Best FREE Expense Tracking Software

[Jeb Brilliant]

Hi All, 

I need a little help. Can you recommend a FREE software to track income/expenses for an apartment I purchased with some partners? They need to be able to access it so cloud based would be best. I am NOT great at keeping track of things like this usually so simple would be good and maybe something that I could someday export into Quickbooks or something like that would be helpful. 

Honestly if someone just has a spreadsheet they really like I'm fine using that as well. 

Thanks in advance!
