Mainly Small business operating alone for their bookkeeping and reconcialation as its does the great job for the small business. Large buisness use SAP due to incorporating their other Subsidiaries, maitiaining stocks, producing management accountsand SAP is great way for internal transaction interaction for this purpose. 

Sage opt for all kind of business...and it can be customized according to the requirement of the business to maintain the book keeping effectively...but for small business its enough to maintain by quickbooks, peachtree or equilant where ERP is not neccessary.
