How do you accept rent if self-managing apartment?

[Sharon Beatty]

This is a newbie question - what service do you use to accept rent money when you're managing the property yourself? We're using a property manager right now for the basement apartment we just created in our house. It seems  like an extra step for communications, especially when we just live upstairs. I just don't want to accept checks if I can help it - do people use Venmo or are there apps out there specifically for rent collection? 

Thanks!
