System Integration

System Integration Company That Makes Disconnected Systems Talk — Securely, in Real Time.

Your CRM, EHR, billing, and custom tools live in silos. We design and build the integration layer that connects them into one ecosystem — real-time data sync, automated workflows, and a single source of truth. In healthcare: standards-based interoperability (FHIR, HL7, GP Connect) built to pass audit.

Sound Familiar?

You need to integrate 12 systems — and none of them talk to each other.

Your CRM, ERP, billing, logistics, and customer portal live in separate silos. Staff manually re-key data between them, costing hours daily and introducing errors that cascade across operations.

Your clinical systems can't exchange data with the NHS estate.

You need FHIR UK Core, GP Connect, the NHS App, e-Referral Service (eRS), or SNOMED CT — but your platform was built before interoperability was a requirement, and your team has never implemented these standards.

Your integrations are brittle and break every time a vendor updates an API.

Point-to-point connections held together with custom scripts fail silently. Nobody knows a sync broke until the data is already wrong, and there’s no monitoring, no retry logic, and no audit trail.

A legacy system holds your business hostage.

The platform that runs operations was built on deprecated technology by a team that no longer exists. You can’t replace it overnight — but you need modern systems to read from and write to it without a big-bang rewrite.

A procurement or audit requires interoperability evidence you can't yet produce.

A tender, a partner, or a regulator wants proof your platform exchanges data to standard — and u0022we can build thatu0022 isn’t the same as u0022here’s how we’ve done it.u0022

Integration Is Where Projects Quietly Fail

The hardest part of most software projects isn’t the feature — it’s making it work with everything that already exists. Brittle integrations are the silent cause of failed go-lives, audit findings, and u0022the data doesn’t matchu0022 escalations. We treat the integration layer as a system in its own right: monitored, versioned, retried, and auditable.

System Integration Services

API Integration u0026 Development

Connect your business systems through one gateway.

We design and build the APIs and middleware that connect your business systems — REST, GraphQL, gRPC, webhooks, and event streams. Real-time bidirectional sync, data transformation and validation, and a unified gateway so every system reads from one source of truth.

  • Unified API gateway connecting all business systems
  • Real-time, bidirectional data synchronization
  • Custom middleware handling transformation, validation, and error recovery
  • Webhook and event-driven architecture (Kafka, RabbitMQ)

Healthcare Interoperability

For clinical platforms exchanging data across the health estate.

We implement standards-based interoperability and integrate with national infrastructure — designed to survive clinical-safety and information-governance review.

  • FHIR (incl. UK Core) and HL7 v2/v3 message exchange
  • NHS integrations: GP Connect, NHS App, e-Referral Service (eRS), PDS
  • Terminology and coding: SNOMED CT, dm+d, ICD-10
  • EHR/EMR integration and clinical data exchange with full audit trail

Enterprise Application Integration (EAI)

Stitch together CRM, ERP, finance, HR, and operational tools.

We replace manual data entry and spreadsheet bridges with automated workflow orchestration across platforms.

  • CRM/ERP integration (Salesforce, Dynamics, and custom systems)
  • Identity and access integration (OAuth 2.0, SAML, SSO, SCIM)
  • Workflow orchestration and process automation across systems
  • Reporting and analytics consolidation from multiple sources

Legacy Modernization u0026 Data Migration

For companies trapped by outdated systems.

We wrap legacy platforms in a modern API layer, migrate data with integrity validation, and transition incrementally — no downtime, no big-bang risk.

  • Modern API layer wrapping legacy systems during transition
  • Zero-downtime, incremental migration strategies
  • Legacy database migration with data-integrity validation
  • Parallel-run operation until the new path is fully validated

How We Build Integrations

1

Integration Assessment (Free, 30 min)

We map your current systems, data flows, and the standards or APIs in scope, then tell you where the real complexity (and risk) is.

2

Discovery u0026 Integration Design (Weeks 1–3)

We document every data flow, define API contracts and the canonical data model, choose the integration pattern (point-to-point, hub, event-driven), and design for monitoring and error recovery from the start.

3

Build u0026 Validate (Sprints)

We build in 2-week sprints with each integration deployed to a staging environment, validated against real payloads, and load-tested. For healthcare, conformance is tested against the relevant standard.

4

Monitor, Document u0026 Hand Over

Production monitoring, alerting, retry logic, and audit trails — plus architecture documentation and a data-flow map your team and auditors can rely on.
