Tap to Pay is set up so that you pass on transaction fees to customers. This means that the transaction fees ($0.30 + 1.6% of the invoice value) are added to their invoice as a surcharge. The surcharge is then deducted from their payment before the balance is deposited into your bank account within 2 business days.
When you first set up Tap to Pay, surcharging is automatically enabled, but you can change this setting at any time.
GST on surcharges
If there's GST on the invoice, there will also be GST included in a customer's surcharge. If there's no GST on the invoice, there will be no GST applied to the customer's surcharge.
The app takes care of GST calculations, so you don’t have to worry about it.
