Scored on 17 merchant reviews we hold for SkuHarmony, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 17 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

if you are looking for an app to connect the inventory of shopify with Square, this is the app to use. We have had excellent results and the support from SkuHarmony has been above and beyond what I had expected.

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.

I use Square at events and in my boutique, and Shopify on my e-commerce website but all of the above draw from the same inventory source (which I keep at my shop). Squarify allows me to keep stock counts in sync between Square and Shopify, which is essential! Thanks for a great app!

I don't think I've EVER received BETTER customer service then I have from Squarify! The creator is very passionate about his app and making sure it's fitting our needs and working exactly the way it should. On multiple occasions, Squarify customer service has gone out of their way to make sure we're up and running successfully. Super THANKFUL for Squarify!

This app has honestly saved me from pulling my hair out over inventory syncing and discrepancies. Running a small business is definitely a challenge, especially when running it across two platforms. Squarify has helped me sync up and keep track of our entire inventory, ensuring that everything online + in store is live and accurate. Not only is it an easier interface that other syncing app's I've tried, but their custom service is reliable and dedicated. With any issue or confusion, they've been quick to respond and answer all my questions–and they follow-up as well to make sure everything ended up a-okay. Seriously cannot thank or recommend Squarify enough!!!

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.

Developer repliedThank 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. Show more

I am two days into using this app and I am sold! I had to work with Chad a few times on my integration, but he is very responsive and wonderful to work with. Inventory control has been nonexistent in my business up until this point and I am so happy that I have control of it now. It is a big relief and I feel confident that Squarify has taken the frenzied mess I had and created a smooth streamlined transition. I look forward to many years of positive inventory control with Squarify!

We LOVE this app! We searched for a long time to find the solution to using Shopify for our online store and Square in our Brick and Mortar. We really didn't want to stop using Square. Squarify saved us! It is really easy to use and navigate. It is quick to update everything and shows very clearly what needs to be updated. Being able to review any discrepancies in one place is a great time saver and ensures accuracy!
