The accounts payable system will contain a number of programs, including Enter Invoices and Print Payable Checks. For each program, describe its purpose and outline application control considerations

What will be an ideal response?

1. Enter Invoices

This program permits operators to enter unpaid vendor invoices into the Accounts Payable system. The program should enable the distribution of the invoice to specific general ledger accounts. Controls include:
o check to ensure that the vendor number is on file, i.e., valid vendor number
o ensures that the invoice has not been previously entered, i.e., duplicate entry
o ensures that the invoice has been fully allocated to general ledger accounts
o ensures that the general ledger account numbers are valid
o ensures that items were ordered and received and that prices and other charges are ok

2. Print Payable Checks

This program generates supplier checks to pay outstanding invoices. Controls include:
o ensures that the vendor number on the invoice is valid (i.e., vendor is still on file)
o ensures that checks are used in sequential order
o ensures that only the outstanding invoice amount is paid
o lists the invoices and the amount paid by the check (i.e., the remittance list)
o ensures that negative checks are not printed
o ensures that checks do not exceed a predetermined amount
o ensures that there is an approved, unpaid invoice in the Accounts Payable file before making a payment
