Role Overview

We are seeking an O2C (AR) Lead to own the end-to-end O2C process, including upstream data quality, invoice timeliness, and cash collection outcomes. The AR Lead will not only oversee billing and collections operations, but will also act as the commercial gatekeeper, enforcing data completeness standards, preventing repeat billing issues, and driving sustainable improvements to cash conversion. The ideal candidate is hands-on, commercially minded, tech-savvy, and confident in enforcing controls and accountability across functions.

In addition to leading the AR and O2C function, this role will support the Finance Lead in overseeing the accuracy and integrity of the main company's financial statements. The AR Lead will play a key role in ensuring alignment between AR sub-ledgers and the General Ledger, supporting month-end close, revenue recognition accuracy, and audit readiness. This position is ideal for a hands-on finance professional who is commercially minded, tech-savvy, and comfortable operating across both operational finance and core accounting controls.

Key Responsibilities

1. Order-to-Cash Ownership & Governance
- Own the full Order-to-Cash lifecycle, from Sales Order (SO) readiness to invoice issuance and cash collection.
- Act as the commercial and data-quality gate prior to invoicing.
- Define and enforce mandatory SO completeness standards (data fields, attachments, approvals).
- Reject incomplete or inaccurate SOs and return them to the accountable Operations owner.
- Establish and enforce SLAs for SO submission, approvals, and corrections.
- Escalate repeat breaches or delays with data-driven reporting to Finance leadership.

2. AR Operations & Invoicing
- Manage the complete invoicing cycle, ensuring invoices are created only from approved and complete SOs.
- Ensure invoices comply with client-specific portal submission requirements, documentation needs, and formatting standards.
- Review timesheets, POs, and Statements of Work for commercial and billing readiness, not just completeness.
- Identify root causes of invoicing delays or errors and implement preventive controls, not just corrective actions.
- Maintain accurate AR records and audit trails to support compliance and audits.

3. Collections & Cash Conversion
- Own AR ageing, DSO, and cash collection outcomes.
- Actively pursue collections, including direct follow-ups and calls with client finance teams, where appropriate.
- Maintain a structured log of overdue invoices, disputes, and root causes.
- Escalate non-payment issues arising from operational gaps or client disputes with clear recommendations.
- Partner with Operations only for genuine commercial disputes, not for routine collections.

4. Leadership, Controls & Team Discipline
- Lead and develop the AR team to operate within defined controls and standards.
- Ensure AR staff do not compensate for upstream data gaps or bypass controls to meet deadlines.
- Implement SOPs that prioritise accuracy, prevention, and accountability over speed.
- Review and approve exception handling, assumptions, or risk-based invoicing decisions.

5. High-Risk & Non-Standard Billing Oversight
- Provide senior oversight for ad-hoc, overseas, EP, or high-risk jobs.
- Ensure costing completeness and commercial clarity before invoicing.
- Prioritise such invoices to reduce founder escalation and client dissatisfaction.

6. Process Improvement, Automation & Digitalisation
- Redesign AR and O2C workflows to eliminate repeat issues and manual rework.
- Partner with Finance Systems / Digital teams to implement automation, workflows, and validation rules.
- Drive upstream data accuracy by embedding controls at source, not downstream fixes.
- Maintain clear, current documentation for all AR and O2C processes.

7. Cross-Functional Accountability
- Work with Operations and Command Centre to align responsibilities for data accuracy and timeliness.
- Ensure accountability for delays and errors sits with the originating function, not AR.
- Provide management with regular insights on systemic bottlenecks, repeat issues, and cash risks.

Explicit Stop-Doing Principles
The AR Lead is expected to ensure that the AR function:
- Does not create invoices based on verbal instructions.
- Does not correct or reinterpret incomplete operational data.
- Does not absorb repeat upstream errors to protect other functions.

8. GL & Financial Oversight Responsibilities

In addition to leading the Order-to-Cash and AR function, the AR Lead will support the Finance Lead in overseeing the integrity and accuracy of the Company's financial statements. This role acts as a key control partner across AR, GL, and month-end close processes.

8. General Ledger & Financial Statement Oversight

- Act as the Finance Lead's right hand in overseeing the accuracy of the main company's financial statements.

- Review AR-related GL postings to ensure proper revenue recognition, cut-off, and classification.

- Ensure consistency between AR sub-ledger and General Ledger, including timely reconciliation and resolution of variances.

- Review and validate month-end AR accruals, deferred revenue, provisions, and adjustments.

- Support month-end and year-end close activities, ensuring AR and revenue figures are complete, accurate, and audit-ready.

9. Revenue Recognition & Controls

- Ensure revenue is recognised in accordance with contractual terms, service delivery, and accounting standards.

- Review complex or non-standard billing arrangements to assess revenue timing and accounting treatment.

- Partner with Finance leadership to flag revenue risks, unusual trends, or accounting judgement areas.

- Support documentation and justification for management judgement items impacting revenue or receivables.

10. Audit, Compliance & Reporting Support

- Act as a key point of contact for auditors on AR, revenue, and O2C-related matters.

- Prepare AR schedules, reconciliations, ageing reports, and audit support documentation.

- Ensure AR processes and records meet internal control, audit, and regulatory requirements.

- Support implementation and maintenance of finance controls related to receivables and revenue.

11. Cross-Functional Finance Partnership

- Work closely with the GL, AP, and FP&A teams to ensure alignment between operational billing and financial reporting.

- Provide Finance leadership with clear visibility on AR-driven impacts to cash flow, revenue, and working capital.

- Support finance initiatives such as forecasting, cash flow planning, and process improvements impacting AR and revenue.
