There are still plenty of savings opportunities when it comes to spend on business travel.
Writing in the latest Business Travel Supplement, out with today's issue of Supply Management magazine, expert business travel writer Amon Cohen suggests buyers examine opportunities in expense receipt auditing and foreign exchange.
"Air and hotel are the big-ticket items in any travel programme, but buyers who focus exclusively on those two sub-categories could be missing a trick elsewhere," he said.
In the article, expense auditing company Meridian says it queries 20 to 35 per cent of reports it processes, and says it saved ?52 (£45) in direct savings per expense claim in the first year of a contract with one client.
In the case of foreign exchange, most travellers use ATMs or an airport bureau de change which can be more costly than establishing a corporate deal on the purchase of foreign money.

In the same supplement, Cohen examines how setting up a pre-trip approvals process can achieve savings by curbing unnecessary travel. He also looks at how purchasers can make efficiencies in a category where prices remain high - car hire.
