Not sure what exactly you mean by money management, but to have an overview of my finances, i.e. see all credit card, brokerage and checking accounts at once, and to track spending, mint.com is awesome. It saved me a fair amount of money once when I caught a credit card fee I was unaware of and missed on my statement, and I could call and cancel that service in time to get a full refund.

It's a bit unsettling to give all your financial account logins to a third party website, but I trust that a company like Intuit has decent security...
