syncX: Stock Inventory Sync

Stock Sync is by far the best app I’ve used for inventory synchronization on Shopify. It’s simple, reliable, and does exactly what it promises. But what really makes it stand out is the customer service — the support team is extremely polite, helpful, and always responds quickly. They’re ready to assist with any issue to make sure everything works smoothly and no difficulties arise. I truly appreciate their professionalism and dedication. Highly recommended!

The app seamlessly handles our stock updates from multiple suppliers via SFTP, direct URLs, and file uploads, saving us countless hours of manual work. The flexibility and customisation options are fantastic, and we’ve been able to automate complex inventory workflows that would otherwise require expensive bespoke development.

Support has also been reliable and responsive whenever we’ve needed assistance with more advanced configurations.

If you're managing large inventories or syncing with external systems, Stock Sync is hands down one of the best apps on the Shopify App Store. Highly recommended!

UPDATE 13-08-25 From 2 stars to 4. Read the first review further down. New Review. The after some time did reach out and they seem to be working on the issues. It does seem as if, the genuie want to help. If they succed I dont now. 4 stars for now.

Not sure what to think yet. at first glance it looks easy, but still has some issues with setup and variant SKU is missing in drop down. also when reach out to chat, its just an AI no person.

even tried some of the "solutions" provided from the AI and that did not help.

I think I might uninstall again, but maybe give one last try.

Perfect for sync stocks from other websites trought google sheets. I found a bug and contacted their suport and they fixed it within 24H as they had proimses. Everything very good and easy to use

Wow – what an awesome experience! We first tried this on the free version for our business, and honestly, it was just what we needed to begin with (FREE! ). Super easy to set up and actually useful from day one. We tested it with all kinds of uploads: one supplier sent us emails, another had a Google Sheet with about 2,000 SKUs, and we even hooked up a direct RSS feed. Every method just… worked. Simple, smooth, done! In the tech game, that is hard to get!

As our business grew, the platform grew with us. Their pricing is fair, and the customisation is next-level. We needed multiple feeds (lots of them!) but not an insane amount of SKUs (around 10,000) and only a few daily updates. It was so cool figuring out the perfect setup that fit us like a glove.

Then came the big test: we hit a super weird API challenge where we had to pull data, match it to an RSS feed, and re-map it back in. I thought, “No way they’ll sort this out for just me.” But guess what? The team actually built a custom location-based filter within a couple of days! Not only did it solve our problem, but they’re now planning to roll it out across the whole platform. That’s insane. Talk about customer-first thinking!

I don’t expect they’ll build anything for everyone, but the fact that they listened, understood, and delivered a real solution says everything about how these guys operate.

Massive shoutout to the team – brilliant to work with, innovative, and just genuinely awesome. Thanks again!

Tut genau, was es soll.
Einrichten, verbinden, fertig. Bei mir funktioniert alles reibungslos – Bestände werden zuverlässig synchronisiert. Genau das, was ich gesucht habe. Empfehlenswert!

What you should know about this app, well it is excellent it really helps someone that has no prior technical knowledge to follow guides and with a 75 - 100% rate setup his supplier's XML file. ( The rate is adjusted per the file your supplier will provide you with).
But besides that, you have a team that constantly tries to support you, edit for you and even check up on you for your ''success''.
And that is just incredible, not only as a product but as an overall service.
10/10 would recommend again and again!

Editing this (originally 1 star) review to say that the team fixed this issue and now we are able to use 3rd party fulfillment locations again!! They fixed it within 24 hours after I brought up the issue.

Original review below:

This app has been AMAZING in the past for our store, since we have multiple vendors and manage syncing inventory from multiple locations. We use a different app for order fulfillments, and now they are no longer supporting fulfillment locations from 3rd party apps. This completely bricks our process and makes the app unusable for our use case. I'm not sure why this change was made but if it's not resolved in some way we will have to switch to a different app.

Stock Sync is an essential app for any e-commerce business who needs to bulk edit! The platform is excellent and the customer service team is beyond my expectations. At Sweatfully, we have many different suppliers across different industries and Stock Sync makes adding new or updating current products a breeze. We would not have been able to get to where we are today without Stock Sync.

I believe every Shopify business should have this app. It is a no brainer to download and purchase. Pricing is very reasonable. And their customer service is the best team I have experienced, and that is us working with 30+ other Shopify App customer service teams. Save time NOW and download Stock Sync!

Tried to setup this app to sync my Square store and Shopify. Sadly they do not document this process and their support did not have any helpful information. Already requested a refund from them.
