Shopify Marketplace Connect

I tried using Marketplace Connect as a cost-saving alternative after previously relying on a custom API. Still, it has not been a solution for my most important need, connecting with the Target+ marketplace. After a year and a half of effort, there has been virtually no progress, and neither the app’s support team nor Target’s support seems to fully understand how to resolve the issues. It has been a genuinely frustrating experience. The app does work well with Walmart, eBay, and Etsy, but if your primary goal is seamless Target integration, this is not the tool for you. Save yourself the time and avoid the disappointment.

If you have a large catalog, try another solution.

There is no way to report items in stock that are not listed on ebay.

You could tag items as not on ebay and remove the tags one at a time when listed, but that's cumbersome and native Shopify reports can't report tagged inventory by location.

eBay works fully as expected.
Etsy is totally broken. Sometimes it doesn’t sync at all, new products can’t be published, and we have to write to support so they publish them manually. Sometimes the description synchronization fails. Variant images are not switchable on the Etsy side.
Category mapping isn't work also and after 6 month no fix!

Etsy is a constant pain. We have exchanged over 80 emails with support. Support does respond and tries to fix things, which is why I give 2 stars and not one.
But offering Etsy as a feature when it hasn’t worked properly for about 6 months or keeps breaking is not fair.

Works well generally BUT auto list items on eBay that are in draft or out of stock on my Shopify store. Please fix this issue….

This tool is currently broken with Etsy. Etsy now requires a readiness state identifier - whether your product is ready to ship or is made to order - and Marketplace Connect has no function for setting this value, so and new listings fail to post to Etsy. Support only answers that the merchant should contact Etsy, while Etsy says their API allows for this identifier to be passed and the app developer needs to update their code. I am stuck in a loop of 2 support teams passing the issue back to the other.

Etsy is not working, lost many sales and no customer support to fix. Etsy has said its an app issue with Shopify & Shopify says its an Etsy issue. No one is fixing the issue and both are blaming each other with no solutions offered.

Very buggy and doesn't follow the listing settings. Support are far from helpful.

I find this app to be more and more difficult to use. The settings for Amazon and Walmart are different (and probably other channels too), confusing interface and support takes all day to respond, and much of the time they are not helpful in solving issues.
If you just need a cheap way to sync inventory and download orders from your Amazon store, then this can be it. Otherwise it's a no go for me.

Their Support has become significantly worse recently, specifically "Adrian" who has repeatedly given incorrect advice which reads like it's coming from ChatGPT...

It's not as good as you first think. If you decide to change or edit anything on eBay, like price or description, you will find that all edits will be lost as market marketplace connect overwrites them back to the original settings, deleting all your edits. The only option is to edit via Marketplace Connect, but this is complex and unintuitive. Why on earth can't they have a simple selection to stop Place Connect from making future edits? I will be looking into this more, BUT unfortunately, I will have to remove this app if it doesn't offer this one simple fix. For your sanity, i would be best to avoid
