SaaS applications are available from any computer or any device, any time, anywhere. Because most people are familiar with using the Internet to find what they need, SaaS apps tend to have high adoption rates, with a lower learning curve.
Lower Initial Costs
SaaS applications are subscription based. No license fees mean lower initial costs. Having the SaaS provider manage the IT infrastructure means lower IT costs for hardware, software, and the people needed to manage it all.
Because the SaaS provider manages all updates and upgrades, there are no patches for customers to download or install. The SaaS provider also manages availability, so there's no need for customers to add hardware, software, or bandwidth as the user base grows.
SaaS vendors with true multitenant architectures can scale indefinitely to meet customer demand. Many SaaS providers also offer customization capabilities to meet specific needs. Plus, many provide APIs that let you integrate with existing ERP systems or other business productivity systems.
No Vendor Lock-in
Because SaaS applications are subscription based, customers can always choose not to renew if they're dissatisfied, making providers more accountable.
No Large Up-Front Investment
With SaaS applications, customers avoid the large initial investment in an IT infrastructure and the day-to-day responsibility of maintaining that infrastructure.
No Maintenance Headaches
SaaS customers all share the same provider infrastructure, which centralizes administration and updates. Plus, integration is simpler because there's no need to support several platforms and multiple versions.
No Steep Learning Curve
SaaS applications are innovating at a rapid rate because developers are focused on what's next rather than on maintaining numerous versions of old code. SaaS vendors use the same technology architecture as the best consumer Web: companies like eBay, Google, and Yahoo!, which enables the same levels of continuous innovation.
