Settlement and transaction times

How long before settlement reaches my account?


If you have a Westpac account, EFTPOS machine funds will be paid into your account instantly after your terminal completes settlement each day, 365 days of the year. If you are settling into a non-Westpac account funds will be paid into your account within 48 to 72 hours of settlement. These times exclude Fridays, weekends and NSW public and bank holidays.



Online funds will generally be paid into your account within 24 hours if you have a Westpac account. Settlement occurs at 6.00pm Australian Eastern standard 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 to dispute it?

Chargebacks may be processed to your account up to 12 months after the date of the original transaction.

Can I have my merchant fees reviewed?

Yes. Simply telephone the Merchant Business solutions help desk on 1800 029 749 and select option 1.

Can I close my merchant service before the expiry date of my contract?
