Full Job Description

Be part of something big — where getting it right matters.

At Certis Security Australia, we deliver innovative, integrated security solutions that create safer environments — including major events and high-profile sites across Australia.

Our commitment is to a Safer, Smarter and Better workplace, where people are supported, respected and empowered. As Australia’s only next-generation security company operating at scale, we’re transforming how we work through technology, automation and operational excellence.

Behind every safe, successful operation is accurate data and disciplined processes. That’s where you come in.

As a Billing Officer, you’ll play a key role in protecting revenue and supporting cash flow by ensuring invoices are accurate, timely, and compliant.

Your attention to detail helps prevent downstream credit and collections issues, keeps customer confidence high, and ensures financial records are audit‑ready. Getting billing right means everything that follows runs more smoothly — and your role sits right at that foundation.

About the Role

This is a detail‑driven, process‑focused role for someone who enjoys structure, accuracy, and working with systems.

Reporting to the Billing Team Leader, you’ll prepare and issue invoices, resolve billing queries, and work closely with Operations, Credit, and Collections teams to ensure billing reflects contracts, pricing, and service delivery. Budget for this role is $75,000 plus super.

What You’ll Be Doing

Billing Operations

Prepare and issue invoices in line with billing schedules, contracts, and pricing agreements
Validate billing data to ensure accuracy and completeness before release
Apply approved adjustments, credits, and rebills within delegations and controls
Complete billing within agreed timeframes and billing cycles

Billing Queries & Issue Resolution

Respond to customer billing enquiries professionally and within service standards
Investigate discrepancies and work with internal teams to resolve issues
Escalate complex, high‑risk, or non‑standard billing matters when required
Support timely resolution to prevent downstream credit or collections impacts

Compliance, Controls & Documentation

Follow internal controls, approval pathways, and audit requirements
Maintain accurate, complete, and audit‑ready system notes and documentation
Use approved processes, templates, and communication standards

Systems & Reporting

Use billing and finance systems accurately and consistently
Maintain up‑to‑date billing records and supporting data
Support reporting, audits, and reviews as required
Identify recurring issues or improvement opportunities

Team & Stakeholder Engagement

Work closely with the Billing Team Leader and broader Finance team
Liaise with Operations, Credit, and Collections teams to resolve billing issues
Contribute to a professional, reliable, and cooperative team environment

About You

You’re organised, detail‑oriented, and confident working with numbers — someone who takes pride in accuracy and consistency.

You’ll bring:

Experience in billing, invoicing, or finance operations
Strong attention to detail and time management skills
Experience working with financial or billing systems
Ability to manage deadlines and competing priorities

Bonus points if you have:

Microsoft Dynamics 365 experience
Experience in a contract‑based or high‑volume environment
Exposure to credit or collections processes
A certificate or tertiary qualification in Finance, Accounting, or a related discipline

Benefits & Culture

What We Offer:

Technology-led, intelligent security and facilities management solutions across Australia’s most critical sectors.
Collaborative, fast-paced work environment with hybrid work arrangements.
Commitment to diversity and inclusion; applications encouraged from women, Aboriginal and Torres Strait Islander peoples, and candidates from diverse backgrounds.
Employee benefits such as retail discounts, annual awards, Regular employee engagement survey and a Reward & Recognition Framework

Next Steps:

Once you’ve submitted your application, the next step is to complete a virtual interview with Certis.

This is an important part of our hiring process and must be completed for your application to be considered further.

After you’ve finished your virtual interview, our hiring managers will review all candidates. If you’re successful in progressing to the next stage, we’ll be in touch to let you know what’s next.
