accepting rent in multifamily

[Dave K.]

How are you structuring your bank accounts to accept rent, to know who paid, if you have an automated/online system?

I have a 4 unit, that i have turned over from section 8/low income, to student housing.     I have tenants that want to pay by the year, some by the semester, and some by the month, all in the same apartment.    

Since i only have 4 units, i am planning to do 4 separate bank accounts, but that got me to thinking, how do they keep track of the big multi units?    website with login? paypal? etc

@Dave K. , I've seen other landlords alter the rent amount slightly, so you know who is paying what. Apartment A is $500, Apartment B is $501, Apartment C is $502 and Apartment D is $503.
