For me this is one of the fundamentals of running a finance department, be it a small, medium or large size organisation.

Getting things right first time, believing and having trust in the figures /outcome and fraud has the 'tag' of internal control attached to it.

A very good example of internal control to prevent fraud in the era of working from home during the pandemic is receiving a purported email from your superiors to pay someone unfamiliar without an invoice in existence and being signed off and input into the system. At once if the proper internal control is implemented, one can tell that the email is a SPAM and not such payment is required.

I find myself in a different generation that requires internal control to keep me surviving. People these days are "smart". Controls are key indicators.

For haulage and other transport businesses you may even need trackers as another eye. It's costly but necessary.

Start with selecting the processes that address the 4 reasons listed in this article.
