Revenue Share among owners

[Mitch Gilman]

I currently own 3 properties and I am quickly realizing that I don't have the proper systems in place to keep track of who owns what with regards to cash flow and revenues. I am looking for suggestions on how to best keep track of all of this. 

For Example:

House A - I own %50 and my partner owns %50

House B - 3 owners, split evenly

House C - I own %20 and my partner owns %20 and a 3rd owner has %60. 

We have an LLC for each property. An additional question is, does it make sense to have a separate bank account for each property or should they all flow into the same account? I am really just trying to simplify this as much as I can so that when we have 5,10,15 properties, it is easier to keep track of who owns what.
