Connect Square POS and Etsy for Streamlined Sales
Many sellers using Square POS and Etsy still manage inventory manually. Products are created separately in Square and Etsy. Stock is adjusted after each in-store sale in Square, while Etsy stocks are updated later. Orders are reviewed one by one to prevent overselling.
This approach may work when order volume is low. As Square in-store sales and Etsy orders increase, it becomes risky. Inventory levels fall out of sync, variants don’t match, and sellers oversell items that are no longer available.
With QuickSync’s Square and Etsy integration, inventory updates automatically after every sale, online or in-store. No more guessing stock levels, manual adjustments, or overselling—just accurate inventory everywhere.




Real-time Inventory Sync
Inventory syncs in real-time after every Square POS or Etsy sale. This prevents overselling and stock mismatches.

Orders Sync
All Etsy orders sync directly into your Square dashboard. Manage fulfillment and order processing alongside in-store POS transactions from one centralized system.

Products & Listings Sync
Product titles, descriptions, and images sync between Square and Etsy. Update a product once, and it reflects everywhere.

Variants & Media Sync
Variants such as size, color, or material, and Media sync correctly. QuickSync handles Etsy’s option limits and maps Square variants cleanly.

Pricing Sync
Prices stay consistent across the Square and Etsy shop. Price changes apply automatically to both stores without manual edits.

Square as Fulfilment Store

Probably the best support I’ve ever received from an app. Joseph went above and beyond to answer questions and provide documentation I needed to confirm what was syncing between the app and my store. Great follow through and super friendly. Thank you!
