Merchant Agreement

1 – Your Merchant Facility Agreement

Updated the list of supporting documents that form part of your Merchant Facility Agreement by removing references to the conditions for surcharging requirements and adding a reference to the conditions of the Direct Debit Request Service Agreement.

2 – Definitions and Interpretation

Introduced a new definition for “Non-Cash Payment Surcharge”.

6 – Surcharging

Updated surcharging requirements to reflect regulatory changes:

• From 1 October 2026, merchants must not apply a “Non-Cash Payment Surcharge” unless expressly permitted by Law or regulation.
• If a merchant is expressly permitted to apply a “Non-Cash Payment Surcharge” by Law or regulation, the surcharge must be clearly disclosed before processing the transaction and included within the transaction amount rather than processed separately.

Updated to clarify that merchants may process refunds using a BankSA approved refund channel, including online portals or dashboards, even where the original transaction was processed through a different approved payment method.

Fees and charges in detail

• Updated the statement cycle explanation to clarify that merchant statements are issued monthly, although the statement period may not correspond to a calendar month.
• Updated the description of “Volume” to clarify that volume-based fees are calculated on the value and/or number of sale transactions plus the value and/or number of refund transactions.

Our Fees Explained

• Updated the information relating to the “Monthly Terminal Fee” to simplify the fee explanation.
• Updated to clarify that the “Flat Transaction Rate Merchant Service Fee” is subject to periodical reviews and may be adjusted twice per year (at the start of April and October) to reflect changes in processing costs. Merchant customers will be notified of any rate changes in writing or electronically.
• Updated to clarify that the “Flat Transaction Rate Merchant Service Fee” pricing arrangement applies only if international sales transactions (sales transactions processed using foreign-issued cards at your merchant facility with BankSA) represent less than 25% of the total sales turnover over a six-month period. If your merchant facility no longer meets these eligibility requirements, we may transfer your facility to a different pricing arrangement. We will notify you before any change takes effect.
