Help with creating a Excel spread sheet

All I need is an excel made so that I can calculate my businesses transactions and profit for the day/week/month. Also I would like the daily/weekly/monthly averages of how much profit I have made. Then I want a part to keep track of the running total for the day. Field 1 (Product Name) Field 2 (Cash value of product) Field 3 (Amount Paid for Product) Cash value - Amount Paid = Profit Running total for the day
