Hire In-House vs. Freelancer Developer

Work through four questions in order. First, do you have product-market fit? If you are still testing what to build, a freelance full-stack developer keeps you flexible — you pay for what ships, not for a seat. Second, how much runway? Under 12 months, a 4–6 month recruiting cycle for a first in-house hire eats a third of it before a line of code lands. Third, is the backlog continuous? A steady 6+ month roadmap justifies a full-time hire; a defined build (MVP, rebuild, a feature push) suits a freelancer. Fourth, do you need web and mobile and backend at once? One in-house hire rarely covers all three; a full-stack freelancer can. If three of four point the same way, that is your answer.

The salary number is the smallest part of an in-house hire. In EU markets a fully loaded engineer runs roughly €70–120k+ once you add taxes, equipment, tooling, and management time, plus a 4–6 month search and months of onboarding before peak output. A freelancer inverts that: fixed scope, no recruiting overhead, no ongoing commitment, and shipping in days rather than months. The trade-off is real — when the project ends, the relationship ends, so continuity for a long-term roadmap is weaker. The honest framing is timing, not quality. A freelancer is cheaper per build; an in-house hire is cheaper per year once the backlog is large enough to keep one person busy indefinitely. Exact figures depend on scope — contact for a quote.

A freelancer wins the 0→1 stage: validating an idea, building an MVP, or rebuilding something that is slowing you down — work with a clear edge and a deadline. Across BookBed (a booking SaaS with bidirectional iCal sync on Flutter, Firebase, and Stripe), Callidus (a clinic SaaS on React and Firebase), and Pizzeria Bestek (React and Supabase), the common pattern is one developer covering the full stack and delivering without agency coordination overhead on comparable scope. The first in-house hire wins after product-market fit, when the roadmap is long enough to keep someone fully occupied and institutional knowledge compounds — knowing why a past decision was made saves real time. Many teams do both in sequence: a freelancer ships the first version, then the first hire takes over maintenance and the next phase.

The most expensive mistake is hiring in-house too early — committing to a full-time salary and a months-long search while you are still discovering what to build, which locks spend before you have proof. The opposite error is leaning on a freelancer past the point where you have a permanent, growing backlog; once one person could be busy year-round, the per-build model costs more than a seat. A third trap is expecting a single in-house generalist to cover web, mobile, and backend at the same depth — that is a freelancer's range, not usually a first hire's. Avoid all three by matching the engagement to the stage: pay per build while the future is uncertain, hire for a seat once it is not. Write down scope before either decision so you are comparing the same work.
