How to give refund to the patient

Can any one suggest my how i gave the refund amount to the patient.

@Rakesh , You have to write code for this. I don’t think there is refund functionality

  1. Is there any module for advance payment?
  2. What is the role of batch payment module?
  3. can i use batch payment>pre_payment for advance payment?

Can you guide me for developing this module. Not need a very large help but a simple assistance, i think you are very familar with openemr.

@Rakesh Please send me your more detail into below email id nbhbiotech.hake@gmail.com
