A 100% adoption rate for online booking tools is "absolutely possible" Marcos Isaac, director corporate and distributor channel for Amadeus E-Travel, said.
Mr Isaac said company philosophy, people getting more used to using technology and IT experts providing better functionality would all push up adoption levels.
He was speaking at the conference on Automated End to End Expense Management - reality or myth? organised by the Institute of Travel Management (ITM) in London this week.
Referring to research published earlier this year by Amadeus and Cranfield University, Mr Isaac said companies with a flat structure and little hierarchy were likely to have higher adoption rates.
He also highlighted companies where management bought into online booking, where travel was mandated and which had a high level of young people as also achieving higher adoption rates.
Tony McGetrick, director of UK sales and marketing for Expedia Corporate, said that successful adoption was not just about the tool but also about the "ability of the TMC to communicate with the client."
He added: "You can't implement a self booking tool and walk away from it. It is something that has to be permanently focused upon.
"Otherwise you will see an initial peak and then a drift away from it."
Earlier Geoff Allwright, travel and expense manager for Airbus UK, told the 120 delegates how he had adopted both online tools and an end to end management system at his company over a two year period.
He said the process involved six departments and six different suppliers from KDS which supplied the tool to SAP which provided the management system.
He said a similar process had been followed in Germany, France and Spain where Airbus had plants.
The adoption rate in Germany is now more than 80%, in Spain just under 80%, and in France and the UK around 70%.
The company was also saving €5m year on year through self booking and had enjoyed a 200% return on investment in the new equipment.
