Trusted By Growing Businesses & Enterprise Teams

Integration work succeeds when delivery is calm, secure, and documented. We help teams connect systems with a clear plan, clean implementation, and a handover that is easy to run.

Build a single, reliable flow between the tools you run

When your platform spans multiple products and vendors, the fastest wins often come from getting data moving cleanly between them. We approach systems integration as a product capability: defined events, clear ownership, and a runbook your team can operate.

If you need one source of truth across customer, orders, finance, and operations, a well-scoped systems integration programme keeps delivery predictable while improving decision confidence.

Common Integration Outcomes

  • Keep customer and account data consistent across systems
  • Sync orders, invoices, and refunds with clear state changes
  • Automate onboarding steps across product, support, and ops
  • Standardise identifiers so reporting stays trustworthy
  • Introduce an event model that supports future change
  • Add monitoring so issues are visible and owned

Ideal for multi-tool stacks

What we deliver for integration-heavy platforms

We design integration layers that are easy to change, easy to test, and easy to run. That includes mapping data contracts, choosing the right sync patterns, and shipping connectors with monitoring and documentation from day one.

Integration Planning & Architecture

System map, data ownership, event model, and a delivery plan that sequences work by value and dependency, not guesswork.

API & Connector Build

Secure endpoints, webhooks, and custom api integration where off-the-shelf connectors do not match your rules or workflows.

Data Sync, Reliability & Observability

Idempotency, retries, queues where needed, plus logs, alerting, and dashboards so integration operations are visible and owned.

Testing, Documentation & Handover

Contract tests, integration test packs, runbooks, and a handover session so your team can operate changes with confidence.

Our Process

A clear delivery model for integration work

Discovery, Scoping & Mapping

Align outcomes, data ownership, and the simplest path to a stable first release.

We capture the systems involved, key workflows, data entities, and success criteria, then produce a scope direction note and timeline options.

  • System and workflow map
  • Data ownership and contract outline
  • Auth and security approach
  • Phased plan with review gates
Sense-check scope

30-minute call, next steps and action plan

Architecture, Patterns & Contracts

Choose the right sync pattern so performance, reliability, and ownership stay clear.

We define events, payloads, idempotency rules, and error handling, then confirm the build backlog and release shape.

  • Data contracts and versioning approach
  • Sync pattern selection (events, jobs, queues)
  • Rate limits, retries, and fallbacks
  • Test strategy for connectors
Review the design

30-minute call, next steps and action plan

Build, Testing & Monitoring

Ship connectors with visibility so operations stay calm after go-live.

We implement endpoints and connectors, add logging and alerts, and run contract tests and integration test packs before release.

  • Connector implementation with retries
  • Contract tests and integration tests
  • Logs, dashboards, and alert rules
  • Runbook draft for operators

Launch, Handover & Support

Move to a stable operating rhythm so future changes are easier, not harder.

We release with a checklist, finalise runbooks and ownership, and set an operating cadence to interconnect web systems safely as your stack evolves.

  • Release checklist and rollback plan
  • Runbooks and ownership clarity
  • Monitoring and incident pathways
  • Support and iteration options

Frequently Asked Questions

How do you estimate cost for a complex integration across multiple systems?

We estimate cost by scoping the workflows, data entities, sync frequency, and operating requirements, then mapping phased delivery options. This matters because integration effort is driven by edge cases, ownership, and reliability expectations. You will get a scope direction note, a phased plan outline, and the key decisions that change effort so your internal stakeholders can align early.
We need your system list, key workflows, priority outcomes, and access to API docs or sandbox environments to scope accurately. This matters because missing inputs create uncertainty in contracts, auth, and testing. You will get an integration questionnaire, a system map draft, and a clear list of access items so discovery can move fast.
We choose events or schedules based on business urgency, data volume, downstream dependencies, and how you want to observe and recover from errors. This matters because the wrong pattern can create noisy failures or stale reporting. You will get a pattern recommendation with trade-offs, and an error-handling approach aligned to your operating model.
We implement the right auth method (OAuth2, tokens, keys) with secure storage, least-privilege access, and audit-friendly handling. This matters because integration credentials become a shared risk across systems. You will get an auth approach note, environment separation guidance, and a checklist for secure token management and rotation.
Yes, we can bridge legacy systems using adapters, scheduled extracts, controlled file interfaces, or middleware where appropriate. This matters because the goal is stable data movement, not forcing a platform change. You will get a feasibility outline, a connector strategy, and a phased path that reduces disruption while improving reliability.
We prevent mismatches by defining ownership, identifiers, contracts, validation rules, and idempotent processing with clear recovery steps. This matters because mismatched data undermines reporting and customer operations quickly. You will get a data ownership map, a contract outline, and a test pack plan that covers edge cases and retries.
We include contract tests, integration tests, and release readiness checks aligned to the workflows that matter most to your operations. This matters because integrations can appear fine until a downstream edge case hits production. You will get a testing approach, sample contracts, and a release checklist to reduce regressions when APIs change.
We add logs, alerts, dashboards, and runbooks so integration operations are visible and owned by the right team from day one. This matters because fast detection and clear ownership reduce disruption when failures happen. You will get an observability plan, alert thresholds, and an operator runbook that supports predictable support.
We design for rate limits using batching, backoff, queues where needed, and versioning so vendor changes can be managed safely. This matters because external platforms change timelines you do not control. You will get a resilience checklist, a versioning plan, and a change-handling workflow you can use repeatedly.
Ownership can sit with your team, our team, or shared, as long as runbooks, access, and change governance are defined clearly. This matters because unclear ownership causes slow fixes and risky changes. You will get a handover pack, documentation standards, and a simple operating cadence that fits your team setup.
Yes, we document data contracts, endpoints, flows, error handling, and recovery steps in a handover-ready format your team can run. This matters because integrations outlive projects and need safe iteration. You will get runbooks, diagrams, and a walkthrough session so maintenance is practical, not theoretical.
First release speed depends on access readiness, scope clarity, and the simplest workflow you want to automate as the starting point. This matters because the fastest path is usually a narrow, high-value flow with clean contracts. You will get a phased plan with a first-release recommendation and the dependencies to unblock early.
