Job Description

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
