Selling in a physical store with Square and also online often means two separate inventory counts that never match. Updating stock by hand takes time and causes mistakes. It can also lead to overselling items you no longer have or hiding items you still have. SyncPenguin fixes this by tracking every stock change in Square and in your other channels and syncing those changes automatically. Your quantities stay accurate without spreadsheets or manual updates.
How does it work?
The Square Inventory Quantities connector keeps stock levels in your Square account in sync with your other sales channels. Connect one Square location, then sync it with online stores such as Shopify, WooCommerce, Squarespace, or BigCommerce, with accounting tools such as Xero, or with other Square locations. When you make a sale in your shop or online, SyncPenguin applies the stock change everywhere else. Each product appears in stock only when you actually have it.
What can Square inventory quantities be synced with?
Popular real-world use cases
- Keep stock aligned between two Square locations, for example a main shop and a second store that share the same product catalog.
Key features
Near Real-Time
Square notifies SyncPenguin as soon as something changes, so stock updates reach your other channels within moments.
SKU or Barcode
Match products across systems by SKU or by barcode (UPC), whichever your channels have in common.
Location Based
Pick the Square location to sync. You can even keep stock aligned between different Square locations.
Smart Adjustments
Sales and restocks are applied as adjustments to current stock, so simultaneous sales on different channels are all counted correctly.
Selective Sync
Limit syncing to a chosen list of SKUs or barcodes and leave other products untouched.
Affordable & Scalable
With SyncPenguin you only pay for actual changes to your inventory quantities, regardless of how many products you initially have, or will have in the future.
Things to note
- Each connection syncs one Square location. To sync several locations, add a separate connection for each one.
- SyncPenguin only updates stock quantities. Products must already exist in Square with a SKU or barcode, and product details such as names, prices, and images are not synced.
- Each SKU or barcode must be unique in Square. Items with missing or duplicate SKUs or barcodes are skipped to avoid updating the wrong product.
- Only in-stock quantities are synced, in whole units. Inventory tracking should be turned on in Square for the items you want to sync.
