NEW YORK » Taxis are losing business travelers to ride-booking services like Uber, a survey shows. In the three months ended in June, Uber overtook taxis as the most expensed form of ground transportation, according to expense management system provider Certify. Uber accounted for 55 percent of ground transportation receipts compared with taxis at 43 percent.

That’s a big jump from just the beginning of the year. In the first quarter, Uber Technologies had 46 percent of receipts tracked by Certify compared with 53 percent for taxis. "Established travel providers will need to adapt quickly or face further market share erosion to the sharing economy," Certify CEO Robert Neveu said in a statement.

Certify based its finding on the 28 million trip receipts its North American clients submit each year. It does not include receipts from business travelers whose companies use other services to track expenses.
