Frequently asked questions

BizExpress is a faster way for eligible businesses to apply for business loans and finance. It's used when you apply online and may also be used when you apply through a Banker. With BizExpress, we use information that we already hold about you or that you supply to streamline and speed up your application process. 

You can access the money through your Business Transaction Account, using the usual methods: NetBank, the CommBank appCommBiz, at CommBank ATMs, in branch, over the phone or through EFTPOS and cheques.

With a loan, you’re given the amount in a lump sum and charged interest on the whole amount, which you'll pay off over a period of time. Loans are generally taken when you need to make a purchase upfront and in full.

An overdraft is linked to your transaction account and allows you to access additional funds when your account balance reaches zero. You’re only charged interest once you use the money, and you’re only charged interest on the amount you use. Overdrafts are a way of making sure money is there if you should need it. For example, to manage unexpected expenses.
