Tell us about your project

Custom enterprise software development that holds up to scrutiny.

Governance you can see.

Larger organisations need to approve what gets built and when. We're transparent about scope, timeline and cost, so you know what's happening at every stage.

Security designed in.

Security is a design input, not a checklist added at the end. Encrypted data access, secure sign-in, role-based access and audit logging are built in from the start.

Legacy systems kept running.

You've built something that works. We connect to the systems you already run and modernise in phases, so nothing stops moving while the new system comes online.

What we build

Enterprise custom software development for established organisations.

Legacy systems, modernised without losing what works.

Legacy systems, modernised without losing what works.

Your system needs to do more: integrate with new platforms, handle new volumes, or move to a team without the same institutional knowledge. We make that change safely.

New platforms

Integrations with new platforms added to the system you have, without rebuilding the parts that already work.

New volumes

Systems reworked to keep up as users, data and transactions grow, so performance holds as usage climbs.

Phased replacement

The replacement is built in phases alongside the old system, so nothing stops while the new one comes online.

Know where the risk is

We review architecture, code quality, security posture and scalability first, so changes start from the facts.

When your operations outgrow your tools.

When your operations outgrow your tools.

Manual workflows, spreadsheets and disconnected tools slow larger teams down. We build software that fits the way your team actually works, not the way a vendor assumes it does.

Field and multi-site teams

Offline-ready apps for inspectors and site staff, so work carries on at warehouses and field sites.

Head office visibility

One central view of what's happening across every site and team, without chasing updates from the field.

Audit-ready records

Records and reporting built into the system as the work happens, not assembled after the fact.

Access by role

Role-based access, so contractors, employees and site managers each see only what they need.

Integration with the systems you already run.

Integration with the systems you already run.

Registries, fleet and lease platforms, payroll and back-office systems. We build the API layer that keeps data in sync, so your teams stop re-keying it between systems.

Explore API development and integration
Core registry sync

Real-time data sync with a share registry's core platform and the back-office systems around it.

Fleet and lease systems

An API that carries inspection data from a field app into internal fleet and lease management systems.

Payroll, leasing and claims

Payroll, leasing and claims kept in sync through a Catch-e integration, across every system that needs it.

No more re-keying

Data moves between systems automatically, so your team stops entering the same details twice.

Internal opportunities that need an external build partner.

Internal opportunities that need an external build partner.

Sometimes the opportunity is clear but the internal capability to build it isn't. We step in as the technical partner, from discovery through to delivery.

Discovery to delivery

One technical partner from the first discovery workshop through design and build to launch.

Web and mobile

Native iOS and Android apps, with the web platform and APIs that sit behind them.

Secure by default

Biometric sign-in and encrypted data access where the product handles sensitive information.

Built to hand over

Tested, maintainable code your team can own once it's live, or we stay on to support it.

How we work

Ready for your IT, security and procurement teams.

Discovery before code.

We start with your constraints, your stakeholders and your existing systems, and what success looks like. Your IT and security people are part of that from day one.

Access and audit built in.

Role-based access control and audit logging come built in, so you can see who did what and when. Records stay audit-ready, not assembled after the fact.

Confidential from the start.

We can provide a mutual NDA that protects your IP and ours, so your team can share systems, data and plans with us safely before any work starts.

Handover your team can own.

We hand over tested, maintainable code and the knowledge your team needs to own it. Or we stay on for support and maintenance, tailored to what you need.

Common questions

Building software for organisations with more users, more systems and more to get right. It has to fit your governance, connect to what you already run and stay maintainable by your team.

We treat security as a design input, not a checklist added at the end. Encrypted data access, secure sign-in, role-based access and audit logging are built in where the system needs them.

Yes. We start by understanding what the existing system does well, then integrate with it or replace it in phases, so nothing stops moving while the new system comes online.

Your brief and any supplier requirements you have. We'll give you a detailed estimate, free of charge, and work through your requirements with you before any work starts.

Every project is different. Send us your brief and we'll give you a detailed estimate, free of charge.

There are two options. You can move into support and maintenance, which we can manage, or keep developing while we support the current version. Support is tailored to what you need.

Yes. Sentia is based in Sydney and has built software for startups through to enterprise since 2006, with our Zagreb team adding delivery capacity.
