How We Build Oracle Fusion Cloud Solutions for Clients

Oracle Fusion Cloud is powerful. It handles financials, procurement, projects, HCM, and supply chain for some of the largest organizations in the world. But extending it? That's where things get complicated.

Oracle offers VBCS and APEX as extension tools, but both require your team to hire developers, manage infrastructure, navigate Oracle's API landscape, and maintain compatibility through quarterly updates. For most Oracle customers, this is a full-time engineering commitment they didn't sign up for.

ERPUX is a different approach. We build the solution. You subscribe to it. This article explains exactly how that works, from the first conversation to a running production application embedded inside your Oracle Fusion instance.

Every engagement starts with a scoping conversation. We need to understand:

• Which Oracle module is involved (GL, AP, AR, Projects, Procurement, etc.)
• What business process isn't working — or doesn't exist yet in Oracle
• Who the end users are and how they interact with Oracle today
• What data sources are needed (REST APIs, BIP reports, SOAP services, ESS jobs)
• Your Oracle environment topology (instances, security model, business units)

This isn't a generic requirements document. We're mapping your problem to specific Oracle APIs, understanding which data tiers apply, and identifying what already exists on our platform that can accelerate delivery.

Not every Oracle solution needs the same integration depth. We classify every application into one of three data tiers, which determines how data flows between ERPUX and your Oracle instance.

The tier choice drives architecture decisions: database schema, sync schedules, caching strategy, and how we handle Oracle downtime. We make this decision early because it shapes everything that follows.

The ERPUX platform has pre-built connectors for over 12 Oracle API families. When we start building your solution, the Oracle connection infrastructure is already in place:

This is the key advantage of building on ERPUX rather than starting from scratch with VBCS or APEX. We don't spend weeks writing Oracle API integration code. The platform already speaks Oracle natively.

We build a working proof-of-concept connected to your Oracle test environment. This isn't a mockup or a demo with fake data — it's your real Oracle data, your real security model, your real business units.

What the POC includes

• Core business logic — the main workflow or process the application solves
• Live Oracle data — connected to your test instance via certificate-based JWT
• Enterprise data grids — sort, filter, group, pivot, drill-down, export to Excel/CSV/PDF
• Oracle writeback where needed — creating transactions, updating records, submitting jobs
• Oracle security enforced — your roles and data access sets, not ours

Our tech stack

Every ERPUX application is built with:

The POC is built on a fixed-fee basis. If the POC validates successfully and you move to production, the POC fee is credited against your first year's subscription. Your investment is never lost.

Before going to production, we run the POC through validation with your team:

• Functional testing — does it solve the business problem as specified?
• Data validation — are the numbers correct against Oracle source data?
• Security testing — do roles and business unit restrictions work correctly?
• User acceptance — do the end users find it practical and usable?
• Performance — does it handle production-scale data volumes?

We iterate on feedback during this phase. The goal is a production-ready application that your team has signed off on before we go live.

Going live involves connecting to your production Oracle instance and embedding the application inside Oracle Fusion Cloud:

Once live, your users access the application from inside Oracle Fusion. They click a menu item or navigation link in Oracle, and the ERPUX application loads with their Oracle session already authenticated. No separate login, no context switching.

After go-live, the application enters its subscription phase. This is where the ERPUX model is fundamentally different from traditional custom development:

Every ERPUX application is priced by complexity tier. The deeper the Oracle integration and the more business logic involved, the higher the tier:

Pricing is per application, flat annual fee. No per-user charges, no transaction limits. Subscribe to 3 or more applications for bundle discounts.

Most clients start with one or two applications. Once the Oracle connection is established and the trust certificate is in place, adding new applications is significantly faster because the integration groundwork is done.

A typical expansion path looks like:

Each new application deploys independently but shares the same Oracle connection, security model, and user authentication. There's no re-integration work for each addition.

The Bottom Line

ERPUX isn't a tool you buy and figure out. It's a platform we use to build production-grade Oracle Fusion extensions — purpose-built for your specific needs, deployed on your instance, and fully managed as a subscription.

You describe the problem. We build the solution. You subscribe to it. We maintain it forever.

No OIC licenses. No VBCS developers. No quarterly update surprises. No infrastructure to manage.
