Does anyone pay their bills twice a month (half each time) instead of once a month?

I know that paying your bills twice a month, half the amount each payment, will save you a ton of interest. Is there anything special you have to do, like inform the payee you’re doing this? I’m also worried that if I start doing it, somehow I’ll be charged a late fee since each of my payments is half the required amount. Anything I need to know before starting this? Thanks!
