Hiring a Developer vs. Working With Kairos: The Real Cost Comparison
A full-time developer costs far more than the salary line suggests. A freelancer carries its own risks. Here is how the numbers actually compare.
The true cost of hiring a developer
When business owners think about building custom software, the first instinct is often: why not just hire a developer? The salary number looks manageable compared to a six-figure software project. But the salary is only part of the picture — and not always the biggest part.
Here is what a developer hire actually costs per year:
| Cost Item | Estimate |
|---|---|
| Base salary (mid-level developer) | $90,000–$130,000 |
| Benefits (health, dental, 401k match) | $15,000–$25,000 |
| Payroll taxes (employer share) | $8,000–$12,000 |
| Equipment, software licenses, tooling | $3,000–$5,000 |
| Management time (onboarding, reviews, 1:1s) | $8,000–$15,000 |
| Recruitment and hiring cost (amortized) | $5,000–$10,000 |
| Total Annual Cost | $129,000–$197,000+ |
Before a single line of code is written, you are looking at $130,000 to $200,000 per year — and that is for one developer. For most software projects, one developer is not enough. You need design, QA, and architecture decisions beyond what a single hire can reasonably provide.
The freelancer alternative
Freelancers look like a cheaper path. No benefits, no long-term commitment, pay only for what you need. But freelance engagements carry risks that business owners discover the hard way:
- Availability: good freelancers are always in demand. When your project hits a critical phase, they may be unavailable.
- Quality consistency: no vetting process, no institutional knowledge, no code review. You are betting on one person.
- Scope creep: hourly billing with no fixed scope means the cost is unpredictable from week to week.
- Handoff gaps: when the engagement ends, you have code and no ongoing support. Updates, bugs, new features all require finding someone new.
- No accountability structure: a freelancer has no team backing them up. If they get sick, go quiet, or take a better client, your project stalls.
The Kairos model
Working with Kairos is not like hiring one person. It is like engaging a focused, experienced team that has built and delivered software for 20 years — without the HR overhead.
Here is what the Kairos model actually includes:
- Fixed price established before work begins — no billing surprises.
- A scoped estimate that defines exactly what will be built.
- AI-assisted development that compresses delivery timelines.
- Ongoing support through Care plans — not an abandoned codebase.
- No HR: no onboarding, no reviews, no benefits administration, no recruitment.
- Access to a team — not a single developer working alone.
Head-to-head comparison
| Factor | In-House Developer | Freelancer | Kairos |
|---|---|---|---|
| Annual cost | $130K–$200K+ | Unpredictable hourly | Fixed project price |
| Predictable budget | No | No | Yes |
| Ongoing support | Yes (costly) | Rarely | Yes (Care plan) |
| Team depth | Single hire | Single person | Full team |
| HR overhead | High | Low | None |
| Speed to start | Weeks to hire | Days | Days |
| Accountability | Direct but complex | Limited | Contractual, fixed scope |
For most small and mid-size businesses building a specific piece of software, the Kairos model delivers more — with less risk, less overhead, and a clearer budget — than either of the alternatives.
