The verdict in three sentences
The agency wins on time-to-market and flexibility: it starts in 2-3 weeks, scales up and down without severance cost, and brings an immediate multidisciplinary team. The in-house team costs more to start (recruitment + 3-6 months of ramp-up) but becomes cheaper and holds the domain knowledge when the need is permanent and high-volume. The switch depends on two variables: the duration of the need and the developers' real utilisation rate.
Annual cost: in-house vs agency
Let's compare two in-house developers against an equivalent agency capacity for a Toronto SME (2026 order of magnitude, ex-tax).
| Item | 2 in-house devs | Agency (equivalent) |
|---|---|---|
| Fully loaded salary cost | 110,000-150,000 EUR/yr | — |
| Day rate | — | 450-750 EUR |
| Annual cost (200 billed days) | — | 90,000-150,000 EUR |
| Recruitment | 8,000-20,000 EUR | 0 |
| Ramp-up (3-6 months) | 20,000-40,000 EUR lost | 0 (start in 2-3 weeks) |
| Hardware / licences / workstation | 6,000-12,000 EUR/yr | Included |
| Load flexibility | Low | High |
At constant volume and full time, in-house and agency converge on annual cost; the difference plays out in hidden costs (ramp-up, recruitment, utilisation rate).
Switching thresholds: when to hire, when to outsource
The deciding criterion is real utilisation. An under-used in-house team costs full price; an agency is paid only for days consumed.
| Situation | Recommendation | Costed reason |
|---|---|---|
| Need < 12 months | Agency | Ramp-up (20-40k) not amortised |
| Utilisation < 70% | Agency | In-house paid idle 30% of the time |
| Permanent need + utilisation > 85% | In-house | Amortises recruitment + ramp-up in ~18 months |
| One-off peak + urgency | Agency | Start in 2-3 weeks vs 3-6 months |
| Long-term strategic core | Hybrid | In-house steers, agency reinforces |
Simple rule: under 12 months or below 70% utilisation, the agency is almost always cheaper. Beyond that, with a stable, well-filled need, in-house wins and capitalises the knowledge.

Mini case study
The IT director of an industrial SME in Toronto must ship a business app in five months. In-house option: hire two devs (EUR 130k/year loaded) + EUR 15,000 recruitment + four months of ramp-up (~EUR 27,000 of lost productivity) — about EUR 96,000 for those five months, with actual delivery in month seven due to ramp-up. Agency option: a team of two at EUR 600 day rate, starting in three weeks, ~105 days x 600 = EUR 63,000, delivery in month five. The agency delivers two months earlier for EUR 33,000 less on this project. The director picks the agency, then will assess in-house hiring only if the need becomes permanent above 85% utilisation. Verdict: agency for the project, in-house to consider for recurrence.
FAQ
What does an in-house developer really cost in 2026? Expect EUR 55,000-75,000 fully loaded per developer/year in Toronto, plus EUR 8,000-20,000 of recruitment and 3-6 months of ramp-up (EUR 20,000-40,000 of lost productivity) before full effectiveness.
Is the agency day rate an extra cost? Not necessarily: at EUR 450-750/day over 200 billed days, the agency costs EUR 90,000-150,000/year, comparable to two in-house devs, but with no recruitment, no ramp-up and paid only for days consumed.
What is the switching threshold to in-house? A permanent need with over 85% utilisation: at that level, in-house amortises recruitment and ramp-up in ~18 months and becomes cheaper while capitalising domain knowledge.
Who is faster? The agency, almost always at start: 2-3 weeks versus 3-6 months to hire and onboard. On an urgent project, that time-to-market gap is often decisive.
Is a hybrid relevant? Yes: one or two in-house devs steer the core and knowledge, the agency reinforces on peaks and rare skills. It is the most robust model for a long-term strategic need.
