I needed this app for a transition from Square to Shopify. This is the absolute worst app for this task. Half the time SkuHarmony won't open and the other half of the time it takes a half hour to load just to end up crashing. I do not recommend.

This app is pretty bad. I spent days setting up SKUs and entering inventory. Signed up for the auto sync at $50 a month. It’d be worth that if it worked. Shopify orders aren’t decreasing inventory in Square and Square sales aren’t decreasing inventory in Shopify, except one in about 10 inventory changes (an order for 4 products correctly changed inventory for only one of them). Inventory is randomly being changed for one product with no activity to tel it to do so. I am sad, if this app worked well enough, it’d be great. It’s unusable.

We apologize for any issues you experienced when syncing inventory. Please contact support to have your specific account looked into so we can better understand what may have happened.


SkuHarmony's customer service is horrible! After deleting the Skuharmony's App, due to its poor performance and the hardships I suffered due to the economic crisis from covid-19, I still got charged. I reached out to Shopify a few days later when the funds came out of my account. Shopify was helpful and understanding. They reached out to SkuHarmony for a much needed refund. This is the response I got from Dustin at SkuHarmony, "I authorize a refund for the SkuHarmony application if it was not performing to the user's expectations, but to request a refund "due to current situation with covid needs the funds back for the subscription" is a bit out of the ordinary. I don't run a charity. Do they have a better reason for requesting a refund?". I am completely turned off by Dustin's reply, simply hurtful. Do we need a better reason than Covid-19 and a pandemic? Unbelievable.

Every time I add inventory to Square, the numbers in Shopify get screwed up. It often goes rogue, altering inventory numbers when no transactions have taken place to change numbers. Auto-sync works sporadically. Heading into the holiday season, I really need to trust the sync between Square and Shopify but cannot with SkuHarmony.

We apologize for any delays in support during late September. We had changed settings in our customer support management system and didn't realize we were filtering some messages incorrectly. This is now resolved.

It worked great for almost a year, then they updated the app supposedly. The customer service was really lacking. The person I spoke with was very cavalier. (As if it did not mater that my inventories were not synced daily from my POS to my website.) Now, it does not work at all! I went to remove the app to try and reinstall it. The plan I was using is no longer available. But they do have a plan that no costs $49/month. Hmmmm! I think I see where the problem is... Its all about trying to make more money than they were. Will not ever recommend this app.

Thank you for your review; and I apologize for your poor experience. To resolve this, please disable automatic syncing and manually reconcile the inventory quantities using Shopify and Square. Then, manually sync your inventories to ensure everything pulls into SkuHarmony correctly. Then you can re-enable automatic syncing to continue keeping your inventory in sync.

SkuHarmony is free to manually clone and sync your inventory, and $49 monthly to automate the inventory quantity syncing. No changes have been made in pricing.

It worked for a few months then stopped working. The new support guy told me that my account had been disabled because I had 5,000 items in Square and their new limit is 2,500.

I do apologize for the limitation. However, this limitation is in place to maintain consistency and accuracy of the syncing process. Beyond 2,500 SKUs, Square and Shopify APIs can time out, giving inconsistent and sometimes incomplete inventory results, causing all sorts of havoc with your inventory.

We expect to support much larger SKU counts in a future update once we refactor some of the original code base.

Excellent app, It fits my stores needs very well. We use square in our Brick and mortar store but we had a hard time syncing our inventory with shopify but once we started using SkuHarmony keeping our shopify and Square inventory in sync was so much easier. I even use the app to add new product to my square store. Uploading the product to both at the same time makes my life alill less stressful. :)

Note: It would be nice if you could search in the square inventory tab for specific items i want to add to shopify store, instead of scrolling through my entire square inventory till i find want in looking for. Also when transferring into square it adds the new items without tax. Then i have to manually go into square dashboard and product to add tax to every new item.

That being said its a great app that tremendously helps my business flow more easily. The draw backs are small compared to tremendous gain this app provides. :)

A little slow start but once I received help from the app designer things got better. I love how I can sync my shopify store with square perfect for a summer pop up shop I am attending in a few weeks.


This app really helped us streamline our operations. We used it to copy all of our products from Shopify to Square and then enabled auto-sync. Perfection!
