Custom App Development Company in Australia
Software built around how your business actually works, not the other way around.
Off-the-shelf software is fine until it isn't. You start bending your process to fit the tool, paying for features you never touch, missing the ones you need, and stitching three subscriptions together with spreadsheets and manual data entry. At some point the workarounds cost more than the thing they were meant to save you.
EG Digital is a Melbourne-based custom app development company that builds software around your business: mobile apps, web applications, and full platforms, engineered to fit your workflow and connect to the systems you already run. We are part of Eloma Group, so your build sits alongside cloud hosting, custom software, Microsoft integrations, cyber security, and SEO under one roof. What we ship is not a stranded island. It talks to your backend, it stays secure, and it keeps working long after go-live, because the same team that built it is the team that keeps it running.
One partner scopes it, designs it, builds it, ships it, and maintains it. You own what we build, source code included. One number to call.
Tell us what you want to build and we will give you a real number and a real timeline, not a vague range.
Why choose EG Digital for custom app development in Australia
Built for your business, and yours to keep
Anyone can wire together a no-code builder, drop your logo on a template, and call it custom. We write clean, efficient code around your actual requirements, whether that is a native mobile app, a cross-platform build, or a full-stack web platform with its own backend. Clean code means fewer crashes, faster performance, easier updates, and software your own team can maintain after launch. You own the source code. No vendor lock-in, no licence you have to keep renewing to use your own tool.
One team for the app, the backend, and everything around it
Nearly every custom build needs a web application behind the scenes: an API, a database, authentication, an admin dashboard. Because EG Digital also handles custom software, cloud infrastructure, and security, the parts of a project that usually get handed to a third party and quietly go wrong are all handled in one place. No finger-pointing between an app studio, a backend contractor, and a hosting company when something breaks.
Scalable mobile app solutions, secure from the first line
Software that works for a hundred users and falls over at ten thousand was built wrong. We architect for the load you are heading toward and build security in rather than bolting it on afterward. With cyber security engineers on the same team, data protection, encryption, and Australian Privacy Act obligations are part of the build, not something you discover in an audit later. That matters more in 2026, with new Privacy Act transparency rules and the Cyber Security Rules affecting software that handles personal data.
Honest pricing and clear timelines
We quote from your actual requirements and itemise what you are paying for. You will know the scope, the price, and the timeline before we start, and you will not get ambushed by costs that were always coming. No open-ended retainers that never resolve into a working product. No "it depends" that never turns into a number. And if off-the-shelf is genuinely the cheaper, better answer for you, we will tell you that instead of selling you a build.
Our custom app development services
We are a full-service custom app development company, so you can hand us the whole project or the single piece you are missing.
Custom mobile app development
Native iOS and Android apps, or cross-platform builds in Flutter and React Native, designed around your users and your business rather than forced into a generic template. We handle the whole build: strategy, UX and UI design, front-end, backend, integrations, testing, and store submission. Suitable for launching a new product, digitising an existing process, or replacing an app that has outgrown its original build.
Custom web application development
The tools your business runs on but can't buy off a shelf: client portals, booking and quoting systems, dashboards, admin panels, and full platforms with user accounts, roles, and workflows. These are the apps that replace the spreadsheets, shared inboxes, and generic SaaS tools that never quite fit, and they usually cost less to build and maintain than native mobile apps.
Custom enterprise software in Australia
For larger organisations, we build software that connects to internal infrastructure, enforces proper security and access control, and handles real user volumes without buckling. Complex integrations, multiple user roles, compliance requirements, and accountability at scale are normal territory for us, and having cloud and security engineers on the same team is where these projects are won or lost.
B2B mobile app development
For internal tools, customer portals, and field apps, the software has to fit how your organisation already works and connect to the systems you already run. We build B2B mobile apps and platforms that integrate with your CRM, ERP, and Microsoft stack, handle multiple stakeholders and user roles, and stand up to the scrutiny a business-critical tool attracts.
SaaS platform development
When your product runs in the browser as well as, or instead of, on a phone, we build it: full SaaS platforms with subscriptions, multi-tenancy, and the backend to support them. The line between "app" and "platform" is one we cross comfortably.
MVP development for startups
Speed matters when you are proving an idea. We build custom MVPs that get you to market quickly with a focused feature set, then expand as you validate and scale. Because we also do software and cloud, we can take you from a working prototype to a revenue-ready product without changing teams along the way.
Integrations and APIs
A custom app rarely stands alone. We connect yours to the tools that run your business: CRM, ERP, Microsoft 365 and Dynamics, payment gateways, booking systems, Xero, MYOB, and more. This is where a lot of builds quietly fall apart, and where having software and cloud engineers on the same team pays off.
Maintenance, hosting, and support
Custom software is not "done" when it ships. Your business changes, operating systems update, and users expect fixes and new features. We host, monitor, update, and secure what we build, so it stays fast, compatible, and safe long after launch. One team that knows your software, on call when you need them.
Benefits of custom mobile applications
Off-the-shelf works for commodity functions. Custom earns its cost when the software is close to how you actually make money.
It fits your process instead of reshaping it
A custom app is built around your workflow, so your team stops working around the tool's limitations and stops doing by hand what the software should do for them.
You own it
No per-seat licences that climb as you grow, no features locked behind a higher tier, no dependence on someone else's product roadmap. The source code is yours, and so is the data.
It connects to what you already run
Instead of exporting and re-importing between disconnected SaaS tools, a custom build talks directly to your CRM, accounting software, and internal systems, so data lives in one place.
It scales on your terms
Custom software grows with the business rather than forcing a migration when you outgrow a plan.
The maths turns in your favour
Custom usually costs more than a SaaS subscription in year one. The crossover, where owning beats renting, typically lands around year two or three, sooner if your stitched-together tools already cost four figures a month or your team loses real hours to manual data entry between systems.
Who we build for
Startups
When you are proving an idea, you need to get to market fast without burning your runway. We build custom MVPs and startup apps that ship quickly, then grow as you validate. Because we also do software and cloud, we take you from prototype to a working, revenue-ready product without switching teams partway through. Custom mobile app development for startups that scales with you, not against you.
Small businesses
You need software that does real work without a budget that swallows your year. We build practical, focused custom apps for small businesses across Australia, with clear pricing and no padding. Start with what you need now, built to grow rather than forcing a rebuild in twelve months.
B2B and corporate businesses
For internal tools, customer portals, and field apps, the software has to fit your organisation and connect to the systems you already run. We build B2B and corporate apps that integrate with your CRM, ERP, and Microsoft stack, handle multiple user roles, and stand up to the scrutiny a business-critical tool attracts.
Established and enterprise businesses
For complex software, multiple integrations, and higher stakes, you need a team that can handle scale and stay accountable for it. We bring the engineering depth, the security posture, and the project management to deliver large-scale custom software that holds up, with one partner answerable for the whole thing.
How we work
Discovery and scope
We start by understanding your business, your users, and what the software actually has to achieve, including which systems it needs to connect to. You get a documented scope, a fixed quote, and a timeline before any code is written. No vague briefs that balloon later.
Design and prototype
We design the flows and interface around your users and your goals, then build a clickable prototype so you can react to something real before we commit to the build. Fixing a screen in design is cheap. Fixing it in code is not.
Development
We build with clean code, in fortnightly sprints, with the backend, integrations, and security baked in from the start. A working first version lands early and your team starts using it, so what we build next is shaped by real use rather than guesswork. You see progress at the end of each sprint, not a black box until launch.
Testing and launch
Before anything ships, we test across devices, browsers, and operating systems, check performance and security, and run user acceptance testing. Then we deploy, submit to the app stores where relevant, and stay with you through go-live.
Support and growth
After launch we host, monitor, and maintain the software, and because SEO, digital marketing, and software all live in the same team, we can keep improving and growing the product rather than handing you the keys and walking away.
Custom app development cost in Australia
The honest answer is that it depends on what you are building, and any company quoting a flat price before understanding your project is guessing. Here is the current Australian market for context.
A simple custom app, internal tool, or MVP with a focused feature set typically runs $30,000 to $80,000. A mid-complexity build with multiple user roles, integrations, and a custom backend usually lands between $80,000 and $150,000, and larger platforms climb from there. Enterprise custom software connected to internal infrastructure, with advanced security and multiple integrations, commonly starts around $150,000 and can reach $350,000 and beyond. Australian developer rates generally sit around $150 to $200 an hour, which reflects local salaries, quality assurance standards, and compliance expectations rather than better code by default.
Three things worth knowing. First, the biggest cost driver is functionality, not screen count: integrations, real-time features, custom logic, and multiple user roles are what move the number. Second, the right comparison is not custom versus a monthly SaaS fee, it is custom versus the total cost of your current setup over three years, including licences, manual work, and the growth you can't capture with tools that don't fit. Third, compliance is a real line item in 2026, particularly with Privacy Act changes affecting software that handles personal data, so building it in early is cheaper than retrofitting it later. Eligible builds may also qualify for the R&D Tax Incentive, which can offset a meaningful share of the cost.
On top of the build, budget for hosting and ongoing maintenance, which typically runs 15 to 20 percent of the build cost each year. We quote all of it up front so nothing ambushes you. You get an itemised scope and a real number, not a "from $X" asterisk.

Frequently asked questions
How much does custom app development cost in Australia?
Most custom apps in Australia fall between $30,000 for a simple build or MVP and $150,000 for a mid-complexity platform with multiple user roles, integrations, and a custom backend, while enterprise software commonly starts around $150,000 and can reach $350,000 or more. Local developer rates generally sit around $150 to $200 an hour. The honest version is that price tracks functionality far more than screen count, so the right number depends on what your software has to do and what it connects to. We quote from your actual requirements and itemise it, so nothing surprises you later.
Is custom software worth it compared to off-the-shelf?
It depends on how close the software is to how you make money. Off-the-shelf is the better call for commodity functions, and we will say so if that fits you. Custom earns its cost when a generic tool forces you to dilute what makes you different, when you are losing real staff hours to manual work between disconnected systems, or when compliance and integration needs are non-negotiable. The right comparison is not custom versus a monthly subscription, it is custom versus the total cost of your current setup over three years. For many businesses, custom pays for itself somewhere around the 12 to 24 month mark.
Do I own the source code you build?
Yes. Everything we build is yours, source code included. There is no vendor lock-in and no licence you have to keep renewing to keep using your own software. That means your own team, or any other developer, can maintain and extend it later, though most clients stay with us because the team that built it is the team that supports it.
Can you build a custom app that connects to our existing systems?
Yes, and it is one of the main reasons custom is worth it. Most builds we do integrate with tools you already run: CRM, ERP, Microsoft 365 and Dynamics, payment gateways, accounting software like Xero and MYOB, and third-party APIs. Integrations are designed as part of the build, not bolted on afterward, so your data lives in one place instead of being exported and re-imported between systems.
How long does custom app development take?
For a focused custom app or MVP, plan on roughly two to four months from kickoff to launch. A mid-complexity platform with multiple integrations and user roles runs closer to three to six months, and a large enterprise build can take longer, delivered in phases so you are never waiting months with nothing to show. Timelines depend on scope and on how quickly decisions and feedback come back from your side, which is why we agree on scope and process before we begin rather than promising a date we cannot hold.
