Celsius Software
Business Systems Built to Fit Your Business, Not the Other Way Round
From web platforms to payroll, stock to fleet — 25+ years building UK business software that actually gets used.
Every business runs on systems, and most of them are held together with spreadsheets, workarounds and a colleague who 'just knows how it works'. Celsius Software builds bespoke systems that replace the workarounds properly — web platforms, payroll, time and attendance, document management, project management, stock, workforce, mobile apps and asset management — all built around how your business actually operates, from our team in Bicester, Oxfordshire, serving clients UK-wide for over 25 years.
