  • Own the end-to-end tracking and coordination of all supporting documentation provided to the client for monthly cost-plus billings. Maintain a complete, traceable register linking billed costs to supporting records and tracking submission dates, client queries, outstanding requirements, and resolution status. Coordinate with relevant teams (procurement, subcontract, cost control, AP) to obtain missing evidence, retain a clear record of all submissions and responses, and follow outstanding items through to closure, escalating delays or unresolved issues to the Finance and Admin Lead.
  • Provide ad hoc financial analysis, tracking reports, documentation, and finance-related administrative support as assigned by the Finance and Admin Lead. Coordinate information requests across teams, maintain clear records of actions and decisions, and support practical improvements to finance and AP workflows.

Compliance & Audit Support

  • Coordinate ongoing internal and external audit requests under the direction of the Finance and Admin Lead. Prepare audit schedules, reconciliations, cost breakdowns, transaction listings, and supporting documentation; maintain a request tracker; and follow up with relevant teams to resolve missing evidence and outstanding queries within agreed deadlines.
  • Perform periodic reviews of project transactions to assess compliance with approval limits, delegated authorities, procurement procedures, and financial control requirements.
  • Support the implementation of improved internal controls, standard operating procedures, and documentation requirements to reduce audit findings and recurring control deficiencies.

Qualifications:
