The clerk, using a laptop computer, then posts to the digital employee records. The clerk then mails the cheque to the employee and files a copy of the cheque in the department. Finally the clerk prints two payroll summaries from his computer. He sends one of these to the AP department and the other to the general ledger department. The AP clerk receives the payroll summary, approves it, and writes a cheque to cover the entire payroll. The clerk then sends the cheque to the bank where it is deposited into the payroll imprest account. The general ledger clerk receives the payroll summary and posts to the related accounts in the digital general ledger, using the department PC. Fixed Asset Procedures User in individual departments verbally report their fixed asset requirements to their respective managers. If the request is approved, the manager manually prepares a fixed asset request form and submits it to the purchasing department. Upon receipt of the fixed asset request form, the purchasing department clerk manually prepares two copies of a purchases order. The clerk sends one copy to the supplier and files one in the purchasing department. Finally, the purchasing department clerk manually prepares a hard-copy fixed asset change report and sends it to the fixed asset department. When fixed asset are received, the receiving clerk reconciles the goods with the packing slip and invoice and then manually prepares a receiving report. The clerk sends the goods to the user department and forwards the packing slip, invoice, and receiving report to the AP department. The AP clerk reconciles the documents from receiving, manually writes a cheque to the supplier, and manually prepares a journal voucher, which she subsequently sends to the general ledger department. The general ledger clerk posts journal vouchers to the digital general ledger using the department PC.
