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.
From businesses to non-profit organizations, spreadsheets are used in different sectors, ranging from Entertainment to Culture to Education and to Health to name but a few. With the emergence of home-based businesses and an increase in the number of entrepreneurs in the marketplace, such software is now highly sought-after among home users as well.
Another advantage to using a spreadsheet application for your budget is that you won't have to access the Internet to access your budget. You will be able to view it or work on it wherever you are and if you typically work on a laptop computer and take it with you when you travel, this can be extremely beneficial. Using budgeting spreadsheets to manage your finances is an easy and affordable way to stay on top of your financial game.
You'll need to include more than a basic level of development and calculation in your spreadsheet. There are lots of free spreadsheets on the web. Most of which are very simple and easy to build. People aren't going to buy a spreadsheet that they can get for free. Take yours to the next level by adding all the value you can imagine. Then research on how you can offer a little bit more on the development and functionality side.
