For IT teams and technical evaluators

One system,
deployed separately for each organisation

CJN Auto and CJN Projects share one codebase, but every organisation gets its own installation — separate database, own domain, only the modules it uses. This page answers what IT usually asks before approving.

Deployment and isolation

Each organisation gets its own building, not a room in ours

A separate PostgreSQL database per organisation — nobody’s data sits in anyone else’s
Your own domain, e.g. ops.your-company.com
Only enabled modules exist — unused menus and APIs are simply absent
Hosted on cloud we operate, or inside your own cloud account
Every installation receives updates from the same codebase on a scheduled cadence

Security and auditability

Auditable from the database up

Row-level security enforced in the database on every table, not only in the UI
Audit log on every table — who changed what, when
Financial documents are immutable once issued; replacements carry a reason; numbering is sequential and countable
PDPA consent records and data-subject requests are part of the core
Role-based access defined per organisation, with API clients separate from users

Integrations

Open to other systems from day one

REST API with OpenAPI documentation generated from the code
Webhooks for key events — booking confirmed, invoice issued, payment received
LINE Official Account for lead capture and notifications
Leads from the brand’s own website, de-duplicated
Excel import at onboarding; exports to accounting software or head-office systems
