Best program to use for keeping track of expenditures

[Bleau Deckerd]

Hi All! I am looking for the right program to begin keeping track of expenditures and receipts. Currently we have a custom home/spec home business and we just purchased a few rentals which will give us another LLC to manage. I would like a program that allows us to manage the finances for multiple businesses. The important factor is I want something that allows me to take pictures of receipts and then send them to the program through an app so I don't have to keep track of the paper copy. The #1 important factor is it needs to be user friendly. Any help and advice is appreciated.
