Three ways to own it — all fully featured.

They differ in deployment and ownership, not in features.

DEPLOYMENT ARCHITECTURE

FAQ

Deployment questions.

How long until go-live?+

Depending on scope, typically 9–14 weeks across the 4-step roadmap. More complex projects are estimated during discovery.

Will we lose data migrating from a legacy system?+

The migration process includes cleansing, reconciliation and a parallel run to surface discrepancies before cut-over. Source-data quality is reviewed together with you at the assessment step.

Who owns the source code?+

The platform core belongs to Apus. With source-code handover you receive the business-layer source; SaaS offers an escrow option.

Can we switch models later (SaaS → On-premise)?+

Yes. You can move between models; scope & cost are defined by the specific contract.

How much downtime at go-live?+

Minimal. Thanks to parallel run and planned cut-over, operational disruption is kept to a minimum.

Choose the model that fits you.

The Apus team advises on the deployment & ownership model for your needs.
