The Processing Charge feature in Aesthetix allows businesses to automatically add extra fees to customer payments, such as:
Processing charges
Convenience fees
Miscellaneous service fees
This functionality helps businesses offset payment processing costs while presenting clear, itemized fees to customers during checkout or invoicing.
A Processing Charge is an additional fee applied to a customer’s transaction total to cover costs such as payment processing or service-related charges. The fee is visible to customers during checkout and included on their payment receipt.
The processing charge is applied to the amount calculated as:
(Subtotal − Discounts + Taxes)
This represents the actual amount processed through the payment provider.
For E-commerce orders, the calculation is:
(Subtotal − Discounts + Taxes + Shipping)
All fees are rounded to two decimal places before being added to the total.
By enabling this feature, you can:
Define the percentage fee
Customize the label displayed to customers
Choose which payment channels the fee applies to
The fee is automatically calculated based on the transaction amount, ensuring accuracy and transparency.
Processing charges can be applied to the following payment sources:
