Can we really take SAP Business One (B1)… As a mid-market Enterprise Resource Planning (ERP) in countries like INDIA, A short description please?

Ofcourse we can, SAP B1 is developed for mid-market and SME as well, who intends to leverage on the robust features of an SAP ERP, but has limited budget. Many organisations are on SAP B1 and there are several implementation partners that can comfortable handle the implementation and support. The implementation time frame for SAP B1 is way shorter that the ALL-in-one. 

Absolutely. SAP B1 is a robust ERP and we have experience of it supporting businesses with thousands of locations and users. An added advantage is the price point which, as opposed to All in one and R3, competes very well with the likes of AX etc. Since you are in India I would also add that the proliferation of SAP B1 partners in the country also means you can probably get services and support at much more cost-effective prices than elsewhere in the globe.
