You can choose to pass payment processing fees to your customers by adding a percentage-based fee, a fixed fee, or both. This is available for automatic payment methods only (e.g., Stripe, Paystack).
How to Add a Payment Processing Fee
Go to Settings > Payments
Select the payment gateway you want to apply the fees
You’ll see an option to add a percentage-based fee (e.g., 4%) and a fixed fee (e.g., $1)
Click Save to apply the processing fee to all future orders. The customer’s total at checkout will now include the additional fee.
