The Opportunity

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. You'll become the operational backbone of the business, working closely with the Directors to oversee office administration, accounts, purchasing, inventory, customer follow-up and business systems. If you enjoy ownership, autonomy and variety, this is the role for you.

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

What You'll Be Doing
Managing the day-to-day office operations and administration
Processing customer orders, invoicing and purchasing
Managing Accounts Payable and Accounts Receivable
Following up outstanding accounts using a qualified customer service approach
Assisting with payroll through an automated ERP system
Managing inventory, stock movements and supplier deliveries
Supporting purchasing and imported products,



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

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