please show me an example of how to start flowcharting or give me an idea..

Required: using Word, flowchart the following document flows for Pea Blossom's credit sales system.

Internal controls: customers email or fax their purchase order document to pea blossom's sales staff. The information is keypunched into the company's mainframe computer, which checks the customer's approved credit limit against the customer balance master file, and, if approved, then prints a three part pre-numbered sales order document. Copy 1 is sent to the credit manager Brenda Roberson for her initials to indicate approval for the sale.This approved copy is then sent to the accounting department. Copy 2 is sent to the shipping department in the inventory warehouse. Inventory and sales order copy #2 are shipped to the customer. Copy 3 is filed in the sales department by customer name.

Using the approved sales order #1 from above, the Clerk in the accounting department keypunches the sales transaction into the computer, which produces a daily sales journal report and prints a three part pre-numbered sales invoice. Copy 1 is mailed by the clerk to the customer to bill for the sale. Copy 2 is sent to the sales department where it is matched with sales order copy #3 and filed by customer name. Copy 3 is filed by accounting department by invoice number.
