SAP ECC is the core of SAP’s ERP (enterprise resource planning) architecture. It consists in several modules that provide the organizations with great control over their key business processes.

SAP Estimated Cost

SAP Global Market:

Independent Studies Have Shown That Deployment And Maintenance Costs Of A SAP Solution Can Vary Depending On The Organization. For Example, Some Point Out That Because Of The Rigid Model Imposed By SAP Tools, A Lot Of Customization Code To Adapt To The Business Process May Have To Be Developed And Maintained. Some Others Pointed Out That A Return On Investment Could Only Be Obtained When There Was Both A Sufficient Number Of Users And Sufficient Frequency Of Use.

SAP Estimated Cost:

It Is Estimated That “For A Fortune 500 Company, Software, Hardware, And Consulting Costs Can Easily Exceed $100 Million (Around $50 Million To $500 Million). Large Companies Can Also Spend $50 Million To $100 Million On Upgrades. Full Implementation Of All Modules Can Take Years. Midsized Companies (Fewer Than 1,000 Employees) Are More Likely To Spend Around $10 Million To $20 Million At Most, And Small Companies Are Not Likely To Have The Need For A Fully Integrated SAP ERP System Unless They Have The Likelihood Of Becoming Midsized And Then The Same Data Applies As Would A Midsized Company.
