I'm the one who keep track of household exps, pay bills and save for the family. Doing all these as hubby does not have time to look into the details. Just as well, I prefer he does "bigger" things like concentrating on his work and earn more!
Besides these, I also do investment and ensure we get better returns for our $$.
However, I dont have the so-called final say on what we can spend on. We consult each other on big ticket items.
