A national healthcare provider had a legacy 2019 system that could not talk to the rest of their stack. Client data lived in their CRM. Invoicing happened in their finance app. Clinical measurements sat in 33 standalone databases, one per clinician. Claims went through a closed government portal with no API. Every handoff between systems was manual, every reconciliation a workaround.
Extranet Systems delivered a unified platform with deep, purpose-built integrations across the provider’s entire operational stack. Bi-directional CRM sync kept client records and call outcomes consistent across sales and clinical teams. The finance app handled invoice generation and payment workflows seamlessly. All 33 standalone clinical databases were consolidated into one cloud-hosted, region-segregated source of truth. Address validation, document storage, and AI services were integrated through a modular architecture designed to add new connectors without rebuilding the core.
The provider eliminated reliance on its 2019 legacy system, consolidated 33 standalone databases into a single source of truth, and removed the manual handoffs that previously bridged disconnected systems. They were replaced with real-time, audited, bi-directional data flow.
"We went from three disconnected tools to one unified system in 12 weeks. The team hasn't looked back, and neither have we."

Every system in your organisation holds valuable data. Enterprise application integration breaks down the silos between them, creating a unified technology ecosystem.
Enterprise systems that operate in isolation create duplicated data, manual handoffs, and fragmented visibility. Integration stops this.
Whether it is your ERP, CRM, databases, cloud platforms, or legacy infrastructure, we connect every layer of your technology stack.
Everything you need to know about building custom software with us
Enterprise application integration (EAI) is the process of connecting the multiple software systems across your organisation so they share data and communicate automatically. Without integration, each system operates as a silo, requiring manual data entry between platforms, creating duplicated records, and leaving teams working from incomplete or inconsistent information. Integration eliminates these problems by creating a unified technology ecosystem where data flows reliably across every application.
We integrate a broad range of enterprise systems including ERP platforms, CRM systems, databases, cloud services, ecommerce platforms, accounting tools, HR systems, custom-built applications, and legacy infrastructure. We design the integration architecture around the specific systems in your technology stack.
Point-to-point integration connects individual systems directly to each other, which works for a small number of systems but becomes complex and difficult to maintain as your technology stack grows. An integration platform or middleware approach creates a central layer through which all systems communicate, making the architecture more scalable, easier to manage, and more resilient as your business evolves.
We have experience integrating legacy systems that lack modern API capabilities, using a range of techniques including database-level integration, file-based data exchange, middleware adapters, and custom connectors to bridge the gap between older infrastructure and modern platforms without requiring costly system replacement.
Timelines depend on the number of systems involved, the complexity of your data flows, and the state of your existing infrastructure. We develop a clear integration roadmap and phased delivery plan at the outset so you have visibility over every stage and can start realising value from early integrations before the full project is complete.
Yes. We provide continuous monitoring, issue resolution, and support across your entire integration environment, ensuring data keeps flowing reliably as your systems, business processes, and technology stack evolve over time.
Less duplication. Faster workflows. One version of the truth.
We don't disappear after kickoff and resurface six months later with a finished product. Every stage is collaborative, transparent, and designed to keep you in control.
Core business systems connected for seamless data flow across finance, operations, and customer management.
Older infrastructure connected to modern platforms without costly replacement or operational disruption.
Hybrid integration architectures that bridge your on-premises systems with cloud platforms and services.
Custom APIs and middleware layers that enable reliable, scalable communication between enterprise systems.
Live data flowing between systems automatically so every team always works from current, accurate information.
Automated cross-system workflows that eliminate manual handoffs and keep business processes moving efficiently.
We bring deep enterprise integration expertise across a broad range of platforms and technologies, delivering connected, resilient business environments with ongoing support built into every engagement.
Your web application should work the way you do, not the other way around. Let's build something that actually fits.
