Card transaction fees differ according to the plan you’re currently subscribed to and the card type used by your customers.
* Foreign cards include Amex.
How does it work?
When your customers pay your invoices online by clicking on the payment button on the invoice, the transaction fee will be deducted from their total amount paid.
You can turn on Fee-Pass-Through in order to pass this payment fee onto your customer. However, the additional fee for foreign cards and Amex cards is unable to be included in this Fee-Pass-Through feature.
In order to get lower fees, you can upgrade to a higher plan. The higher the amount you get paid with debit or credit cards, the more significant the lower fees will be for you.
