It's in a nice little wooden box on my desk. I pick a large bill when my wallets looks to be emptied. If I need to buy something online, I fill my bank account a little. I don't see the need for management, I know in my head how much I have. I tried to set up spreadsheets, apps or other fancy things to keep track of my spendings, but I abandoned all of them in a few days due to lack of motivation. I wish I had your problem :)
