SAP is a software that helps large profile companies better than Tally. There are lot other softwares too for eg - from oracle and others

there are many ERP softwares that rival or are better than Tally ERP 9. But do remember that Tally ERP 9 is in many ways superior to those softwares. Tally ERP 9's inventory module is the strongest I have come across. The other software are SAGE Peachtree series (US, UK version) that include the popular SAGE 50 and SAGE 100 ERP Solutions. Then we have the amazingly powerful cloud and desktop based INTUIT QuickBooks series. It has Pro, Premier and Enterprise Solution flavours in Desktop version. And Simple Start, Essentials and Plus in the Online or Cloud-based version. The certification for QuickBooks Online is for FREE. If you pass that exam you can become a CLOUD PRO-ADVISOR and advertise yourself for practice (for free) in the US and Canada and many other countries.
Apart from these popular ERPs we have TRAVERSE ERP solution. another great ERP Software.

If you need more information about these software let me know. I am already enrolled in the QuickBooks Cloud Pro-Advisor Programme. Its totally FREE.
