Reminder to collect rents from delinquent tenants

[Aqil Dharamsey]

Hello fellow BP Investors and landlords. we all experience from time to time tenants that don't pay on time. After adding a lot of properties in the rochester NY area to my portfolio in the last 2 years, it is becoming harder to keep track on who has paid and who still owes rent or has a balance. At the moment I am writing things down on pieces of paper but was wondering if there was some sort of reminders or programs that I can access on my phone on the go. Any input will be greatly appreciated. Thanks! Aqil
