Home Basics: How Do You Keep Track of Household Finances?

As a a carefree, single person I did not track my finances closely even though I should have. I had a good paying job and only a few bills and no problems paying them. However, once I got married I realized that the merging of my husband's and my student loans, scholarships, and work study money (we were both in post graduate programs) needed to be monitored. And now that we have re-entered the workforce we still watch our dollars.

We have evolved from a basic Excel spreadsheet to Quicken to Mac Moneydance and back to Excel again. One of my closest friends swears by the Home Budget app to sync her and her spouse's finances.
