I will be brief. If you have SAP ECC 6.0 SPS 15 or higher you can run SAP Fiori and its for free. If not you don’t need to do a costly upgrade, you can run OpenUI5 which is maintained by SAP and which is also free and can be made to look and behave like SAP Fiori ( including on your phone or tablet ).

Any questions please shoot a mail on info@roitech.biz.
