The case for a custom e-commerce platform in Austria

Austria is a market of about 9.0 million people where custom e-commerce platforms are growing fast, with Vienna as its capital.

Austria has SMEs make up 99% of all businesses in the European Union (European Commission). Austrian shoppers buy heavily from German platforms, so locally operated stores with Austrian delivery and eps payments build loyalty. Precise German content and invoice payment matter.

Shoppers and trade buyers in Austria already compare options on their phones; a custom e-commerce platform that loads fast, shows accurate stock and accepts eps bank transfer turns that research into orders.

What makes a Austria store feel local

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

Currency and pricing

Everything a Austria shopper sees — price, tax, delivery fee, refund — is in EUR, written the local way.

Language and content

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

Local trust signals

Trust is local: familiar names such as eps bank transfer and Klarna and invoice payment and Österreichische Post sit next to the buy button.

Domain, phone and contact

Using .at where it suits you signals a local business to shoppers and search engines. Contact buttons are pre-set with +43, so a customer in Austria taps once to call or message.

A custom e-commerce platform built around your Austria business

We do not hand Austria 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.

In Austria 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, sports and ski equipment and home that have strong online demand in Austria.

We start with a requirements meeting, show you a working demo within 24 hours, and only then propose scope, milestones and budget.

What your custom e-commerce platform includes

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. Product data imports from your existing sheets or ERP, so Austria teams do not re-type thousands of items.

Headless architecture

API-first commerce with a fast front end, so web, app, kiosk and marketplace channels share one backend. Customers in Austria can pay with eps bank transfer, Klarna and invoice payment and Visa and Mastercard, with receipts and refunds handled in the same admin.

Multi-entity operations

Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Delivery can be booked through Österreichische Post, DPD Austria and GLS or dispatched by your own riders around Austria.

Deep integrations

ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Inventory can sit in Austria, in a partner warehouse or across Austria, with click-and-collect where customers want it.

Migration

Move from older platforms with product, customer and order history, SEO-safe redirects and parallel runs. Revenue reports by product, repeat buyer and delivery area of Austria guide stock and marketing decisions.

Performance and security

Caching, CDN, load testing, security hardening, audit logs and cloud infrastructure as code. Pages, search filters and wording are tuned to how people in Austria look for products, in German if your audience needs it.

Industries in Austria we work with

Popular online categories in Austria include fashion, electronics, sports and ski equipment, home, books and organic food. In Austria, 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 Austria, 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 Austria, 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.

Checkout and payment methods for Austria

A custom e-commerce platform for Austria must support the way people here actually pay: eps bank transfer, Klarna and invoice payment, Visa and Mastercard, PayPal and Apple 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).

  • Eps bank transfer
  • Visa and Mastercard
  • PayPal
  • Klarna and invoice payment
  • Apple Pay

Fulfilment options for Austria orders

Your custom e-commerce platform can book shipments and share tracking with Österreichische Post, DPD Austria, GLS, DHL and Hermes, 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.

Marketplaces vs. your own custom e-commerce platform in Austria

Many Austria sellers already list on Amazon.de, willhaben, Zalando, Universal, MediaMarkt AT and shöpping.at. 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.

Tax, invoicing and compliance in Austria

Austrian VAT (USt) is 20% standard with 13% and 10% reduced rates.

Two frameworks shape the build: the EU General Data Protection Regulation (GDPR) and the ePrivacy rules on cookies and marketing consent, enforced by the Datenschutzbehörde, and the EU Consumer Rights Directive (14-day withdrawal right), the Digital Services Act and, from June 2025, the European Accessibility Act for online shops, the Austrian FAGG distance-selling act and the E-Commerce Act (ECG).

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.

Add a mobile app for Austria customers

Phones carry most traffic in Austria. 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 Austria time (UTC+2), in German if you want.

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

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

Value first, depth later. For a custom e-commerce platform serving Austria, the usual sequence looks like this:

PhaseWhat goes live
FoundationArchitecture, core commerce, priority integrations and migration. Configured for EUR, eps bank transfer and Österreichische Post from the start.
DifferentiateCustom workflows, configurators and automation.
OptimisePerformance, new channels, apps and continuous enhancement. Reviewed against how Austria customers actually buy.

We track page load and API response times, uptime, order-sync accuracy, manual-work hours saved, release frequency and total cost of ownership on a live dashboard from day one, so Austria results are visible, not promised.

Time zones, language and support

Our team covers UTC+2 — 3h 30m behind India (IST) — through three 8-hour shifts, so a Austria client always reaches someone during the local working day.

We work in English and can deliver storefront content in German. 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; clients in Austria are served remotely with on-site workshops when the project needs them.

How we work

How a custom e-commerce platform project runs with N&T Software for Austria

We do not sell a fixed template. Each custom e-commerce platform for businesses in Austria moves through seven gated stages, and nothing advances — and nothing is invoiced — until you have approved the working result.

    ✓ Scope signed off

You approve the working result before you pay

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:

After go-live: warranty, support and a team that stays

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.

Custom E-Commerce Development in Austria — FAQs

What sells best online in Austria?

Fashion, electronics, sports and ski equipment and home are strong online categories in Austria. We shape the catalogue, filters and checkout around what your own customers buy.

Can I also sell on Amazon.de and willhaben?

Yes. Your own custom e-commerce platform can sit alongside Amazon.de, willhaben and Zalando; where APIs allow, we sync products, stock and orders so your team manages everything from one admin.

Do you provide support after launch for clients in Austria?

Every project includes a free 90-day defect warranty, followed by an optional fixed-fee annual support package with a dedicated developer, SLA-based fixes and a 24×7 helpdesk across three shifts.

Which payment methods can my custom e-commerce platform accept in Austria?

We can integrate eps bank transfer, Klarna and invoice payment, Visa and Mastercard, PayPal and Apple Pay, subject to provider approval for your business category. Amounts are handled in euro.

Which parts of Austria do you build for?

the platform is not tied to one neighbourhood: delivery zones, pickup points and prices can be set for any part of Austria.

Can you migrate my existing website or store in Austria?

Yes. We review your current platform, products, customers, orders and URLs, then migrate with redirects so you keep search rankings and order history.

Do I own the source code of my custom e-commerce platform?

Yes. After full and final payment, 100% of the source code, design files, database schemas, deployment scripts and documentation are transferred to you, with no lock-in or forced subscription.

Is the platform compliant with local tax and privacy law in Austria?

We build the technical controls — tax-inclusive pricing, compliant invoices and consent management — with the EU General Data Protection Regulation (GDPR) and the ePrivacy rules on cookies and marketing consent in mind. Final legal and tax positions should be confirmed with your adviser.
