Low-code finance apps built on Mendix — closing the ERP gaps that automation alone couldn't.
How CODE81 delivered Mendix-based finance applications integrated with Oracle EBS — productionising the workflows the existing ERP couldn't handle, and the headless payment orchestration application that unified supplier payments across systems.
Low-code platform delivering finance apps at the pace operations required
Payment orchestration app architected as a headless service
Independent scaling and easier ongoing maintenance
01 / THE CHALLENGE
Workflows the ERP couldn't handle — without rebuilding the ERP.
Gaps in an Oracle EBS implementation required automation of finance services and a unified approach to orchestrate supplier payments — but rebuilding the ERP wasn't on the table.
The fastest path to closing ERP gaps isn't a new ERP. It's purpose-built apps sitting alongside the existing system, integrated through clean APIs, owned by the business teams that use them. The client needed finance apps that could be delivered fast, maintained easily, and scaled independently of the underlying ERP — without losing the integration with Oracle EBS as the system of record.
02 / OUR ROLE
What CODE81 delivered.
Three streams of application development — combining low-code finance app delivery, headless payment orchestration, and the microservice architecture that lets each piece evolve on its own timeline.
- Built finance services applications on Mendix — productionising critical workflows around the existing Oracle EBS as the system of record.
- Developed a headless payment orchestration application resolving gaps across multiple payment systems — exposing payment orchestration as a service consumable by other apps.
- Designed the application portfolio on microservice architecture, ensuring each app could scale and be maintained independently of the others.
03 / IMPACT
Three outcomes specific to the application portfolio.
Outcomes reported by the client across the application delivery workstream.
/ OUTCOME 01
Automated Finance Apps Live
Finance services apps live in production, automating workflows that previously required manual processing around ERP gaps.
/ OUTCOME 02
Unified Payment Orchestration
A headless payment orchestration app unifying supplier payments across multiple systems and gateways — payment as a service, callable from any frontend.
/ OUTCOME 03
Independent Scalability & Maintenance
Microservice architecture enabling each finance app to scale and be maintained independently — no big-bang releases, no shared blast radius.
04 / TECHNOLOGY
Built on Mendix, integrated with Oracle EBS, architected as microservices.
Low-code application delivery combined with disciplined microservice architecture — fast to build, easy to integrate, and structured for long-term maintainability.
