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.

If you run your small business out of your hat, their FAQ and manual can tell you more about how it works.
