DH makes all of the money. I manage it.
His paycheck is direct deposited into our joint account (we have a joint checking & savings, no separate accounts). I pay all of the bills, and we both spend from the account. I create the budget and show it to him, so that he knows what the "plan" is, but neither of us has a true spending limit and definitely not an allowance of any sort. We have a number of what we'll spend a week on food, gas, and miscellaneous expenses. We talk to each other if we've bought something that's at all out of the norm (or more often, if we're going to buy something out of the norm) so we can decide where it's going to come from. Honestly, DH very seldom has to make a true financial decision... he is a large participant in large purchases, but leaves pretty much everything else to me. He is glad not to have that worry.
We've always handled our money this way, the same when I was working, my paycheck was also deposited to our account and handled this way. We have friends who do it differently and often argue about financial issues, as well as how one spouse is 'poor' and one is living it up, etc etc. Idk... that's just not for us. We view our marriage & family as a team, and our finances are our teams' funding... we're all in it for the same thing.. to pay the bills, take care of one another, save a bit, and enjoy life.
For the number-happy, DH and I have also done fun little calculations of my "financial worth" as a SAHM... if we had a nanny, ate out twice/week (due to my being late from work or something), if I wasn't home couponing, making supplies from scratch, etc etc etc.. what would that "cost" us? I really feel that SAHPs have not only a role value, but also a true economical value and I am glad DH sees it that way too.
