Invoicing & Billing Specialist

We’re looking for an experienced Invoicing & Billing Specialist to join our client's Customer Service team in Sydney.

This is a newly created role offering the opportunity to take ownership of the end-to-end customer billing process and help establish efficient, accurate and well-controlled billing practices.

Working closely with Customer Service, Finance, Commercial and Operations, you’ll be the key link between commercial contracts, operational activity, customer requirements and financial outcomes.

This is much more than a transactional invoicing role. You’ll be responsible for understanding complex commercial arrangements, analysing operational data, resolving billing discrepancies and improving the processes that support the Order-to-Cash cycle.

If you enjoy working with data, solving complex problems and finding better ways of doing things, this could be the role for you.

As the Invoicing & Billing Specialist, you will:

• Own the end-to-end preparation, verification and timely issuance of customer invoices.

• Interpret commercial contracts and translate pricing structures, volume tiers, fees, conditions and adjustments into accurate billing outcomes.

• Analyse operational data to ensure customers are billed accurately and in accordance with contractual requirements.

• Maintain and audit billing master data within the ERP system.

• Investigate and resolve complex billing discrepancies, account variances and historical reconciliation issues.

• Conduct detailed contract and account reviews to identify billing errors, revenue leakage and opportunities for improvement.

• Work closely with Commercial, Operations, Finance and Customer Service teams to resolve account and billing issues.

• Act as the key point of contact for customer billing enquiries, providing clear, professional and timely responses.

• Develop and document billing workflows, procedures, templates and reporting.

• Identify process gaps and opportunities to improve the flow of information from operations through to invoicing.

• Drive continuous improvement initiatives that reduce billing cycle times, minimise errors and improve cash flow.

• Maintain accurate working papers and documentation to provide a clear audit trail and support audit requirements.

• Support Finance during month-end close with revenue accruals and unbilled revenue estimates.

• Support the training of team members in new billing processes and procedures.

We’re looking for someone who combines commercial understanding, analytical capability and exceptional attention to detail.

You’ll ideally bring:

• 3–5 years’ experience in complex commercial billing, financial reconciliation, Order-to-Cash or a similar function.

• Experience working with commercial contracts, pricing structures, billing rules or customer agreements.

• Strong analytical and problem-solving skills, with the ability to investigate discrepancies and identify root causes.

• Advanced Microsoft Excel skills, including Pivot Tables and manipulation of large or unstructured datasets.

• Experience working with an enterprise ERP system such as SAP, Oracle or a specialised operational management system.

• Excellent written and verbal communication skills.

• The ability to work effectively across Finance, Commercial, Operations and Customer Service.

• A highly organised approach and exceptional attention to detail.

• A proactive mindset, with a focus on resolving underlying issues rather than simply fixing individual errors.

• The patience, curiosity and persistence to investigate historical transactions and reconstruct complex accounts when required.

Experience in logistics, supply chain, manufacturing, industrial, infrastructure, energy or other asset-intensive environments will be highly regarded.

A tertiary qualification in Business, Commerce, Accounting, Logistics or a related discipline is desirable, although equivalent practical experience will also be considered.

This is a chance to take ownership of a newly established function and help shape the way billing is managed across the business.

You’ll have the opportunity to:

• Build and improve billing processes from the ground up.

• Work across multiple areas of the business.

• Solve complex commercial and financial problems.

• Improve billing accuracy and customer experience.

• Identify and reduce revenue leakage.

• Improve the speed and efficiency of the Order-to-Cash process.

• Make a tangible impact on cash flow and business performance.

If you're someone who enjoys turning complex data into clear answers, solving problems and improving processes, we'd love to hear from you.

If you’re ready to take ownership of a complex commercial billing function and help build a better way of working, apply now.
