//Design a Solution to help a dental care office with automating the billing process

//the office administrator would like to send bills at the end of every month, and each bill needs to have the following information:

//Patient's Name

//Bill-To Name - If the patient is insured, it wil be the patient's insurance provicer name, otherwise it's patient's name.

//Bill-To Address - Same as above

//Bill Amount - This is the sum of all service charges rendered to the patient on all the patient's visits during the month.

//Billed Services

//Days Past Due - This will be zero for new bills and will be updated when an unpaid bill is resent during the month.
