Frequently asked questions
Yes. You can open a new Business Cash Reserve savings account online if you already have a Westpac business transaction account. If you don’t have a business transaction account yet, there are two options:
1. Open a Business Cash Reserve savings account now online (if you’re a sole trader or 1-director company) or open the account at a branch, and we’ll automatically help you open at the same time a Business One transaction account.
2. If you’d prefer to open a Business One Plus transaction account and benefit from special offers and discounts, you’ll need to open that account first (either online or at a branch) and select to open a Business Cash Reserve savings account at the same time.
Before you can connect your accounts in Online Banking, you’ll need to set up a bank feed2 with your online accounting or third-party service provider. Contact your provider to find out how.
Once you’ve established a link to your preferred third-party service provider, follow these simple steps:
- Sign into Online Banking from a desktop
- Select Services
- In the Account service section, select Bank Feeds
- Select your third-party service provider, then select your accounts
- Select Connect feed.
Note: If you’re changing your third-party service provider or a User’s access levels, you’ll need to disconnect your current bank feed before proceeding.
Learn more on how to connect your accounting software.
If you have more than one Business One or Business One Plus transaction account in the same name, any eligible customer-initiated transaction you make on either account will count towards your 10 transactions.
For example: if you completed 5 customer-initiated transactions with a Business Debit Mastercard® linked to your Business One account and completed 5 customer-initiated transactions on your second Business One account that is in the same name, you will receive the Spend&Grow variable bonus interest on your Business Cash Reserve savings account in the same name, as the total number of transactions is 10.
Spend&Grow bonus variable interest is only eligible on one Business Cash Reserve account. If you have more than one Business Cash Reserve account, only the Business Cash Reserve account that you opened earliest is eligible for bonus interest.
Your Merchant facility must be linked to a Business One or Business One Plus transaction account for funds received to be eligible as a customer-initiated transaction. The daily credit settlement of funds received counts as 1 transaction towards your eligible transactions.
For example: If you receive 20 customer payments on your Merchant terminal in one business day, the daily credit settled funds will count towards 1 eligible transaction. If you have 30 days of credit settled funds, this will count towards 30 eligible transactions.

Things you should know
Bank feeds must be set up with third-party service provider before it can be connected in Westpac Online Banking. If your third-party service provider doesn’t appear in the drop-down menu in Westpac Online Banking, you may need to check that your third-party service provider is registered with Westpac. Should there be any changes to your user access or network access levels, you may need to disconnect your bank feed(s) as any access changes won’t impact bank feeds. The products and services offered by third-party service providers are subject to their own terms and conditions and fees and charges. Westpac doesn’t guarantee or endorse the services or products offered by third-party service providers.
