Every sale on your Shopify store decrements warehouse stock the moment the order is placed. Nautilus prevents overselling across all Shopify channels (online store, POS, Markets, B2B) and routes orders into pick workflows automatically.
Inventory data, where you need it.
Three things the Shopify integration does well, that you'd otherwise be doing by hand.
Real-time stock sync
Shopify inventory levels reflect warehouse scans within seconds, end-to-end.
Multi-location aware
Each Nautilus warehouse maps to a Shopify location. The Shopify checkout assigns orders to the correct location based on customer address, and Nautilus picks from the right warehouse.
Fulfillment automation
Picked orders flow into Shopify fulfillments automatically. Tracking numbers post back to the order, customers get the standard Shopify notification email, and the order status closes.
Bidirectional sync. No manual entry.
Data moves between Nautilus and Shopify in both directions, near-real-time.
- Stock levels
- Reserved quantities
- Location data
- Tracking numbers
- Fulfillment completions
- Orders
- Customer records
- Product catalog
- Variants and options
- Location settings
Four steps to live.
The same four steps whichever platform you connect.
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
Turn sync on. Changes made in either system carry over to the other automatically.
Verify
Run the sync health check. Nautilus flags any mismatches before they become problems.
What the integration does, in numbers.
Shopify questions, answered.
Yes. Nautilus uses the same Admin REST API and webhooks for Shopify and Shopify Plus. Plus customers benefit from higher rate limits and more flexible webhook configuration, but the integration itself is identical.
Shopify can take time to propagate inventory changes across regions. Nautilus tracks the canonical state internally and reconciles against Shopify's view every 30 seconds. If a sale beats a sync, the oversell-prevention rule blocks the second sale of the last unit.
Yes, with one recommendation: pre-warm before the sale. For a very large flash sale, a 24-hour pre-sale stock freeze where Nautilus locks the inventory level and we coordinate the burst load is best. Smaller flashes need no pre-coordination.
Multi-currency is supported. Nautilus stores cost basis in your warehouse's base currency. Shopify Markets sells in local currency; Nautilus syncs the canonical inventory level, not the price. Pricing stays in Shopify's hands.
