Hi all! 

I am entering a bill that has some credits and normal charges on it. It ends up as a credit balance. I am just trying to figure out how to put the whole bill in the system. 

For example

service charge $30

regular service $50

**CREDIT** correction for past service $120

Credit Balance of $40

I want to enter this all as one unit instead of making a credit AND a bill. Can I do that?
