Purchase invoices are input daily by the purchase ledger clerk, who has been in the role for many years and, as an experienced team member, he does not apply any application controls over the input process. Every week the purchase day book automatically updates the purchase ledger, the purchase ledger is then posted manually to the general ledger by the purchase ledger clerk. Payments system Trinity maintains a current account and a number of saving (deposit) accounts.
