Under Features, select Invoicing
Click Payment policy
Click Configure Transaction Fees under Payment gateway transaction fees
Enable Add transaction fees and specify the amount that you'd to charge your Users for each transaction
Click Save
Note: Within the invoice, Optix will show the transaction fee based on the User's current default payment method OR the last payment attempt (if the User chose a different payment method)
Note: The fee that the User will pay is based on the type of payment method used for the particular payment. This means that if the User is using a credit card, they will only be charged the transaction fee that you have specified under the 'Credit Card Fee' field.
