The Opportunity

n

We're looking for an experienced Office Manager who enjoys wearing multiple hats and being the person who keeps a business running like clockwork.

This is far more than a typical administration role.

If you enjoy ownership, autonomy and variety, this is the role for you.

n

You'll suit this position if you've previously worked in heavy equipment, crushing & screening, truck, transport, industrial, manufacturing or another rapid-paced operational business where accuracy, organisation and commercial awareness are second nature.

n
- Processing customer orders, invoicing and purchasing
n
- Managing Accounts Payable and Accounts Receivable
n
- Following up outstanding accounts using a professional customer service approach

- Maintaining accurate records across Oracle, NetSuite and inventory systems
n
- Coordinating with the external Accountant for BAS and statutory reporting
n
- Providing executive support to the Directors while delegating tasks to the Personal Assistant where appropriate
n
- Continuously improving office systems, processes and efficiencies
n

n

What We're Looking For

n

n
- A self-motivated, hands‐on team player who takes ownership and thrives in a fast‐paced, cross‐functional environment.
n
- Strong Accounts Payable & Receivable experience
n
- Purchasing and inventory administration experience
n
- Excellent organisational and communication skills
n
- Solid CRM and ERP system skills, with NetSuite or Oracle experience highly desirable.
