A winning spreadsheet could make you a fortune. If you could effectively identify what many people want and are willing to pay for, and can make your spreadsheet easily accessible, you could be cashing checks for the rest of your life.
You may want to create a workbook with multiple sheets for various aspects of your budget. You can have one sheet that keeps track of savings and investments and another sheet that lists your monthly bills.
The common feature among the spreadsheets templates is that they save time and effort and also they make the work and other calculations easier. Planning out things and fast access to data and other information are made very easy when using spreadsheet templates. But most of these templates are unique according to the purpose. The templates can be saved and used as many times as required.
Using Excelville.com, there are no costs associated with selling spreadsheets and you don't need to build and manage a separate site, which works out pretty well. Whatever path you take, I wish you the best of luck. Leave a comment and let me know how things are going for you.
