Data, API & Systems Integration
Connect the systems your organisation depends on.
For established UK SMEs, repeated data entry and disconnected reports cost time and money. Through the Business Improvement Partnership we connect CRM, finance and operational systems, then improve the workflows around them. Reserved monthly capacity keeps the work moving, with priorities agreed around the business impact.

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.
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 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 bespoke software development 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.
- 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.
Documented interfaces and reusable connections make it easier to add platforms as the business grows, with new work prioritised through your monthly roadmap.
Technical considerations
Engineered for the failures that will happen.
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, the operational view shows what failed, where, and how to recover it. The partnership’s support times describe acknowledgement during its published working hours; resolution work uses the monthly allowance.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
Your agreement defines integration-code ownership and handover. We document credential access, vendor account responsibilities, architecture and operational runbooks so your team understands how to operate and support the integrations.
How we deliver
From disconnected systems to one dependable flow.
Discover
Which systems hold which records, what each API genuinely exposes, and why the connection matters commercially.
Define
The flows, the source of truth for every field and the conflict rules set down in writing.
Design
Contracts, mappings, retries and failure paths worked out before a single record moves.
Engineer
Each flow built and reviewed connection by connection, with a senior engineer answerable for every contract.
Validate
Exercised against vendor sandboxes, replayed messages and deliberately broken endpoints.
Launch
Cut over with dashboards, alerts and a rollback path live before the first production record flows.
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.
See selected workStandards 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 and volumes grow. The Business Improvement Partnership brings maintenance and further integration improvements into your monthly priorities. We agree the work, its dependencies and how much capacity it needs.
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. We deliver this work through the Business Improvement Partnership, with 4, 8 or 16 days of monthly capacity shared across software, AI and consulting. Discovery and integration work use that allowance. Together we prioritise dependable improvements around the time, cost and errors they can remove. Published pricing makes the monthly commitment clear; third-party software, cloud and API costs are agreed separately.
