System Integration
Connect legacy and modern systems into a coherent, data-driven architecture — eliminating the operational friction that fragmented technology creates.
Most enterprises run on a patchwork of systems accumulated across years of acquisitions, department-level technology decisions, and successive generations of infrastructure. The cost of that fragmentation — in manual reconciliation, data inconsistency, process friction, and error — is often far greater than anyone realises until they measure it. Astrexa's integration practice resolves it systematically, rather than applying patches that create new problems.
01
Integration Architecture
We design integration architectures that fit your specific landscape and requirements. Event-driven architecture where throughput and decoupling matter. API-based integration where consistency and traceability are paramount. Batch processing where that is genuinely the appropriate pattern. We avoid imposing a preferred architectural style and avoid over-engineering solutions to problems that do not require it.
02
ERP & Core Systems Integration
We integrate ERP platforms — SAP, Oracle, Microsoft Dynamics — with adjacent systems including CRM, human capital management, supply chain, and financial consolidation tools. These integrations require deep domain knowledge of both the source and target systems, and careful attention to data mapping, transactional consistency, and error handling. Our practitioners have delivered them across industries and system generations.
03
Legacy Modernisation
We help organisations migrate away from ageing systems while maintaining uninterrupted business operations. Our approach applies strangler fig and anti-corruption layer patterns to incrementally replace legacy components, rather than high-risk big-bang replacements that require everything to be ready before anything goes live. Each increment delivers value and reduces risk.
04
Master Data Management
Fragmented systems produce fragmented data. We implement master data management programmes that establish a single, authoritative record for critical business entities — customers, products, suppliers, assets — and synchronise that record across all consuming systems. Clean master data is the foundation that makes every other integration project simpler.
05
API Management & Developer Experience
Where organisations are building integration capabilities for the long term, we implement API management platforms that provide security, versioning, rate limiting, and developer portals. Internal and external consumers should be able to integrate with confidence — with documented contracts, sandbox environments, and change notifications.
Our approach
How we deliver

Design
Architect the target integration model with agreed patterns, standards, and governance.
Integrate
Deliver integrations incrementally, validating each against agreed acceptance criteria.
Validate
End-to-end testing, performance validation, and handover documentation before go-live.
