Merchants say this app is a reliable “set and forget” solution for syncing multiple Shopify stores across countries, channels, and POS locations. It keeps inventory, products, and collections aligned in real time, preventing overselling and saving significant time. Features like automatic product creation, price rules, and duplicate management are praised. Long-term merchants highlight stability with large catalogs, and many describe support as exceptionally fast, hands-on, and highly knowledgeable.

I am writing this review immediately after uninstalling this app. Despite following the setup guides precisely and setting my main Shopify store as the primary inventory source, the 'Multi-Store Sync Power' app instantly and inexplicably set my entire inventory quantity to zero (0) across all products and variants in my primary shop.
This was a catastrophic failure. It took me over 3 hours of manual effort to check the Inventory Adjustment History for every product and restore the stock levels. This operational loss, combined with the lost sales that occurred while my store incorrectly showed zero stock, cost my business thousands of dollars.
An app designed to simplify inventory management should never be capable of such widespread, destructive data loss on the primary source store.
I strongly caution all merchants: Do not use this app until the developer can definitively guarantee this fundamental and financially damaging bug is resolved. It is a risk not worth taking
Hi Team at Babies Mart Australia,
Thank you for reaching out and sharing the details of your experience with Multi-Store Sync Power. We understand how stressful it can be to see unexpected inventory changes, and we want to help ensure everything is fully clear and addressed.
Our team has reviewed the situation and outlined the suggested next steps in a separate email. Once we hear back from you, we’ll be ready to assist further and guide you through everything.
If you have any extra details or questions, please feel free to reply anytime — we’re here to support you in any way we can.
===== UPDATE, Nov 26th, 2025
As we were not able to connect with you through our previous messages, we wanted to share a bit more information here in case it helps.
After reviewing your case, we can confirm that the product data sync was set to use the Main store as the source. However, the inventory sync has its own separate configuration, and in this section the setting was set to Minimal. While this separation can feel confusing at first, many merchants rely on having independent controls for product data and inventory, as it gives them greater flexibility in managing different workflows.
We have also reached out to you directly via email with a clear explanation and a detailed plan to ensure a completely safe setup if you decide to give the app another try. The steps we shared are tailored specifically to your stores and use case. And please be aware that while the applications are installed, we are able to reverse the changes made by the apps if necessary.
Your feedback is extremely valuable to us, and we are already working on improving the onboarding guidance and UX to make these distinctions easier to understand for everyone.
Thank you again for taking the time to share your experience. If you would like to continue the conversation or provide any additional details, we are always here to help.
Disaster! I'm struggling for over an year with this and it never worked properly. If you're adding new stores to the existing ones, make backups, because your inventory will be ruined. Proven 2 times, even if you strictly follows their instructions
Horrific. After two years of trying, I am finally giving up on this worthless app that has NEVER worked properly. Despite numerous conversations and video calls with their OWN dev team, it STILL doesn't function correctly. I am SO happy that I found an alternative... fingers crossed this one actually delivers on its promises....
We used this app for around two years, it was always a bit glitchy and a bit slow but it generally worked. 2 weeks ago our products stopped syncing to our destination store (even though the dialogue box showed that the sync was successful). I contacted support and was met with an incredibly condescending response that we must have changed the settings (we didn't). 6 frustrating emails later, the development team conceded that they had indeed updated the software (without any notification), and the app would no longer work for us. Average product, terrible service, we've moved on.
Hi Team at Use-Ta!
Firstly, we would like to extend our sincere apologies for the inconvenience and frustration you've experienced. Thank you for taking the time to bring this to our attention; your feedback is invaluable in helping us improve.
After a thorough internal review, we recognize that we fell short in multiple areas. You were absolutely right about the inadequacies in both our communication style and the accuracy of the information provided. We understand that the recent software update blocked the manual update functionality that you were accustomed to, and for that, we are genuinely sorry.
To make amends, we are already working on an update to restore the manual sync function you relied upon. This adjustment will be rolled out in our next update. Moreover, we have conducted a comprehensive review with our support and development teams and held a 'lessons-learned' session to prevent future communication lapses.
We regret that our shortcomings have led you to move on from using our application, and we appreciate the time you spent with us. Your feedback will serve as a critical learning point for us to better our product and customer service moving forward.
Again, thank you for your honest review, and we deeply regret the inconvenience you’ve faced.
Would change my stock levels randomly. I over sold stock and it kept changing my pictures randomly
Hi team at Ecococoon,
Thank you for sharing your experience with Multi-Store Sync Power. We understand that consistent inventory and image syncing is crucial for keeping everything running smoothly -- and we want to make sure you get the reliable setup you need.
After reviewing your account, we noticed that the stores are currently disconnected, which prevents us from fully investigating the behaviour you described. We would really appreciate the opportunity to take a closer look and help ensure everything works as intended.
If you are open to giving the app another try, we would be more than happy to assist with the complete setup, walk through the sync logic together, and make sure inventory and imagery sync exactly the way you want. Our team is here to support you every step of the way.
We have also sent a follow-up email with additional details and an offer for a call with our senior team at your convenience, so we can guide the setup and ensure everything is configured accurately going forward.
We genuinely appreciate your feedback, and we would welcome the chance to help you get the most out of the app.
Warm regards,
The Egnition Team
This app erroneously put hundreds of items out of stock in my main store, when trying to sync stock levels from main store to a connected store. I had a backup but still took a long time to rectify because of orders placed in the downtime.
Hi Team at Clean Nutrition,
Thank you for your review and trial of the app. We are really sorry to hear you have experienced mentioned challenges. Upon reviewing the situation in detail, we could see all of that could have been avoided via adjustments to the configuration and minor fixes of your product data to avoid SKU duplicates. The support team has reached out a few times to discuss, however, has not heard back. Please get in touch if you need any further assistance with recovery or configuration, we will be happy to assist!
Does not work, stock has been completely messed up. Do not use. If this company can fix the app then it will be a good app. Also got spammed constantly for 'stock synched'.
Hi Team at BullyBillows,
Thank you for your review and for trying the application. We are sorry to learn that you have encountered the aforementioned difficulties. After reviewing your setup we identified that some of the SKUs have duplicates. This is something that can be addressed quickly and efficiently. Our customer service team already reached out suggesting a screen sharing session where they can walk you through the configuration and the most efficient way to address the issues with the product data. We hope to speak to you soon!
This the app hoping it would help connect my inventory between stores. My store started deleting inventory on its own. Contacted shopify support and they told me it was an issue with multi store. Multi store ended up erasing my inventory data and changing my SKU numbers, causing the store to suddenly have zero inventory in SKUs. Not sure how extensive the damage is, but we've deleted the APP and now have to go in and do a full inventory count. maybe this app is a good solution, but changing my SKU numbers and inventory count is not something i can deal with right now.
Thank you so much for trying the app and finding the time to connect. We are glad we managed to get to the bottom of it and identify the data corrections required in order to use the app. Welcome back and let us know should you need anything else :)
Don't install the app!!! Almost 2000 variants turned to negative qty and still not sure it messed up other items as well. I emailed support back and forth but they reply my email every 2 days without a solution for almost a week. Decided to just uninstall it. Now I need to fix up the whole inventory which will take me a while :(

Thank you so much for your review and apologies the communications on our side were not great. Indeed, the app requires unique SKU for each variant and speaking of one-way sync it is only possible for products & collections but not inventory. On behalf of the team, we apologize for not explaining it clearly and not providing an adequate level of support on this occasion.
