Interim Cost Accounting Manager

London – Hybrid (1-2 days per week)

6-Month Contract | £500-600 per day | Outside IR35

We Do Group is supporting a fast growing high-tech manufacturing group to appoint an experienced Interim Cost Accounting Manager for an initial six-month contract.

This is a high-impact assignment offering the opportunity to shape and improve the organisation's cost accounting framework within a growing, technology-led manufacturing business.

Reporting directly to the Group Financial Controller, you'll be brought in as the subject matter expert to review, redesign and embed best practice across cost accounting, inventory and COGS reporting.

The brief is intentionally broad. We're looking for someone who can quickly assess the current state, identify opportunities for improvement and deliver practical solutions that leave the business in a stronger position.

If you enjoy rolling your sleeves up, solving problems and building robust finance processes from the ground up, we'd love to hear from you.

Wish List

• Fully qualified accountant (ACA, ACCA or CIMA)
• Strong manufacturing finance background
• Proven expertise in cost accounting, inventory accounting and/or COGS reporting
• Experience improving finance processes within fast-paced or changing environments
• Strong systems knowledge with the ability to interrogate and improve reporting
• Comfortable operating autonomously and influencing stakeholders across finance and operations
• Available to start immediately or at short notice (1 week notice max)

The Role

The successful Interim Cost Accounting Manager will be responsible for:

• Reviewing and enhancing the existing cost accounting framework
• Improving the accuracy and robustness of COGS reporting
• Reviewing inventory accounting processes, controls and valuation methodologies
• Identifying process inefficiencies and implementing practical improvements
• Supporting finance and operational teams with improved costing methodologies
• Ensuring inventory movements and manufacturing costs are accurately reflected within financial reporting
• Developing meaningful reporting and analysis to improve operational decision making
• Strengthening financial controls across inventory and manufacturing accounting
• Partnering with key stakeholders across finance, operations and supply chain
• Providing recommendations that create a scalable platform for future growth

Your Profile

We're looking for an experienced interim finance professional who has built their career within manufacturing environments and genuinely understands the complexities of cost accounting.

You'll be commercially minded, highly analytical and comfortable operating with minimal direction, quickly establishing credibility with senior stakeholders.

Most importantly, you'll enjoy bringing structure to ambiguity, identifying practical improvements and delivering tangible results within a relatively short timeframe.

This is an ideal assignment for someone who enjoys solving complex accounting challenges and making a visible impact from day one.
