There is a difficulty in building a business case for e-invoicing. The natural starting point is a traditional paper process and there is an irresistible temptation to begin to count the savings offered by the counting the cost of paper. A sheet of A4,  an envelope and a stamp. Well it's a starting point I suppose. And then there's the general efficiency saving because it's quicker and easier to deal with electronic invoices compared to paper. This is true of course but having 7 hours of work to do per day instead of 8 doesn't save anything. It just makes like easier. The fact is, if you approach electronic invoicing from the point of view of simply automating a paper process, then it won't save you a penny. So how do you go about building an effective business case for e-invoicing?
