Why Istanbul businesses are investing in mobile commerce apps
Istanbul is a largest city in turkey, with a population of roughly 16 million, and one of the markets in Türkiye where we build mobile commerce apps.
Key sectors include E-commerce, gaming studios, crypto exchanges and banks, with business districts such as Levent, Maslak, the Istanbul Financial Center and Kadıköy.
Logistics are supported by Istanbul Airport and Sabiha Gökçen 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 Istanbul are moving from phone, WhatsApp and spreadsheet orders to a proper shopping app — one place where products, prices, payments, orders and customers are managed together.
Local details we build into every Istanbul project
Conversion in Istanbul depends on small local signals — the right currency, the right words and the right payment and courier names.
Currency and pricing
Everything a Istanbul shopper sees — price, tax, delivery fee, refund — is in TRY, written the local way.
Language and content
Storefront copy, product pages and emails can run in Turkish, with local date and number formats.
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. Click-to-call and WhatsApp buttons use the +36 calling code so customers reach you without dialling errors.
Talent and partners nearby
With Boğaziçi, Istanbul Technical University and Koç University close by, finding people to manage catalogues, content and support after launch is realistic in Istanbul.
Custom-built for how you sell in Istanbul
If you run a business in Istanbul and want to sell online, we build an e-commerce platform and mobile application to your exact requirements, from the first product page to the last delivery update.
In Istanbul we typically work with retail brands, grocery and pharmacy chains, restaurants and cloud kitchens and distributors with dealer networks, 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.
Features of your shopping app in Istanbul
These are the building blocks of a shopping app. We scope them with you, so you pay for what your Istanbul operation needs.
Customer shopping app
Browse, search, wish-lists, cart, wallet and UPI or card checkout, order tracking and push offers. Revenue reports by product, repeat buyer and delivery area of Istanbul guide stock and marketing decisions.
Dealer and B2B app
Account pricing, quick re-order, statements, schemes and barcode scanning for trade buyers. Storefront language, imagery and navigation are set up for Istanbul shoppers and available in Turkish.
Delivery partner app
Assigned orders, route navigation, proof of delivery, COD collection and status updates. Catalogues come in from spreadsheets, ERP exports or supplier feeds, so your Istanbul team keeps its current way of working.
Store and admin app
Order alerts, stock updates, price changes and sales snapshots for owners and managers. Payment steps are built around credit cards with instalments (taksit), Troy cards and iyzico, the options shoppers here already trust.
Engagement
Segmented push notifications, deep links, in-app banners, loyalty and referral programmes. Shipping rules can use PTT Kargo, Yurtiçi Kargo and Aras Kargo as well as your own delivery staff in Istanbul.
Performance and offline
Fast native-feel UI, image caching, offline cart and graceful handling of poor networks. Inventory can sit in Istanbul, in a partner warehouse or across Türkiye, with click-and-collect where customers want it.
Industries in Istanbul we work with
Popular online categories in Türkiye include fashion, electronics, home and textiles, groceries, beauty and furniture. Local demand in Istanbul is shaped by E-commerce, gaming studios, crypto exchanges and banks, so we often design catalogues and B2B ordering around those sectors. In Istanbul, we most often build mobile commerce apps for:
Retail brands
Retail brands get customer shopping app plus delivery partner app workflows tailored to their operations.
Grocery and pharmacy chains
We map how grocery and pharmacy chains sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
Restaurants and cloud kitchens
For restaurants and cloud kitchens, we usually start with store and admin app, then add Firebase and push messaging once orders are flowing.
Distributors with dealer networks
Catalogue, pricing and fulfilment rules designed for distributors with dealer networks in Istanbul, connected to the systems you already use.
D2C start-ups
D2C start-ups get engagement plus customer shopping app workflows tailored to their operations.
Marketplace operators
We map how marketplace operators sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.
How Istanbul customers pay online
A shopping app for Istanbul must support the way people here actually pay: credit cards with instalments (taksit), Troy cards, iyzico, 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).
Business buyers around Levent often want invoices or bank transfer, while consumers lean on credit cards with instalments (taksit). We support both flows.
- Iyzico
- Credit cards with instalments (taksit)
- Bank transfer (FAST)
- Cash on delivery
- PayTR
- Troy cards
Shipping, couriers and local delivery in Istanbul
Your shopping app 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 Istanbul.
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.
Connectivity in the area — Istanbul Airport and Sabiha Gökçen Airport — makes regional and national dispatch from Istanbul practical.
Owning your channel in Türkiye
Many Istanbul 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.
NNT Mart gives you a channel you own: your domain, your customer list, your pricing and your brand. Where it helps, we connect product feeds and orders from marketplaces so stock stays in sync and your team works from one dashboard.
Selling online legally in Türkiye
For Istanbul sellers, tax first: Turkish VAT (KDV) is 20% standard with 10% and 1% reduced rates; e-Arşiv and e-Fatura invoicing are required above set thresholds.
Two frameworks shape the build: the Personal Data Protection Law No. 6698 (KVKK), including VERBIS registration for many data controllers, and 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 in Türkiye.
Add a mobile app for Istanbul customers
In Istanbul, shoppers browse on phones first. Every app is published under your own Google Play and Apple developer accounts, with crash reporting, analytics and release management included.
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.
Push notifications can be timed to UTC+3 so offers reach Istanbul customers when they are awake, and the interface can run in Turkish.
- Social login
- Barcode and QR scanning
- Maps and location services
- Analytics and crash reporting
- Commerce APIs and headless backends
- Payment SDKs and wallets
- Firebase and push messaging
- Customer support chat
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 Istanbul
We launch the journeys that create value first, then add depth. A typical roadmap for a shopping app in Istanbul:
| Phase | What goes live |
|---|---|
| MVP app | Core shopping, checkout, order tracking and push notifications. Configured for TRY, credit cards with instalments (taksit) and PTT Kargo from the start. |
| Engage | Loyalty, referrals, personalised offers and deep links. |
| Extend | Dealer, delivery and admin apps on the same backend. Reviewed against how Istanbul customers actually buy. |
Success is measured on app installs and active users, app conversion rate, push-notification click rate, crash-free sessions, store rating and share of revenue from app — tracked on a dashboard you can see from launch day.
Support hours and communication for Istanbul
Istanbul 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 shopping app.
Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; Istanbul clients are served remotely with on-site workshops when the project needs them.
