Agency vs freelancer for your software project
When a freelancer is the right call (fast and cheap) and when you need an agency (covered risk, process, continuity).
The most expensive decision early in a project isn't the stack — it's who you hire. A good freelancer delivers fast and cheap; a bad one disappears mid-project. An agency costs more but the risk is covered: if someone quits, the project continues. This is what we learned rescuing abandoned projects.
Freelancer
Option AA single independent developer. Cheaper, faster if everything goes right.
- Lowest price (no agency overhead)
- Direct communication with the person building
- Schedule flexibility — can pivot quickly
- Good for one-off tasks or standalone features
- If they quit or get sick, the project stops
- Limited to ONE discipline (full-stack is rare, frontend+backend+devops rarer)
- No documented process — all in their head
- No real post-delivery guarantee (if they disappear, no one to claim against)
- Bus factor = 1
Agency (Sirius)
Option BMulti-discipline team with process. More expensive but risk is covered.
- Bus factor > 1: if one is absent, the project continues
- Multi-discipline stack: frontend + backend + devops + design + QA
- Documented process: weekly sprints with demos, retros, runbooks
- Contractual post-delivery guarantee (30 days minimum)
- We bill per deliverable, not per hour → closed budget
- Continuity: the project lives in the client's repo, not on a personal laptop
- Higher price than a single freelancer
- Communication overhead: you go through a PM instead of talking direct to the dev
- Less flexibility for last-minute scope changes

03/The honest verdict
The most common trap: hiring a cheap freelancer for a USD 10,000+ project. The initial savings are lost 3x when they quit in week 5 and you have to rescue the project with another team (which has to redo 60% of undocumented code). For small projects < 4 weeks with clear scope and an internal tech team to take over, freelancer is excellent. For everything else, the cost of having no bus factor ends up being higher than the extra agency price.
04/Frequently asked questions
Frequently asked questions
How much does a freelancer cost in Costa Rica?▾
Typical rates: junior USD 15–25/hour, mid USD 25–45/hour, senior USD 45–80/hour. For full projects: USD 2,000–8,000 depending on scope and freelancer's speed.
How to prevent a freelancer from abandoning?▾
Written contract with payment milestones (40% start / 30% midway / 30% final), code in YOUR repo from day 1 (not on their computer), and verifiable references from 2–3 previous projects of similar size. If the freelancer refuses any of these, find another.
When is an agency not worth it?▾
For tasks < 40 hours (minor changes, one-off integrations), an agency is overhead. Better a recommended freelancer or your internal team. The agency wins when there's multi-discipline scope and/or a product that operationally affects your business.
Is Sirius a small agency? Isn't that as risky as a freelancer?▾
We are a team of 5+ devs with shared processes. If one is absent, another takes over — the code lives in shared repos, not on individual computers. The difference vs freelancer is not size, it's continuity: no project depends on ONE person.
