The case for a shopping app in Košice
Košice is a commercial centre in Slovakia where around 222,000 people live and shop, and one of the places where we build mobile commerce apps for local businesses.
Key sectors include steel, IT, automotive suppliers and shared services, with business districts such as the city centre, Košice-Šaca and Hlavná ulica.
Logistics are supported by Košice International Airport and the D1 corridor, which matters when you promise customers fast delivery.
Slovakia has SMEs make up 99% of all businesses in the European Union (European Commission). Slovakia is a car-manufacturing economy with a strong e-commerce culture shared with Czechia, and parcel-point delivery through Packeta is the norm. Bank-button payments dominate checkouts.
That is why more companies in Košice 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.
Localised for Košice, not translated into it
Conversion in Košice 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 euro (EUR), formatted the way Košice customers read them.
Language and content
We localise pages, emails and notifications into Slovak, English and Hungarian where your audience needs it.
Local trust signals
Badges for Visa and Mastercard and Slovak bank buttons (Tatra banka, SLSP, VÚB), Slovenská pošta delivery and clear return terms reassure first-time buyers in Košice.
Domain, phone and contact
Using .sk where it suits you signals a local business to shoppers and search engines. Contact buttons are pre-set with +421, so a customer in Košice taps once to call or message.
Talent and partners nearby
With Technical University of Košice and P. J. Šafárik University close by, finding people to manage catalogues, content and support after launch is realistic in Košice.
Custom-built for how you sell in Košice
Whatever your business sells in Košice, N&T Software designs and develops the shopping app and the matching mobile app exactly to your requirements — your catalogue, your prices, your payment and delivery rules.
Typical clients include grocery and pharmacy chains, restaurants and cloud kitchens, distributors with dealer networks and D2C start-ups. Categories that sell especially well online in Slovakia — electronics, fashion, sports and home and DIY — 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 Košice clients
Each module below is configured — or custom-developed — to your requirements. You choose what launches first and what follows in later phases.
Customer shopping app
Browse, search, wish-lists, cart, wallet and UPI or card checkout, order tracking and push offers. Multiple stock points in Slovakia are supported, so a Košice order ships from the nearest one.
Dealer and B2B app
Account pricing, quick re-order, statements, schemes and barcode scanning for trade buyers. Reports show which products, customers and areas of Košice drive revenue.
Delivery partner app
Assigned orders, route navigation, proof of delivery, COD collection and status updates. Content and design can follow how customers in Košice search and buy, including Slovak and English where you need it.
Store and admin app
Order alerts, stock updates, price changes and sales snapshots for owners and managers. Product data imports from your existing sheets or ERP, so Košice teams do not re-type thousands of items.
Engagement
Segmented push notifications, deep links, in-app banners, loyalty and referral programmes. Customers in Košice can pay with Visa and Mastercard, Slovak bank buttons (Tatra banka, SLSP, VÚB) and PayPal, with receipts and refunds handled in the same admin.
Performance and offline
Fast native-feel UI, image caching, offline cart and graceful handling of poor networks. Delivery can be booked through Slovenská pošta, Packeta (Zásielkovňa) and GLS Slovakia or dispatched by your own riders around Košice.
Getting paid online in Košice
A store that serves Košice should let customers pay the way they do offline: Visa and Mastercard, Slovak bank buttons (Tatra banka, SLSP, VÚB), PayPal and Apple Pay and Google Pay.
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 euro (EUR).
Business buyers around the city centre often want invoices or bank transfer, while consumers lean on Visa and Mastercard. We support both flows.
- GoPay
- Twisto
- Visa and Mastercard
- Apple Pay and Google Pay
- PayPal
- Slovak bank buttons (Tatra banka, SLSP, VÚB)
Delivery and fulfilment from Košice
Your shopping app can book shipments and share tracking with Slovenská pošta, Packeta (Zásielkovňa), GLS Slovakia, DPD Slovakia, SPS and Packeta Z-BOX lockers, or route orders to your own riders and stores across Košice.
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 — Košice International Airport and the D1 corridor — makes regional and national dispatch from Košice practical.
Compliance built into your shopping app
Tax basics: Slovakia charges 23% VAT from 2025 (19% in 2024) with 10% and 5% reduced rates, and uses the EU One-Stop Shop.
Two frameworks shape the build: the GDPR and Act No. 18/2018 on Personal Data Protection, enforced by the Office for Personal Data Protection, and the Consumer Protection Act and the Act on Distance Contracts, with 14-day withdrawal rights.
Controls we implement include compliant invoices, consent capture, policy pages, restricted staff access and audit trails. Please confirm the final legal and tax position with a local adviser in Košice.
Marketplaces vs. your own shopping app in Košice
Heureka.sk, Bazos.sk and Alza.sk are where many shoppers in Košice start, which is why sellers list there. The trade-off is commission, limited branding and rules the platform can change overnight.
With your own shopping app you keep the customer data, set the offers and the packaging, and still push stock to marketplaces from a single admin.
Businesses that use NNT Mart in Košice
Popular online categories in Slovakia include electronics, fashion, sports, home and DIY, auto parts and cosmetics.

In Košice, we most often build mobile commerce apps for:

Take your Košice store onto customers' phones
Phones carry most traffic in Slovakia. Every app is published under your own Google Play and Apple developer accounts, with crash reporting, analytics and release management included.
Apps are published under your own developer accounts and share the same backend as your shopping app, so offers, stock and orders are always consistent between web and mobile.
Order alerts, offers and abandoned-cart reminders go out on Košice time (UTC+2), in Slovak and English if you want.
- Social login
- Firebase and push messaging
- Customer support chat
- Analytics and crash reporting
- Barcode and QR scanning
- Maps and location services
- Commerce APIs and headless backends
- Payment SDKs and wallets
Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.
From first demo to growth in Košice
We launch the journeys that create value first, then add depth. A typical roadmap for a shopping app in Košice:
| Phase | What goes live |
|---|---|
| MVP app | Core shopping, checkout, order tracking and push notifications. Configured for EUR, Visa and Mastercard and Slovenská pošta from the start. |
| Engage | Loyalty, referrals, personalised offers and deep links. |
| Extend | Dealer, delivery and admin apps on the same backend. Reviewed against how Košice 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.
Time zones, language and support
Košice runs on UTC+2, which is 3h 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 Slovak. 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; Košice clients are served remotely with on-site workshops when the project needs them.
