About Us

We are returning to our roots. Since 2023 AE Smith is a privately owned business once more, and its an understatement to say we have gone through a bit of a transition period. We are still the same organisation that has operated for over 120 years as an Australian industry leader in HVAC, building services and electrical markets, but we have a renewed approach to the way we work and operate. As asset specialists, we understand our asset is our people. We're proud of our team's depth and breadth of experience and with over 600 of us united in our work and our brands, it's unsurprising our average employee tenure is market leading, but we are always keen on adding new faces to our team.

About the role

Based in our Hawthorn East office, we are looking for an experienced Billing Administrator to join our Operational Support team. This role is responsible for ensuring billing and related financial administration is completed accurately, efficiently and in line with contractual requirements and business deadlines.

This is not simply a data-entry position. The successful candidate will understand how their work contributes to regional and functional billing volumes, cash flow, margin performance and broader financial targets. You will work closely with operational managers, service teams, finance and other support functions to resolve issues, maintain billing momentum and help the business achieve its monthly objectives.

The setting is fast-paced, and priorities, processes and information will not always be perfectly defined. We are looking for someone who is resilient, adaptable and comfortable working through changing requirements and a reasonable level of ambiguity. You will need to use initiative,



ask the right questions and keep work moving without compromising accuracy or compliance.

Key responsibilities

- Process service, maintenance, reactive and quoted-work billing accurately and within required timeframes.
- Manage a high volume of billing activity while maintaining attention to detail and work quality.
- Monitor individual, regional and functional billing volumes and contribute to the achievement of monthly financial and operational targets.
- Review work orders, technician inputs and supporting documentation to ensure billing requirements have been met.
- Ensure invoices comply with customer contracts, agreed rates, documentation standards and client portal requirements.
- Identify and resolve missing information, pricing discrepancies, rejected claims and other issues that may delay billing.
- Apply basic financial and commercial principles, including revenue, cost, margin, GST and invoice calculations.
- Work with Service Delivery Managers to prioritise urgent billing and address operational or commercial queries.
- Assist with accounts receivable, accounts payable, finance queries and aged-debt resolution where required.
- Prepare and contribute to financial and operational reporting.
- Build effective working relationships with operational teams, finance, customers,



subcontractors and suppliers.
- Support improvements to billing, procure-to-pay and reporting processes.
- Maintain compliance with company policies, contractual requirements and reporting deadlines.

About you

You will suit this role if you take ownership of your work and are motivated by producing accurate, timely outcomes. You understand that successful billing is measured not only by the quality of individual invoices, but also by the team's ability to meet volume, revenue and cash-flow targets.

You are comfortable working in an environment where priorities can change quickly and where resolving an issue may require investigation, judgement and follow-up across several teams. You remain calm under pressure, recover quickly from setbacks and can adapt your approach as business and customer requirements evolve.

You are likely to have:

- At least five years' experience in billing, service contract administration, finance administration or a similar operational environment.
- Experience working in a high-volume, fast-paced role with competing priorities and firm deadlines.
- Strong attention to detail and a demonstrated commitment to accuracy.
- A practical understanding of basic finance and accounting concepts, including revenue, costs, margins, GST and aged debt.
- The ability to interpret contracts, agreed rates, work-order information and supporting documentation.
- Experience using an ERP or financial management system, with SAP experience highly regarded.
- Strong Excel and general Microsoft Office skills.
- Sound analytical and problem-solving ability.
