Why Belgium businesses are investing in custom e-commerce platforms

Belgium is a market of about 12 million people where custom e-commerce platforms are growing fast, with Brussels as its capital.

Belgium has SMEs make up 99% of all businesses in the European Union (European Commission). Belgian shoppers expect bilingual Dutch/French stores and Bancontact at checkout. Many still buy from Dutch and French sites, so local stock and fast delivery are a real edge.

For a business in Belgium, the opportunity is to own the customer relationship: your own custom e-commerce platform keeps your margin, your data and your brand, while marketplaces and social channels become additional sales routes instead of the only one.

Local details we build into every Belgium project

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

Currency and pricing

The store speaks euro: EUR amounts from product page to invoice, so Belgium buyers never convert in their heads.

Language and content

Content can be produced in Dutch, French and German, so a Belgium 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 Belgium recognise: Bancontact and Visa and Mastercard and delivery through bpost.

Domain, phone and contact

Using .be where it suits you signals a local business to shoppers and search engines. Click-to-call and WhatsApp buttons use the +32 calling code so customers reach you without dialling errors.

Custom-built for how you sell in Belgium

Your custom e-commerce platform is planned, designed and coded for your business model — not adapted from someone else's — and it can ship with a customer or staff mobile app on day one.

In Belgium 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, food and chocolate and home that have strong online demand in Belgium.

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

These are the building blocks of a custom e-commerce platform. We scope them with you, so you pay for what your Belgium operation needs.

Custom workflows

Product configurators, made-to-order flows, approvals, contracts and industry-specific rules. Multiple stock points in Belgium are supported, so a Belgium order ships from the nearest one.

Headless architecture

API-first commerce with a fast front end, so web, app, kiosk and marketplace channels share one backend. Revenue reports by product, repeat buyer and delivery area of Belgium guide stock and marketing decisions.

Multi-entity operations

Multiple brands, companies, warehouses, currencies and tax registrations on one platform. Storefront language, imagery and navigation are set up for Belgium shoppers and available in Dutch and French.

Deep integrations

ERP, PIM, WMS, CRM, POS, accounting and legacy systems with reliable, monitored data sync. Catalogues come in from spreadsheets, ERP exports or supplier feeds, so your Belgium team keeps its current way of working.

Migration

Move from older platforms with product, customer and order history, SEO-safe redirects and parallel runs. Payment steps are built around Bancontact, Visa and Mastercard and PayPal, the options shoppers here already trust.

Performance and security

Caching, CDN, load testing, security hardening, audit logs and cloud infrastructure as code. Shipping rules can use bpost, PostNL Belgium and DPD as well as your own delivery staff in Belgium.

Getting paid online in Belgium

A custom e-commerce platform for Belgium must support the way people here actually pay: Bancontact, Visa and Mastercard, PayPal, Payconiq, Apple Pay and KBC/CBC Pay.

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 (EUR).

  • KBC/CBC Pay
  • Visa and Mastercard
  • Apple Pay
  • Bancontact
  • Payconiq
  • PayPal

Shipping, couriers and local delivery in Belgium

Your custom e-commerce platform can book shipments and share tracking with bpost, PostNL Belgium, DPD, GLS, DHL and Mondial Relay, or route orders to your own riders and stores.

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.

Compliance built into your custom e-commerce platform

On tax: Belgian VAT is 21% standard with 12% and 6% reduced rates; B2B e-invoicing via Peppol is mandatory from 2026.

Two frameworks shape the build: the EU General Data Protection Regulation (GDPR) and the ePrivacy rules on cookies and marketing consent, enforced by the Belgian Data Protection Authority, 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 and Book VI of the Code of Economic Law.

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.

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

Bol, Amazon (FR/NL/DE) and Coolblue are where many shoppers in Belgium start, which is why sellers list there. The trade-off is commission, limited branding and rules the platform can change overnight.

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.

Industries in Belgium we work with

Popular online categories in Belgium include fashion, electronics, food and chocolate, home, beauty and books. In Belgium, 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 Belgium, 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 Belgium, 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.

Android and iOS apps for your Belgium business

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+2 so offers reach Belgium customers when they are awake, and the interface can run in Dutch and French.

  • WMS and 3PL systems
  • Identity and SSO
  • Search engines (Elasticsearch, Algolia)
  • PIM and DAM
  • BI and data warehouses
  • POS and store systems
  • Cloud platforms (AWS, Azure, GCP)
  • 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.

Launch roadmap and success metrics

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

PhaseWhat goes live
FoundationArchitecture, core commerce, priority integrations and migration. Configured for EUR, Bancontact and bpost from the start.
DifferentiateCustom workflows, configurators and automation.
OptimisePerformance, new channels, apps and continuous enhancement. Reviewed against how Belgium customers actually buy.

Success is measured on page load and API response times, uptime, order-sync accuracy, manual-work hours saved, release frequency and total cost of ownership — tracked on a dashboard you can see from launch day.

How Belgium clients work with us

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

Project communication is in English; storefront content can be produced in Dutch, German and French. 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; clients in Belgium are served remotely with on-site workshops when the project needs them.

A milestone payment plan built around acceptance

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:

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.

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.

Custom E-Commerce Development in Belgium — FAQs

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

We can integrate Bancontact, Visa and Mastercard, PayPal, Payconiq, Apple Pay and KBC/CBC Pay, subject to provider approval for your business category. Amounts are handled in euro.

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

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.

Which couriers do you integrate for deliveries from Belgium?

Common choices are bpost, PostNL Belgium, DPD, GLS, DHL and Mondial Relay. We can also route orders to your own riders, stores or warehouses and set rules by zone, weight or delivery slot.

Can I also sell on Bol and Amazon (FR/NL/DE)?

Yes. Your own custom e-commerce platform can sit alongside Bol, Amazon (FR/NL/DE) and Coolblue; where APIs allow, we sync products, stock and orders so your team manages everything from one admin.

What sells best online in Belgium?

Fashion, electronics, food and chocolate and home are strong online categories in Belgium. We shape the catalogue, filters and checkout around what your own customers buy.

Do you provide support after launch for clients in Belgium?

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.

How much does a custom e-commerce platform cost in Belgium?

There is no fixed package price: every NNT Mart custom e-commerce platform is quoted to your requirements and budget after a free requirements meeting and demo. Cost depends on catalogue size, integrations, payment and delivery rules, mobile apps and support. Payments are split into milestones, and 90% is released only after you accept working modules.

Can you build a mobile app along with the custom e-commerce platform for my Belgium business?

Yes. We build Android and iOS apps for customers, dealers, delivery staff or administrators on the same backend as your custom e-commerce platform, and publish them under your own Google Play and App Store accounts.
