Online Booking for Psychologists, Dietitians and Clinics in Turkey: A KVKK-Compliant Setup Guide
An online booking system for a psychologist, dietitian or small clinic should collect only a name, contact details and a preferred time, because health data is special-category data under Turkey's KVKK. This guide covers reminders that reveal nothing sensitive, privacy notice and explicit consent, cross-border data transfer after Law No. 7499, payments, Turkey's 2025 health advertising regulation and booking chatbots. It is general information, not legal advice.

Hotel Direct Booking System: How Boutique Hotels Reduce OTA Commission With Their Own Booking Site
A direct booking system lets a hotel take reservations on its own site, so the commission an OTA such as Booking.com would charge stays with the hotel. It does not replace the platforms; it shifts part of the mix. This guide covers the real cost of OTA commission, the features a booking engine needs, channel managers, Google's free booking links, legal duties in Turkey and a break-even formula.

Choosing an E-Commerce Payment Gateway in Turkey (2026): Bank Virtual POS vs iyzico, PayTR and Stripe
An online store in Turkey takes card payments through a bank's virtual POS or a payment institution licensed by the Central Bank (TCMB). Total cost decides between them, not the headline rate: settlement time, instalments, foreign cards, refunds and integration quality. A selection checklist.

Website Maintenance Cost in 2026: What a Live Site Really Costs Each Month

What Is the WhatsApp Business API and What Does It Cost in Turkey? The 2026 Guide
The WhatsApp Business app is for a person on a phone, the API is for software.

Here is when the free app is enough, what the October 2026 pricing change means, the İYS consent rules for bulk messages, and how a sane integration is built.

How Do I Publish My App on the App Store and Google Play in 2026? Fees, Review Times and Rejection Traps
Apple charges 99 USD a year, Google charges 25 USD once, and Apple says 90% of submissions are reviewed in under 24 hours. The real delay sits elsewhere: a new personal Google Play account must run a closed test with 12 testers for 14 days, and an organization account needs a D-U-N-S number first. Here is the full 2026 release sequence, the rules that changed this year, and the reasons behind more than two million App Store rejections.

Is a Cookie Banner Mandatory in Turkey? The 2026 KVKK Checklist for Websites
Yes for almost every business site: under KVKK, analytics, advertising and social media cookies need explicit consent before they are set. But the banner is one of seven things a compliant website must get right. Privacy notice versus explicit consent, contact form data, VERBİS thresholds after the October 2025 change, cross-border transfers to hosting and analytics providers, İYS for commercial messages, and the 2026 fine amounts, each with its published source and date.

Who Owns the Source Code When You Hire a Software Company in Turkey? What the Contract Must Say (2026)
Unless a written contract lists each right, the developer keeps the economic rights to the code you paid for. Under Law No. 5846 (FSEK) software is a protected work, Article 52 demands a written transfer that names every right, and a 2020 Court of Cassation General Assembly ruling shows a silent contract gives you only use within the agreed scope. The articles, the clauses to write in, and the red flags in vendor proposals.

Marketplace Commissions vs Your Own Store: The Real 2026 Math for Turkish Sellers
Sellers quote the commission rate. The commission is only the first of five deductions. Trendyol takes 7% on a phone and 23.39% on footwear, then adds a per-shipment platform fee, shipping, ad spend, forced campaign discounts and return operations. Your own store's payment cost is around 1-2%. Here is the layer-by-layer breakdown and the break-even formula that says when to build.
