I used to juggle due dates in my head. Missed two payments in a row last year. Late fees ate like $60 total. Then I made one simple spreadsheet with just three columns: bill name, due day, amount. I check it every Sunday morning with coffee. Took maybe 20 minutes to set up and now I have zero late fees in 8 months. Anyone else find that writing stuff down beats any app?
The "three columns" thing is smart, I read somewhere that most budgeting apps actually make people check out more because there's too much going on. A plain sheet keeps it simple so you actually stick with it. Sunday morning with coffee sounds like the real trick here, not the spreadsheet itself.
