About

Nash & Co is Lee Nash.

A chartered management accountant who builds the systems — finance and technology in one pair of hands.

I'm a CIMA-qualified (ACMA, CGMA) finance systems & transformation lead and Dynamics 365 Business Central implementation specialist with 20+ years across finance, systems and data.

I started in finance — treasury, analysis and management accounting at the likes of PwC, BAE Systems and Victrex — then moved into the systems that finance teams depend on. Over the last decade I've led end-to-end Business Central and NAV implementations, finance transformations and consolidation projects across pharmaceutical, healthcare, public sector, housing, utilities, engineering and manufacturing clients.

What makes Nash & Co different is simple: you get one senior person who understands both the debits and the data. I can map your month-end, design the chart of accounts, configure Business Central across every module, write the AL and automation, build the consolidation in TM1 or Konsolidator, and deliver the Power BI and Jet reporting on top — so the build and the numbers actually line up.

No juniors, no handoffs, no jargon. Just straight-talking, hands-on delivery from someone who's accountable for the result.

Let's talk about your finance systems.

Whether it's a new build, a rescue, or just better reporting — start with a conversation.
