We are partnering with a PE-backed SaaS business seeking an experienced Interim FP&A Consultant to support the business through an upcoming exit.

The business generates approximately £30m in revenue and is entering a critical phase under private equity ownership, with a requirement for additional FP&A capability as it prepares for a transaction. The successful candidate will work closely with the CFO and senior leadership team, providing the modelling, forecasting and commercial analysis needed to support both ongoing performance and the exit process.

This is a hands-on mandate requiring someone with strong financial modelling and commercial FP&A capability, who can operate effectively with complex data and provide clear insight across SaaS performance. The role will cover budgeting, forecasting, short-term cash flow, scenario analysis and transaction support, with exposure to the wider diligence process.

The successful candidate will be comfortable working in a fast-paced, PE-backed environment, able to get into the detail quickly and operate effectively where data, reporting and processes are still developing.

The role will require 2 days per week in the London office, with an immediate start preferred.

Key Responsibilities

• Support the CFO and senior leadership team through the exit and financial due diligence process.
• Analyse key SaaS metrics including ARR, MRR, churn, LTV and CAC, translating performance into clear commercial insight.
• Work with large and complex datasets to identify trends, risks and opportunities across the business.
• Partner with Sales, Marketing and other commercial teams to improve forecasting and performance analysis.
• Prepare scenario analysis and financial information for senior management, investors and external advisers.
• Improve existing FP&A reporting, data quality and forecasting processes.
• Support the continued development and automation of reporting across Excel, Salesforce, BI and ERP environments.

Candidate Profile

We're keen to speak with individuals who can demonstrate:

• Fully qualified accountant (ACA, ACCA or CIMA) is essential.
• Strong hands-on FP&A and financial modelling experience.
• Previous experience within a PE-backed SaaS/software business is essential.
• Strong understanding of SaaS metrics, recurring revenue models and associated commercial drivers.
• Advanced Excel and financial modelling capability, including scenario analysis, budgeting and forecasting.
• Strong cash flow forecasting, ideally including short-term cash flow modelling.
• Previous exposure to a transaction, exit, M&A or due diligence process would be highly advantageous.
• Experience working with complex datasets and translating financial information into clear commercial insight.
• Exposure to Salesforce, Power BI and NetSuite would be advantageous.
• A proven track record as an interim/contractor, with the ability to get up to speed quickly and work autonomously.
• Ability to operate effectively within a fast-paced and developing finance environment.
• Ability to work 2 days per week in the London office.
• Immediate availability or availability at very short notice.
