Here’s an awesome tip for tracking expenses across multiple credit cards and back accounts.  You basically create a form in Google Docs for entering an expense and then email the form to your email account. In your email client, save the email in a convenient location and then simply fill out the form attached to the email and submit it each time you have an expense. If you use Gmail, you can set up a Quick Link and quickly access the form in Gmail. The same principle could be used for all kinds of applications:

• Keeping track of tracking numbers.
• Entering investment purchases or sales.
• Creating a grocery list.
• Generating a to do list.
• and more!

If you are like me you spend a lot of time in your inbox, so being able to keep track of stuff using email is a huge convenience.

Use Gmail and Google Docs to Track Expenses
