electronic invoicing prayers. In fact one company which I won’t name, which claims to be a leader in 
e-invoicing, is  actively promoting it as their strategy. There are several reasons why  invoice scanning is not the answer and represents only an interim  solution.
The  holy grail in the world of e-invoicing is that an invoice should go  from creation, to delivery, to approval, to payment without a piece of  paper being created. In other words machine to machine with software  doing the work along the way. Not a pipe dream at all. Today we deliver  hundreds of thousands of true electronic invoices a year that follow  exactly this path. And with some ground-breaking new interfaces and  tools currently in testing, we expect that number to increase sharply in the months ahead.
Invoice  scanning and OCR (in the context of invoice processing) became popular  because companies couldn’t persuade enough of their suppliers to adopt a  truly electronic method of submitting invoices. This meant they found  themselves in no man’s land – paying for an e-invoice solution but still  having to retain a small army of employees to handle paper invoices.  Scanning and OCR takes the paper, scans it and uses OCR technology to  lift the data off the page so that it is useful and uses it to create an  electronic invoice. But here is why it is no more than an interim  solution:
- It is at best an inaccurate process. OCR software vendors will tell you  they can read characters from paper with 99% accuracy. That may be so  with a simple text document in a medium sized typeface. But when it  comes to small print on invoices, the reality is that it is a lot less  accurate. It only needs to read one character incorrectly in the wrong  place for the invoice to fail in an electronic approval process. Someone  has to manage these failures and exceptions. People involved in the  process? Not what was promised from “electronic invoicing”.
 
 
- OCR on its own is not enough. The next thing a well run AP department will want to do is validate an invoice before it goes into an approval process so that it doesn’t get lost within  the approval process. Validation, which is an automated  process, includes all those pre-flight checks before starting an  electronic approval process – is there a Purchasde Order (PO) number?  Does it relate to an existing PO? Is there a supplier reference? Is  there a VAT number? Does the invoice add up correctly? And so on. Even  the most sophisticated solutions with people checking every invoice  struggle with this. Suddenly the failure rate has risen. More  inaccuracies and exceptions to manage. More people involved.
 
Of  course the net result of this is that you or your outsourced provider  has to incur some real costs to bring this error rate down. Guess who  ends up getting stuck with those costs? So suddenly your business plan  doesn’t look so good. Where you were expecting to drive the cost of  processing each invoice down below £1, human intervention has resulted  in costs being much higher.
Scanning  and OCR has its place. Even allowing for the absurdity of taking an  electronic file, printing it out on paper as an invoice, sending the  paper to your customer for them to use an expensive process to turn it  back into an electronic file – it has its place. But only if you build  your business case based on there being a concerted effort to migrate  from scanning and OCR to real electronic invoicing. You should aim over a  three year period to turn a ratio of 80% scanned and 20% electronic on  its head and have 80% submitted electronically. This is all about being  good at persuading your suppliers to send you 
electronic invoices or 
online invoices. That is a whole subject on its own!
To see how a good e-invoicing deployment works 
download a case study here which  shows how Essex County Council released 20 AP staff and will save £2.5  million next year by understanding the important distinction between  scanning as a means to an end versus scanning as the answer. They now  process tens of thousands of real electronic invoices – those that go  from creation to delivery, to approval to payment without a piece of  paper being created. Invoice scanning was merely a stepping stone which  helped them to get there.
