O2 Systems Ltd designs, publishes and maintains bespoke business software and provides senior IT consultancy — from first architecture sketch to the systems your team relies on every day.
Each line of business below corresponds to our registered SIC activity — we don't outsource between them, the same engineers carry a project from spec to support.
Productised software we own, license and maintain — built once, shipped to many.
Business and domestic applications built around how your operation actually works.
Independent architecture, security and strategy advice from senior consultants.
Ongoing support, hosting and infrastructure care once your system is live.
No black box. You know what stage your project is at and who owns it, every step.
We sit with your team to map the real workflow, not the assumed one, and agree what "done" looks like.
Data model, integrations and interface laid out before a line of production code is written.
Working software in your hands every fortnight, so direction can change before cost does.
We stay on as the team who built it — monitoring, fixing and extending the system post-launch.
A short call is usually enough for us to tell you whether this is a build, a consultancy engagement, or both.
