Nautilus connects to QuickBooks Online and QuickBooks Desktop. Inventory counts, cost of goods sold, and purchase orders sync both directions, so when stock moves on the floor your books reflect it without anyone touching a journal entry.
Inventory data, where you need it.
Three things the QuickBooks integration does well, that you'd otherwise be doing by hand.
COGS posts on every move
Each pick, receive, and adjustment posts to your inventory and COGS accounts the same minute. No batch jobs, no end-of-month reconciliation push.
Low-stock PO drafts
When the forecasting model flags an impending stockout, Nautilus drafts a PO in QuickBooks pre-filled with the vendor and quantities. Your buyer approves or edits before sending.
Locations map to QuickBooks sites
Each Nautilus warehouse or section maps to a specific QuickBooks Online inventory site (or Desktop class). Reports break out cleanly by location without manual filtering.
Bidirectional sync. No manual entry.
Data moves between Nautilus and QuickBooks in both directions, near-real-time.
- Stock balances
- Receipt events
- COGS entries
- Cycle count adjustments
- PO receipts
- Vendor records
- PO approvals
- Bill matches
- Item updates
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.
QuickBooks questions, answered.
Does this work with QuickBooks Desktop, or only Online?
Both. QuickBooks Online uses the official OAuth API and posts events as they happen. QuickBooks Desktop syncs through the QuickBooks Web Connector, which polls every 5 minutes; Desktop customers should keep the Web Connector instance running on a workstation that stays online during business hours.
What happens if QuickBooks is down?
Nautilus operations continue. Pending journal entries, COGS posts, and PO updates queue locally on the warehouse side. Once QuickBooks is reachable again, the queue flushes in original order. Your warehouse isn't held hostage by their availability.
How are month-end adjustments handled?
Adjustments post the moment they happen, not at month-end. A cycle count adjustment on the 17th posts the corresponding journal entry that minute. Year-end inventory valuations are accurate to the day without a separate close process.
Will this work with QuickBooks Enterprise Advanced Inventory?
Yes. Nautilus handles QuickBooks Enterprise's site, bin, and lot tracking. We translate between Nautilus's location hierarchy (warehouse → section → bay → level) and QuickBooks Enterprise's site/bin structure during setup.
