Six mistakes foreign investors make entering Türkiye — and how to avoid them

Every quarter we sit across the table from foreign decision-makers — directors of international operations, family-office principals, regional VPs — who are evaluating Türkiye for the first time. The names change. The companies change. The mistakes don’t.

This is the short list of the patterns we see most often, and the structural fix for each. None of this is theoretical. We’ve watched real investors lose 6–18 months — and 15–40% of project budget — to one or more of these.

1. Treating Türkiye like Eastern Europe

The most common opening assumption is that Türkiye fits the “Eastern European emerging market” mental model: do feasibility, hire a local lawyer, sign with a builder, get incentives. That model breaks here for two reasons.

First, the regulatory and incentive landscape is more dynamic. Investment region codes, OSB eligibility, YEKDEM tariff windows, customs duties on imported equipment — these change. A study run in Q1 may be partially obsolete by Q3.

Second, the local supply chain is genuinely competitive. A serious foreign investor who never asks local-versus-imported pricing on switchgear, cabling, structural steel, or HVAC equipment routinely overpays by 20–40%. The savings are real, but they require knowing who to call.

Fix: ground the entry plan in current data and a real local supplier benchmark, not a generic regional template. This is the core of our market entry consulting.

2. Hiring three firms that don’t talk to each other

The classic pattern: a Big 4 firm for strategy, a local law firm for company formation, and a general contractor for delivery. On paper this is fine. In practice, the three almost never talk. The Big 4 hands over a deck. The lawyer files what they’re asked to file. The contractor builds what they’re shown.

Nobody owns the gap between strategy and delivery. So when the construction permit turns out to require a different company structure than the one the lawyer set up, or when the EPC realizes the site selection didn’t account for medium-voltage grid distance, you find out about it in month 7. Schedule and cost slip together.

Fix: have one accountable counterparty across the workstreams. Either a sufficiently senior internal program manager who flies in monthly, or a single partner like Seza who signs on all of them — strategy, legal, delivery — under one contract. See our six services.

3. Choosing a partner from the wrong shortlist

Foreign investors often pick a Turkish partner from the obvious sources: people the Big 4 introduces, the largest holdings the embassy commercial counsellor knows, or the firms that have the slickest English website. These shortlists are rarely the right shortlist.

The actual best Turkish partners for a specific scope are often mid-cap firms that don’t do English-language marketing, or technical firms that have never been listed in a foreign-investor directory. They show up only if you have local network depth — and the willingness to do old-fashioned diligence: site visits, reference calls in Turkish, balance-sheet analysis, prior-year tax filings.

Fix: build the long list from operational sources, not curated directories. Then run real diligence — financial, legal, reputational. We do this under our partnership matching engagement.

4. Underestimating the permit and incentive timeline

Investors price feasibility studies at $50K–$200K. They price the construction phase at €5M–€50M. Then they treat the 4–9 months of permit, incentive, and authority interface in between as administrative overhead. It is not.

In a serious industrial or energy project, the incentive certificate, the OSB contract, the building license, and the grid-connection approval are sequenced operations with concrete eligibility windows. Miss a YEKDEM window because incentive paperwork was filed two weeks late and you reset the project economics for the next several years.

Fix: build the regulatory timeline as a first-class project track — not a pre-build blocker — and run it in parallel with site work, not after. Our legal & permit coordination is purpose-built for this.

5. Treating cost transparency as “trust the contractor”

In many markets, a foreign investor signs an EPC contract and assumes the EPC’s margins are roughly understood. In Türkiye, the gap between what an unsupervised EPC pays for materials and labor versus what they invoice the foreign client can be large — sometimes very large. Not because of fraud, but because there’s no easy way for the foreign client to verify.

The fix is unglamorous: insist on disclosed-margin sourcing, factory audits, line-item supplier quotes, and right-to-audit clauses. None of this requires distrust. It requires basic process, the kind of process that the better Turkish suppliers respect because it filters out tire-kickers.

Fix: build cost transparency into the contract structure on day one. Our materials & labor sourcing service formalizes this.

6. Going home after “handover”

The last mistake is the one that costs the most over a 5–10 year horizon. The investor delivers the factory, the hotel, the data center, declares victory, and rotates the senior team out. Local representation gets handed to the cheapest available administrative manager.

Then year-two regulatory changes don’t make it back to HQ in time. Supplier relationships quietly degrade. KVKK audits surface gaps that were never raised. The asset is technically running, but the operational margin slowly compresses, and HQ wonders why Türkiye keeps under-performing on its plan.

Fix: treat operational presence as a long-term cost line, not a temporary one. Even a part-time senior local representative who attends quarterly board meetings, monitors regulatory changes, and audits supplier performance is dramatically more valuable than the savings from cutting the role. See local representation.

The pattern

All six mistakes share a single shape: treating the Türkiye engagement as a sequence of transactions, each handed off to a different firm, rather than as a system that needs one accountable owner. Foreign investors who build that single line of accountability — internally or through a partner — consistently deliver on time and on budget. Foreign investors who don’t, consistently don’t.

That’s the gap Seza Partners was built to fill. If your Türkiye project is in the evaluation, partner-search, or delivery phase and any of these patterns sound familiar, the fastest test is a 30-minute call.
