SAP Controlling

at its best

How would you like your controlling processes in SAP to finally run smoothly?

HAG Consulting


Our consulting approach is strongly end-to-end driven; we think in terms of business processes, rather than in single modules, and thus help our customers to sustainably optimize processes and exploit the full potential of the SAP system.

We provide comprehensive advisory, conduct high-quality concepts that are ready to realize and also take care of the realization; from the conceptual design until the rollouts. Working in partnership at eye level is always essential. Both medium-sized and large end customers as well as leading strategy and SAP consulting firms rely on our expertise.

Dr Hasan Güler provided us with excellent support in our S/4 HANA project as part of the controlling concept development. Thanks to his proven controlling expertise and his detailed knowledge of the SAP system, he was able to build an effective and high-quality bridge between our existing SAP processes and the new S/4 HANA world. Thanks to the concepts he developed, we are now well prepared for the implementation.

I had the pleasure of working with Hasan from 2016 to 2023 when he served as one of our Lead Consultants for Record-to-Report (R2R). Hasan’s strong process orientation, hands-on approach, and expertise in controlling were instrumental in successfully implementing our requirements into S/4HANA. Hasan consistently delivered good results and I wholeheartedly recommend him for any organization seeking an experienced and results-driven consultant in SAP.
