Calculus Software Solutions Ltd, established in 1999 and incorporated in 2000, is a private limited company. Our focus is on delivering software solutions tailored for the electrical retail sector, with most of our clients being independent electrical retailers.
Calculus is located in Uckfield, East Sussex, and provides services across the UK, including Northern Ireland and remote areas like the Scottish Islands.


Our main offering is NCompass, an EPOS and business management software tailored specifically for the electrical retail sector. In addition, we provide other products such as our WebPresence ecommerce platform, along with the NCompass Mobile and Warehouse mobile applications.
The system's founder and lead developer brings over 25 years of experience in the electrical retail industry, having utilised the NCompass system first-hand. This expertise enables Calculus to deliver exceptional customization for the electrical retail market. Our support team is composed of individuals with significant industry experience, including practical use of NCompass in real-world settings. Furthermore, all support staff undergo training that includes time spent on-site with actual retailers.
Calculus goes beyond simply enhancing the current operations of retailers; it also empowers them to advance their businesses into the future.
We equip management with robust reporting tools that enable them to identify trends, strategise for the future, and track the effectiveness of their plans.
Our eCommerce solutions enable retailers to broaden their sales channels beyond traditional physical stores, allowing them to expand at a pace that suits their needs, with the option to scale up to a nationwide or international presence if desired.
By offering our system in a modular format, we facilitate organic growth for retailers over time, ensuring that each step remains cost-effective.








Since founding Calculus Software Solutions in 2000, I have been determined that will always deliver the best possible systems -- best for usability; best at improving efficiency; best at empowering you to provide the best possible service to your customer.
My background working in electrical retail gives me and insight into what really matters both on the shop floor and in the back office, and this drives our strategy for the improvement of NCompass. We don't develop new features just because we can -- we base our development on the wishes of our users, all the time working to combine the best practices from across the industry.
I guarantee that NCompass Advanced Retail is simply the best system for your business.
