Stock Sync has made it simple to import and export products with our East Village vendor and retail partners - highly recommended!


Incredible! I was looking for something like this over years... Stock Sync saved my neck in a very important stage of my online store, where the sales were going up, but I wasn't able to keep up. There are many features that will help you connect with all your suppliers in a wide range of methods: from a single csv file to a database connection with another shopify store! One feature I enjoyed and I can't find it anymore is the ability to download three kind of update reports present in the feed activity log: "failed product", "store unmatch" and "updated info". They were VERY useful to detect problems, give some comfort and security about the update process. For the developers: future updates could consider a new feed method for updating products: XML "queries". Right now, you can only add ONE single XML file, but could be more useful (at least for me) you could specify several URLs where each one works like a XML query. Actually, we have a provider working like this, and right now we download each XML "query" in separate files, combine them with Excel and then upload the file. Thank you for the amazing work you're doing!

My experience has been horrible! I couldn't understand their instructions to add any feeds or make any adjustments so their support team did it for me. Then, I had to update my feeds after I found out they hadn't been working for 2 months due to the fact I was supposedly on a trial period, but I didn't receive any notifications to let me know! Once I paid for the level of service I needed, which was confusing so I was charged 4 times in a matter of hours, but they said I had to contact Shopify for that...Anyway, I ran the feeds to update only to realize that one of the feeds was set up as Cost/Quantity, which ERASED ALL OF MY RETAIL PRICES on my products and changed them to Wholesale. So, of course, I lost revenue since customers bought the items at wholesale! I notified, their support team, which takes about half a day to answer or longer, so it's not within a couple of hours as advertised! They said they fixed it, but upon checking, no they didn't...So now, I'm still waiting for them to fix it back to the correct retail price..... In the meantime, all those products had to be removed from my website. This is not like other Apps where you just answer the questions: What is your mark-up? You input the number and it's done. With this app you need to have more experience with coding or it will frustrate you! However, their support team set everything up for me, but the sad thing is the end result was NOT what it should have been! I don't recommend it and the only reason I'm not removing it at this time is because one of my current vendors uses it and nothing else, so I'm stuck until I decide to part ways with my vendor. They get 2 stars for their support team! Update: 12/5/20...They fixed the issue after a few more tries and my feeds are now working properly. I have also reloaded all my products after several hours of work, lost revenue, and clients. They have asked me a couple of times to update the 2 Stars I gave them on my review due to the fact they finally fixed the issue as they have been in business for 5 years with 5 stars and their team's current low morale as they want to end the year on a positive note..... While I can understand how my review may impact them, if I change the stars and my review that would be deceptive and not a true reflection of my experience with them. Additionally, their request is offensive due to their lack of consideration to the impact it had on my business and my team's morale. We had to spend many unnecessary hours to reload all our products and double check pricing in addition to what I already captured in my review. Everyone's experience is different, but this was mine.
