Free business management cloud service, SohoOS
http://www.sohoos.com/welcome/what-is-sohoos/solution explains a new, free, business service providing accounting and CRM (Customer Relations Management) with billing, receivables and payables, plus document, project and inventory management, which also works from a smartphone.
PC Magazine's review noted: SohoOS sports two tabs, Tools and Communication, which carry costs. Users can either pay per usage or sign up for a "VIP" membership that loads extra cash, direct support, and training. If you're looking to distribute bulk e-mails or SMS messages, host a VOIP conference, or send a fax, you can pay to play through the Communication tab.
