The short answer
The freelancer vs agency vs in-house decision comes down to how long the work lasts and who on your side can lead it. Hire in-house when software is core to your business and you need it built and changed continuously for years. Use a freelancer or contractor for a well-defined piece of work you can manage yourself. Use an agency when you need a complete team for a project with a start and an end, without the cost and delay of hiring. In Sydney, a senior employee costs roughly $120 to $135 per productive hour once on-costs are counted, a senior contractor $100 to $140, and an agency $120 to $250 (AUD, ex GST).
Key takeaways
- A $165,000 senior salary costs an employer about $203,000 a year once super, payroll tax, insurance and equipment are added, or roughly $120 per productive hour after leave.
- Senior contractors in Sydney bill about $800 to $1,100 a day ex GST; Sydney freelancers often quote $80 to $150 an hour; Australian agencies commonly bill $120 to $250 an hour.
- The hourly rate is the least important number. Continuity, management overhead and who owns the code matter more over the life of a system.
- Under the Copyright Act 1968, employers own code employees write in the course of employment, but contractors and agencies own theirs unless it is assigned in writing.
- Many businesses end up with a hybrid: an agency builds the first version, then an in-house engineer takes over with the agency on call.
Freelancer vs agency vs in-house developers: which is right for you?
The right model depends on how long the work lasts, how central software is to your business, and how much management time you have. None of the three is best in general. Each is cheapest in a particular situation and expensive outside it.
| Freelancer or contractor | Agency | In-house employee | |
|---|---|---|---|
| Typical Sydney cost (AUD, ex GST) | Freelancers $80 to $150/hr; senior contractors $800 to $1,100/day | $120 to $250/hr blended, larger firms higher | About $120 to $135 per productive hour for a senior engineer, fully loaded |
| Time to start | Days to weeks | Two to six weeks | Often three months or more |
| Skills you get | One person’s skills | A team: engineering, design, QA, DevOps, project management | What you hire, one person at a time |
| Management load on you | High: you direct the work | Low to medium: they manage delivery | High: you manage people and careers |
| Continuity risk | High: one person, may move on | Medium: depends on handover and documentation | Low while they stay; high when a sole engineer resigns |
| Best for | Defined tasks, specialist skills, extra capacity | Projects with a start and end, building v1 | Core product, continuous change, long horizon |
| Code ownership by default | Contractor owns it unless assigned in writing | Agency owns it unless assigned in writing | Employer owns work done in the course of employment |
The rate figures come from Robert Walters’ 2026 salary guide, Re:Sourced’s 2026 contractor rate guide (Sydney senior engineers $800 to $1,100 a day), Software Co’s Sydney figures for freelancers, and Conduct’s 2026 agency ranges. Our developer rates guide breaks these down by role and city.
What does an in-house developer really cost?
A senior developer on a $165,000 salary costs an employer roughly $203,000 a year, which works out at about $120 to $125 per productive hour. Salary is only the starting point. Here is the arithmetic for a Sydney senior backend engineer at the midpoint of Robert Walters’ NSW range ($150,000 to $180,000).
| Cost item | Basis | Annual cost (AUD) |
|---|---|---|
| Base salary | Robert Walters NSW senior backend midpoint | $165,000 |
| Superannuation | 12% super guarantee (from 1 July 2025) | $19,800 |
| Payroll tax | 5.45% of wages including super, only if your NSW payroll exceeds the $1.2 million threshold | $10,072 |
| Workers compensation | icare NSW 2026 to 2027 rate for computer consultancy, 0.218% of wages | $360 |
| Equipment, software, training | Assumption: laptop, licences, courses, conference | $8,000 |
| Total employer cost | $203,232 |
Now the hours. A full-time year is 52 weeks of 38 hours. Take out 4 weeks of annual leave, 10 days of personal and carer’s leave (the National Employment Standards entitlement), and about 10 public holidays, and you have roughly 44 working weeks, or 1,672 hours.
$203,232 ÷ 1,672 hours = about $122 per productive hour, before recruitment fees, management time, office space and the months it takes to hire. It’s also before the ramp-up period: a new engineer is rarely fully productive in the first two to three months.
If your business sits under the payroll tax threshold, the figure drops to around $115. If you need a lead or architect (Robert Walters puts NSW solution architects at $195,000 to $220,000), it rises well above $140.
When is hiring in-house the better choice?
Keep development in-house (rather than outsourcing it) when software is a permanent part of how you compete and there’s enough continuous work to keep at least two engineers busy for years. An employee builds knowledge of your business that no outside party can match, and per productive hour they’re usually cheaper than an agency.
In-house makes sense if:
- You’re building a software product, or software is central to operations, with a multi-year roadmap.
- You can hire at least two engineers, or one plus an external partner, so knowledge doesn’t live in one head.
- You have someone who can lead engineering: set standards, review code and hire well.
- You’re prepared for the recruitment timeline and the cost of a bad hire.
The common failure mode is the sole in-house developer. One person carries every system in their head, has nobody to review their code, and when they resign the business is exposed. If you can only justify one hire, pair them with an agency or senior contractor for review and cover.
When is a freelancer or contractor the better choice?
Use a freelancer or contractor when you know exactly what needs doing and can direct the work yourself. You pay only for the hours used, you can get specialist skills quickly, and there’s no long-term commitment.
Good fits:
- Adding capacity to an existing team that already has technical leadership.
- A specialist job: a performance fix, a security review, a specific integration.
- A small, well-specified build, such as a Shopify customisation or a single integration.
- Covering parental leave or a gap while you hire.
Where it goes wrong: a single freelancer building a whole business system with nobody technical on your side checking the work. You carry the project management, the design decisions, the testing and the continuity risk. Also watch the legal edges. Since 26 August 2024, whether someone is a contractor or employee is decided by the whole of the relationship in practice, so a long-running “contractor” working fixed hours under your direction may legally be an employee.
When is an agency the better choice?
Use an agency when you need a whole team for a defined project, fast, without building an engineering function. You get engineers, design, testing, DevOps and project management together, and the agency absorbs the cost of people between projects, sick leave and turnover.
Agencies fit best when:
- You’re building a first version and don’t yet know whether you’ll need a permanent team.
- The project needs several skills at once for three to twelve months.
- Nobody in-house can lead engineering or judge technical quality.
- You want a fixed price or a clear budget rather than an open-ended headcount cost.
The honest downsides: the hourly rate is higher, you’re one client among several, and a poor agency can leave you with code nobody else understands. That last risk is manageable. Insist on code in your own repository from day one, documentation, and written IP assignment. Our guide on how to choose a software development company covers what to check.
If you want agency engineers working inside your team under your direction, that’s staff augmentation, which sits between contracting and a project engagement.
Who owns the code under each model?
Employees’ work belongs to the employer automatically; contractors’ and agencies’ work does not. Under section 35(6) of the Copyright Act 1968, copyright in a work made by an employee under a contract of employment belongs to the employer. There’s no equivalent rule for contractors or agencies: the author owns copyright unless it’s assigned, and section 196(3) says an assignment has no effect unless it’s in writing and signed by or on behalf of the assignor.
Moral rights are separate. Under the Act they can’t be assigned at all, so good contracts include the author’s written consent to the kinds of changes you’ll make to the code. Our contract checklist covers IP assignment, moral rights consents and source code access in more detail.
Should you hire a developer or use an agency? A decision guide
Start from the length and shape of the work, then check who on your side can lead it. If nobody internally can judge technical quality, rule out a lone freelancer first, whatever the rate. If the work will never really stop, rule out a pure project engagement. What remains is usually obvious.
| Your situation | Best fit |
|---|---|
| Continuous product development for 3+ years, can hire 2+ engineers | In-house, possibly with an agency for peaks |
| One-off project, 3 to 12 months, no engineering lead | Agency |
| Existing tech team needs an extra pair of hands or a specialist | Contractor or staff augmentation |
| Small, well-specified task, you can check the work | Freelancer |
| First version of a new product, future team size unknown | Agency to build, then hire and hand over |
| Only one developer affordable, system is business-critical | One hire plus an external partner for review and cover |
How All Webbed Labs fits in
We’re an agency, so the honest advice above applies to us too: if you have years of continuous work and can build a team, hire. Where we fit is building a first version or a defined project with senior engineers only, then handing over cleanly. Code lives in your repository from day one and IP transfers on completion, so an in-house team can take over without starting again. We also provide engineers into existing teams through staff augmentation. See our custom software development service.
Frequently asked questions
Is it cheaper to hire a developer or use an agency?
For continuous, long-term work, an employee is usually cheaper per productive hour. For a project of three to nine months, an agency is often cheaper overall because you avoid recruitment time, a mismatch of skills, and paying for people between projects. The comparison only works when you count the full employer cost and the management time you'll spend.
Should I outsource software development or keep it in-house?
Keep it in-house when software is a permanent competitive advantage and there's continuous work for at least two engineers. Outsource to an agency or contractors when the work is a project with an end date, when you need skills you can't hire quickly, or when nobody internally can lead engineering. Many businesses outsource the first version and bring the ongoing work in-house later.
What are the pros and cons of hiring a freelance developer?
The pros are a lower hourly rate than most agencies, a fast start, specialist skills on demand and no long-term commitment. The cons are that you manage the work yourself, you get one person's skills rather than a team, nobody reviews their code unless you arrange it, and the project stalls if they get sick or move on. Freelancers work best when someone technical on your side can direct and check the work.
Is a contractor cheaper than an employee?
Per productive hour, a senior Sydney contractor at $800 to $1,100 a day (about $100 to $140 an hour) costs roughly the same as a fully loaded senior employee at about $120 to $135. The difference is flexibility: you pay a contractor only for the days you use, with no leave, super or recruitment cost, but you also lose the long-term knowledge an employee builds.
Who owns the code a freelancer writes for me?
Unless there's a written assignment, the freelancer generally does. Section 196(3) of the Copyright Act 1968 says an assignment of copyright has no effect unless it is in writing and signed by or on behalf of the assignor. Make sure the contract assigns IP to you and includes moral rights consents; our contract checklist explains what to look for.
Can I treat a long-term contractor like an employee?
Be careful. Since 26 August 2024 the Fair Work Act uses a whole of relationship test, looking at how the arrangement works in practice, not just the contract wording. A contractor working fixed hours under your direction for years may legally be an employee. Get advice before setting up long-running contractor arrangements.
How long does it take to hire a senior developer in Australia?
Plan for several months from job ad to productive work once you include sourcing, interviews, notice periods (often four weeks or more for senior people) and onboarding. An agency or contractor can usually start within weeks.
What about offshore freelancers?
Offshore rates are much lower, and good offshore developers exist. The trade-offs are time zone overlap, communication, IP enforcement across borders and, if personal information is involved, your obligations under APP 8 of the Privacy Act. Our onshore vs offshore guide covers this in detail.
