Service · Custom software & AI

Custom software and AI applications for mid-sized companies.

When standard software doesn't fit, we build the application that truly reflects your processes. A small, experienced team, AI-supported in planning and delivery - and responsible for operations afterwards.

Building blocks

What we build and take responsibility for.

  1. Business applications

    Software for your core processes - where standard solutions reach their limits.

  2. Customer and partner portals

    Self-service, documents and communication in one place.

  3. Configurators

    Put together products and variants clearly, connected to your systems.

  4. Web and mobile apps

    Applications for browser, iOS and Android from a single source.

  5. AI assistants on your own data

    Answers from your content - for website, sales, service and internal use.

  6. AI-supported process automation

    Process documents, data and interfaces to ERP, CRM and DAM automatically.

  7. AI in existing software

    Add AI features to existing applications without rebuilding them.

  8. Modernisation

    Move legacy systems step by step onto a modern foundation.

Approach

We start where you are.

  1. 1Understand

    Clarify what exists, goals and constraints.

  2. 2Plan

    Define architecture and steps, make effort transparent.

  3. 3Build

    In short iterations, AI-supported, with visible interim results.

  4. 4Operate

    Hosting, support and further development for years.

Team within your team or extended workbench - you decide how we work together.

From our products

Ospitra Nexus

For our own product Ospitra we built Nexus: hotels become discoverable for AI assistants, availability is checked automatically, and concrete requests go straight to the hotel. We bring the same experience into client projects.

Frequently asked questions

  • Who develops custom software for mid-sized companies?

    billiton has been developing custom software for mid-sized companies since 1994: business applications, customer and partner portals, configurators, and web and mobile apps. An experienced team builds the software and keeps running it for years.

  • Custom software or off-the-shelf software - which pays off?

    Custom software pays off when your processes are a competitive advantage or standard software only fits with many workarounds. We first check whether an existing solution is enough - and tell you if it is.

  • Who takes over existing software and develops it further?

    We also take over applications built by others: we review code, data and operations, stabilise the foundation and develop it further step by step. A complete rebuild is rarely necessary.

  • Are there developers who work as an external team within our team?

    Yes. We work as a team within your team, with your people and tools, or as an extended workbench delivering finished software. You decide how closely.

  • Who runs and maintains custom software after go-live?

    We do, if you wish: EU hosting, maintenance, support and further development for years - by the same people who built the software.

Let's talk about your project.

A new system, an AI application or an application that needs to be developed further.
