There are no setup or cancellation fees for Tap to Pay. There's just a transaction fee that applies to each payment you take using Tap to Pay, but this is passed on to your customer unless you turn off surcharging.
Transaction fee: $0.30 per transaction + 1.6% of the invoice value (including GST).
When a customer pays through Tap to Pay, the fees are deducted from the invoice total and the balance is deposited into your nominated bank account.
Fee example for $100 invoice
Invoice total = $100
Fees = 30c + $1.6 (1.6% of invoice total) = $1.90
If you surcharge (pass on the 1.6% and 30c to the customer), the customer pays $100 + $1.90 = $101.90
If you don't surcharge, the customer pays the invoice value ($100)
MYOB deducts $1.90 in fees from the customer's payment, and you receive the balance
If you surcharge, you'll receive $101.90 - $1.90 = $100.00
If you don't surcharge, you'll receive $100 - $1.90 = $98.10
If there's GST on the invoice, the surcharge will also include GST, which the customer pays it. The app takes care of GST calculations, so you don’t have to worry about it.
