Sales ordering, goods dispatched and invoicing

Fraud

During the year, a material fraud was uncovered. It involved cash$/$cheque receipts from customers being diverted into employee$$s personal accounts. In order to cover up the fraud, receipts from subsequent unrelated customers would then be recorded against the earlier outstanding receivable balances and this cycle of fraud would continue.

The fraud occurred because two members of staff $$who were related$$ colluded. One processed cash receipt and prepared the weekly bank reconciliation; the other employee recorded customer receipts in the sales ledger. An unrelated sales ledger clerk was supposed to send out monthly customer statements but this was not performed. The bank reconciliations each has a small unreconciled amount but no$-$one reviewed the bank reconciliations after they were prepared. The fraud was only uncovered when the two employees went on holiday at the same time and it was discovered that cash receipts from different customers were being applied to older receivable balances to hide the earlier sums stolen.
