Having enjoyed another successful and profitable year, it was an easy decision to ask the Catalyst Team to upgrade some of our computers, backup facilities and install new software on our systems. As a small but extremely busy International Welding Equipment supply company with the majority of enquiries being generated from our web site, our IT performance is crucial to our business.

Having worked with Catalyst for the past 4 years, we knew they already understood the manic environment they were going to have to work in and made the smooth transition for all the staff, keeping downtime to a minimum whilst completing the work.

As always, small issues occur after any upgrade, often just a software conflict, but as Catalyst offer remote support any minor problems we had were rectified within a matter of hours of our call.

The Staff are friendly, efficient and offer bags of advice. And if they don’t know the answer – they go off and find it. They always respond promptly to our cries for help when our systems go down!

We regularly recommend them for supply and support of all computer needs to local and national contacts.
