S/4HANA ERP & Finance.
SAP S/4HANA is more than just another new release. SAP’s new business suite brings about so many changes and new functionalities that have the power to transform your business. Through 25 years of guiding our clients in their SAP implementations, we have gained the experience and expertise to make your move to S/4HANA a success.
What S/4HANA is really about.
The major innovation of S/4HANA is the radical simplification of the data model it is based on. SAP’s new ERP system SAP S/4HANA is based on the in-memory database platform SAP HANA. Through its fast computing capabilities, it provides you with real time results and insights which are essential in today’s networked and speed driven economy. Besides that, it comes up with renewed applications, analytics and the modern user interface SAP Fiori. One major shift is that important SAP applications like TM and EWM are integrated parts of one single system.
SAP S/4HANA can modify all critical enterprise functions ranging from finance and supply chain all the way to customer service and marketing. Through it, businesses are able to transact, analyze and predict in real time in a world that remains continuously unpredictable.

Your path to S/4HANA.
We see switching to SAP’s new business suite SAP S/4HANA not as an aspiration, but a necessity. It’s not a question of “if” but of “when” and “how” to do the migration. Success requires an organization to not only implement or migrate to a new platform, but to decide on the best-fit deployment option for their unique business. Whether it is an on-premise deployment, with altered infrastructure to handle exponential growth but still enabled for quick innovation cycles, whether it is a mature and flexible private cloud deployment with 2 innovation cycles per year or whether it is a next practice public cloud deployment with 4 innovation cycles a year or even be a mix of all 3 options.

Selling high-value items to unknown customers bears a tangible risk of a shortfall in payments.
