Etsy Integration by QuickSync

The UX-UI of this application is not the best, and the back-end responsible for syncing your products is spotty at best in frequent cases. It will work some of the time, half work other times, and sometimes just not work. Telling me the product is working then wanting me to provide more data for their product to try to fix it again, and again, etc...
Support and developers seem to have little insight into what is going on. Avoid unless you have no other options.

As a VIP customer, this was one of the most disappointing experiences I've had with an Etsy integration app.

I honestly found myself asking:

"Are all the other 5-star reviewers seeing something I'm not, or was my experience completely different?"

Before the migration, I spent a great deal of time preparing my Shopify store. I even sent two pages of detailed instructions to the support representative, Joseph. My request was very clear:

Synchronize only a few products first so I can review everything before importing the entire catalog.

Unfortunately, this request was ignored.

Within about a minute, the app synchronized my products from Shopify to Etsy, and many listings were transferred with serious errors. Instead of receiving the careful onboarding I expected as a VIP customer, I had to spend hours correcting listings one by one myself.

The outcome was devastating.

Only one week after using QuickSync, my Etsy shop was suspended.

I cannot state with certainty that QuickSync alone caused the suspension, but I trusted an Etsy integration app to transfer my listings correctly. If there were compatibility or policy risks, I expected them to be identified during the onboarding process—not after my shop had already been affected.

This experience cost me a significant amount of time, unnecessary stress, and the loss of my newly opened Etsy shop.

Unfortunately, based on my experience, I cannot recommend this app.

too complicated to import. made me scared and did not want to risk it. once installed it already changed how my incoming orders looked on shopify which seemed weird. scaryyyyyy

Be cautious of the 5 star reviews, while the custom service is great, they also try to have you leave reviews. The app consistanly fails, only way I can actually have listings linked is by talking to customer service and I still need to manually update listings if something sold on one platform or another.

This app is continously destroying our business, in the most crucial moments it stops to work and we need to wait assistance for hours and sometimes days while our webshop is being destroyed.

DO NOT USE THIS APP! Beware, we used this app for many months, and it will be great until on day this app will brick your entire etsy store. Support has been entirely useless. I have lost thousands of dollars in revenue because the plugin changed all of my products prices to $1 and sold out of all inventory on my stock. Support is absolutely useless, and they will not help you at all as your store burns to the ground caused by their horrible plugin.

BUYER BEWARE!

This has been a nightmare.

Listing Titles, Descriptions (Bullet Points) and Images all needed repair.

Your so-called “Fetching” erased a significant portion of my 7 year old Shopify SKUs. It will take weeks to repair.

I didn’t think it possible for QuickSync to destroy BOTH my Etsy Store and my Shopify Store.

Your “Order Syncing” is nonexistent without contact information, billing and shipping addresses. A non-starter.

One Customer Service Rep was so rude and unhelpful, he would not last a day in my employ.
(I think you can figure out who this is by reading the entirety of the 5 day thread of issues).

QuickSync’s performance would be laughable if it weren’t so sad.

I will reach out to Shopify to let them know my experience.

This app duplicated HUNDREDS of Etsy listings from my Shopify store, auto put them as active, and cost me so much in listing fees. 0/10 this app shouldn't be allowed on the Shopify app store

Unreliable syncing, ongoing data corruption, financial loss — and now blame-shifting
We installed QuickSync to connect Etsy and Shopify, hoping for a reliable syncing solution. Instead, we experienced repeated data issues over several months, including:
Inventory syncing failures from October onward
Incorrect stock levels showing on Shopify
Multiple Etsy listings being merged into a single Shopify listing
Duplicate SKUs generated by the app
Etsy titles, photos, prices, and listing data overwritten without permission
A US$240 financial loss due to incorrect price syncing
Repeated “sync successful” emails when nothing had been fixed
We reached out to support dozens of times, and each time we were told “everything is fixed,” even though the same problems continued. We gave the developer multiple opportunities to resolve the issue, including escalations to their senior technical team.
The most concerning part came recently:
Instead of taking responsibility for the errors, the support team attempted to pin the blame on us, claiming manual edits and duplicate SKUs — even though:
We never assign SKUs (QuickSync generates them)
Our titles and prices were correct before QuickSync overwrote them
Our manual edits were made after the incident to repair the damage their system caused
Shifting responsibility onto users rather than acknowledging system errors is deeply unprofessional and unsafe for merchants who rely on accurate inventory and data integrity.
We have now been forced to close our Shopify store temporarily to prevent further customer impact while we clean up the damage.
Use this app with extreme caution if your business relies on correct inventory, pricing, and listing integrity.

This app is supposed to link your etsy to shopify for fulfillment and you cannot fulfill your orders on shopify with it.

I just spent an entire week transferring over 400+ products using the app just to find out it can't transfer shipping information to shopify. Which means it does not allow you to fulfill the etsy orders once they roll through.

I am wildly disappointed and frustrated. I will be removing it from my shop and finding something that actually works.
