The three models in one frame
| Dimension | Staff augmentation | Outsourcing | Build-Operate-Transfer |
|---|---|---|---|
| End state | partner keeps engineers | partner keeps engineers | client absorbs engineers |
| Duration | 3 months+ | scope-bound | 18–36 months |
| Cost | $55–$95/hour | $65–$115 effective | 15–25% premium during operate |
| Transfer cost | none | none | one-time fee (~€10k–€25k/engineer) |
| Best fit | flexible capacity | bounded project | EU subsidiary build |
How BOT actually works
Phase 1, Build (3–6 months)
The partner recruits, vets, and onboards the team in-country. Client signs off on hires. Partner employs the engineers under its legal entity.
Phase 2, Operate (18–30 months)
Partner runs day-to-day employment, payroll, benefits, office. Engineers work full-time for the client under the partner's HR umbrella. Client pays operating fee.
Phase 3, Transfer (1–3 months)
Client either acquires the partner's local entity or rehires engineers under a new client-owned entity. Engineers consent to the transfer. Partner provides transition support.
When BOT wins
- Long-term EU subsidiary strategy (3+ year horizon)
- Need to absorb engineers as direct employees eventually
- Regulated industry requiring direct employment
- Want to test a geography before committing to subsidiary setup
When BOT loses
- Short-term needs (under 18 months), pay BOT premium without reaching transfer
- Flexible-capacity needs, staff augmentation is more elastic
- No appetite for EU entity ownership, outsourcing is cleaner
Cost over a 36-month horizon
For a 10-person team:
- Staff augmentation 36 mo: ~$3.5M
- Outsourcing 36 mo: ~$3.9M (capped scope)
- BOT 36 mo: ~$4.1M operate + ~€200k transfer = ~$4.3M total
BOT is more expensive nominally but ends with engineers as direct employees, a balance-sheet asset rather than ongoing operating expense.
