API Integration Company, UK
We make your business systems talk to each other — reliably, securely, and without you having to babysit a spreadsheet. Accounting, CRM, e-commerce, bespoke tools: if it has an API (or even if it doesn't), we can connect it.
Most UK businesses run on a patchwork of great tools that don't share data. The result is manual re-keying, mismatched records, and reports that are out of date the moment you run them. A good integration removes that work entirely.
Outcomes
- Hours of manual data entry removed every week
- One source of truth across your systems
- Fewer errors from copy-paste and re-keying
- Up-to-date reporting without the manual export
System & data-flow mapping
We start by mapping exactly how your data moves today — and where it breaks — in a fixed-price Integration Health Check.
Reliable, monitored integrations
Built to handle API rate limits, retries and edge cases, with monitoring so you know it's working — not a brittle script that fails silently.
Custom or off-the-shelf — on the merits
We're vendor-neutral. If Zapier, Make or a native connector is the right answer, we'll tell you. If you need custom, we build it.
Clear handover
Documentation and monitoring so the integration is never a black box you depend on us to understand.
Which systems can you integrate?
Common UK stacks — Xero, QuickBooks, Sage, Shopify, WooCommerce, HubSpot, Salesforce, Stripe, Microsoft 365 — plus bespoke and legacy systems via their APIs, files or databases.
What if our tool doesn't have an API?
We can often still integrate via scheduled file exports, databases, or robotic approaches. The Health Check tells us what's realistic before you commit.

Why Integrations Fail (and How to Build Ones That Last)
Why business integrations break or quietly stop working — the real failure modes (API changes, token expiry, rate limits, data drift, no monitoring) and how to keep them alive.
