Service · Legacy Modernisation

The system everyone's
afraid to touch

Staged modernisation of the platform your business depends on — while the business keeps running.

The problem, in your words

There's a system at the heart of your business that's been there for a decade. The person who built it left. It's slow, it breaks in ways nobody understands, it can't do what the business now needs — but it works, mostly, and every quote you've had for replacing it sounded like open-heart surgery priced by the hour.

What we actually build

Assess before we prescribe

A Discovery Sprint on a legacy system produces a plain-English map of what you have, what's at risk, and a staged plan — because "rewrite everything" is almost always the wrong answer.

Strangler-pattern migration

We move functionality out of the old system piece by piece, so the business never stops and there's no big-bang cutover to fail.

Replatform to the cloud

Ageing servers to AWS, usually cutting hosting and maintenance costs in the process.

Rescue and stabilise

Sometimes the right first move is simply making the current system safe — backups, monitoring, documentation — and buying you time to decide calmly.

What an engagement looks like

Discovery Sprint (£2,400, two weeks) → staged plan with a fixed quote per stage → migration in sprints, old system running until each piece is proven. Typical programmes: 2–6 months, spend spread across them.

What it costs

Stabilisation work from £3,800; staged modernisation programmes typically £18,000–£70,000 across several months. Full detail on the Rates page.

Why us for this

This is the founder's signature work. At Blink Payment he directed the migration of a live, PCI DSS-regulated card payment platform from a monolith to AWS serverless — infrastructure costs down 34%, uptime held at 99.99%, millions of requests a month, no pause in the business. Your stock-control system will honestly be a relief after that.
