You face a choice every SMB owner with a software project makes at some point. A freelance developer feels faster and cheaper. An agency feels safer and more complete. Both feelings are partly right, and both can cost you money. For the build itself we work with custom platforms or a websites engagement. In this article we put the two options side by side honestly on cost, risk, capacity and ownership.
What is the difference between a freelance developer and a software agency?
- Freelance developer (ZZP in Dutch context). A self-employed individual who invoices you directly. One person, one hourly rate, one direct line.
- Small agency (2 to 10 people). A team that can cover multiple roles (developer, designer, project lead).
- Mid-sized agency (10 to 50 people). Full multi-disciplinary teams.
- Large agency (50+ people). Target audience is usually corporates and public tenders.
According to Dutch CBS figures, the Netherlands has more than 150,000 freelancers active in IT. For broader background see our guide on having custom software built.
When does a freelance developer fit best?
- Small, sharply scoped project. A script, integration or module of 2 to 4 weeks of work.
- Prototype or proof-of-concept. Test whether an idea works before you invest seriously.
- Specialist skill for a short period. iOS mobile app, GIS integration, smart contract.
- Top-up to your own team. Temporary capacity or a specific role.
- Maintenance on an existing application.
When does an agency fit best?
- Multi-disciplinary project. Design, frontend, backend, devops and testing.
- Long-term project of 3 to 12 months.
- Project where downtime really hurts. A customer-facing platform with a go-live deadline.
- Project with multiple stakeholders on the client side.
- Project where you want an SLA and a fix guarantee.
How do costs differ between freelancers and agencies?
| Supplier type | Hourly rate 2026 | MVP project | Platform project |
|---|---|---|---|
| Freelance junior (1-3 yrs) | €55 to €75 | €6,000 to €12,000 | €18,000 to €35,000 |
| Freelance mid (3-7 yrs) | €75 to €95 | €8,000 to €18,000 | €25,000 to €55,000 |
| Freelance senior (7+ yrs) | €95 to €130 | €10,000 to €22,000 | €35,000 to €85,000 |
| Small agency (2-10) | €95 to €135 | €12,000 to €25,000 | €30,000 to €90,000 |
| Mid-sized agency (10-50) | €115 to €165 | €18,000 to €45,000 | €55,000 to €150,000 |
| Large agency (50+) | €135 to €225 | €35,000+ | €100,000+ |
What are the risks with a freelance developer?
- Capacity and single point of failure. One person cannot deliver 60 hours per week.
- Illness and holidays. When the freelancer is sick, the project stops.
- Other clients with deadlines. A larger client can suddenly take priority.
- Exit and knowledge transfer. If a freelancer stops their practice, you are left with a codebase only they understood.
For broader material on code ownership see our article on avoiding vendor lock-in.
What are the risks with a software agency?
- Agency overhead in every invoice. 40 to 60 percent office, sales, marketing.
- Juniors learning on your project. Senior pitches, junior builds.
- Sales layer between you and the builder.
- Account management that bills hours. 10 to 20 percent of the budget can go to management.
The TopDevs model: agency without agency overhead
We are an agency, but we work with a lean senior team to minimise overhead. Founders build along. No sales layer, no project managers. See the Mastone case and the Simply case.
How do you choose between freelancer, small agency and large agency?
| Dimension | Freelancer | Small agency | Mid-sized agency |
|---|---|---|---|
| Project size | Under €20,000 | €15,000 to €120,000 | €85,000+ |
| Lead time | 1 to 8 weeks | 4 wks to 9 months | 6 months to 2 years |
| Multi-disciplinary | No | Yes (3-5 roles) | Yes (all roles) |
| Continuity on dropout | Weak | Good | Strong |
| Sales layer | None | Small or none | Present |
What questions do you ask a potential supplier?
- Who is actually going to build? Demand names and years of experience.
- What is your approach to the discovery phase?
- Do you work with a fixed price per phase or on an hourly basis?
- Do I get the code in ownership in a Git repository under my account?
- What happens in case of illness or sudden death?
- What SLA and fix guarantee do I get after go-live?
- What do I get to take with me on a switch in 2 years? See our terms and conditions.
Which marketplaces do you use for IT freelancers in the Netherlands?
You do not have to search through word of mouth. There are several marketplaces where Dutch IT freelancers actively maintain profiles. Each platform has its own profile in terms of rates, screening and audience, so the choice depends on how sharply you have defined your role and how much self-screening you want to do.
| Platform | Strong side | Weak side | Rate range |
|---|---|---|---|
| Freelance.nl | Many Dutch profiles, open bidding | Little upfront quality screening | €55 to €110 |
| Bawjobs / Bawpro | Good for longer assignments and intermediaries | Often via a middleman, markup of 10 to 25 percent | €75 to €135 |
| Toptal | Pre-vetted senior profiles, English-speaking | Higher rate, no local contact | €95 to €180 |
| LinkedIn ProFinder | Network and referrals as filter | No formal screening | €65 to €130 |
| Malt | Large European supply, transparent reviews | Limited Dutch availability | €70 to €140 |
How do you review a quote from a freelancer versus an agency?
A freelance quote is usually 1 to 2 pages. An agency quote is often 8 to 20 pages. More pages does not automatically mean a better offer. What counts is whether the assumptions, scope limits and risk paragraph are concrete enough to rely on later.
- Assumptions named explicitly. Which API access, which design, which test data is assumed.
- Scope limits in detail. What is explicitly not included, to head off scope creep.
- Fixed price per phase or fixed total. Plan for partial invoices after each milestone.
- Staffing at name level. Who writes the code, not just who pitches.
- Acceptance criteria per deliverable. How do you know something is done.
- Warranty paragraph. What falls under free correction and what counts as extra work.
- Ownership clause. Code, design and deploy scripts in your company name.
A freelancer who refuses to write down scope limits will say after 4 weeks that something fell outside the assignment. An agency that delivers only vague language will invoice the difference later.
How do code review and QA differ between freelancers and agencies?
At an agency, code review is usually part of the standard process. Two pairs of eyes on every pull request, automated tests in a pipeline, and a QA role that signs off independently from the developer. With a freelancer that is rarely set up, simply because there is only one person. That does not mean a freelancer delivers bad code, but the verification layer sits with you or with an external reviewer you arrange.
- With a freelancer: arrange a second pair of eyes yourself. An external code review of 4 to 8 hours per month costs €400 to €800 and catches 80 percent of the sloppy work.
- With an agency: ask about the review process. Who reviews, how often, and can you see example pull requests.
- Both: automated tests from sprint 1. Linting, unit tests and a staging environment are not a luxury.
- Both: a security scan before go-live. OWASP ZAP, Snyk or a manual pentest for sensitive data.
How does a hybrid team with a fixed agency and flex freelancers work?
In practice, most companies that work on software for more than two years end up with a mix. A fixed agency or internal team keeps the core platform running, and a freelancer is brought in as needed for a peak or a specialist skill. That gives you the continuity of an agency with the price flexibility of a freelancer.
- Core with the agency. Architecture, security, deploys and critical features.
- Peak work with a freelancer. Temporary second frontend developer or a data specialist.
- Specialist skills with a freelancer. iOS, machine learning, GIS or integrations with niche systems.
- Ownership in one place. A Git repository under your account, not under the freelancer.
- Single point of accountability. The agency is responsible for the codebase as a whole.
What contractual dos and donts apply with freelancers and agencies?
A solid contract protects both sides and prevents 90 percent of conflicts. Whether you work with a freelancer or an agency, the same paragraphs need to be in there. The difference is in how you fill them in.
| Topic | Freelancer | Agency |
|---|---|---|
| Notice period | 14 to 30 days | 30 to 60 days |
| IP transfer | Per delivery or at final payment | Per phase with milestone payment |
| Confidentiality (NDA) | Yes, mutual | Yes, mutual |
| Non-compete clause | Better avoid, limited supply | Possible by default |
| Right of substitution | Replacement freelancer on dropout | Agency supplies replacement |
| Liability cap | Up to 1x project fee | Up to 1x or 2x project fee |
What do you do if your freelance developer falls ill mid-project?
This is not a theoretical scenario, because it happens regularly. The question is not whether it happens, but whether you have a plan. Without a plan, an 8-week MVP project effectively stalls for 3 weeks after one week of illness, because you also lose handover and ramp-up time.
- Up front: ask for the name of a backup person. Someone in the freelancer network who can step in for at least 20 hours per week.
- Up front: demand a README in the repo. So a second developer can start within a day.
- With illness under 1 week. Shift the planning, keep communication open with client or stakeholders.
- With illness 1 to 3 weeks. Activate the backup or hire a temporary replacement via a marketplace.
- With illness longer than 3 weeks. Run a handover session with the backup, revise the planning, and decide whether to continue or pause.
- With permanent dropout. Stop, audit the code, and pick an agency or new freelancer to finish.
How do international freelance and agency teams compare with Dutch ones?
Teams in Poland, Portugal, India or Latin America are often brought in as a cost saver. Reality is more nuanced. The rate difference is real, but coordination overhead, time-zone gaps and cultural ways of working make the net advantage smaller than the gross numbers suggest.
| Region | Rate range | Strong side | Weak side |
|---|---|---|---|
| Netherlands | €75 to €165 | Same time zone, language, GDPR overview | High rate |
| Poland / Romania | €45 to €90 | Strong seniors, EU time zone, GDPR | English requirement, scarce in July-August |
| Portugal / Spain | €55 to €100 | High English level, EU law | Scarcity in senior roles |
| India / Philippines | €20 to €60 | Low rates, large supply | Time-zone gap, slower communication |
| Latin America | €40 to €85 | Time zone overlaps with Dutch morning | Variable quality, outside EU law |
Three examples of TopDevs clients who switched between freelancer and agency
Theory helps, examples help more. Three short cases from our portfolio in which the choice between freelancer and agency played out in practice. Names anonymised where needed.
- Accounting firm, 12 staff. Started with a freelancer for a 4-week client portal prototype. Went well, but when scope expanded to integrations with Exact and Twinfield it got too complex for one person. Switched to an agency for build and SLA. Costs went up, but dropout risk went away.
- Logistics SMB, 35 staff. Worked for 2 years with a fixed agency. When a 6-week peak project came along, they hired a freelance frontend developer through Bawjobs. The agency PM coordinated, the freelancer built alongside the fixed team. Worked without friction.
- Fashion brand in B2B e-commerce. Started with an agency, was disappointed by pace and the juniors on the project. Switched to two specialist freelancers for a lean rebuild in 10 weeks. For ongoing maintenance they signed an SLA with us.
