Interim VAT & Financial Operations Specialist (Outside IR35)

OakRock is supporting a medium-sized business in recruiting an experienced VAT specialist to help design and embed a robust partial exemption process on a project basis, while also strengthening billing, invoicing and collections across a portfolio of customers.

This is a hands‑on, operational role for someone who enjoys building structure in complex, evolving environments and acting as the in‑house VAT expert.

The role

You’ll take ownership of:

• Designing and implementing an internal partial exemption VAT process
• Acting as the business's VAT expert, supporting compliance and best practice
• Building and improving billing and invoice processes, including templates and workflows
• Managing invoicing and collections across a portfolio of customers
• Supporting pragmatic, relationship‑led communication with key stakeholders
• Leading an initial data collection and scoping exercise to stabilise inputs
• Helping the wider finance team improve consistency and control in revenue processes

The environment

• Highly operational, varied "finance all‑rounder" role
• Cyclical workload with a significant set‑up phase in the first 2 months
• Hybrid working

What we’re looking for

• Strong VAT experience, specifically partial exemption
• Comfortable operating as a broad finance practitioner / FC‑style support
• Strong stakeholder communication skills
• Pragmatic, hands‑on approach with strong attention to detail
• Ability to bring structure quickly in a complex environment

Once the processes have been set up and key stakeholders are on board, the role will be largely remote working.
