For years the growth in the use of electronic invoicing was hampered by a very simple fact. There was nothing in it for suppliers.
Think about it. A supplier wants to be paid and needs to send an invoice. Whether that’s a paper invoice in an envelope with a stamp on it or an email makes very little difference. The cost of a stamp has got nothing to do with it – unless a supplier is sending many very low value invoices, the postage cost is trivial. While only a few customers demand electronic invoicing, while the business world was largely paper based and while suppliers were being asked to subsidize the cost of their customers' e-invoicing programs by paying for the privilege of sending an invoice, there was always going to resistance.
But the world has now changed and the business case for e-invoicing is now fundamentally different to the one-sided calculation with all the benefits loaded on the customer side that would have been built perhaps 5 years ago.
