About Us
Software people who answer the phone
Based in Bicester, Oxfordshire, working across the UK. We build systems that earn their keep and we tell you when you do not need us.
Celsius Software exists because too much business software is sold on a promise and delivered as a disappointment. We do the opposite: quote an honest date, build something your staff will actually use, and prove the value in hours saved or money made. If a system cannot show that, it is an expensive screensaver and we will say so.
What we believe
Four principles, no poster required
Under-promise, over-deliver
We would rather quote you a boring, honest date and beat it than sell you a fantasy and miss it by a quarter.
Technology must pay its way
If a system cannot show you hours saved or money made, it is an expensive screensaver. We measure it.
Fast, agile platforms
We build on platforms that let us ship in weeks, not financial years, so you stay ahead of the people who are still in workshops.
Real people, real answers
No ticket purgatory, no call maze. You ring, a human who knows your system answers.
In the community
Congratulations Boys!
Proud to support the next generation of football talent in Bicester, this junior football team is proudly sponsored by Celsius Software. More than just a team, they represent the energy, teamwork and community spirit that make grassroots football so special. We’re delighted to play a small part in helping these young players enjoy the game, develop their skills and, most importantly, have fun together.
