TL;DR. For most TRY-only Turkish merchants under ~3M TRY annual volume, iyzico is the easiest start — broadest coverage, fastest approval, simplest 3D Secure. PayTR is the better choice when you've outgrown iyzico's pricing and want a slightly more aggressive negotiation; its dispute handling is also stronger. Stripe is the right pick when more than 20% of buyers are international, when you need recurring billing as a primary feature, or when you also sell digital subscriptions. Realistic decision: start with iyzico, add Stripe when international demand appears, switch to PayTR when negotiating fee tiers becomes worth your time.

This is a comparison of the three TRY-native processors that ship with most Turkish e-commerce platforms. We've tried to surface the real operational tradeoffs — not the marketing copy.

When each wins

iyzico wins for...

First-time merchants who want fast approval. Their onboarding flow is the most polished.
Diverse Turkish bank coverage. They support every meaningful Turkish issuer.
3D Secure simplicity. The integration "just works" with all major e-commerce platforms.
Small merchants who don't have leverage to negotiate fees. The published rate is the rate.

iyzico's downside: limited room to negotiate as you scale. At 5M+ TRY/year you'll often save money switching to PayTR.

PayTR wins for...

Mid-market merchants (3M–30M TRY/year) who can negotiate. They have explicit volume tiers and your account manager will quote them.
High-dispute categories like apparel and electronics. Their dispute resolution team is more responsive than iyzico's.
Merchants who also sell on Trendyol/Hepsiburada. PayTR has tighter integration with marketplace settlement flows for some sellers.
Sellers who need installments (taksit). Both processors support installments, but PayTR's installment campaign tooling is more flexible.

PayTR's downside: slightly slower onboarding and fewer plug-and-play integrations with smaller e-commerce platforms.

Stripe wins for...

International sellers. If more than 20% of your revenue is from EU/US/UK buyers, Stripe's exchange rate handling and fraud tools save more than the rate difference.
Subscription / SaaS / recurring billing. Stripe Billing is best-in-class. iyzico and PayTR can do recurring via add-ons; Stripe does it natively.
Stripe Connect (if you operate a marketplace yourself and need to split payments to multiple sellers).
API-first merchants with engineering capacity. Stripe's developer experience is better.

Stripe's downside in Turkey: slower onboarding, slightly higher base rate for Turkish-card transactions, and Shopify Payments is not available in Turkey so you can't use Shop Pay.

Approval requirements

All three processors require similar documents in Turkey:

Tax identification number (vergi numarası)
Trade registry gazette (Ticaret Sicil Gazetesi) for incorporated entities
Signature circular (imza sirküleri)
Bank account in the company name with IBAN
Certificate of activity (faaliyet belgesi)

Differences:

iyzico approves on documentation alone for most categories within 3–5 business days.
PayTR asks more questions for high-risk categories (gold, electronics, supplements). 5–10 business days.
Stripe runs through their Turkish onboarding partner, which adds a week. Some category restrictions are stricter (regulated goods, some financial services).

3D Secure and fraud

Mandatory in Turkey for online card payments. All three processors implement 3DS 2.0 by default. Differences:

iyzico: 3DS pass-through is the smoothest — fewest false declines on legitimate Turkish cards.
PayTR: comparable to iyzico; stronger fraud rules toolkit if you want to override defaults.
Stripe: best ML-driven fraud detection (Stripe Radar), but Turkish card-issuer behavior occasionally trips it. Expect to tune rules in the first month.

For high-fraud categories (gold, gift cards, mobile recharges), all three will require additional KYC and may impose volume caps.

Settlement timing

iyzico and PayTR: T+1 (next business day) is the standard. T+0 is available for select merchants on higher tiers.
Stripe: T+2 default in Turkey; T+1 available with established history.

In practice the cash-flow difference is one business day, which usually doesn't matter — except if you sell items where you ship before settlement clears, in which case T+1 is materially better than T+2.

Disputes and chargebacks

Turkish consumer-protection law gives buyers a 14-day no-questions-asked return on most online purchases. That's separate from card-network chargebacks (fraud, "didn't receive," etc.).

iyzico: average dispute response. Their portal is functional but documentation requirements feel heavy.
PayTR: stronger dispute team. Higher recovery rate on legitimate disputes (the merchant's side).
Stripe: best dispute UI; clear evidence-submission flow; Stripe Radar's fraud scoring helps preempt disputes.

If you're in a dispute-heavy category (apparel, electronics, beauty), this matters. If your dispute rate is below 0.5%, all three are comparable.

International support

If you take 5–10% international: iyzico/PayTR's "international card" surcharge handles it acceptably. If you take 20%+ international: Stripe's exchange rate, multi-currency settlement, and fraud tools start to outweigh the higher base rate.

Pricing example: 1,000,000 TRY annual volume

For an SMB merchant doing ~1M TRY/year, ~95% Turkish cards, average ticket 250 TRY (4,000 transactions/year):

	iyzico	PayTR	Stripe
Card fee (2.49% / 2.39% / 2.9%)	~24,900	~23,900	~29,000
Per-transaction (0.25 / 0.20 / 0.30)	~1,000	~800	~1,200
Total annual	~25,900	~24,700	~30,200

The difference between iyzico and PayTR is roughly 1,200 TRY/year — not enough to switch over, but enough to negotiate iyzico down to PayTR's rate if you bring volume.

The Stripe gap (~4,300 TRY/year) is the cost of better international handling and recurring billing — worth it if you use those features, otherwise not.

FAQ

Can I use multiple processors simultaneously? Yes. Many merchants use iyzico as primary and Stripe as secondary for international cards. The platform handles routing.

Which is best for installments (taksit)? All three support installments. PayTR has the most flexible campaign tooling for taksit promotions; iyzico is simpler; Stripe's installment support in Turkey is more limited.

What about iyzico's "Bedava" (free) plan? iyzico's standard rate is ~2.49% + 0.25 TRY regardless of volume; "free" plans referenced in marketing are usually annual fee waivers, not per-transaction fee waivers.

Can I switch processors mid-year? Yes. Switching is mostly a settings change in your e-commerce platform plus updating webhook URLs. The painful part is failing transactions during the transition window — schedule the switch for low-volume hours.

Does FaStart support all three? Yes. iyzico, PayTR, and Stripe ship pre-wired in FaStart. Switching processors is a UI toggle.

If you're choosing your first processor and want to test cleanly: start with iyzico on FaStart's Free plan, ship 100 orders, and re-evaluate. The fee difference between processors is a rounding error compared to the cost of choosing one before you understand your traffic mix.
