Following our focus on "How to avoid the cost of employee fraud" last year, Stuart Evans of Rawlison Butler LLP examines the useful feedback we have had on readers' own experiences.

The message we have been getting from people's experiences of fraud is that one of a company's own employees has often been involved to some degree. Whilst that may be right in many instances, it is not uncommon for third parties (not necessarily suppliers) to indulge in fraudulent activity without the assistance of employees on the inside; identity theft and computer hacking would be examples of this.

It is clear then that in addition to the importance of proper recruitment procedures in wheedling out the fraudster at the first opportunity, there do also need to be effective controls in place to prevent fraud once an employee has been appointed. The experience of one reader is that a typical fraudster can often be on their best behaviour to start with, in order to engender trust in an organisation. Indeed, statistics suggest that such fraudsters have usually been in a post for about 7 years before committing a fraud, which may come as a surprise to many.

It is therefore vital to ensure that the business is properly controlled, particularly to deal with operations once they have become the preserve of a trusted, long serving employee. Contrary to what many might think, fraudsters are often patient and ready to act only once the coast looks to be clear, so be warned; the phrase "I've known them for years and never thought they would be capable of this" should always be at the back of an employer's mind.

There is much to be said for reviewing your systems as a fraud prevention exercise, with outside help, rather than waiting to call for such help once disaster has struck. The costs of such a review will be money well spent if it stops a large hole appearing in your balance sheet.
