About Mag. Sermet Karshon-Haider
Sermet Karshon-Haider

Before I focused entirely on SAP consulting, I spent ten years in controlling — in group controlling at a large Austrian company, as Country Controller for Austria and Switzerland, and as investment and production controller at an internationally operating manufacturing company.

This perspective shapes my consulting to this day. I know the questions business users ask, because I used to ask them myself.

Since 2020, I have been supporting companies as a Senior SAP-CO Consultant through S/4HANA implementations, conversions, rollouts, and public cloud projects. I am currently leading the CO workstream for an S/4HANA implementation in the Austrian healthcare sector.

Why work with me

Consulting with substance.

Four things that set my work apart from purely technical SAP consulting.

01

Business and system

Nearly ten years of controlling practice, several of them at group and country level. I've personally owned planning, reporting, budgeting, product costing, and consolidation — before implementing them in SAP.

02

Certified and current

SAP Certified Application Associate for S/4HANA Finance, S/4HANA Management Accounting, and S/4HANA Cloud Public Edition Finance 2023. Additionally, certified accountant (Bilanzbuchhalter).

03

Proven across project types

Greenfield, brownfield/conversion, rollout, public cloud — I've delivered every common S/4 project type multiple times, including four completed conversions and two greenfield implementations.

04

Modern reporting

I replace technically outdated reporting with CDS views, Fiori Embedded Analytics, and custom queries — delivering real-time transparency at the management level.
