The case for a custom e-commerce platform in Gaziantep

Gaziantep is a metropolitan municipality in turkey, with a population of roughly 1.7 million, and one of the markets in Türkiye where we build custom e-commerce platforms.

Businesses here work in textiles, food manufacturing and trade; many are based around the organised industrial zones.

Logistics are supported by Gaziantep Airport, which matters when you promise customers fast delivery.

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.

That is why more companies in Gaziantep are moving from phone, WhatsApp and spreadsheet orders to a proper custom e-commerce platform — one place where products, prices, payments, orders and customers are managed together.

Localised for Gaziantep, not translated into it

A store that works in Gaziantep respects local habits as well as local law. These are the details we configure first.

Currency and pricing

The store speaks Turkish lira: TRY amounts from product page to invoice, so Gaziantep buyers never convert in their heads.

Language and content

Storefront copy, product pages and emails can run in Turkish, with local date and number formats.

Local trust signals

We add the payment logos, courier names and policy pages shoppers in Gaziantep recognise: credit cards with instalments (taksit) and Troy cards and delivery through PTT Kargo.

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 Gaziantep taps once to call or message.

Talent and partners nearby

With Gaziantep University close by, finding people to manage catalogues, content and support after launch is realistic in Gaziantep.

Designed to your requirements, not a template

We do not hand Gaziantep businesses a ready-made theme: we study how you sell, then build the online platform and Android/iOS app your customers and staff actually need.

Typical clients include multi-brand groups, businesses outgrowing SaaS platforms, companies migrating legacy stores and regulated sectors. Categories that sell especially well online in Türkiye — fashion, electronics, home and textiles and groceries — get catalogue structures and filters designed for them.

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 Gaziantep clients

Each module below is configured — or custom-developed — to your requirements. You choose what launches first and what follows in later phases.

Custom workflows

Product configurators, made-to-order flows, approvals, contracts and industry-specific rules. Dashboards break sales down by product, customer and neighbourhood of Gaziantep, so you see what to promote.

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 Gaziantep shoppers and available in Turkish.

Multi-entity operations

Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Catalogues come in from spreadsheets, ERP exports or supplier feeds, so your Gaziantep team keeps its current way of working.

Deep integrations

ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Customers in Gaziantep 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. Couriers such as PTT Kargo, Yurtiçi Kargo and Aras Kargo plug in alongside your own fleet for Gaziantep orders.

Performance and security

Caching, CDN, load testing, security hardening, audit logs and cloud infrastructure as code. Stock can be held in Gaziantep or anywhere in Türkiye, with pickup and local-delivery options where they make sense.

Checkout and payment methods for Gaziantep

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).

Zone-based payment rules let you offer different options for the organised industrial zones than for outer parts of Gaziantep.

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

Shipping, couriers and local delivery in Gaziantep

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 across Gaziantep.

We set up shipping zones, cut-off times, free-shipping thresholds, cash-collection rules and returns so the promise on the product page matches what your team can deliver.

Connectivity in the area — Gaziantep Airport — makes regional and national dispatch from Gaziantep practical.

Tax, invoicing and compliance in Türkiye

Tax basics: 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.

We build the technical controls — tax-inclusive pricing, compliant invoices, consent banners, terms and return pages, data-access roles and audit logs. We are not a law firm, so final legal and tax positions should be confirmed with your own adviser in Türkiye.

Owning your channel in Türkiye

Many Gaziantep 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 Gaziantep

Popular online categories in Türkiye include fashion, electronics, home and textiles, groceries, beauty and furniture. Local demand in Gaziantep is shaped by textiles, food manufacturing and trade, so we often design catalogues and B2B ordering around those sectors. In Gaziantep, 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 Gaziantep, 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 Gaziantep, 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.

Mobile commerce in Gaziantep

In Gaziantep, shoppers browse on phones first. Because the platform is API-first, customer, staff and partner mobile apps can be added at any point without rebuilding the backend.

One backend serves the website and the apps, and the apps ship under your own Google Play and App Store accounts — so what you change once appears everywhere.

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

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

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

A phased launch plan for Gaziantep

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

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 Gaziantep 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

Gaziantep 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.

We work in English and can deliver storefront content in Turkish. NDAs are signed on request, and you get a named project lead plus direct access to the engineers building your custom e-commerce platform.

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