What we stand for

Four principles.

  1. Results, not slides.

    Every phase ends with a deliverable you can keep using.

  2. Standard before custom.

    SAP standard and clean core wherever possible; extensions only with a reason.

  3. Your data stays under your control.

    Access only with your authorizations, no copies outside agreed systems.

  4. Finance before technology.

    We start from the close: what has to be right at the end?

Approach

Four phases. Four results.

  1. Phase 1 2–3 weeks

    Assessment

    Result: Decision paper

  2. Phase 2 3–6 weeks

    Design

    Result: Functional design

  3. Phase 3 project-dependent

    Implementation

    Result: Go-live

  4. Phase 4 ongoing

    Operations

    Result: Stable closes

Our approach

We built Numidea Advisory because implementations and conversions in SAP S/4HANA are won or lost in finance – and that is often where people look too late.

Across our core team and partner bench, we combine IFRS and German GAAP (HGB) close, consolidation and S/4HANA Finance & Controlling expertise with principal architects bringing around two decades of experience designing and implementing high-volume SAP Finance and Contract Accounting (FI‑CA) landscapes. Dedicated specialists for SAP Basis, RISE, development and AI complete the team.

Our standard: the same senior architects from initial evaluation through go-live – so at every phase you know where you stand, and your numbers are right at the end.
