“the first truly independent global SAP advisory practice, offering unmatched expertise and insights to guide clients through their transition from ECC.”

Global ERP Advisory is the first truly independent global advisory practice dedicated to SAP clients.

We offer specialised advisory services for SAP clients on ECC needing to transition — whether to S/4HANA, RISE, or alternative platforms.

Global ERP Advisory is led by founders Judith O’Callaghan (visionary ERP thought leader and SAP transformation expert) and Ashley Saltzman (former SAP Head of Commercial Escalations, also known as “the man who defuses bombs”).

We bring together a team of seasoned ERP experts from around the globe, each with over 25 years of experience in the SAP ecosystem.

Global ERP Advisory is here to help you navigate the critical decisions that will shape your transition strategy as the December 31, 2027 deadline for SAP ECC support approaches.

What makes us different?
For a start, we are not a system integrator or an implementation partner.
We are completely independent — we don’t receive funding from any external organisations and do not sell SAP products.
This means we are 100% advisory, with access to the best SAP systems experts worldwide.

Our expertise lies in Phase 0 – the foundational stage before your project begins.

Our Phase 0 Services deliver essential insights and data to build a compelling business case and significantly minimise business risk, ensuring a clear path to a successful transformation.

We answer YOUR questions -

Which SAP pathway is right for us?

What factors do we need to know to make an informed decision?

What steps can we take to address and reduce our business risks and exposure?
