Over the years, many solution providers have tried to explain e-invoicing, both textually and graphically. Here is a very effective explanation from OB10.

The flash presentation explains the problem, how OB10 solution works and the benefits it brings. Accountis pulled out from their website a similar flash presentation when they launched their new website. In my opinion, this was a mistake.
I would like to request OB10 to upload this video to Youtube. This will not only add another item to existing two videos on youtube, but will further help clarifying why e-invoicing is sexy! and a must have tool for medium to large organisations worldwide.
