The functionality to create Customer prepayment invoices is available in the product. As per the GST law in India, GST needs to be recorded on such customer prepayment invoice. Presently, the system includes the GST amount on the Sales order for calculating the Prepayment invoice amount, but such GST amount is not recorded as GST payable in the system i.e. GST is not recorded separately but is grossed up in the prepayment invoice amount.

However, the requirement is to record the GST amount on customer prepayment invoice separately as GST payable.
