Double entry accounting system was invented in 15th century and still being in use until today, this is quite an interesting fact; however it indicates that there is something about the system, thus making it so effective and irreplaceable. To evaluate the effectiveness of the controls in the double entry system, we should first question ourselves why is double entry book keeping system is still being used until today. Double entry book keeping is very useful because it can help spotting a lot of errors that accountants make every day. The fact of the matter is, that every transaction is being entered twice, which can eliminate some of the errors, that otherwise could have been missed out. For example, an accountant has debited £1409 P.Vasiljev’s account instead of £1490, however because he had to credit the bank account as well, he looked at the transaction again, and spotted the error. Furthermore this system helps us to find errors using trial balance. As the trial balance will eventually be produced, it will identify whether or not, total of debit will equal to credit, if not, it indicates that errors has been made. Despite the fact, there are errors that double entry accounting will be unable to reveal, which will be shown below. (http://www.canhamrogers.com, 2011)
