Bills that are auto-paid.
Bills that are late.
The auto-paid ones are completely on auto-pilot. If I have a particularly heavy spending month (maybe we took a trip somewhere), I might open my bank app to make sure there's enough cash in the account to cover the auto-payment. (Or I might not and either there will be, or auto-overdraft-protection will kick in and I'll end up paying a few bucks in interest.)
I just mentally went down the list and it hurts me to admit it but that's the exact same for me.
You’d just see the overall bill slowly creep up with no clear cause. Frog boiling.
The only "pure" argument here would be to pay with cash, but the logistical cost heavily outweighs the psychological value if you go down that path, in my opinion.
It's time well spent — making sure I am paying for the things I really need/want.
When everyone under the sun seems to be playing games? It’s a good way to get taken advantage of.
All of my "manual" bills work that way. It takes a few seconds of clicking to schedule the payment on the due date for the full amount, and even log it to my software, which doubles as a chance to check that there wasn't something unexpected going on.
I think being fully aware of every bill or credit card you pay is helpful in being full control of your finances. I get that impression that some people using automatic payments don't slow down to review things carefully. That may not be the case for you, but that doesn't mean others don't make that mistake.
What I think trips people up is accounting for future expenses. The personal finance tools I've checked out focus on historical transactions but fail to put this to use and forecast future transactions. I set up GNUCash[1] to automatically create all the random monthly bills up to 3 months ahead of time, including a guess at CC totals.
I still check monthly, but its mostly just confirming nobody's stolen my card and updating my investments, which I can't forecast ahead of time =)
Every two weeks I check all credit cards, pay my mortgage, utilities, etc.
