Software-as-a-Service (SaaS) seems to be everywhere lately, especially in the CRM space. For small and midsize businesses, SaaS has been a popular option for a number of years; now larger enterprises are beginning to adopt it in meaningful numbers. SaaS is Web-based software purchased on a subscription basis, allowing an organization to shift almost all technological responsibility to its vendor. While SaaS allows -- and even requires -- its customers to configure the software to meet their needs, the leeway for configuration is often limited. SaaS data-conversion tools are typically wizards that enable data import at the rate of tens of thousands of records per job.
