Frequently Asked Questions

How long before settlements reach my account?

EFTPOS

With Westpac instant settlement you can access your Westpac EFTPOS terminal takings almost instantly after settlement into your Westpac transaction account once every day by 9:30 pm – meaning you can start using your earnings immediately1.

Online/eCommerce

Online funds will generally be paid into your account within 24 hours if you have a Westpac account. Settlement occurs at 6:00pm (Sydney time) for online/eCommerce merchant facilities. On weekends and public holidays funds will be received the next business day.

How long after a transaction is processed does the cardholder have the right to dispute it?

Chargebacks can be processed to your account up to 18 months after the date of the original transaction. That’s why it’s essential to take steps to minimise fraud and chargebacks as set out in our Merchant Agreement documents.
