For me in the Netherlands. I have one bank account, salary comes in, all bills are paid automatically, some money gets automatically transferred into my savings account.
Pension gets taken out of my paycheck automatically as well, so not doing anything special for that. In the rare cases I use a credit card, it will automatically be paid off as well, so nothing really to worry about there either.
I have recently bought my own place, so once savings are back to a safe level I’ll start to make a monthly investment in some index fund.
