Collecting Rent?

[M Ness]

I'm purchasing my first property and will (hopefully) be renting it very soon. Is the most common method of collecting rent just having your tenant mail the check, requiring that it be received by the first of the month? Do you send them e-mail reminders, or mail them an invoice for that matter, or just hope they remember?

Are there other methods you've used, like setting up electronic payments?
