Automate Your Accounting Workflow
We’re excited to announce a brand new integration between FL3XX and QuickBooks Online, one of the world’s most trusted financial management platforms.
This powerful connection brings your flight operations and your financials closer together - cutting out double data entry, reducing errors, and giving you full confidence that your accounting is always in sync.
The FL3XX - QuickBooks integration makes financial management easier than ever. Operators can now:
- 
Automatically sync customers, products, and invoices between FL3XX and QuickBooks 
- 
Create invoices instantly in QuickBooks the moment they’re sent from FL3XX 
- 
Map FL3XX line items to QuickBooks Products/Services for accurate reporting 
- 
Customize invoice structures, including simplified or aggregated line items 
- 
Maintain data accuracy with a secure OAuth2 connection 
No more manual copying or re-entry: your invoices flow directly from FL3XX to QuickBooks, complete with mapped line items, calculated taxes, and synchronized customers.
Built for Aviation, Not Just Accounting
Aviation accounting isn’t like any other industry - and FL3XX continues to be built with that in mind. This exciting new integration ensures that your aviation-specific tax calculations (like FET, VAT, or passenger-based taxes) are handled within FL3XX before syncing, so QuickBooks always receives accurate totals.
That means no more reconciling mismatched tax lines or manually adjusting figures after import. Everything stays precise and consistent between both systems.
Flexible Configuration, Easy Control
Once connected under Settings → Integrations → QuickBooks, you’re in full control of how data flows between platforms.
You can:
- 
Enable or disable specific sync features 
- 
Link FL3XX accounts with QuickBooks customers automatically or manually 
- 
Choose how incremental invoices are handled - individually or as a single aggregated update 
- 
Adjust default payment terms and due dates directly in FL3XX 
Everything is designed to work seamlessly out of the box, but with the flexibility to match your organization’s accounting preferences.
Why QuickBooks?
Intuit QuickBooks is one of the most widely used financial management systems worldwide, simplifying invoicing, expense tracking, and financial reporting for millions of businesses. By connecting QuickBooks with FL3XX, operators can now bring those same efficiencies to their aviation back office - without disrupting established workflows.
