Our Services and Solutions
We specialize in providing cost effective, leading edge solutions to Small and Medium sized Enterprises (SME’s). We are the complete SME IT solution specialists.

Our Competencies include:

Service Pricing

We offer ‘Solution Pricing’ as opposed to hourly rates, as we find this is preferred by our clients who like to know ‘up front’ what they will be charged for a particular solution. We work with clients to come up with a schedule of prices based upon specific needs. This schedule is reviewed on a regular basis and amended, if necessary, upon mutual agreement.
