Why Sofia businesses are investing in mobile commerce apps
Sofia is a capital and largest city of bulgaria, home to about 1.2 million people, and one of the markets in Bulgaria where we build mobile commerce apps.
The local economy is driven by IT, outsourcing, finance, telecoms and services, and commercial activity concentrates around Business Park Sofia, Tsarigradsko Shose and the Vitosha Boulevard area.
Logistics are supported by Sofia Airport, Trakia motorway and the metro, which matters when you promise customers fast delivery.
Bulgaria has SMEs make up 99% of all businesses in the European Union (European Commission). Bulgaria has strong IT-literate shoppers, high cash-on-delivery use and a mature courier network (Econt and Speedy). Euro adoption in 2026 makes cross-border EU selling simpler for local stores.
Shoppers and trade buyers in Sofia already compare options on their phones; a shopping app that loads fast, shows accurate stock and accepts Visa and Mastercard turns that research into orders.
Localised for Sofia, not translated into it
Conversion in Sofia depends on small local signals — the right currency, the right words and the right payment and courier names.
Currency and pricing
The store speaks euro (adopted 1 January 2026; previously the lev): EUR amounts from product page to invoice, so Sofia buyers never convert in their heads.
Language and content
Storefront copy, product pages and emails can run in Bulgarian and English, with local date and number formats.
Local trust signals
We add the payment logos, courier names and policy pages shoppers in Sofia recognise: Visa and Mastercard and cash on delivery and delivery through Econt.
Domain, phone and contact
Using .bg where it suits you signals a local business to shoppers and search engines. Contact buttons are pre-set with +359, so a customer in Sofia taps once to call or message.
Talent and partners nearby
Sofia draws on Sofia University, Technical University of Sofia and the American University in Bulgaria, which means plenty of local staff, interns and technology partners to run the store after launch.
Designed to your requirements, not a template
Every NNT Mart shopping app in Sofia is engineered to the client's own brief — the web platform, the admin panel and, when you need one, a mobile application built for your workflow.
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 Bulgaria — electronics, fashion, home and garden and cosmetics — get catalogue structures and filters designed for them.
We start with a requirements meeting, show you a working demo within 24 hours, and only then propose scope, milestones and budget.
Features of your shopping app in Sofia
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. Product data imports from your existing sheets or ERP, so Sofia teams do not re-type thousands of items.
Dealer and B2B app
Account pricing, quick re-order, statements, schemes and barcode scanning for trade buyers. Checkout is configured for Visa and Mastercard, cash on delivery and Revolut.
Delivery partner app
Assigned orders, route navigation, proof of delivery, COD collection and status updates. Shipping rules can use Econt, Speedy and Bulgarian Posts as well as your own delivery staff in Sofia.
Store and admin app
Order alerts, stock updates, price changes and sales snapshots for owners and managers. Stock can be held in Sofia or anywhere in Bulgaria, with pickup and local-delivery options where they make sense.
Engagement
Segmented push notifications, deep links, in-app banners, loyalty and referral programmes. Revenue reports by product, repeat buyer and delivery area of Sofia guide stock and marketing decisions.
Performance and offline
Fast native-feel UI, image caching, offline cart and graceful handling of poor networks. Content and design can follow how customers in Sofia search and buy, including Bulgarian and English where you need it.
Industries in Sofia we work with
Popular online categories in Bulgaria include electronics, fashion, home and garden, cosmetics, auto parts and food products. Local demand in Sofia is shaped by IT, outsourcing, finance, telecoms and services, so we often design catalogues and B2B ordering around those sectors. In Sofia, 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 Sofia, 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 Sofia customers pay online
A store that serves Sofia should let customers pay the way they do offline: Visa and Mastercard, cash on delivery, Revolut and bank transfer.
Gateway selection depends on your category and merchant approval; we connect the provider, reconcile payments, automate retries and refunds, and never store raw card data. Prices, taxes and refunds appear in euro (adopted 1 January 2026; previously the lev) (EUR).
Zone-based payment rules let you offer different options for Business Park Sofia than for outer parts of Sofia.
- EPay.bg
- Bank transfer
- Cash on delivery
- Visa and Mastercard
- Apple Pay and Google Pay
- Revolut
Shipping, couriers and local delivery in Sofia
Your shopping app can book shipments and share tracking with Econt, Speedy, Bulgarian Posts, DHL, Sameday and Box Now lockers, or route orders to your own riders and stores across Sofia.
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 — Sofia Airport, Trakia motorway and the metro — makes regional and national dispatch from Sofia practical.
Your own store alongside eMAG.bg and OLX.bg
For a Sofia business, eMAG.bg, OLX.bg, Amazon.de and Temu are useful shop windows — but fees, ranking changes and shared customer data limit how far you can grow on them alone.
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 Bulgaria
Tax basics: Bulgaria charges 20% VAT (9% on tourism, 0% on certain items) and participates in the EU One-Stop Shop for cross-border B2C sales.
Two frameworks shape the build: the GDPR, enforced nationally by the Commission for Personal Data Protection (CPDP), and the Consumer Protection Act and the Electronic Commerce Act, which set 14-day withdrawal and mandatory pre-contract information.
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 Bulgaria.
Android and iOS apps for your Sofia business
Phones carry most traffic in Bulgaria. 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.
Push notifications can be timed to UTC+3 so offers reach Sofia customers when they are awake, and the interface can run in Bulgarian and English.
- Social login
- Payment SDKs and wallets
- Customer support chat
- Firebase and push messaging
- Maps and location services
- Commerce APIs and headless backends
- Analytics and crash reporting
- Barcode and QR scanning
Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.
How we phase your shopping app
Value first, depth later. For a shopping app serving Sofia, the usual sequence looks like this:
| Phase | What goes live |
|---|---|
| MVP app | Core shopping, checkout, order tracking and push notifications. Configured for EUR, Visa and Mastercard and Econt from the start. |
| Engage | Loyalty, referrals, personalised offers and deep links. |
| Extend | Dealer, delivery and admin apps on the same backend. Reviewed against how Sofia 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
Sofia 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 Bulgarian. 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; Sofia clients are served remotely with on-site workshops when the project needs them.
