Corporate Cards in Turkey: A 2026 Buyer's Guide

Turkey has more corporate card options than most European markets, and yet most finance teams in Istanbul still run on a single-bank arrangement they inherited from the founder's personal banking relationship. That made sense in 2018. It costs real money in 2026.

The Turkish corporate card landscape

Seven banks dominate Turkish corporate cards: Akbank, Garanti BBVA, İş Bankası, Yapı Kredi, QNB Finansbank, Ziraat Bankası, and Halkbank. Each offers a fundamentally similar product: a physical Visa or Mastercard tied to a TL account, with optional FX cards in USD and EUR. The differences are in controls, software, and integration depth, not in the card itself.

On top of the banks, you have eleven local payment service providers (iyzico, PayTR, Craftgate, Sipay, Hepsipay, Param, Moka, Papara, Paynet, JetPay, United Payment) and the global card issuers (Stripe Issuing, Adyen Issuing) that operate in Turkey through partnerships.

What to actually compare

Forget the marketing pages. Compare on these four dimensions:

1. Virtual card issuance speed. Can your team issue a single-use card in under a minute, or does it require a bank visit? Banks: typically slow. Modern platforms: instant.
2. Per-card controls. Can you set a category limit (MCC block) on a single card, or only at the account level? Most Turkish banks: account-level only. Modern platforms: per-card.
3. FX handling. A TL corporate card paying for a USD SaaS subscription should not lose 2-3% to your bank's FX markup every month. Multi-currency platforms hold balances in USD and EUR natively, eliminating the round trip.
4. Accounting integration. Does the card data flow into your accounting system (Logo, Mikro, Netsis, or a SaaS like Paraşüt) automatically, or does someone in finance hand-code transactions every week?

The BDDK angle

BDDK (Turkey's banking regulator) treats corporate cards similarly to consumer cards for capital adequacy, but Article 9 of the relevant regulation requires Turkish-domiciled cardholders to use Turkish-licensed issuers for primary spend. In practice this means: if your team is in Turkey and your entity is Turkish, you cannot run primary spend through a foreign issuer like Brex or Ramp. You can use them as a secondary card for USD spending, but Turkish lira spend needs a Turkish-licensed solution.

This is the single most-misunderstood rule we see. Founders try to run a Turkish team on a Mercury card and discover at year-end that the auditor will not accept it as corporate spend.

When a bank card is enough

If your team is under 15 people, all in Turkey, all spending in TL, and you do not pay vendors abroad, a vanilla İş Bankası or Akbank corporate card with their basic online portal is fine. The controls are weak, but the volume is low enough that finance can clean it up at month-end. Do not over-engineer at this scale.

When you need more

You need more than a bank card when any of these become true:

• More than 20 people using cards, especially across multiple locations
• Recurring international vendor payments (AWS, Google Workspace, GitHub, OpenAI)
• Vendor or per-project spend tracking you cannot do in a spreadsheet
• A team that travels (the bank's expense report tool is consistently the worst part of every Turkish bank's stack)
• Any AI or automated buying use case where you need scoped mandates

At that point you want a card platform on top of a bank, not instead of one. The card platform handles issuance, controls, and software; the bank handles the actual rails and the BDDK paperwork.

Specific bank notes

Akbank. Best software of the traditional banks. Akbank Direkt portal is genuinely usable. FX markup is competitive. Their corporate card API is the most mature.

Garanti BBVA. Strong physical card product. The integration with BBVA group means you get reasonable cross-border tooling. Limited API surface for software integrations.

İş Bankası. Largest bank, widest acceptance. Software is functional, not best-in-class. Strong for traditional companies with a long banking relationship.

Yapı Kredi. Good for international travel. Higher fees on the premium tiers.

QNB Finansbank. Strong on FX cards. Good for teams with USD revenue.

Ziraat, Halkbank. State banks. Cheapest fees, weakest software, slowest support. Use only if you have a specific reason to bank with a state institution.

What we recommend in 2026

For most growing Turkish teams: keep your bank relationship for treasury and lending, run cards through a modern platform that integrates with your bank, and add a multi-currency layer for international SaaS spend. The savings on FX markup and the time saved at month-end pay for the platform within the first quarter.
