no new pictures will be uploaded to current listings. Such as we already have a listing, have added additional variants with new SKUs and pictures, but the pictures won't upload. Now, in the last 15 days, I can't even create new listings on ebay. When I contact customer support, it takes about 24 hours to get a response (during the week - no weekend support) and get a repeated response - 'it's eBay's fault'. After 15 days of not being able to create new listings I've had enough. Will start experimenting with other apps.

Never write reviews but this one is needed. Have gone back and forth with support regarding this App all of a sudden not uploading to Ebay properly. At first you could get Live Support and then it switched to submitting a request overnight. I've had no response in over a week. App is great when it works. Super disappointing for a Shopify App. I'm over the poor support across the board. Stop with the A.I. Support. We spend a lot of money with you and expect something in return besides the POS being down, bad apps and poor customer support.

If I could leave zero stars, I would.

The problem is not just the support; it's the app itself. I've spent weeks dealing with Marketplace Connect issues that continue to impact my business, sales channels, and ability to operate effectively. Even after extensive troubleshooting, product cleanup, variant cleanup, and countless hours of my own time, the issues remain unresolved.

What's most frustrating is that the app appears to struggle with stale data, outdated mappings, synchronization issues, and lingering references to products or variants that no longer exist. In today's technology environment, I would expect a Shopify-supported marketplace integration to have better tools for clearing old data, refreshing mappings, rebuilding catalogs, and identifying synchronization conflicts. Other platforms and applications offer these capabilities, so it's difficult to understand why Marketplace Connect continues to struggle with them.

Unfortunately, the support experience has made the situation even worse. Instead of receiving meaningful assistance, I've spent weeks being sent in circles, answering the same questions repeatedly, and receiving little to no actionable guidance. Only one support representative appeared knowledgeable and genuinely interested in helping solve the problem. Everyone else seemed focused on repeating troubleshooting steps rather than driving the case toward a resolution.

As a small business owner, this is not a minor inconvenience. I have lost valuable time, delayed marketing campaigns, delayed marketplace growth, and experienced a significant impact on my ability to generate sales. Every day these issues remain unresolved affects my business.

What is especially disappointing is that Shopify actively promotes this app and associates it with its platform. As a merchant, I expect better reliability, better escalation procedures, better communication, and better technical support. Instead, I've been left managing the problem largely on my own.

The app needs significant improvement. The support organization needs significant improvement. More importantly, merchants need real solutions, not endless loops of questions and unresolved tickets.

This app is good when it work but all of sudden it cannot connect eBay. Customer support looked at the issue 3 weeks but still cannot come up with a resolution. This is affecting the daily operation badly when something just doesn't work all of sudden and without a fast resolution. I am disappointed and 1 star is giving to the support team.
