Two hundred integrations, and counting.

Nearly twenty years of making systems that were never meant to talk to each other talk to each other. If it has an API we have probably already written against it - and when it has not, we have built the connector anyway.

WHAT WE HAVE CONNECTED

A representative list.

Not exhaustive - most of the two hundred were written for one client and one system, and never got a logo.

WHEN THERE IS NO API

There is always a way in.

Half the systems a business depends on were written before anybody thought about integration. That has never been a reason to say no.

SFTP and file drops

A watched folder, a fixed layout and a parser that does not fall over when the supplier changes a column.

Straight at the database

Read-only views, change tracking or a staging table, where the vendor will allow it and the licence permits.

Custom middleware

A small service that sits between two systems that will never speak the same language, and translates.

Queues and webhooks

So a slow third party cannot take your own system down with it when it has a bad afternoon.

HOW WE BUILD THEM

The bits that stop it breaking at 3am.

  • Every call is idempotent - retrying it does not double an order or an invoice.
  • Failures queue and retry with backoff instead of vanishing into a log nobody reads.
  • Every request and response is logged, so a dispute can be settled with evidence.
  • Credentials live in a vault, not in a config file in source control.
  • We build against the sandbox first, then switch endpoints - never test in your live ledger.
  • Alerting when a feed goes quiet, because the dangerous failure is the silent one.
One thing worth saying plainlyAn integration is not finished when it works once. It is finished when it survives the other side changing something without telling you. That is what most of the 200 we made do.

Tell us what's broken.

Send us the spreadsheet, the carbon-copy book or the system nobody can maintain any more. We'll tell you what we'd do about it - and whether it's worth doing.
