Short answer: Build in-house when the software is your product and you need long-term institutional knowledge. Choose nearshore when you need real-time collaboration on domain-heavy work but cannot justify permanent headcount. Choose offshore when the work is well-specified, self-contained and cost is the dominant constraint. Most European companies end up with a hybrid: a small in-house core owning architecture and roadmap, with an external team handling delivery volume.
Defining the three models
| Model | What it means | Typical overlap with EU | Ramp-up |
|---|---|---|---|
| In-house | Permanent employees on your payroll | Full | 3 to 6 months per hire |
| Nearshore | External team within a few time zones | 6 to 8 hours | 2 to 4 weeks |
| Offshore | External team 5 or more time zones away | 2 to 4 hours | 2 to 4 weeks |
Turkey sits in the nearshore band for European and UK buyers at UTC+3, with no daylight saving change.
The true cost comparison nobody runs
The most common mistake is comparing a contractor's day rate against an employee's gross salary. These are not comparable numbers. A fair comparison includes everything an employer actually pays.
In-house cost stack
- Gross salary
- Employer social contributions and taxes
- Recruitment fee, often 15 to 25 percent of first-year salary
- Equipment, software licences, desk or remote allowance
- Management overhead
- Training and ramp-up time before productivity
- Idle capacity when the roadmap is thin
- Replacement cost when someone leaves
External team cost stack
- Day or monthly rate
- Onboarding time, usually billable
- Your own management time for coordination
- Knowledge transfer risk at the end of the engagement
The pattern most companies find: in-house is cheapest per unit of output only when utilisation stays high and tenure exceeds roughly two years. Below that threshold the recruitment and ramp-up cost never amortises.

When in-house is the right answer
Build in-house when three conditions hold at once. First, the software is the product: if your competitive advantage lives in the code, that knowledge should not be rented. Second, the workload is continuous, because a permanent team needs a permanent backlog. Third, you can actually hire: in much of Western Europe senior engineers take three to six months to recruit and command salaries that make small teams unviable.
If any of the three fails, an external model is usually better, at least until it does hold.
When nearshore is the right answer
Nearshore fits when the work is domain-heavy and requires frequent conversation rather than clean handoffs. Enterprise systems are the classic case: an ERP or CRM project depends on understanding how a specific business actually runs, and that understanding is transferred in dozens of short conversations, not in a specification document.
Four signals that point to nearshore:
- Requirements will evolve as you learn, which is true of most internal tooling
- Subject-matter experts on your side are busy and can only give short slices of time
- You need same-day answers, not next-day
- You want the option to convert to a longer engagement or in-house later
When offshore is the right answer
Offshore fits well-bounded work: a defined migration, a mobile app against a finished design system, a QA automation suite, or maintenance of a stable product. The common factor is that the specification can be written once and does not require continuous negotiation.
Offshore stops working when the specification is a moving target. Every hour of time-zone gap multiplies the cost of a misunderstanding, because the correction cycle takes a full day instead of ten minutes.
The hybrid model most companies land on
The arrangement that works for a large share of mid-sized European companies has three parts: one or two senior people in-house owning architecture, code review and the roadmap; an external team building against that direction; and a rule that the in-house core must be able to read and review everything the external team produces.
This preserves institutional knowledge while giving you elastic capacity. It also fails gracefully, because if the vendor relationship ends you still have people who understand the system.
Risks and how to control them
| Risk | Which model | Control |
|---|---|---|
| Key-person dependency | In-house | Documentation standard, pair review |
| Knowledge leaving at contract end | Nearshore and offshore | Written handover, code review by your side |
| Time-zone correction cycles | Offshore | Written specs, async-first tooling |
| Vendor quality variance | Both external | Paid pilot before full commitment |
| Idle capacity | In-house | Hire behind demand, not ahead |
| IP ambiguity | Both external | Explicit assignment clause and source delivery |
The single most effective control across all three: run a small paid pilot on one contained deliverable over four to six weeks before committing to a long engagement. You learn more from one shipped feature than from five sales calls.
Frequently asked questions
Is nearshore development cheaper than hiring in-house?
Usually yes over short and medium horizons, once recruitment fees, employer contributions, equipment, management overhead and ramp-up time are counted. In-house tends to win only when utilisation stays high and tenure exceeds roughly two years. Run the comparison over three years, not one.
What is the difference between nearshore and offshore?
The practical difference is working overlap, not distance. Nearshore means enough shared hours for same-day conversation, typically within two to three time zones. Offshore means the correction cycle takes a day, so the work must be specified more tightly upfront.
Can we start nearshore and move in-house later?
Yes, and it is a reasonable strategy. Make it viable from day one by contracting for source code ownership, requiring documentation as a deliverable, and having at least one person on your side review the code. Without those three the transition is expensive.
How do we test a vendor before committing?
Run a paid pilot on one contained deliverable over four to six weeks with a defined acceptance criterion. Judge them on how they handle the ambiguity you deliberately left in the brief, not on whether they hit the deadline.
Which model is best for ERP or CRM projects?
Nearshore in most cases. These systems depend on understanding how a specific business operates, which requires frequent short conversations with your own staff rather than a one-time specification handoff.
