Custom Software Development
Systems built around your operating model, not a vendor’s roadmap
How it is quoted
Priced per scope
Fixed fee agreed in writing before work starts
10–20 weeks to first production release
When off-the-shelf software forces your business to work backwards, we build the system that fits. Acceron designs and engineers bespoke platforms — operations tooling, customer portals, trading systems, workflow engines and internal products — that encode the way your organisation actually works. Every engagement starts with a fixed-price discovery, produces a costed architecture, and delivers working software in two-week increments you can inspect, test and sign off.
Who this is for
- Operations leaders running critical processes on spreadsheets and email
- Scale-ups that have outgrown a no-code stack or a single monolith
- Enterprises replacing an unsupported legacy system without halting trade
- Product teams needing a senior engineering pod that ships from week one
Problems it solves
- Manual handoffs and re-keying between disconnected systems
- Legacy applications nobody can safely change or upgrade
- Process bottlenecks that only scale by adding headcount
- Reporting built from exports, so decisions run a week behind reality
- Vendor lock-in and licence costs that rise faster than the value delivered
How we deliver it
Discovery sprint
Two weeks of process mapping, stakeholder interviews and technical due diligence, ending in a costed backlog and architecture decision record.
Architecture & design
Domain model, integration contracts, security model, non-functional targets and clickable prototype signed off before a line of production code.
Incremental build
Two-week sprints with demo, test evidence and deployable increment. You see progress fortnightly, not at the end.
Assurance
Automated regression suite, load testing to agreed thresholds, accessibility audit and independent security review.
Launch & migration
Phased cutover with data migration rehearsals, rollback plan and hypercare cover for the first 30 days.
Evolve
Roadmap reviews each quarter, with a standing engineering allocation so improvements never queue behind procurement.
What you receive
- Production application with source code and full IP assignment

The business benefit
- Process time cut, not shifted
- Clients typically remove 30–60% of manual handling from the workflows we automate, verified against a baseline we measure in discovery.
- You own everything
- Full intellectual property assignment on final payment, including source code, infrastructure definitions and documentation.
- Costs you can plan around
- Fixed-price phases with a written change-control process. No open-ended time and materials.
- Built to be handed over
- Documented, tested and conventional by design, so your team — or any other supplier — can take it forward.
