One shared credit union account, with a checking, savings, and credit card account.

A spreadsheet that tracks periodic expenses - which produce an average monthly bill that we round up and split, each of us has an automated monthly deposit into the checking account, and the credit card automatically pays itself off from the same account. As many utilities as possible are auto paid by the credit card, the rest auto debit from the checking account. We keep about the checking balance at $1000 minimum to get a higher tier interest rate.

Additionally, we both drop $100 from each pay check into the savings account - so when we want to get or do something fun together, we have some extra sitting around.

At the end of every month, I sit down and draw up a little spending report for where our money has gone - and we either pat ourselves on the back, or grimace and resolve to be a little thriftier next month.
