Interim Finance Systems & Process Improvement Lead

Interim Finance Systems & Process Improvement Lead

Financial Controller level or just below | 3–6 month contract | 5 days per week | Runcorn / hybrid

The role

We're looking for a hands-on interim finance professional who can get under the bonnet of our finance function, work out what's creaking, and build the fix.

This is a delivery role, not an advisory one . We want someone who can diagnose the gaps, roll up their sleeves and improve the underlying systems and processes themselves.

We run NetSuite , so strong practical knowledge of the platform is essential.

Your first 4–8 weeks

You'll have two big priorities:

• Treasury and cashflow modelling & reporting — including a likely rebuild of our existing cashflow forecasting model
• AR and AP process improvement — an end-to-end review covering collections, approvals, controls and the impact on month-end

In short: find the friction, fix the process, make the numbers better.

The broader mission

Once the immediate priorities are under control, you'll also:

• Identify and implement opportunities to automate manual and repetitive finance tasks, making full use of NetSuite functionality
• Support the development of financial and non-financial reporting, including KPIs and management reporting
• Document the improved processes so the permanent team can pick things up without needing a decoder ring
• Leave the finance function in a better, cleaner and more scalable place than you found it

What we're looking for

You'll be a qualified accountant (ACA/ACCA/CIMA) with FC-level or senior finance manager experience, plus:

• Strong NetSuite experience , including configuration and reporting — not simply end-user experience
• Advanced financial modelling skills, particularly cashflow and treasury forecasting
• A demonstrable track record of finance process improvement and automation
• Experience working in a business of similar size and complexity
• The ability to work independently, move quickly and get things done without needing extensive hand-holding
• A practical mindset: you're as comfortable improving a process as you are explaining why it needs improving

The essentials

Contract: 3–6 months

Location: Runcorn / hybrid

Working pattern: 5 days per week

Level: Financial Controller / Senior Finance Manager

Rate: £450–£650 per day, outside IR35
