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 fast-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 professional 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 environment.
- 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.
