About Us

About Cornerstone Systems Consultancy

Who We Are

Cornerstone Systems Consultancy is a specialist transformation consultancy focused on finance systems, SAP, and data-led change. We support organisations navigating complex transformations, from post-acquisition integration to large-scale SAP programmes, providing experienced leadership, technical expertise, and hands-on delivery where it counts.

How We Work

Our approach is pragmatic, collaborative, and outcomes-focused. We work closely with client teams to understand their operating environment, constraints, and priorities, tailoring our support to each engagement. Whether providing strategic advisory or embedded delivery leadership, we remain hands-on throughout the transformation lifecycle. We bring structure to complexity, clarity to decision-making, and discipline to delivery — ensuring programmes move forward with confidence and control.

What We Do

We help organisations deliver critical finance and SAP transformations that are often high-risk, time-sensitive, and business-critical. Our core services span finance systems transformation, SAP and data migrations, data cleansing and governance, and project and programme management.

"We work at the intersection of finance, systems, and data, solving challenges such as fragmented operating models, complex system landscapes, poor data quality, and delivery risk. Our focus is always on creating stable, scalable solutions that enable accurate reporting, operational efficiency, and long-term business value."

Our Values

At Cornerstone, our values reflect what a cornerstone represents: stability, trust, and strength.

Integrity First

Honest advice, transparent delivery, and accountability at every stage.

Make Things Happen

We are hands-on, proactive, and focused on progress and results.

Do the Right Thing
