We are interested in disabling the "pay balance" feature in sage 100ERP  (version 5.20.2.0 ) with regard to credit card transactions. 

We have a glitch that occurs at our invoicing step that is sending a signal to SAGE PAYMENTS to charge the card a 2nd time after a deposit amount has been done in the sales order. 

We do not use the "pay balance" feature and wish to remove it.

Can someone please provide a white paper or instructions on how to remove this feature?  

Thank You.
