The prerequisites for any business nowadays are the IT department and the PBX. In the modern electronic age no business can operate without them. Ironically all corporate decision-making and management actions have to be conducted where these facilities are available, namely the corporate office. In other words one does not have the freedom to conduct one’s business from just any place one likes. This static business environment has changed with SaaS and VoIP based services.

Basing the IT infrastructure in software as a service (SaaS) could help businesses operate with lower costs and help them grow. The SaaS model has already becoming popular with many software companies and application providers offering human resources, accounting, procurement, billing, customer relationship management (CRM), sales and marketing, enterprise resource planning (ERP), and business intelligence (BI) services. With SaaS based services, the job of installing and maintaining an application, monitoring reliability, ensuring high availability, etc., are all handled by the provider. SaaS users do not have to pay for hardware, installation and maintenance charges, software licensing charges and the cost of IT infrastructure. SaaS offers pay-as-you-use pricing that allows organizations to use cutting-edge technology. Businesses now have a choice of hosted services at their disposal, only to be accessed through a web browser and a secure internet connection. Because the service provider hosts both the application and the data, the end user is free to use the service from anywhere.

Hosted VoIP service is Voice Over Internet Service that is provided by a third party for businesses with any number of phone extensions. All calls are transported over the Internet, and telephone functions such as voice mail, call routing and call forwarding are performed on the provider’s computers. Administration is usually handled via a Web interface. The clients make and receive calls, check voice messages online, filter incoming calls, add new employees to the system in minutes, etc. Some of the major advantages of hosted VoIP services are similar to those of SaaS based services, such as, lower initial capital outlay as no VoIP hardware or software purchasing cost has to be incurred, client’s ability to increase and decrease capacity in accordance with business requirements, clients enjoy access to the latest technology and services are contracted and based on monthly charges or fixed flat-rate billing. Like Saas, the user can access the service from any location.

These services have truly changed the way businesses can be conducted as one is no more tied down to the corporate office for business information and communication.
