Systems Integration

Connect the systems your organisation depends on.

Every re-keyed record, missed webhook and out-of-sync report is a tax on the whole business. Veda Software provides systems integration and API development that make CRM, finance, operational and third-party platforms behave as one — engineered for the failures that will happen, not just the happy path.

Your first conversation is with a senior engineer, not a salesperson.

Sound familiar?

Disconnected systems tax every team, every day.

  • The same order, customer or invoice is typed into two or three systems by hand — every single day.
  • Sales, finance and operations each run their own numbers, and the numbers disagree.
  • Month-end means exporting spreadsheets from one system to reconcile against another.
  • An integration built years ago fails silently — you find out from a customer, not an alert.
  • A supplier or platform offers a perfectly good API, but nobody has engineered a proper connection to it.
  • You want to give customers a portal or a mobile app, but the data it needs lives in four places.

What it is

Four disciplines that make separate systems behave as one.

Systems integration is the engineering of dependable connections: moving the right data, at the right moment, between systems that were never designed to talk to each other — and proving it keeps working after everyone has stopped watching. It is unglamorous work with a clear commercial purpose, and it is done properly or it is a liability.

  • API development

    APIs designed and built over your existing systems — documented, versioned and secured — so your data can be reached deliberately by the applications and partners that need it, rather than extracted by workaround.

  • Platform-to-platform integration

    CRM, finance, payments, e-commerce and third-party platforms connected through their APIs, with the field mapping, rate limits and edge cases handled explicitly instead of discovered in production.

  • Data synchronisation

    Records kept consistent across systems — event-driven or scheduled — with an agreed source of truth for every field and written rules for what happens when two systems disagree.

  • Workflow integration

    An event in one system triggering the right action in another, and the whole flow surfaced in the portals, dashboards and mobile apps where people actually work.

Honest fit

When integration is the answer — and when it is not.

Integration is only worth building when the systems being connected are worth keeping and the process between them is real. Part of our job is telling you which side of that line your situation sits on.

Integration is right when

  • Your systems are individually sound but operationally disconnected.
  • Off-the-shelf connectors have hit their ceiling — volume, complexity or logic they cannot express.
  • A vendor, customer or partner exposes an API, and the connection deserves proper engineering.
  • Customers, suppliers or field teams need to see data that currently lives across several systems.
  • Manual re-keying and reconciliation are consuming real hours every week.

It is not right when

  • The core system itself is failing. That calls for rescue and modernisation, not another connection to it.
  • A native, supported connector already does the job well. Use it — we will tell you when that is the answer.
  • The process being connected is not defined yet. Integration automates a process; it cannot invent one.
  • Volumes are so low that a documented manual step is genuinely cheaper to operate. We will say so.

What we deliver

Deliverables that survive contact with production.

Where the integrated data needs a front door — a portal, a dashboard, a mobile app — we build that too, as part of our web application development work.
  • Integration architecture: systems, data flows, ownership and sequencing mapped before any code is written
  • Custom API development — documented, versioned and secured for internal teams and external partners
  • CRM, finance and payment-platform integrations, engineered against vendor sandboxes before touching production
  • Customer and supplier portals, dashboards and mobile apps built over the integrated data
  • Data synchronisation built idempotent and replayable, with conflict rules agreed in writing
  • Workflow automation across systems — including AI-assisted steps only where they earn their place
  • Monitoring, alerting and failure dashboards in place from the first release, not bolted on later
  • Documentation, runbooks and handover your own team can operate without depending on us

Business outcomes

One version of the truth, everywhere it matters.

  • One version of the truth.

    Sales, finance and operations stop debating whose numbers are right and start acting on the same record.

  • Recovered hours, every week.

    Re-keying and month-end reconciliation come off desks permanently — not just until the workaround breaks again.

  • Failures you hear about first.

    Problems surface as alerts with a recovery path, not as customer complaints several days after the data went wrong.

  • Room to grow.

    New platforms, partners and products connect in weeks rather than quarters, because the architecture assumed there would be more connections.

Technical considerations

Engineered for the failures that will happen.

Integrations fail at 2am, on bank holidays, and the day a vendor ships an unannounced API change. The engineering below is how a connected estate stays trustworthy anyway.

  • Idempotency and retries

    Every write path is designed to be retried safely. Idempotency keys guarantee that a replayed job or a duplicate webhook can never create a second payment or a duplicate record. Failed messages land in dead-letter queues for inspection and controlled replay, with exponential backoff rather than hammering a struggling endpoint.

  • Observability

    Structured logs with correlation IDs that follow a record across every system it touches, plus dashboards and alerting on sync lag, error rates and queue depth. When something fails out of hours, the on-call view says what failed, where, and how to recover it.

  • Contracts and versioning

    Schema validation at every boundary, versioned APIs and explicit compatibility rules — so a vendor’s “minor” API change breaks loudly in staging instead of silently corrupting data in production.

  • Security

    Least-privilege credentials scoped per system, secrets held in managed vaults rather than configuration files, encrypted transport throughout, and audit trails recording what data moved where, when, and on whose authority.

  • Environments and testing

    Development, staging and production environments wired to vendor sandboxes where they exist. Contract tests and integration tests run in CI, so regressions in a data flow are caught before deployment rather than reported by users.

  • Ownership and documentation

    The integration code, the credentials and the vendor accounts are yours. Architecture documentation and operational runbooks are part of the deliverable — control of the codebase stays with you.

How we deliver

From disconnected systems to one dependable flow.

  1. Discover

    Which systems hold which records, what each API genuinely exposes, and why the connection matters commercially.

  2. Define

    The flows, the source of truth for every field and the conflict rules set down in writing.

  3. Design

    Contracts, mappings, retries and failure paths worked out before a single record moves.

  4. Engineer

    Each flow built and reviewed connection by connection, with a senior engineer answerable for every contract.

  5. Validate

    Exercised against vendor sandboxes, replayed messages and deliberately broken endpoints.

  6. Launch

    Cut over with dashboards, alerts and a rollback path live before the first production record flows.

  7. Evolve

    Connections monitored and extended as vendors deprecate, volumes grow and new platforms arrive.

Relevant work

Integration proof, in production.

The clearest evidence for integration work is systems that have been exchanging data reliably in production for a long time. Our selected work shows the platforms we have connected and what that removed from people’s weeks.

Standards and stewardship

Safe at every boundary, watched long after launch.

Integrations carry your most sensitive data across system boundaries, so they are built to our security and quality standards: least-privilege access, encrypted transport, tested releases, code review and documented environments.

APIs change, vendors deprecate, volumes grow. Our ongoing software development keeps connections monitored, patched and evolving — instead of quietly rotting until the day they matter most.

Common questions

Systems integration, answered honestly.

The questions buyers actually ask before commissioning integration work — including the ones about money, failure and ownership.

It depends on how many systems are involved, the quality of their APIs, the data volumes and how much failure handling the flows justify. A two-system synchronisation is a very different engagement from a multi-platform programme with portals on top. Every project starts with a paid discovery phase that produces a fixed, evidenced proposal — so you commit to a known scope, not an open-ended estimate.
