Our new premises opened in 2010 in Newcastle-under-Lyme,
Staffordshire. We serve the UK's not-for-profit organisations.

Our people make us great!

We are proud to be a UK based company who does not employ 3rd parties or contractors to complete any part of our projects.  All work completed by us is done so by 3Si employed members of staff based at our Head Office in North Staffordshire.

Our long standing team of Implementation Consultants, project management, training and HelpDesk specialists have earned a reputation for delivering service excellence, based on decades of involvement in the non-profit sector and demonstrable empathy for the issues that such organisations face. It is this dedication that attracted customers such as the British Printing Industries Federation, the Engineering Construction Industry Association and NFU. 

Our commitment to providing software solutions that best-fit customers; requirements on time and within budget results in excellent feedback every time we undertake a customer satisfaction survey. Flexible, understanding, professional, intuitive and cost-effective are all terms our customers have used to describe the service they have received.
