Integration

Every system talking to every other, through interfaces you can see.

API design, event streaming and middleware that connect ERP, CRM, finance, HR and custom applications, with every message monitored.

Sound familiar

Where this usually starts.

Point-to-point connections accumulate until nobody can say what breaks when one system changes. We replace them with an integration layer designed on purpose: APIs with versioned contracts, events for things that happen, and middleware only where it earns its place. Every interface has an owner, a retry policy and an alert, so a failed message is visible within minutes rather than at month end.

Tick the ones that sound like your situation.

Scope

What is included.

  • Integration architecture

    A target design for how systems connect: APIs, events, batch and file transfer, each used where it fits.

  • API design and management

    REST and GraphQL APIs with versioned contracts, authentication, rate limits and a developer portal where one is needed.

  • Event streaming

    Kafka, cloud event buses and webhooks for things that happen, with ordering and replay designed in.

  • iPaaS and middleware

    MuleSoft, Boomi, Azure Integration Services, AWS integration services, n8n and Power Automate, configured and governed.

  • Monitoring and alerting

    End-to-end tracing of messages across systems, with dead letter handling and alerts that name the failed interface.

  • Interface catalog

    A living register of every integration, its owner, its contract and its dependencies.

Reference architecture

One layer between every system and everything that reads it.

This service builds the integration layer itself: the API gateway and event bus that sit between your CRM, HR and other systems of record and the portals that read from them, plus the monitoring and interface catalog that keep every connection owned once it is live.

What this service delivers here

  • CRM

    Customers, deals and the pipeline: where an order starts.

  • HR system

    People, roles, start and leave dates: the source of who gets access to what.

  • API gateway

    One front door for every API: authentication, rate limits and versions in one place.

  • Event bus

    A change is published once and consumed by every system that needs it, in order.

  • Customer portal

    Shows the state of an order without anyone polling the ERP.

  • Monitoring

    Every interface traced, with an owner and an alert when a delivery fails.

  • Interface catalog

    Every interface, its contract, its owner and what depends on it.

Walk through every flow in Integration

Before you start

Decisions to settle early.

  • Platform or plain code

    An iPaaS suits many standard connectors and a team that prefers configuration; hand-built services suit unusual logic and high volume. We recommend per interface, and most estates end up with both.

  • Events or requests

    Requests suit questions that need an answer now; events suit facts other systems should learn about. Choosing well decides how much breaks when one system is down.

  • Who owns each interface

    Ownership by the producing team, the consuming team or a central integration team each works, but mixing them silently does not. We agree the rule before building.

Approach

How the work runs.

  1. Map

    Every existing interface, including the undocumented ones

  2. Design

    Target integration architecture and contracts

  3. Build

    Integrations delivered in priority order behind tests

  4. Operate

    Monitoring, alerting and an owner per interface

Commercials

How it is bought.

  • A fixed-fee assessment

    We read your existing interfaces, schedules and failure logs, and map the estate as it really runs. You receive an interface inventory, the riskiest dependencies ranked, and a fixed price for the integration work that follows.

  • A fixed-price build

    The agreed interfaces are designed, built and tested in priority order, behind contracts in your repository. The price covers the gateway, event streams and monitoring named in the scope, with every assumption written into the proposal.

  • Running it afterwards

    Interfaces can be handed to your team with runbooks and alerting, or kept under our monthly operation, where we own failed deliveries, contract changes and the catalog against an agreed service level.

Start with the assessment.

Scope an assessment

Worked example

Order data keyed in three times.

Say a wholesale distributor takes orders in an e-commerce platform, re-keys them into its ERP and exports them nightly to a warehouse system. Errors surface when a customer calls about a missing delivery, and nobody can say which system holds the true order.

  1. Map

    We trace every movement of an order, including the nightly export a former employee scheduled and the spreadsheet finance uses to reconcile it.

  2. Contract

    An order event is defined once, with an owner and a version, and each system publishes or consumes it instead of copying fields by hand.

  3. Build

    Integrations are built behind tests in priority order, starting with the path from storefront to ERP, and run alongside the old process until the numbers agree.

  4. Watch

    Every message is traced end to end. A failed order lands in a dead letter queue and alerts the owner of that interface, not the whole team.

At the end, an order is entered once, the catalog shows which systems touch it, and a failure reaches the person who can fix it before the customer notices.

An illustration

An illustration, not a client account.

Where it goes wrong

What we design out.

  • A layer nobody owns

    Integration platforms decay when no single person answers for an interface. Every connection we build has a named owner, an alert that reaches them and an entry in the catalog before it carries production traffic.

  • Contracts that drift

    When producers change payloads without telling consumers, failures surface weeks later. Versioned contracts and automated contract tests catch the change in the pipeline, before it is deployed.

  • Middleware for its own sake

    An iPaaS licence is not an architecture. We use middleware where it removes work, and plain APIs or events where it would only add a hop to debug.

Outcomes

What it changes.

  • Fewer manual handoffs

    Data entered once flows to where it is needed, so staff stop re-keying and reconciling.

  • Failures found in minutes

    Monitoring catches a failed message before it becomes a missing invoice or a lost order.

  • Upgrades without fear

    Versioned contracts let a system be replaced or upgraded without breaking the ones around it.

How you will know it is working

  • Failed messages are seen by the interface owner before anyone downstream notices.
  • A proposed change to one system can be checked against everything that depends on it.
  • Nobody re-keys data that already exists in another system.
  • New applications connect through the layer instead of adding another point-to-point link.

You keep

What you have at the end.

Handover pack

five items

  1. Interface catalog with owners and dependencies Every integration listed with its owner, contract and the systems on either side, so a change can be assessed before it is made.
  2. Integration architecture and contract specifications The target design, and an OpenAPI or AsyncAPI contract for each interface, versioned alongside the code.
  3. Tested integrations in your repository Source, configuration and automated tests for every integration, in your version control rather than ours.
  4. Monitoring dashboards and alert routing Message flow, error rates and dead letter queues on dashboards, with alerts routed to the owner of each interface.
  5. Runbooks for every failure mode Step by step recovery for each way an interface can fail, from expired credentials to a replayed event.

The team

Who you work with.

  • Integration architect

    Designs the target layer, the contracts and the ownership model, and reviews every interface before it goes live.

  • Integration engineers

    Build, test and document the interfaces in your repository, and write the runbooks for each failure mode.

  • Operations engineer

    Sets up tracing, dead letter handling and alerting, and runs the interfaces if we operate them for you.

What we need from you

  • Access to the systems being connected, in a test environment where one exists.
  • A named owner on your side for each business process the interfaces serve.
  • Any existing interface documentation, however out of date.
  • Time from the people who reconcile data by hand today.

One owner for every connection between your systems.

Questions

Questions we get asked.

Should we buy an iPaaS or build middleware?

It depends on how many systems there are, how often they change and who will maintain the integrations. An iPaaS earns its licence when there are many connectors to manage and a team to govern them; a small set of high volume integrations is often cheaper and clearer as code. We compare both on your numbers before recommending either.

Can you integrate with a system that has no API?

Usually. Databases, file drops, message queues and, as a last resort, controlled screen automation can all be wrapped behind a proper interface, so the rest of the estate never deals with the legacy system directly.

How do you handle data that changes in two places?

By deciding which system owns each field and synchronizing in one direction wherever possible. Where two systems genuinely both write, conflict rules are written down and enforced in the integration, not left to whichever update arrives last.

How do you secure integrations?

Every connection authenticates with scoped credentials kept in a secrets manager, traffic is encrypted and access is reviewed. An integration account with administrator rights everywhere is one of the most common findings in the estates we inherit.

What is an interface catalog, and who keeps it current?

A register of every integration: what it connects, who owns it, which contract it follows and what depends on it. We build it during mapping and hand it over with the integrations. Keeping it current becomes part of your change process, so a new interface is not live until its entry exists.

How do you version an API without breaking the systems that use it?

Contracts change additively wherever possible: new fields are optional and old ones keep working. When a breaking change is unavoidable, the new version runs alongside the old one, consumers are told when the old one retires, and usage is monitored so nothing is switched off while it is still being called.

What happens to a message when the receiving system is down?

It waits rather than disappearing. Retries follow a backoff policy, and a message that still cannot be delivered moves to a dead letter queue with the reason recorded. The owner is alerted, and the message can be replayed once the receiving system is back.

Can you work alongside our own integration team?

Yes. Many engagements are a mix: your team owns some interfaces and we build or rescue others. We use your repositories, review process and tooling where they exist, and the catalog and runbooks are written so either team can operate any interface.
