Interim Finance Systems Implementation PM — NetSuite Rollout — 6 Months — Remote — Outside IR35

We're looking for an experienced Interim Finance Systems Implementation PM to lead a NetSuite implementation for a business undergoing a significant finance systems transformation, working closely with an internal finance team product owner.

The role:

You'll manage two parallel workstreams:

An external implementation agency delivering the core NetSuite build and configuration
An internal engineering team rebuilding billing processes in Salesforce and building the NetSuite integration

This is a hands-on delivery role. You'll need to bring structure to a programme that's still early in its discovery phase on the billing side, keep a third-party agency accountable to scope and cost, and make sure both workstreams land in sync.

Timeline:

Start: September (ASAP)
Contract length: 6 months, with potential extension
Hard deadline: end of March 2027, ahead of a regulatory billing change taking effect in April 2027

What we're looking for:

Has led more than one finance systems replacement (sector agnostic)
Direct experience with billing process redesign
Strong track record managing external implementation agencies, holding them to scope and pace without derailing the relationship
Comfortable operating across both finance and technology stakeholders
Collaborative delivery style; able to bring people with you rather than push through, so that risks and blockers surface early rather than late
