I need the BPMN flowchart, please! Don't just have text descriptions.

Flow Co is a company that makes custom flowcharts. Their A/P department is responsible for receiving, processing, and paying all vendor invoices. The process begins when the A/P clerk receives a vendor invoice in the mail. The clerk reviews the invoice and performs a three-way match against an available receiving report and purchase order. If these documents match, the invoice proceeds to payment. If these documents do not match, necessary changes must be reviewed and approved by an A/P supervisor before proceeding to payment. Payment is performed by the A/P clerk, who creates a check. If this check is below $1,000 it is autosigned by the system and sent to the vendor by the A/P clerk, ending the process. If this check is above $1,000 it must be reviewed, signed, and sent to the vendor by the A/P supervisor, ending the process.
