What You Get With Our Custom Software Development Services

🏗️

How do you design software architecture that won't need to be rewritten in 2 years?

We produce a detailed Architecture Decision Record before any code is written — choosing modular, event-driven or microservices patterns appropriate to your scale, with clear boundaries that let you evolve independently without costly rewrites.

How fast can we get a working version of the software to test?

Two-week Agile sprints deliver usable, testable software from week three of the project. You interact with working builds throughout development, giving feedback before the next sprint — not six months later at final delivery.

🔒

How is security built in from day one rather than bolted on later?

Threat modelling runs in the first sprint alongside architecture design. We implement OWASP Top 10 mitigations, secrets management, role-based access control, audit logging, and automated SAST scanning in CI/CD as standard practices.

🔗

Can the new software integrate with our existing tools and databases?

Yes — we integrate with any third-party API, legacy database (MSSQL, Oracle, PostgreSQL), ERP system, or cloud service. We document every integration contract upfront and build adapter layers that decouple your core application from third-party dependencies.

📊

How will we monitor software performance and errors in production?

Structured logging, distributed tracing, and metrics dashboards are built in from day one using Datadog, New Relic, or open-source stacks. Alerts fire before users notice an issue, and you get monthly performance reports throughout the engagement.

🔄

How do software updates get deployed without taking the system offline?

Blue-green deployments and feature flags enable zero-downtime releases. Our CI/CD pipeline automates testing, security scanning, and deployment to staging and production environments — releasing on demand rather than on a fixed schedule.

📱

Can the software be accessed on mobile as well as desktop?

Yes — we build fully responsive web applications that work on any device, or pair the core platform with dedicated iOS and Android companion apps built by our mobile team using the same backend APIs.

☁️

Which cloud platforms do you deploy custom software to?

We deploy to AWS, Google Cloud, and Microsoft Azure. Infrastructure is defined as code using Terraform for consistent, auditable environments. We also support private cloud and on-premises deployment for regulated industries requiring data sovereignty.

02

Architecture Design & Fixed-Price Quote

Our architects design the system architecture, database schema, and API contracts before writing a single line of code. You receive a fixed-price proposal with milestone dates and payment schedule for approval.

03

Agile Development & Continuous Delivery

Two-week sprints deliver working software from week three. You access a staging environment throughout the project, provide feedback each sprint, and approve each milestone before the next begins.

04

Custom Software Development FAQs

Common questions about our custom software development services.

Ask Us Anything →
How much does custom software development cost in Australia?
Custom software development in Australia typically starts from AUD $30,000 for a focused internal tool or MVP and ranges to AUD $500,000+ for complex enterprise platforms. OpenMalo provides a fixed-price quote after a free discovery session — the cost depends on complexity, integrations, and team size required. We offer milestone-based payment schedules to spread investment over the project timeline.
How long does it take to build custom software?
Simple internal tools and MVPs typically take 8–16 weeks. Mid-complexity platforms with multiple user roles and integrations take 4–8 months. Complex enterprise systems can take 9–18 months. We provide a detailed milestone timeline in every proposal, and Agile delivery means you receive working software every two weeks throughout the project.
Do you sign NDAs before discussing our software idea?
Yes — we sign a mutual NDA before any substantive project discussion, typically within one business day of request. All your business logic, data, and technical concepts are fully protected from the first conversation through the entire engagement.
Who owns the code once the software is built?
You own 100% of the source code, intellectual property, and all assets created during the project. Upon final payment, we transfer the full codebase, all CI/CD configurations, infrastructure scripts, and documentation. OpenMalo retains no licensing rights or ongoing dependencies on our proprietary tools.
Can you work with our existing internal IT or development team?
Yes — we frequently work as an augmentation team alongside client internal developers, or hand over to internal teams at specific project milestones. We document all architectural decisions and coding standards clearly to ensure a smooth knowledge transfer.
What if the software requirements change mid-project?
We handle change requests transparently through a formal change control process. Minor changes within scope are often absorbed; significant scope changes receive a revised quote and updated timeline within 48 hours. Nothing changes without written agreement from both parties.
Do you provide software testing and quality assurance?
Yes — every project includes automated unit tests, integration tests, and end-to-end tests written as part of development. Our dedicated QA engineers run structured manual testing each sprint, and we conduct user acceptance testing with your team before any production release.
Can you host and manage the software infrastructure for us?
Yes — we offer managed cloud hosting on AWS, Google Cloud, or Azure with 99.9% uptime SLA, automated backups, security patching, and 24/7 incident response. Managed infrastructure is available from AUD $800/month depending on scale and complexity.
What happens if there are bugs after the software launches?
All projects include a 30-day warranty period post-launch covering bug fixes at no additional cost. Beyond 30 days, we offer support and maintenance contracts from AUD $3,000/month covering bug resolution, security updates, and agreed feature development with a guaranteed response SLA.
Do you have experience building software for regulated Australian industries?
Yes — we have built compliant software for healthcare (My Health Record integration, HIPAA), financial services (APRA, AML/CTF), and government (ISM, Essential Eight, Privacy Act). Our security practices include threat modelling, penetration testing, and compliance documentation tailored to your regulatory requirements.
