What’s the difference between an overdraft and a business loan? 

A business loan is a lump sum paid into your transaction account. An overdraft is a pre-agreed amount you can access if your bank balance drops below zero. 

A business loan may suit your business if you need funding for things such as a business acquisition, start-up costs, capital investment, property acquisition or development, or refinancing other lending. 

A business overdraft may help relieve the strain on your cash flow, by supplying funds to cover expenses (such as buying stock and paying invoices and wages) until you get paid by your customers.

Secured and unsecured overdrafts: what’s the difference? 

If you want access to less than $250k, an unsecured business overdraft may suit your needs. An unsecured overdraft can provide more funds in your business transaction account, without you having to offer a specific asset (such as a property) as security against the ‘loan.’ Please note that a director’s guarantee will be needed if you’re a corporate borrower.  

If you’re looking for an amount above $250k, you could consider a secured business overdraft. This means we give you access to more funds in your business transaction account, and you provide security for the overdraft with a specific asset.
