Here are some great online budgeting tools to help you get started on budgeting:

Microsoft Office offers custom budget templates: http://office.microsoft.com/en-us/templates

A great budgeting tool I use and love is Mint.  It sends alerts based on personal information and settings.  Great Mobile App as well:

For a small business, I highly recommend the use of QuickBooks.  This is what I use for my small business to keep track and send out invoices.

You might also find that a simple Excel spreadsheet, Word document, or old fashion pen and paper works for you.  Whatever format you choose is less important than making sure you consistently update, review, and follow your family or business budget.
