About Additional billing method
The content of the question is about the additional billing method.
I found that I sold few charges by mistaking the billing unit price.
Is there a better way to charge less for billing next month?
What we are assuming is a method of registering a single invoiced product additionally and only requesting this time.
If there is any other good way, please let me know.

the suggested way to fix this is creating amendment against the subscription to update the billing unit price. you can also crInvoiceovice Item Adjustment in invoice but you will need to do this in every new invoice as the price in the subscription is mistaken.
