How to best collect rent?

[Wenhao Leu]

Hello! I am a newbie landlord thanks to BiggerPockets. I found my lender here and networked with many real estate professionals here. This is just such a useful site!

Just a quick question for all the experiences landlords out there. What is the most efficient and cheapest way to collect rent?

I would really prefer to put my tenants in an automated debiting system that we don't have to worry about rent coming due and all that. Any suggestions? Helps and info are highly appreciated.
