"David Cameron is talking a lot at the moment about how he can make the government more efficient, about how it can work better with suppliers - well, pick a solution that doesn't cost suppliers money and helps them get paid faster. I think there's a tremendous opportunity here."
When asked if he thought the UK government could save a similar amount to the Danish government, Lanng responded by saying: "Absolutely, if not more".
"Of course I would love it if everyone used Tradeshift, but that doesn't have to be the case. What we really advocate is government's using open standards, so that everybody can participate," said Lanng.
"This is what we did in Denmark and it created an explosion of companies adopting it. I think it's the government's job to ensure that everyone can do business with the government."
He added: "It's very important that the government picks solutions that are open, free for suppliers to use, and don't lock people in."
