Summary: Senior Billing Analyst – Centralized Billing

The Senior Billing Analyst is an experienced member of the Centralized Billing (CB) team who operates with a high degree of independence, taking full ownership of the most complex branches, accounts, and billing scenarios. Positioned between the CB Team Lead and the Billing Analyst, this role combines strong individual execution with a mandate to identify and drive process improvements, uphold quality standards across the team's output, and act as a technical and functional escalation point. The Senior Billing Analyst is expected to work with minimal supervision, exercise sound judgment on non-standard cases, and contribute to the continuous maturity of the CB function.

Supervisory Responsibilities:

• None on a formal reporting-line basis.

Duties and Responsibilities

• Independently own the full invoicing lifecycle for assigned high-complexity branches, customers, or verticals, with minimal need for oversight.


• Act as the primary escalation point for billing exceptions, disputes, and non-standard scenarios that exceed the scope of Billing Analysts.


• Lead root-cause analysis of recurring billing errors or delays and drive corrective and preventive actions to closure.


• Identify, propose, and implement process improvements to CB workflows, tools, and documentation, and lead basic testing/UAT for changes to systems or procedures.


• Own the quality and timely resolution of entries in the CB Exceptions Log for the assigned area, including trend analysis and escalation to the GBS Manager where needed.


• Review and quality-check the work of Billing Analysts, providing constructive feedback and coaching to raise accuracy and consistency.


• May provide day-to-day guidance, coaching, and quality review to Billing Analysts, and support onboarding of new team members and new branches.


• Support the CB Team Lead and GBS Manager in onboarding new branches or regions into Centralized Billing, including documentation and knowledge transfer.


• Handle complex VAT, tax, and finance-compliance scenarios that require specialized judgment before invoice posting.


• Maintain and monitor Power BI dashboards and reporting relevant to the assigned scope; flag anomalies proactively rather than on request.


• Partner with Operations, Finance, and regional stakeholders (including local Managing Directors' teams) to resolve structural issues and improve data quality at the source.


• Contribute to capacity planning by providing accurate, timely input on workload, volume trends, and staffing needs for the assigned area.


• Ensure full compliance with the CB SOP, proactively flag gaps or inconsistencies, and contribute updates to keep documentation current.


• Act as a change agent, promoting adoption of new processes and tools and supporting others through change with a constructive, solutions-oriented attitude.


• Support monthly, quarterly, or ad-hoc reporting and analysis, often defining the approach rather than simply executing it.

Required Skills and Abilities:

To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed below are representative of the knowledge, skill, and/or ability required. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.

• Strong analytical and root-cause problem-solving skills; comfortable making decisions on ambiguous or non-standard cases.


• Advanced proficiency in CargoWise (or equivalent billing/ERP systems) and Power BI; strong general IT and Microsoft Office skills.


• Experience coaching or mentoring junior team members, with the ability to give clear, constructive feedback.


• Excellent stakeholder management skills, with the credibility to work confidently with global and local APAC audiences, including senior operational and finance contacts.


• Highly organized, quality-focused, and accountable for outcomes rather than just tasks.


• Proficient in English, both written and spoken.
