Amethyst Nexalune Web Design & Software Development

Custom software

The digital engine of your business.

Custom software built around your workflow: job tracking, inventory, bookings or document checks, so you can spend less time searching through spreadsheets and group chats.

Alongside websites, I build custom business software and internal tools for small companies in Great Yarmouth, Norfolk, and remotely across the UK and Hungary. These include client and document portals, quote trackers, training platforms, job trackers, inventory systems and booking tools. They help replace records spread across spreadsheets, emails and group chats. I design each system around the way your business works. Pricing depends on the work involved. Four working demos are available to try. We start with a free consultation, then I build the system in stages so you can review it along the way.

How I work

From first call to a live system, five steps.


  1. Requirements gathering

    A free consultation to map your actual workflow: what's slow, what's manual, and what the system needs to solve.

  2. Scope & quote

    A written quote and a module-by-module plan, agreed before anything is built.

  3. Design & data model

    I design the database structure and the screens with you, so the system matches how your team actually works.

  4. Build in stages

    Delivered in stages you can review and test as it goes, not one big reveal at the end.

  5. Testing & launch

    Tested with your real data, then launched with training and support afterwards.
