ConnectyourSquarePOStowarehouse-levelinventory.
Every Square transaction adjusts warehouse stock in real time. Nautilus bridges the gap between point-of-sale and warehouse management for retailers with physical locations.
Inventory data, where you need it.
Three things the Square integration does well — and that you'd otherwise be doing manually.
POS sync
Square POS sales instantly decrement warehouse inventory counts.
Catalog mapping
Square item catalog maps to Nautilus product database bidirectionally.
Multi-location
Manage inventory for multiple Square locations from one warehouse.
Bidirectional sync. No manual entry.
Data moves between Nautilus and Square in both directions, near-real-time.
- Inventory levels
- Reserved stock
- Location data
- Lot/serial info
- Orders
- Returns
- Product catalog
- Channel mappings
Four steps to live.
Under 10 minutes for most teams. The full health check takes longer but doesn't block sync.
Connect
Authenticate with one click. Nautilus uses OAuth — no API keys to copy, no credentials to store.
Map
Match your products, locations, and accounts. Nautilus auto-maps by SKU where possible.
Sync
Enable bidirectional sync. Changes in either system reflect in the other within 30 seconds.
Verify
Run the sync health check. Nautilus flags any mismatches before they become problems.
What the integration does, in numbers.
Quick answers.
How long does setup take?
Most customers are syncing in under 10 minutes. Enterprise environments with custom field mappings can take 30 minutes to an hour.
What if a sync fails?
Nautilus retries with exponential backoff for 24 hours. After that, the record is flagged in your dashboard for manual review. Sync failures never block your warehouse operations.
Can I limit what syncs?
Yes. Granular controls let you sync specific products, locations, or even specific fields. Most customers start with everything on and tighten over time.
Is the integration included in all plans?
This integration is included in Pro and Enterprise. Free plans can install but with limits on sync frequency.
