Use software on a subscription basis rather than making an out right purchase.

Software as a Service (SaaS) is a model of software deployment where an application is licensed for use on a per-user, per-month pricing model. 

Several significant benefits arise, including:

• Removes the large upfront fixed costs   associated with traditional software purchase
• There is no need for annual maintenance and upgrade costs as the most current version is always available
• The flexible cost structure is based on a monthly usage where you only pay for what was made available the previous month
• Enables the buyer to share licenses across the organisation rather than the traditional licence per device
• Makes it possible to try software without making large capital investments

As a Microsoft SPLA partner we are able to license Microsoft poroducts on a monthly basis to provide services and hosted application to our customers.
