Use the narrative below to create a flowchart.

Upon receipt of an invoice from a vendor, the purchasing agent, Cheryl Palmer, matches the invoice with a receiving report that she has previously received from the storeroom clerk and one copy of the purchase order that she has retained from the prior purchasing process. The receiving report and purchase order are stored in a paper file alphabetically by vendor name until receipt of the invoice. Cheryl sends all three documents to the accounts payable clerk, Dave Dull, who prepares a payment voucher. Dave combines all four documents into a voucher package and transfers the package to the controller, Mr. Shelton. Mr. Shelton then reviews the package and either approves or does not approve it. If he does not approve the voucher, he voids the voucher, files it by date, and sends the other three documents back to Dave to re-prepare. If Mr. Shelton does approve the voucher, he initials the document and gives the package back to Dave. After having the voucher approved (initialed) by Mr. Shelton, Dave uses the invoice to update the accounts payable subsidiary file (subsidiary ledger electronic form). The voucher package (invoice and supporting documentation) is then filed in the unpaid bills paper file by due date. On the payment date, the vouchers and supporting documentation are sent to the cashier, Pam Lewis, who manually prepares the checks. Pam forwards the checks and supporting voucher package to Cheryl Palmer, the purchasing agent, who verifies the amount. If the amount is correct, Cheryl records the amount in the cash disbursements file (cash disbursements journal electronic form). She then forwards the approved voucher package and check to Mr. Shelton, the controller. If Cheryl notes that the check is not for the correct amount, she sends the check and voucher package back to Pam to correct. Once the controller, Mr. Shelton, reviews the invoice and signs the check, he sends the voucher and check to the treasurer, Ms. Stockton, to do the same. After signing the check, Ms. Stockton cancels the voucher and sends the cancelled voucher and check back to the accounts payable clerk, Dave Dull, who mails the check to the vendor and files the cancelled voucher package by date.
