Zoho
Zoho is the best small business CRM software for several reasons, although the primary factor making Zoho stick out from the proverbial crowd is its high level of customizability. Business owners or managers have the power, as long as Zoho's by their side, to build their own application using Zoho's "Creator" application. "Cliq" is the CRM system's instant messaging application, keeping varios communications separate, automatically using PGP to encrypt certain or all conversations, and allowing users to import accounts from all over the Internet. Bring together email domain names and individual accounts using the "Mail" app, banishing the evils of logging in and back out of multiple email accounts. Zoho even saves information regarding financial statement creation and paying taxes, reducing the risk of not paying on time, in full, or not being able to back your claims up in the unlikely-yet-possible event of audit. Trust Zoho to get ahead with customers.
