Ross has been working as joint interim CEO and chief financial officer of the freight management services provider.
The UK and Central and Eastern Europe-focused group said the board will shortly begin the search for a new permanent CFO.

He is comfortable with leadership and has excellent knowledge and experience of the transport and logistics markets in which we operate.
"So after a thorough process involving both internal and external candidates, we are very pleased to be able to appoint Robert and we look forward to supporting him in the next phases of the company's development."
