If you want a full business management suite including accounting, operations and customer relationship management, and you have a single legal entity then your product is NetSuite.
Look at NetSuite OneWorld if you have multiple legal entities and again you want to manage the entire business in a single integrated suite.
If you want to start with CRM, then investigate NetSuite CRM+. You can use CRM+ and then upgrade later to either NetSuite or OneWorld.
If you do not need CRM, but you want NetSuite's robust ERP functionality, then take a look at NetSuite Financials.
Regardless of the software product you choose, you have access to SuiteFlow to build your organization's unique business processes.
