Not sure about you, but I have no need to track my individual balances on a day-to-day basis. IMHO, managing to that detail is only important if you have high balances and are constantly shifting cash from interest-bearing savings/money market accounts and your checking account. This would ensure you are earning the most interest possible on your cash.

The spreadsheet I discussed above ensures that I reserve funds in my checking account for bills that may get paid in an upcoming pay period. I'm not sure how it is in Canada, but my company pays me bi-weekly while my bills are due monthly. As such, I may have a pay period where my bills exceed my actual income. By looking at my finances on an annual basis, I can reserve funds from an earlier pay period to make sure I don't run an overdraft. I also pull out excess cash each month to a separate account to further ensure there are no overdrafts.

This method has worked well for me. I have also applied it to a family member's finances who I now manage.
