Hi I find this app super nice and am thi king about using it for our non profit artist coworking space.
One question: Is there a possibility to set abovementioned, and also calculate the actual balance based on that?
I.e. if the montly rent is 100 , we are in the first month of the rental , like 4.4.2016, and one payment of 100 has been made. Then the balance should show 0 if the set "due date" is say 20.4.2016. From 20.4.2016, if there has not been another payment, the balance should show -100.
I hope i could convey what i meant ;-)
