You can send full refunds - or partial refunds - within 60 days of receiving a payment.

A full refund will refund both you and your payee, you will also be refunded any merchant transaction fees incurred.

If you issue a partial payment refund, the fee refund will be calculated at the same percentage as the payment refund.

For example:
Your customer pays $100.00 AUD of your total invoice.
The fees for this transaction total $2.70 AUD

• $2.40 AUD of this is the variable 2.4% (find out more about the variable % here)
• $0.30 AUD is the fixed transaction fee (which is not refunded for partial payment refunds)
