Why a custom e-commerce platform makes sense for Thessaloniki

Thessaloniki is a second-largest city in greece, home to about 310,000 people, and one of the markets in Greece where we build custom e-commerce platforms.

Businesses here work in logistics, port and tech hub; many are based around the city centre and Thessaloniki Technology Park.

Logistics are supported by Thessaloniki Airport and port, which matters when you promise customers fast delivery.

Greece has SMEs make up 99% of all businesses in the European Union (European Commission). Greek shoppers research heavily on Skroutz and expect cash-on-delivery and IRIS options. Island delivery rules and Greek-language product content are important.

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

Local details we build into every Thessaloniki project

Conversion in Thessaloniki depends on small local signals — the right currency, the right words and the right payment and courier names.

Currency and pricing

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

Language and content

Content can be produced in Greek, so a Thessaloniki customer reads the store in the language they use at home.

Local trust signals

We add the payment logos, courier names and policy pages shoppers in Thessaloniki recognise: Visa and Mastercard and IRIS instant payments and delivery through ELTA Courier.

Domain, phone and contact

Using .gr where it suits you signals a local business to shoppers and search engines. Click-to-call and WhatsApp buttons use the +30 calling code so customers reach you without dialling errors.

Talent and partners nearby

Thessaloniki draws on Aristotle University of Thessaloniki, which means plenty of local staff, interns and technology partners to run the store after launch.

Designed to your requirements, not a template

If you run a business in Thessaloniki 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 Thessaloniki 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 electronics, fashion, beauty and home that have strong online demand in Greece.

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 Thessaloniki 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. Product data imports from your existing sheets or ERP, so Thessaloniki 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 Thessaloniki can pay with Visa and Mastercard, IRIS instant payments and PayPal, with receipts and refunds handled in the same admin.

Multi-entity operations

Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Shipping rules can use ELTA Courier, ACS and Geniki Taxydromiki as well as your own delivery staff in Thessaloniki.

Deep integrations

ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Stock can be held in Thessaloniki or anywhere in Greece, with pickup and local-delivery options where they make sense.

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 Thessaloniki 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 Thessaloniki look for products, in Greek if your audience needs it.

Industries in Thessaloniki we work with

Popular online categories in Greece include electronics, fashion, beauty, home, food and olive oil and tourism products. Local demand in Thessaloniki is shaped by logistics, port and tech hub, so we often design catalogues and B2B ordering around those sectors. In Thessaloniki, 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 Thessaloniki, 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 Thessaloniki, 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 Thessaloniki

Checkout is where most online sales are won or lost. In Greece, customers expect to pay with Visa and Mastercard, IRIS instant payments and PayPal, and many also look for cash on delivery (antikatavoli), bank transfer and Klarna.

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.

  • IRIS instant payments
  • Bank transfer
  • Klarna
  • Cash on delivery (antikatavoli)
  • Visa and Mastercard
  • PayPal

Shipping, couriers and local delivery in Thessaloniki

Your custom e-commerce platform can book shipments and share tracking with ELTA Courier, ACS, Geniki Taxydromiki, Speedex and BOX NOW lockers, or route orders to your own riders and stores across Thessaloniki.

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 — Thessaloniki Airport and port — makes regional and national dispatch from Thessaloniki practical.

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

For a Thessaloniki business, Skroutz, Public, Plaisio and Kotsovolos are useful shop windows — but fees, ranking changes and shared customer data limit how far you can grow on them alone.

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.

Compliance built into your custom e-commerce platform

Greek VAT (FPA) is 24% standard with 13% and 6% reduced rates, and lower rates on some Aegean islands.

On privacy we design around the EU General Data Protection Regulation (GDPR) and the ePrivacy rules on cookies and marketing consent, enforced by the Hellenic Data Protection Authority; on consumer rights the store reflects the EU Consumer Rights Directive (14-day withdrawal right), the Digital Services Act and, from June 2025, the European Accessibility Act for online shops and Law 2251/1994 on consumer protection.

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 Greece.

Take your Thessaloniki store onto customers' phones

Phones carry most traffic in Greece. 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.

Push notifications can be timed to UTC+3 so offers reach Thessaloniki customers when they are awake, and the interface can run in Greek.

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

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 Thessaloniki

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

PhaseWhat goes live
FoundationArchitecture, core commerce, priority integrations and migration. Configured for EUR, Visa and Mastercard and ELTA Courier from the start.
DifferentiateCustom workflows, configurators and automation.
OptimisePerformance, new channels, apps and continuous enhancement. Reviewed against how Thessaloniki 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 Thessaloniki results are visible, not promised.

Time zones, language and support

Thessaloniki 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.

Project communication is in English; storefront content can be produced in Greek. You get a named lead, direct engineer access and an NDA if you ask.

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

Pay only for work you have accepted

There is no standard price list, because every custom e-commerce platform is quoted to your requirements and budget. What is standard is how you pay: a small advance, then milestones released only after written acceptance. An example:

Protected after launch — warranty and annual support for your custom e-commerce platform

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.

You own the code, the data and the IP

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.
