APIs & Integrations
We engineer secure, reliable connections between your core systems, eliminating manual data movement and reducing operational failure points.
Operational data often sits across disconnected systems: ERPs, CRMs, billing platforms, spreadsheets, legacy mainframes, and modern SaaS tools. This creates manual re-keying errors, inconsistent reporting, operational bottlenecks, and expensive third-party middleware dependencies. We build the integration layer that connects everything properly.
What This Service Is
What problem does this solve?
Operational data often sits across disconnected systems: ERPs, CRMs, billing platforms, spreadsheets, legacy mainframes, and modern SaaS tools. This creates manual re-keying and transcription errors, inconsistent reporting with no single source of truth, bottlenecks in sales, finance, and operations, and high dependency on expensive third-party middleware.
Typical Deliverables
- Secure API layers between core systems
- Middleware and microservices orchestration
- Legacy system wrappers (without rip-and-replace)
- Data synchronisation and transformation pipelines
- Automated partner and product feeds
When You Typically Need This
Data Silos Are Blocking Visibility
Operational data is scattered across systems, preventing accurate reporting or automation.
Manual Re-Keying Is Creating Risk
Staff must enter the same information multiple times across systems, increasing errors and slowing workflows.
Legacy Systems Can't Be Switched Off
Mission-critical systems are 10–20 years old but still essential; yet they don't integrate with modern platforms.
Middleware Is Becoming Expensive
Licensing models based on API calls are driving seven-figure annual costs.
Growth Through Acquisition
Mergers have created a fragmented infrastructure of systems that don't communicate.

How We Deliver It
Architecture-First Approach
We analyse the full system estate before building anything, ensuring integrations slot into long-term strategy rather than creating new silos.
Incremental Modernisation
We modernise "in flight" by wrapping or replacing components gradually, avoiding disruption to live operations.
Risk Management
We prioritise transaction safety, data integrity, and production stability, particularly in high-volume environments.
Client Ownership
You retain ownership of your APIs, microservices, and infrastructure. We design to reduce vendor lock-in.
Outcomes & Business Impact
The outcomes and benefits vary significantly from business to business. The examples below are typical, but your specific results will depend on your context, current state, and business objectives. We review these individually during discovery.
Technology & Architecture
Backend & APIs
Custom RESTful APIs, microservices architectures, and event-driven orchestration platforms.
Data & Integration
Structured transformation pipelines, legacy system wrappers, and secure data synchronisation patterns.
Cloud & Infrastructure
Containerised deployments (e.g. Kubernetes), cloud-agnostic infrastructure principles, and scalable transaction processing.
Security & Compliance
Audit-ready transaction logging, secure API authentication and access control, alignment with PCI DSS, SOC 2, ISO 27001.
Where This Service Is Used
Integration-led transformations have included: wholesale invoice verification and transaction processing at telecom scale, automated KYC and credit checks embedded into Salesforce workflows, MuleSoft exit strategy supported by proprietary complexity analysis, multi-tenant ordering platforms unifying franchise networks, and ERP and accounting system integration for pricing and quoting automation.
Atlantix Education — Automating Recruitment Intake
Implemented an automated recruitment intake pipeline that processes candidate applications, extracts CV data, and synchronises directly into Bullhorn CRM, reducing manual admin and enabling immediate candidate acknowledgement.
Centralised Pricing and Product Management Platform
Designed and built a centralised pricing and product management platform to replace fragmented spreadsheets, enabling tiered customer pricing, automated quote generation, Xero integration, and API-driven price distribution.
Ecotalk — Automating Telecom Billing and Account Management
Modernised Ecotalk's billing and account management infrastructure with automated usage-based billing, secure integrations, and self-service portals, eliminating manual triggers and improving revenue predictability.
Vodafone Germany — Modernising Wholesale Invoice Verification 2
Modernised Vodafone Germany's wholesale invoice verification platform with a cloud-native, distributed architecture, eliminating vendor dependency and increasing throughput.
Frequently Asked Questions
Can you integrate with legacy systems that have no modern APIs?
Yes. We build wrappers, middleware layers, or custom connectors to extend functional life without replacing core systems.
Do we have to replace our existing middleware?
Not necessarily. We assess cost, risk, and flexibility before recommending replacement.
Will this disrupt live operations?
Our approach prioritises incremental rollout alongside existing systems to minimise production risk.
How long does an integration project take?
Timelines depend on system complexity, number of integrations, and data volume. We define scope during discovery.
