The checkout step is the last and most critical stage where the visitor turns into a customer. Lack of an installment option, errors in the 3D Secure step, or the foreign customer's inability to find the payment method they are accustomed to will result in the loss of orders that have reached the basket. The unavailability of Shopify Payments in Türkiye makes choosing the right payment infrastructure even more important.
