SOUTH PORTLAND, MAINE -- Fleet card services provider Wright Express has enhanced its Internet-based account management tools with an online payment feature that eliminates the cost of cutting and mailing a check, the company said Wednesday in a statement. The new payment feature on WexOnline provides fleet managers a higher degree of integration between invoice, payment, account maintenance and other functions, the company said. Online payment will be available to the company's private label and cobrand partners as well as fleets using its Wright Express Universal Card.
