Adyen vs Sipay

Adyen is a global payments company founded in Amsterdam in 2006 by Pieter van der Does and Arnout Schuijff, and listed on Euronext Amsterdam since 2018. Adyen runs its own acquiring, processing and risk stack in one system, so a merchant gets one contract and one report for card payments, local payment methods and in-store terminals across many countries. Customers include Uber, Microsoft, eBay and OpenAI.

The platform covers online checkout through Drop-in and Components SDKs, point-of-sale terminals, Tap to Pay on phones, RevenueProtect fraud scoring, network tokenization, payouts, and Adyen for Platforms for marketplaces that onboard and pay sub-merchants. Pricing is published and usage-based: a fixed $0.13 processing fee per transaction plus a payment method fee, such as Interchange++ plus 0.60% for Visa and Mastercard. There are no setup or monthly fees, though a minimum invoice can apply depending on industry.

Adyen fits large retailers, travel and mobility companies, and marketplaces processing high volumes across several regions, where unified data and acquiring margins matter. It is a poor fit for small shops: onboarding is sales-led, integration needs developers, and support is tuned for enterprise accounts. Stripe is easier for startups and SaaS billing, PayPal brings consumer wallet reach, and Square suits small in-person sellers.

Adyen keeps growing: H1 2026 net revenue was about EUR 1.3 billion, up 19% year on year, and in July 2026 it completed the acquisitions of Talon.One (loyalty and promotions) and Orb (usage-based billing).

Sipay is a Turkish fintech company based in Istanbul and licensed by the Central Bank of the Republic of Turkey as an electronic money institution. It provides payment infrastructure for online and offline merchants and a digital wallet for consumers, positioning itself as a single provider for collecting payments, splitting funds and paying out.

For merchants, Sipay offers virtual POS for card acceptance, installment payments with Turkish card programs, payment links that can be shared over messaging apps, email or social media, recurring payments, and marketplace and sub-merchant payment flows that split funds between sellers. Plugins for popular e-commerce platforms speed up integration, and APIs serve custom checkouts. The consumer wallet supports money transfers, bill payments and shopping. Pricing is commission-based and negotiated per merchant, depending on volume, sector and settlement schedule.

Sipay fits Turkish e-commerce sites, marketplaces and service businesses that want one partner for online collection, installments and marketplace payouts. Merchants should compare commission rates, settlement times, installment options, support quality and fraud tools before choosing. iyzico and PayTR are the main local competitors, Param is another licensed alternative, and Stripe is not directly available to companies registered in Turkey.
