Track your trips, scan receipts, log mileage, and send professional invoices to your clients — all from one place. Scan Receipts with AI Snap a photo or upload a PDF and CrewRoo automatically extracts the vendor, amount, date, and category. Review, approve, and attach receipts to the right trip or expense report. Trip Tracking Log trips with tail numbers, flight legs, departure and arrival airports, daily rates, and RON (remain overnight) dates and locations.
