Welcome to BITS Ltd

We focus on delivering Value Added IT Services and cost effective Solutions to companies of all sizes across most industries.

We have the experience, knowledge and skills to assist and guide those companies who have no internal IT department as well as working with companies who have their own internal IT resources but who have limited or no Project Management skills available. We also work closely with large enterprises who need additional resources in key areas or for specific projects.
