Why Szczecin businesses are investing in multi-vendor marketplaces

Szczecin is a capital city of west pomerania, poland, with a population of roughly 388,000, and one of the markets in Poland where we build multi-vendor marketplaces.

Key sectors include port logistics and shared services, with business districts such as the city centre and port.

Logistics are supported by Port of Szczecin, which matters when you promise customers fast delivery.

Poland has SMEs make up 99% of all businesses in the European Union (European Commission). Poland is one of Europe's fastest-growing e-commerce markets, with BLIK and InPost lockers used by most online shoppers. Integrating with Allegro alongside your own store is common.

Shoppers and trade buyers in Szczecin already compare options on their phones; a multi-vendor marketplace that loads fast, shows accurate stock and accepts BLIK turns that research into orders.

What makes a Szczecin store feel local

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

Currency and pricing

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

Language and content

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

Local trust signals

Badges for BLIK and Przelewy24 bank transfers, InPost Paczkomat delivery and clear return terms reassure first-time buyers in Szczecin.

Domain, phone and contact

A .pl domain (or your own) builds local trust and search relevance. Click-to-call and WhatsApp buttons use the +48 calling code so customers reach you without dialling errors.

Talent and partners nearby

With West Pomeranian University of Technology close by, finding people to manage catalogues, content and support after launch is realistic in Szczecin.

A multi-vendor marketplace built around your Szczecin business

Whatever your business sells in Szczecin, N&T Software designs and develops the multi-vendor marketplace and the matching mobile app exactly to your requirements — your catalogue, your prices, your payment and delivery rules.

Typical clients include regional seller networks, B2B supplier platforms, service-provider marketplaces and institutional procurement platforms. Categories that sell especially well online in Poland — fashion, electronics, home and garden and automotive parts — 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.

What your multi-vendor marketplace includes

These are the building blocks of a multi-vendor marketplace. We scope them with you, so you pay for what your Szczecin operation needs.

Vendor onboarding

Application, document verification, agreements, approval and seller dashboards with team access. Product data imports from your existing sheets or ERP, so Szczecin teams do not re-type thousands of items.

Catalogue governance

Listing templates, moderation queues, category rules, image standards and duplicate detection. Checkout is configured for BLIK, Przelewy24 bank transfers and Visa and Mastercard.

Commission engine

Commissions and fees by vendor, category, product or transaction, with promotions funded by either party. Delivery can be booked through InPost Paczkomat, Poczta Polska and DPD Polska or dispatched by your own riders around Szczecin.

Order routing

Split carts, vendor-wise fulfilment, shipping rules, service areas and delivery tracking. Stock can be held in Szczecin or anywhere in Poland, with pickup and local-delivery options where they make sense.

Settlements

Payout calculations, reconciliation reports and integration with split-payment providers where permitted. Revenue reports by product, repeat buyer and delivery area of Szczecin guide stock and marketing decisions.

Trust and support

Ratings, reviews, returns, disputes, seller performance scores and customer-support workflows. Pages, search filters and wording are tuned to how people in Szczecin look for products, in Polish if your audience needs it.

Checkout and payment methods for Szczecin

A multi-vendor marketplace for Szczecin must support the way people here actually pay: BLIK, Przelewy24 bank transfers, Visa and Mastercard, PayPo deferred payment, Google Pay and cash on delivery.

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 Polish złoty (PLN).

For Szczecin customers ordering from the city centre and port, cash-on-delivery and pay-on-pickup rules can be set per delivery zone.

  • Visa and Mastercard
  • BLIK
  • Google Pay
  • PayPo deferred payment
  • Cash on delivery
  • Przelewy24 bank transfers

Fulfilment options for Szczecin orders

Your multi-vendor marketplace can book shipments and share tracking with InPost Paczkomat, Poczta Polska, DPD Polska, DHL Parcel, GLS and Orlen Paczka, or route orders to your own riders and stores across Szczecin.

We set up shipping zones, cut-off times, free-shipping thresholds, cash-collection rules and returns so the promise on the product page matches what your team can deliver.

Connectivity in the area — Port of Szczecin — makes regional and national dispatch from Szczecin practical.

Tax, invoicing and compliance in Poland

Tax basics: Polish VAT is 23% standard with 8% and 5% reduced rates; the national KSeF e-invoicing system becomes mandatory in 2026.

Customer data is handled with the EU General Data Protection Regulation (GDPR) and the ePrivacy rules on cookies and marketing consent, enforced by UODO in mind, and the storefront follows 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 the Polish Consumer Rights Act.

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 Szczecin.

Marketplaces vs. your own multi-vendor marketplace in Szczecin

For a Szczecin business, Allegro, Amazon.pl, Temu and OLX are useful shop windows — but fees, ranking changes and shared customer data limit how far you can grow on them alone.

With your own multi-vendor marketplace 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 Szczecin

Popular online categories in Poland include fashion, electronics, home and garden, automotive parts, beauty and children's products. Local demand in Szczecin is shaped by port logistics and shared services, so we often design catalogues and B2B ordering around those sectors. In Szczecin, we most often build multi-vendor marketplaces for:

Industry-specific marketplaces

For industry-specific marketplaces, we usually start with catalogue governance, then add split-payment and escrow providers once orders are flowing.

Regional seller networks

Catalogue, pricing and fulfilment rules designed for regional seller networks in Szczecin, connected to the systems you already use.

B2B supplier platforms

B2B supplier platforms get commission engine plus settlements workflows tailored to their operations.

Service-provider marketplaces

We map how service-provider marketplaces sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

Institutional procurement platforms

For institutional procurement platforms, we usually start with trust and support, then add search and recommendation engines once orders are flowing.

Artisan and curated brand marketplaces

Catalogue, pricing and fulfilment rules designed for artisan and curated brand marketplaces in Szczecin, connected to the systems you already use.

Add a mobile app for Szczecin customers

Phones carry most traffic in Poland. Separate buyer and seller apps let customers shop and track orders while vendors manage listings, accept orders and see payouts from their phones.

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 Szczecin time (UTC+2), in Polish if you want.

  • WhatsApp and push notifications
  • CRM and helpdesk
  • KYC and business verification
  • Tax and invoicing systems
  • Search and recommendation engines
  • Split-payment and escrow providers
  • Logistics aggregators
  • Analytics and BI

Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.

Pay only for work you have accepted

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 multi-vendor marketplace:

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 multi-vendor marketplace keeps it secure, updated and running on a fixed annual fee agreed up front — no open-ended hourly billing and no surprise invoices.

100% of the source code and IP is owned by you

For every multi-vendor marketplace, 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.
