Hello experts.
I have configured a billing plan that makes monthly billings from the beggining to the end of a contract. However, it is common for a client to start a contract somewhere in the middle of the month. So, in the first month I have to bill him only a portion of the montlhy value.
For example, I have a service contract that bills US$1000,00 monthly. But in the first month, I have to bill only half of this because the service started in the 15th (middle of the month). How can I make the first line of the billing plan bill only 500 dollars?
