I love that it keeps track of all my finances, including tithes/offerings! It is very easy to use once you get used to how things work with this program.
The only thing i don't like about flockbase is when someone leaves there church they are no longer able to access their account so we have had issues in keeping up with our records for people who leave or transfer churches. We also do not know if anyone has transferred into another ward (church) which makes tracking transfers difficult as well since everyone's names change but still keep your own record of where each person belongs within the organization. This helps us organize everything from tithing money to expenses to donations.
