  • VAT-ready invoicing and controls designed around the Personal Data Protection Law No. 6698 (KVKK).

Why a custom e-commerce platform makes sense for Türkiye

Türkiye is a market of about 85 million people where custom e-commerce platforms are growing fast, with Ankara as its capital.

Türkiye has a large, digitally fluent population and a culture of card instalments that strongly drives online sales. E-invoicing and ETBIS registration need to be part of the platform.

For a business in Türkiye, the opportunity is to own the customer relationship: your own custom e-commerce platform keeps your margin, your data and your brand, while marketplaces and social channels become additional sales routes instead of the only one.

Localised for Türkiye, not translated into it

Conversion in Türkiye depends on small local signals — the right currency, the right words and the right payment and courier names.

Currency and pricing

Prices, taxes, shipping and refunds are shown in Turkish lira (TRY), formatted the way Türkiye customers read them.

Language and content

Content can be produced in Turkish, so a Türkiye customer reads the store in the language they use at home.

Local trust signals

Trust is local: familiar names such as credit cards with instalments (taksit) and Troy cards and PTT Kargo sit next to the buy button.

Domain, phone and contact

A .tr domain (or your own) builds local trust and search relevance. Contact buttons are pre-set with +36, so a customer in Türkiye taps once to call or message.

Designed to your requirements, not a template

Your custom e-commerce platform is planned, designed and coded for your business model — not adapted from someone else's — and it can ship with a customer or staff mobile app on day one.

In Türkiye we typically work with enterprises with complex catalogues, multi-brand groups, businesses outgrowing SaaS platforms and companies migrating legacy stores, and with sellers in categories such as fashion, electronics, home and textiles and groceries that have strong online demand in Türkiye.

Before any commitment you get a free requirements meeting, a demo built on your use case and a proposal priced to your budget.

Core modules we build for Türkiye clients

Nothing here is fixed: modules are switched on, reshaped or built from scratch around how your Türkiye business sells.

Custom workflows

Product configurators, made-to-order flows, approvals, contracts and industry-specific rules. Revenue reports by product, repeat buyer and delivery area of Türkiye guide stock and marketing decisions.

Headless architecture

API-first commerce with a fast front end, so web, app, kiosk and marketplace channels share one backend. Storefront language, imagery and navigation are set up for Türkiye shoppers and available in Turkish.

Multi-entity operations

Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Bulk import and sync tools mean the Türkiye team never re-keys stock, prices or descriptions by hand.

Deep integrations

ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Customers in Türkiye can pay with credit cards with instalments (taksit), Troy cards and iyzico, with receipts and refunds handled in the same admin.

Migration

Move from older platforms with product, customer and order history, SEO-safe redirects and parallel runs. Shipping rules can use PTT Kargo, Yurtiçi Kargo and Aras Kargo as well as your own delivery staff in Türkiye.

Performance and security

Caching, CDN, load testing, security hardening, audit logs and cloud infrastructure as code. Multiple stock points in Türkiye are supported, so a Türkiye order ships from the nearest one.

Checkout and payment methods for Türkiye

Checkout is where most online sales are won or lost. In Türkiye, customers expect to pay with credit cards with instalments (taksit), Troy cards and iyzico, and many also look for PayTR, bank transfer (FAST) and cash on delivery.

We integrate suitable gateways and providers for your business category and merchant eligibility, handle payment status, failed-payment retries and refunds, and keep sensitive card data with the provider rather than on your servers. All amounts are shown in Turkish lira (TRY).

  • Troy cards
  • Cash on delivery
  • PayTR
  • Iyzico
  • Bank transfer (FAST)
  • Credit cards with instalments (taksit)

Fulfilment options for Türkiye orders

Your custom e-commerce platform can book shipments and share tracking with PTT Kargo, Yurtiçi Kargo, Aras Kargo, MNG Kargo, Sürat Kargo and Trendyol Express, or route orders to your own riders and stores.

Delivery rules can price by distance, weight, postcode or zone, offer same-day slots in dense areas, and switch on pickup points or click-and-collect where customers prefer them.

Compliance built into your custom e-commerce platform

On tax: Turkish VAT (KDV) is 20% standard with 10% and 1% reduced rates; e-Arşiv and e-Fatura invoicing are required above set thresholds.

Customer data is handled with the Personal Data Protection Law No. 6698 (KVKK), including VERBIS registration for many data controllers in mind, and the storefront follows Consumer Protection Law No. 6502 and the E-Commerce Law No. 6563, including ETBIS registration.

Our job is the engineering: price display with tax, invoice numbering, cookie and marketing consent, return and terms pages, role-based access and logs. Legal and tax conclusions stay with your own adviser.

Türkiye sellers: marketplace plus your own store

Many Türkiye sellers already list on Trendyol, Hepsiburada, Amazon.com.tr, n11, Çiçeksepeti and Getir. Those channels bring traffic, but they also take commission, control the customer relationship and change rules without notice.

With your own custom e-commerce platform you keep the customer data, set the offers and the packaging, and still push stock to marketplaces from a single admin.

Who we build for in Türkiye

Popular online categories in Türkiye include fashion, electronics, home and textiles, groceries, beauty and furniture. In Türkiye, we most often build custom e-commerce platforms for:

Enterprises with complex catalogues

Catalogue, pricing and fulfilment rules designed for enterprises with complex catalogues in Türkiye, connected to the systems you already use.

Multi-brand groups

Multi-brand groups get headless architecture plus deep integrations workflows tailored to their operations.

Businesses outgrowing SaaS platforms

We map how businesses outgrowing SaaS platforms sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

Companies migrating legacy stores

For companies migrating legacy stores, we usually start with migration, then add POS and store systems once orders are flowing.

Regulated sectors

Catalogue, pricing and fulfilment rules designed for regulated sectors in Türkiye, connected to the systems you already use.

High-traffic retailers

High-traffic retailers get performance and security plus headless architecture workflows tailored to their operations.

Add a mobile app for Türkiye customers

Phones carry most traffic in Türkiye. Because the platform is API-first, customer, staff and partner mobile apps can be added at any point without rebuilding the backend.

Apps are published under your own developer accounts and share the same backend as your custom e-commerce platform, so offers, stock and orders are always consistent between web and mobile.

Order alerts, offers and abandoned-cart reminders go out on Türkiye time (UTC+3), in Turkish if you want.

  • PIM and DAM
  • WMS and 3PL systems
  • Cloud platforms (AWS, Azure, GCP)
  • Identity and SSO
  • BI and data warehouses
  • SAP, Oracle, Microsoft Dynamics and Odoo ERPs
  • Search engines (Elasticsearch, Algolia)
  • POS and store systems

Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.

Launch roadmap and success metrics

We launch the journeys that create value first, then add depth. A typical roadmap for a custom e-commerce platform in Türkiye:

PhaseWhat goes live
FoundationArchitecture, core commerce, priority integrations and migration. Configured for TRY, credit cards with instalments (taksit) and PTT Kargo from the start.
DifferentiateCustom workflows, configurators and automation.
OptimisePerformance, new channels, apps and continuous enhancement. Reviewed against how Türkiye customers actually buy.

Success is measured on page load and API response times, uptime, order-sync accuracy, manual-work hours saved, release frequency and total cost of ownership — tracked on a dashboard you can see from launch day.

Time zones, language and support

Türkiye runs on UTC+3, which is 2h 30m behind India (IST). With three 8-hour shifts we are available 24×7, so meetings, demos and urgent fixes happen in your working hours.

Project communication is in English; storefront content can be produced in Turkish. You get a named lead, direct engineer access and an NDA if you ask.

Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; clients in Türkiye are served remotely with on-site workshops when the project needs them.

Pay only for work you have accepted

Milestones are customised to your requirements — six or more is typical, and delivery time is agreed around your scope. Every payment after the advance is released only after you have seen the working result and given written sign-off. Here is an example plan for a custom e-commerce platform:

Protected after launch — warranty and annual support for your custom e-commerce platform

Every project includes a free 90-day defect warranty. After that, the same team that built your custom e-commerce platform keeps it secure, updated and running on a fixed annual fee agreed up front — no open-ended hourly billing and no surprise invoices.

No lock-in: the platform is yours

For every custom e-commerce platform, upon full and final payment the complete source code and intellectual property are transferred to you — so you can host, maintain and enhance the system with any developer.
