NetSuite, as the name suggests, is an integrated cloud business software suite. Essentially, it consists of four parts - ERP, CRM, PSA and eCommerce. Netsuite is extremely expensive with an average deployment estimated to be around $40,000 in upfront costs, and monthly fees add up quickly. If you are looking for a free NetSuite alternative, especially if you don't need accounting, Bitrix24 makes a great choice.
