Freelance Financial/Cost Controller A-Z (Accounting Background)

Freelance Financial Controller (Accounting Background)

What the Project Is About

This freelance mission supports a corporate finance team within the Energy industry during a period of operational intensity and investment focus. The Financial Controller will take full ownership of end-to-end accounting and controlling activities, with a strong emphasis on P&L accuracy, revenue recognition linked to invoicing, and CAPEX tracking. The role sits at corporate level and acts as a key financial gatekeeper, ensuring costs and investments are booked correctly, challenged where needed, and fully audit-ready. This is a hands-on, A–Z controlling assignment rather than a managerial oversight role.

Day-to-Day Responsibilities

• Own the full general accounting and controlling cycle from A to Z

• Prepare, analyze, and explain P&L results, with a strong focus on revenue recognition tied to invoicing

• Act as corporate controller for CAPEX: monitoring, follow-up, capitalization, and variance analysis

• Code and process invoices accurately through PO flows, ensuring correct cost allocation and compliance

• Book costs in the correct accounts and cost centers, maintaining clean and reliable financial data

• Perform follow-up on open CAPEX items and challenge internal stakeholders on budget usage

• Liaise with suppliers regarding invoicing discrepancies and financial clarifications

• Act as a critical financial partner by challenging internal teams on cost control and financial logic

• Support and coordinate internal and external audits, ensuring documentation and processes are compliant

• Contribute to month-end and period-end closings, reconciliations, and reporting packs
