Enterprise Application Development
Large-scale systems that hold up under real organisational load — permissions, audit, integration and volume.
Enterprise systems fail for organisational reasons more often than technical ones. Permissions do not match how approval actually works, the audit trail cannot answer the question an auditor asks, or an integration nobody documented breaks quietly at month end.
We build line-of-business applications that hold up under real organisational load: thousands of users, layered permissions, regulated audit requirements and a decade of integrations that all have to keep working.
How we approach it
We start with the org chart and the compliance obligations, not the feature list. Access control, audit and reporting are designed first, because retrofitting them into a finished application is where enterprise projects go over budget.
Why this matters
-
Permissions that match reality
Role and attribute-based access modelled on how your organisation actually delegates authority.
-
Audit that answers questions
Every material change recorded with actor, timestamp and before-and-after state.
-
Integrates with what you have
ERP, finance, HR and identity systems connected properly rather than through overnight exports.
-
Survives a reorganisation
Configuration rather than code changes when teams, regions or approval chains move.
What is included
-
Role and permission modelling
Fine-grained authorisation with delegation, deputies and time-bound access.
-
Full audit logging
Immutable activity history with export for internal audit and regulators.
-
Single sign-on
Entra ID, Okta or your existing identity provider, with SCIM provisioning.
-
Reporting and export
Operational reporting built in, plus a clean data feed to your warehouse.
How we deliver it
-
01
Discover
Workshops with the people who will use it, a map of the systems the application has to fit alongside, and written agreement on what success looks like.
-
02
Design
Architecture, data model and interface prototypes, reviewed with your team before any production code is written.
-
03
Build
Two-week increments with a demo environment you can use throughout, so the roadmap stays open to change.
-
04
Harden
Load testing, security review, accessibility audit and the operational tooling needed to go live safely.
-
05
Operate
Support, iteration and a documented handover whenever you decide to run it in-house.
What you receive
- Permission and audit model signed off with your compliance team
- Production application and infrastructure as code
- Integration contracts with every connected system
- Automated test suite and CI/CD pipeline
- Administrator documentation and team training
What clients say about this work
“We had spent two years and a lot of money failing to replace our claims platform. Vertexa spent three weeks understanding why, then delivered in increments we could actually verify. Eight months later it is live and our cycle time has halved.”
