01What we do

Yelko is an Australian software company. We build, own and operate our own products, and we engineer custom platforms for organisations that have outgrown generic tools.

We run Finye and Start My Tradie in production every day. That makes us careful in the way an owner is careful: about reliability, maintainability and what the software will need in three years, not just at launch.

The same team designs, builds and looks after custom software for other organisations, from new SaaS platforms to the integrations and modernisation work that keeps established businesses moving.

03Engineering

Serious software for organisations that have outgrown generic tools.

We take on work where the requirements are specific, the systems are connected and the software has to keep running for years. Here is the shape of what we build.

04Problems we solve

Most of our work starts with a sentence like one of these.

  1. We re-key the same information into three different systems.
    We buildIntegrations and a single source of truthData enters once and flows to every system that needs it.
  2. Our core software is fifteen years old and only one person understands it.
    We buildA staged modernisationA maintainable rebuild delivered in phases, with your data migrated and verified.
  3. We’ve outgrown spreadsheets, but no product fits how we work.
    We buildA custom business applicationBuilt around your processes, roles and approvals, not the other way round.
  4. We have an idea for an industry platform, but no engineering team.
    We buildA SaaS product, built to operateMulti-tenant architecture, billing and onboarding, designed to grow from day one.
  5. Our product works, but it’s struggling to scale.
    We buildArchitecture and performance improvementsProfiling, refactoring and infrastructure changes that remove the bottlenecks.

05How we work

A considered process, and no hand-off at the end.

Software is never finished. It is looked after. Our process is built around that, so the last step leads back to the first.

  1. Understand

    We learn the operation, the constraints and the commercial goal before proposing any software.

  2. Architect

    Data model, integrations, security and hosting are designed up front and documented.

  3. Build

    Delivered in short increments you can see and use, with automated tests from the start.

  4. Launch

    Planned cut-overs, data migration and monitoring, so going live is uneventful.

  5. Evolve

    We stay on to maintain, secure and extend the software as your business changes.

06Why Yelko

We run software in production. Every day.

We ask what it’s for first.
We understand the problem before choosing a solution, and we’ll tell you when you don’t need custom software.
Built to be understood later.
Clear data models, tested code and documentation, so the next engineer (including yours) can extend it.
Australian, and reachable.
An Australian company in your time zone, with direct access to the people building your software.
We stay after launch.
Maintenance, security updates and new features are part of the plan, not an afterthought.
