Custom Software Development Services in Australia

When the workaround becomes the workflow.

Most organisations reach a point where their software shapes their process rather than the other way round. Devika builds custom software around how your business actually operates, on infrastructure you own.

The Shadow System Nobody Budgeted For

Every organisation running off-the-shelf software eventually builds something around it. A spreadsheet that reconciles what two platforms disagree about. A weekly export and re-import that somebody owns. A rule everyone follows that is not written anywhere, because the software cannot express it.

None of that appears on a budget line. It is absorbed as headcount, error rate and delay, and it is invisible precisely because nobody invoices for it. Most finance teams are surprised by the number when they finally add it up.

The good news is that it is measurable, and once it is measured the decision usually makes itself. Custom software exists to remove that cost. We build bespoke software for business workflows: systems shaped around how your organisation operates, rather than how a vendor in another country assumed it might.

The spreadsheet holding two systems together is custom software. You are just maintaining it by hand.

Custom or Off-the-Shelf: An Honest Comparison

We will talk you out of custom software when off-the-shelf is the right answer. That happens more often than you would expect from a development company.

Off-the-Shelf Wins When

Your process is genuinely standard, the licence cost is predictable, and the vendor’s roadmap is heading where you are heading. Payroll, general accounting and CRM are usually solved problems. Rebuilding them is expensive theatre.

Buy commodity. Build advantage. Never the other way round.

Custom Wins When Any of These Are True

Custom software solutions earn their cost when the standard product is the thing getting in the way. In practice that means one or more of the following is true.

  • The workflow is the competitive advantage, and standardising it means giving it up
  • You are paying for three platforms and using 15 per cent of each
  • Per-seat licensing means growth is punished rather than rewarded
  • Your data lives in silos that do not talk, and integration keeps failing
  • Compliance, sovereignty or audit requirements that vendors will not meet
  • Manual handoffs between systems cost measurable staff hours every week, where automation would pay for itself

What Scalable and Secure Actually Mean Here

Two words that appear on every proposal. Here is the substance.

01

Scalable

Serverless means you rent the compute by the second instead of renting the server by the month. If your system is busy in bursts, that cost line nearly disappears. If it runs flat out all day, it will not.

Scalable custom software solutions handle 10 times the load without a rebuild and, the part usually left out, cost roughly proportionally when they are not under load. Traditional architecture bills you for capacity whether you use it or not. Serverless architecture bills for what you consume.

The difference is not theoretical. When we rebuilt Circolo on serverless infrastructure, their monthly AWS bill for compute, storage and data transfer fell from over $2,000 to under $1, because an events platform sits idle most of the month and they had been paying for peak capacity continuously. Reliability and performance improved at the same time. Your own saving depends entirely on your usage pattern, and a system under constant load will see far less.

02

Secure

Security in practice means encryption in transit and at rest, role-based access so people see only what their job requires, audit logging, dependency patching, and infrastructure managed under AWS shared responsibility and its compliance programs. We test against the OWASP Top 10 and can arrange independent penetration testing on request.

We are 100 per cent onshore, which matters when data residency is a board-level question. Data stays in Australian AWS regions unless you direct otherwise, and no engineer outside Australia touches your systems.

Ask us for our current certification and insurance position before you go to contract. We would rather tell you exactly what we hold than imply more than we do.

Enterprise Software, Without the Enterprise Timeline

Enterprise software has a reputation for 18-month programs that deliver something already obsolete. That reputation is earned, and it is avoidable.

We work in short sprints with working software at the end of each one. You see progress in weeks, not at a launch date. Scope adjusts as reality intrudes, which it always does.

How We Work

  1. 01

    Discovery and Architecture

    We map the current workflow including the workarounds, because the workarounds are where the requirements are hiding. A solution architect owns the technical shape. The output is a scoped roadmap with sequencing and cost.

  2. 02

    Foundation on Baseline

    For business systems, Baseline contributes the things every platform needs and no user ever praises: authentication and single sign-on, role and permission management, audit logging, payments and an admin console. On a typical enterprise build that is 8 to 12 weeks of work you do not fund twice.

  3. 03

    Iterative Build

    Two-week cycles, working software each time, and direct access to the people building it.

  4. 04

    Launch and Scale

    Phased rollout, monitoring, and a team that stays available through support and maintenance.

Two-week cycles. Working software every fortnight. You never wait six months to find out it is wrong.

What Your CTO Will Ask

  1. 01

    Architecture

    Serverless AWS by default, with containers where workload shape warrants it. Infrastructure defined as code so environments are reproducible.

  2. 02

    Testing

    Automated unit, integration and end-to-end coverage on critical paths, with test results gating deployment.

  3. 03

    Pipelines

    CI/CD with staged environments, automated rollback and no manual production deploys.

  4. 04

    Documentation and Handover

    Architecture decision records, API documentation, environment runbooks and a written handover pack. You should be able to move the system to another team without our cooperation.

  5. 05

    Key-Person Continuity

    Every engagement has at least two engineers familiar with the codebase, and repository and infrastructure access sits with you from day one.

Why Not Offshore

This is the first question most finance teams ask, and it deserves a direct answer rather than a slogan.

Offshore development will beat our hourly rate, often by half. What the rate card does not price is the specification detail required to brief across a timezone gap, the rework when that detail proves insufficient, the review overhead on your side, and the practical difficulty of enforcing anything across jurisdictions if a project goes wrong.

Our engineers are Australian employees in your timezone who join your standups and speak to your staff directly. On a complex build with changing requirements, the total delivered cost is usually far closer than the rates suggest, and the variance is much lower.

If your project is genuinely well-specified, stable in scope and low on integration risk, offshore may be the better commercial answer. We will tell you when we think that is the case.

The Volt Bank app

Volt Bank

  • Digital banking
  • Web and native mobile
  • 2021

In 2021 Devika worked alongside Volt Bank’s technology leadership to consolidate core banking services across web and native mobile, front end and back end, over a 3-month engagement. Volt was one of Australia’s first licensed neobanks. It closed its deposit-taking business in June 2022 and returned its banking licence to APRA in September 2022 after being unable to raise further capital. We include the work here because the engineering standard it was delivered to still represents how we work in regulated environments.

“We had to pick and choose the firms we want to partner with very selectively. Selecting Ken and the Devika team was a great decision.”

The Circolo platform

Circolo

  • Event management
  • Cloud-native SaaS

An event company arrived with a platform that was unreliable, expensive to run and difficult to extend. Devika rebuilt it as a cloud-native application on Baseline and AWS in 3 months, delivering role-based access, live runsheets, budget tracking and Stripe-backed monetisation, and cutting infrastructure cost by more than 99 per cent in the process.

“They challenge us in constructive ways and truly feel like part of our team.”

The EZShip platform

EZShip

  • Logistics operations
  • Serverless AWS

A shipping platform aggregating multiple carriers into one dashboard, with rate comparison, bulk label generation, real-time Shopify fulfilment sync, and an integration-ready API layer built for Amazon, eBay and ERP connections still to come. 3.5 months, now generating commercial revenue.

Common Questions

How do we know custom is the right call?

Discovery. We will map your workflow and, if a configured off-the-shelf product does the job, we will say so. It is a shorter conversation but a better one.

What does custom software cost?

It varies enormously with scope. The number that matters is total cost of ownership: build plus running costs, set against your current licence fees plus the staff hours absorbed by workarounds. After discovery we quote a fixed band with the assumptions documented, so you can compare proposals on the same basis.

How long before we see anything?

Working software within the first few sprints. Full delivery for a substantial platform typically runs 3 to 6 months.

Who owns it?

You own the application code, the data and the infrastructure outright on completion. The Baseline components underneath it are licensed to you perpetually, irrevocably and royalty-free, with no ongoing fee and no restriction on modifying, extending or selling the product built on them. We use the same wording on every engagement so your procurement team is not comparing two different promises.

What are the commercial terms?

Fixed-scope phases with agreed milestones, a defect warranty period after each release, professional indemnity and public liability cover, and a documented exit and handover process. We will send the standard terms before the second meeting rather than at contract stage.

Can you work with our existing systems?

Yes. Integration is usually the majority of the work in custom software for established businesses.

Do you provide ongoing support?

Yes. Most clients move into an ongoing arrangement at launch, covered by our support and maintenance service.
