MY GEM CLOSET review for Etsy Integration by QuickSync

Dec. 10, 2025

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.
