This app connects to your odometer to clock and identify trip miles. All miles are automatically tracked in a “Trace Trip Journal” accessible from your mobile phone. You simply swipe your phone to send business trip miles right into SAP Concur®, and your mileage expense is ready for submission.

“Trace” was originally developed with Concur APIs and Ford APIs at the Ford Hackathon in 2014. Companies like Automatic and MileIQ have taken the concept even further by integrating with hardware that connects to the diagnostic port in any vehicle manufactured after 1996.
“Personal Car” expenses can average $123.09 per traveler.* We wanted to make it easier to pull mileage right from your dashboard into SAP Concur®.
