/ What we build

The old system still runs the business. That is exactly why nobody touches it.

01

Old desktop software to the web

Software that only works on office computers, moved to the browser and usable from anywhere.

02

Old websites and portals

Sites built on outdated technology, rebuilt so they are faster, safer and easier to change.

03

Moving your data safely

Every record moved, checked and matched against the old system before anyone relies on it.

04

Old and new side by side

Both systems run together until the new one is proven. Your team switches over when it is ready.

05

A way back at every stage

Each step has a rollback plan. If something goes wrong, you are back on the old system the same day.

06

A system more than one person understands

Full documentation and handover, so the knowledge no longer sits in one person's head.

/ Proof

/ How it works

One part at a time. The business keeps running throughout.

No big-bang switch. We move one part, prove it works, then move the next.

  2. 2

    One part at a time

    Moved, checked and proven.

    Each part runs alongside the old system until the results match. Then your team switches over.

    At every stage

    A way back.

    Every step has a rollback plan, agreed with you before we start it.

  4. 4

    From first call to final switch-off

    A director owns your project.

    One person responsible from start to finish. No handover to a sales team.

/ Ways to start

Two ways to start. Pick the one that fits you.

01

Fixed-price modernization

Agreed scope and a fixed price, within 3 business days of discovery. Delivered one part at a time.

Best if: you know which system needs replacing and want the cost locked.

  • Agreed scope and payment schedule
  • No surprise bills. Changes only with your written approval
  • You get the new system, the code, and support or a full handover

02

Managed team

Named engineers modernizing your systems over time, at a monthly rate. Three-month minimum.

Best if: you have several old systems to move, one after another.

  • Monthly rate with a notice period
  • Named engineers, not a rotating pool
  • You set the order

/ Security and compliance

Checked by auditors, not just promised by us.

Information security
